Climate Justice: Vulnerability Assessment in a coastal urban poor settlement in India

Vulnerability is an indicator of the possibility of harm that might affect an individual, community or region. It is multi-dimensional, differential, scale-dependent and dynamic, as it depends on time, space, and units of analysis. Within the realm of climate science, vulnerability has been understood as an intangible yet extremely crucial factor to determine the future risks. It cannot be understood purely in relation to the impacts of climate change or a natural hazard, instead, it needs to integrate social systems. Thus, through YUVA’s Climate Justice Project, a climate vulnerability assessment in an urban poor community in Mumbai, India was conducted. We used tools of mapping to understanding existing climate vulnerabilities like heat, flooding and cyclones. Through QGIS we overlaid community-based qualitative mapping with historical maps and climate hazard maps. Through this we seek to develop a Community Climate Action Plan guiding towards community-based Climate Adaptations.

Quantifying warming data

Global warming is real and while the world is living through this phenomenon everyday, what happens when the world actually breaches the 1.5°C threshold? We do know how the Arctic region and Europe will be hardest-hit but what about other regions and countries? Through this workshop, by quantifying IPCC’s latest geospatial data, attendees would be able to give a number instead of dealing in abstracts. By incorporating the ‘zonal statistics’ method, anyone can visualize spatial data in matter of seconds and give more context to it like when the world breaches the 1.5°C bar, your country would be warming at? India would be warming at 1.2°C.

Airport local air quality studies using QGIS

Air pollution continues to be the number one environmental health problem in the EU. Airport and all associated aircraft activities are sources of an assortment of gaseous and particulate emissions. However, aviation is not the only, and quite often not even the major contributor to local air pollution. Developed as a plug-in to QGIS, Eurocontrol's Airport Local Air Quality Studies (Open-ALAQS) modelling tool can estimate emissions from aircraft operation and various airport and non-airport emission sources, such as road traffic and industrial facilities, that are known to contribute to the degradation of local air-quality.

Imaging spectroscopy data in QGIS: challenges and opportunities

Satellite missions like EnMAP (Chabrillat, 2022) and PRISMA (Cogliati et al., 2021) observe the Earth surface with hyperspectral resolution. The provided imaging spectroscopy data is highly valuable for biophysical, agricultural, geological hydrological applications. This presentation gives an overview on the typical characteristics of such imaging spectroscopy raster data, where to get it for free, and what makes it different to data from satellites like Landsat and Sentinel-2. We show typical problems that QGIS users and developers are confronted with when using imaging spectroscopy data, and how these problems can be solved exemplary using the EnMAP-Box plugin (Janz et al., 2023). Finally, we discuss conceptional ideas how QGIS could be enhanced to better exploit the spectral dimension in multi-, super- and hyperspectral raster data.

State of the PCRaster Tools plugin

PCRaster is a powerful package of software for map algebra and environmental dynamic modelling. The main applications of PCRaster are found in environmental modelling. In the PCRaster package a rich suite of geomorphological and hydrological functions is available. These include functions for visibility analysis, catchment analysis and routing of transport (drainage) of material in a catchment using interactively generated local drain direction maps and transport (routing) operations. These operations are made available in the QGIS Processing Toolbox through the PCRaster Tools plugin. This presentation will show applications, the current state of the plugin and the plans for the future.

Spatially filtering your project's layers for more efficient workflows

A new plugin "Räumlicher Filter" allows to spatially filter the layers of a QGIS project quickly and dynamically to specific spatial regions. This can dramatically enhance user experience as it not only speeds up data access (only data of the region(s) has to be fetched from the data source) but also makes spatially constrained analysis or exports a walk in the park.
The plugin currently supports PostGIS, GeoPackage and Spatialite layers and has features like:
- Existing (e.g. municipalities) or manually drawn geometries can be used as filter regions
- Filters can be named and stored for easy re-use
- The geometric predicate can be selected (currently „intersects“, „within“ or „disjoint“)
- Layers can be excluded from filtering

Publishing difficult? Not with the Bridge plugin!

Publishing your map to web services such as GeoServer or MapServer takes quite a bit of effort. At least, without the plug-in GeoCat Bridge for QGIS.

With Bridge, you no longer have to upload each layer and style separately; instead, you can publish the data, style and metadata all at once. In addition, the StyleViewer translates the style to SLD, MapServer, MapBox or GeoStyler format.

We will show you the difference between publishing with or without Bridge and how to publish multiple styled map layers at once to GeoServer or MapServer, while at the same time the metadata will be published to a GeoNetwork portal.

Pedometrics and Digital Soil Mapping in QGIS

Pedometrics and Digital Soil Mapping are two important areas of research in soil science that have been gaining increasing attention in recent years. While QGIS is a popular open-source GIS software that is often used in soil analysis and mapping, R language is a powerful statistical programming language that offers a wide range of tools for data analysis and visualization.

The integration of QGIS with R language provides soil scientists with a powerful toolset for soil analysis and mapping. R can be used to process, analyze, and visualize soil data, and the results can be integrated into QGIS for mapping and visualization. In this way, R can enhance the capabilities of QGIS and provide more advanced analysis and modeling capabilities.

This presentation presents an overview of the combination of Pedometrics, Digital Soil Mapping, QGIS, and R language for soil analysis and mapping. It discusses the various techniques and tools available in R for soil analysis, as well as how R can be integrated with QGIS for advanced mapping and visualization. The paper also provides some case studies where this combination of tools has been used to map and analyze soil properties. Overall, the integration of QGIS with R language offers great potential for advancing soil science research and applications.

Introducing Spectral Properties for Earth Observation Data for Interactive Visualization in the EnMAP-Box 3 Plugin

The EnMAP-Box (Janz et al., 2023) is a Python based QGIS plugin that greatly enhances the support for freely available Earth observation data. It directly supports, widely used, multispectral Landsat 4-9 and Sentinel-2 imagery, as well as the more recently introduced hyperspectral imagery from the EnMAP, DESIS and PRISMA satellite missions.
With the introduction of spectral band properties, we allow the (user-friendly) visual exploration, analysis and harmonization of imagery from different optical sensors at the same time. The simplest form of a spectral band property would be the center wavelength, e.g. Near Infrared band at around 830 nm. A proper center wavelength annotation allows for the selection of prominent RGB band combinations like colored infrared, the proper visualization of spectral pixel profiles, the derivation of spectral indices and spectral resampling from one sensor characteristic into another.

Point clouds in QGIS: Now with Processing integration!

Point clouds are an increasingly popular data type thanks to the decreasing cost of their acquisition through lidar surveys and photogrammetry. On top of that, more and more national mapping agencies release high resolution point cloud data (spanning large areas and consisting of billions of points), unlocking many new use cases.

This talk will summarize where we are in terms of support for point cloud data in QGIS since their introduction two years ago in the 3.18 release and what landed in QGIS since then. In addition to that, we will have a look at the upcoming addition of tools for point cloud analysis right from QGIS Processing toolbox: clip, filter, merge, export to raster, extract boundaries and more - all backed by PDAL library that already ships with QGIS, without having to rely on third party proprietary software.

Advanced workflows with Mergin Maps

The Mergin Maps project comes with a promise to make field data collection with QGIS easy,
but it offers more than just a mobile app for fieldwork. In this talk, we will look

the use of a mobile app at all.

Among the topics this session will cover:
- data synchronization with a PostGIS database
- splitting data into work packages for multiple teams
- publishing web maps
- moving pictures to a cloud storage
- hosting your own Mergin Maps server
- using Python API.

Basic understanding of Mergin Maps is recommended for this talk.

Equity Assessment in Transboundary Water Resources Management Using Remote Sensing Data and QGIS

This study aims to develop a conceptual framework to assess and quantify equity using open access remote sensing hydrological data and QGIS for transboundary water resources of the Nile basin. Transboundary water management is a complex issue that requires a multi-faceted approach to ensure equitable distribution of water resources. The shortage of materials and methods to assess equity to help riparian countries establish operational arrangements for transboundary water management made it difficult to understand the demand and use of water in the basin, and thus created conflicts. By analysing satellite imagery and other data sources, QGIS can help to identify areas where water resources are scarce and where demand for water may be exceeding supply. The results of this study can be used to develop policies and promote cooperation and more equitable water management practices.

QGIS.org - The importance of seeding

QGIS turned 20 years old last year. The first lines of code were written in mid-February 2002 and when the programme was first compiled and run, it could do exactly one thing:
Connect to a PostGIS database and draw a vector layer.

Nowadays, QGIS is the go-to GIS solution for millions of users, and to make sure that QGIS's future is as bright as its past, we did a lot of work on communication, strategy and outreach.
In this talk, I’ll overview all the work done and the future of QGIS.

QField and QFieldCloud - collaborate efficiently in the field

QField is the field data collection app for QGIS with more than 175K active users and well over 650K downloads. QFieldCloud is the sync platform for QField and QGIS released in early 2023.

In this workshop we will go through the complete fieldwork process: setting up your QGIS project, publishing the project via QFieldCloud, collecting data via the QField mobile app and synchronising the field data back to your main dataset in the office.
QField works on top of QGIS and allows users to set up maps and forms in QGIS on their workstation and deploy them in the field. QField uses QGIS's data providers - OGR, GDAL, PostGIS and others - and supports most common file formats.
QField combines a minimal design with sophisticated technology that allows intuitive viewing and editing of data. QField's map rendering is supported by the QGIS rendering engine, so the results are identical and the full range of styling options available on the desktop is available. Editing forms in QField respect the QGIS configuration and are optimised for touch interaction.
QFieldCloud will also make field collaboration much easier. We will learn about configuring users with different rights, offline and online data collection, and synchronisation of field data and QGIS project data.

We are a urban planning consultance firm (Generation.energy / PosadMaxwan). At our office we work in project teams on projects that have almost always an important GIS component. We work from different locations and need to have an environment so that we can work together on GIS projects. This is achieved with a QGIS desktop - Postgresql setup where we store data, styles and projects in the database.

Geospatial Data Science Certifcate: Using QGIS in the Classroom

The Geospatial Data Science Certificate started in March 2022 as a pilot project aimed at introducing the practical components of GIS. In South Africa, GIS in the classroom is textbook-based, and learners do not get to explore the various GIS packages available. The GDSC’s vision is to expose the learners to the GIS packages they can use in the classroom. The material given to learners combines topics learnt in the classroom and how they can map and visualise the topic in QGIS. In 2022, the project was divided into two parts, Part A, which is the training and instruction component of the certificate task; and Part B which is the group and research component of the certificate task.

Geopackage and Filegdb developments in QGIS

Together with Provincie Gelderland a number of regional and local governments in the Netherlands have joined forces to enhance the exchange capabilities of the most used geo-databases namely Geopackage and Filegdb in QGIS. The reason for this development is that in order to have an effective assetmanagement process we need to exchange asset information in a project during the pre and post execution phase. We are only interested in the assetdata so we want to take away as many restrictions posed by proprietary formats or unsupported features of an open format.

Testing Spatial Data using QGIS and PyTest

Do we need testing Data itself or rather Big Data or rather better Geospatial Big Data during rapid technological changes resulting increasing collecting of geographical information no matter how, everywhere, every time? If data quality is important for us, the answer is yes.
But how to keep high quality of geospatial data and detect potential bugs as quick as possible? The answer is merging two open-sources and powerful software. First is QGIS API which is crucial to reading/writing and operate on geospatial data. Second is PyTest – very popular and easy to implement python testing framework.
The main purpose of the presentation is sharing knowledge how to use above technologies to design testing strategy and test cases, execute tests with high performance and generate test reports with visual representation of defects on map.

CALCULATION OF WATER BALANCE THROUGH SPATIAL DATA MODELING, IN THE MOTATAN RIVER BASIN, TRUJILLO STATE, VENEZUELA.

In the present work, the methodological process to calculate the monthly average water balance for a hydrographic basin located in the Paramos de Motatan and extends to the Trujillo state is exposed, the objective was to evaluate the importance of the water dynamics. The procedure uses GIS tools to develop the surface water balance according to the classic Thornthwaite methodology, which allows calculating the variables of the water system based on the definition of the maximum available water capacity on the ground (CAD), the measurements (average or total) of precipitation and the estimate of potential evapotranspiration following the methodology proposed by Thornthwaite. In the GIS-Qgis environment it was possible to perform the water balance by applying map algebra to continuous surfaces. The intermediate and final products of this simulation exercise are raster layers or spatio-temporal matrices that represent the average water condition at temporal (monthly) and spatial (pixel) scales in the study basin. Based on the results, it is evaluated that the proposed methodology presents satisfactory results and can be applied to other units of analysis of broader scales.

This research article includes the review of 35 publications on the various aspects of the applications of geospatial technology in water science, the articles are one of the best investigations in the analysis of the various conflicts over the use of water in the society, the same by virtue of the needs of society in the constant search to value, explore, describe, for purposes of preservation and optimize the management of water supply, reuse and treatment and therefore of water resources to achieve sustainability of access to water and sanitation focusing on the quality, availability and management of freshwater resources, to ensure environmental suitability as part of the United Nations Millennium Development Goal-7. The volume will serve as a compendium on the applications of geospatial technology in various aspects of vulnerability and social risk due to access to water and the various conflicts generated in most cases by the effect of anthropogenic actions.

Using QGIS and PostGIS to map mobile "Dead spots" for potential government funding

The combination of QGIS and PostGIS is an important tool to map and prioritise mobile „Dead Spots“ for potential funding by the German Government. In order to achieve the goal “Where people are, there should be mobile access” there are several working steps and, just as important, stakeholder involvement, which are carried out by the MIG (Mobilfunkinfrastrukturgesellschaft) in Naumburg (Saale). These steps include the acquisition of mobile coverage forecasts from all four mobile network providers, alignment with existing and obligatory mobile expansion programs and area prioritisation according to number of households, roads, rail, land use, points of interest and other features playing a role in the assessment of potential funding. These are then evaluated by network and site planners and submitted to the network providers for potential interest.

Using QFieldCloud for geological data collection

The application ‘QField’ was found to be the most suitable for the branch’s specific needs, therefore a thorough process was followed to better understand the main functions of the application and how to customize it to fully suit the branch’s data requirements. One of the most crucial steps initially was to identify the specific type of geoscientific data to be collected by the Geologists of the branch during general field programs. Based on these data requirements, data templates were customized within QGIS and later packaged for use in the QField application for any field project. This should ideally make the data collection process more efficient and reduce human error during the data capture.

MISE EN PLACE D’UN SYSTEME DE CONSULTATION DES DONNEES CADASTRALES : DEMATERIALISATION ET VALORISATION DES ANCIENS PLANS CADASTRAUX DES VILLES DU CAMEROUN

Il s’agira pour nous de présenter une approche SIG adoptée avec le logiciel QGIS dans le cadre du projet de dématérialisation des anciens plans cadastraux de 1986, de quatre villes du Cameroun. En Afrique, les initiatives pour améliorer la gestion du cadastre souffrent de l’insuffisance de stratégie, de coordination des acteurs et surtout de prévisibilité des moyens mobilisés. La culture papier reste prédominante faute de compréhension suffisante et de maîtrise de l’apport d’une dématérialisation des documents. L’intérêt de notre projet est donc majeur puisqu’il a permis la reconstitution rapide du cadastre sur le plan national en général et dans les villes de forte urbanisation en particulier.

Being a big Open Source project: a discussion with QGIS and Blender

In this discussion panel some yet-to-be-determined QGISsers talk with Sybren A. Stüvel from Blender about the many aspects of working on - and being - a big Open Source project. The goal is to discuss and exchange ideas, not just between the pannelists but also with the audience.

Politics and QGIS: open source legislative reapportionment

Once the realm of expensive commercial software, QGIS is now being used to reapportion political boundaries in different countries, especially for legislative districts. This discussion will demonstrate how the QGIS redistricting tool works and describe how it has been used in practice to redraw American and Australian political districts.

How QGIS assists the humanitarian work of Red Cross

The presentation will showcase how QGIS is used in various humanitarian operations by the Red Cross and Red Crescent movements. It will show the use cases in emergencies as well as concrete examples of how it assisted decision-making in complex disasters (such as Ukraine crisis). It will also discuss how QGIS plugins developed by professional volunteers and 510 have simplified and standardised map-making in the humanitarian world, making maps accessible to people who need it the most but do not per se have a GIS background. It will talk about how important it is that it is free and open-source software with a large, supportive community behind it.

The world's largest radio telescope in QGIS

The world's largest radio telescope, LOFAR, is based across Europe, with the core in the Northern Netherlands. It is operated by ASTRON, the Netherlands Institute for Radio Astronomy, in collaboration with other radio astronomy institutes. The telescope consists of about 50.000 antennas, spread over 50 stations (each around 100x150m), placed over various European country. The placement of the antennas must be precise to a few cm to be able to use them for radio interferometric imaging of the sky. The scale of this telescope, together with the strict accuracy requirements, make this telescope an interesting use case for GIS. I will show examples of the usage of QGIS in the processes of site selection, validation of antenna locations, as well as near-field imaging to find sources of radio interference.

Kart: Practical Data Versioning for rasters, vectors, tables, and point clouds; in QGIS

We’re drowning in data, but the geospatial world lags badly behind in versioning tools compared to our software counterparts. Kart (https://kartproject.org) is solving this with a practical open tool for versioning datasets, enabling you to work more efficiently and collaborate better. We will introduce you to Kart and demonstrate some of the key features, including our QGIS plugin. Kart allows you to quickly and easily manage history, branches, data schemas, and synchronisation for large & small datasets between different working copy formats, operating systems, and software ecosystems. Modern version control unlocks efficient collaboration, both within teams and across organisations meaning everyone stays on the same page, you can review and trace changes easily: ultimately using your time more efficiently.

Development of GIS Location finder module for Urban Upgrading Areas in Egypt

The Participatory Infrastructure Project (PIP) is a development measure implemented by the Ministry of Housing, Utilities and Urban Communities and the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) in Egypt. The objective of the PIP is to contribute to the socio-economic development in the informal areas of the Greater Cairo Region. GFA is contributing to the digitalization component of the project, by developing a GIS for the identification and mapping of Urban Upgrading Areas (UUAs). Services include the definition of suitable indicators and measuring techniques for the UUAs identification criteria and the development of the system. Furthermore, GFA provides expertise and advise on the existing data infrastructure, efficient data management and assists in data acquisition. Capacity development of the technical staff is in the centre of the assignment.

Pandapower QGIS Plugin

The pandapower QGis plugin enables importing and exporting pandapower and pandapipes networks into and from QGis. This allows user to create, modify and repair geo coordinates, substation and line data in pandapower/pandapipes networks. Fraunhofer IEE develops the plugin in the context of the project NRL, and it already helped repairing grid data according to OpenStreetMap data. In the final version, a user will be able to run grid calculations directly in QGIS and visualize the results.

Five cartographic feats for which I used to use Illustrator

In this workshop, a typical local mapping project (you know, one where cartographers always use Illustrator for) is being done using only standard QGIS visualization tools.

QGIS in Art and Design, a journey towards 3D hardwood maps

What is it in maps that fascinates people? A drive to understand the world around them, the nostalgic feelings of recognition or is it fuel for our adventurous and curious minds? We will take you along on our efforts to understand these drives and how it has led to making the worlds most detailed hardwood map art. QGIS has played an instrumental role in this journey of our company MAPLAB. During the session we will give insights in how we make our art and which specific role QGIS plays in this process. Naturally we will do this by bringing a small collection of our 3D Hardwood maps. You can expect to see Neighborhoods of Amsterdam, Munich and Hamburg detailed to the last canal house. We are looking forward to meet you and learn a lot from one another.
