Working Group 4, also called Spiral 4, of the UN Open GIS Initiative aims to provide solutions to collect geospatial data for UN missions. Due to the diversity and complexity of source data and mission fields, one single solution for geospatial data collection could not satisfy the requirements from the UN. Furthermore, most of the UN missions take place in regions where geospatial data are very l...

To be INSPIRE compliant is a requirement implied by the European Union. From an administrative view, the desire for standardized data for aggregation is very comprehensible. Producing and delivering data that complies with these requirements comes with a great set of challenges but is key to bring any such system to success. In Switzerland the same requirements exist for standardization and aggreg...

OSM has long since established itself as the leading global street database. Interactive multi-resolution 3D-globe-streaming technology has been around for quite some time. Yet little effort has been made so far to create a global OSM-based 3D street map. In this talk we will show how OSM, vector tiles and VTS Geospatial can work together to create a global 3D street map based purely on open data...

The last few months have been quite a ride for our good ol’ web mapping companion. What should have been a peaceful rest after a lengthy refactoring in version 5 did in fact end up being an involved rewrite of its rendering code: better **performance**, nicer **vector tiles**, smoother **WebGL**, more options and even some Mapbox goodness in there. In this talk we will take a quick tour of all the...

Audio is unfortunately missing from the first 5 minutes. Taking advantage of the emergence of Open Data platforms dedicated to urban services, one can try to understand the functioning of cities. The biggest challenge is no more to get the data; but to structure it, analyze it, extract new information from it, and design clever representations in order to visualize it. This presentation will focus...

In this talk, we will give an overview of the recent works that have occurred in the PROJ, libgeotiff and GDAL libraries regarding Coordinate Reference Systems (CRS). Those improvements have mostly taken place in the venerable PROJ library that has evolved over the last 30 years from handling “only” more than hundred of cartographic projections to becoming a full-fledged library for CRS management...

The climate change and the recent extreme events occurred all over the world draw again the attention to the natural hazards both for prevention and for management aspects. In this context, environmental modelling can help in mapping hazards and risks zones and to support decision makers in building functional infrastructures with low environment impact and for a safe urban planning. In the last d...

Geographic flow visualization (gFlowiz) is an interdisciplinary project dedicated to flows and networks in the geoweb. It is led by a team of French researchers and engineers in Geography, Cartography and Computer Science from both IFSTTAR and CNRS. gFlowiz follows the new paradigm of « visualization mapping » (MacEachren, 2004) not present in current geoweb applications. All types of flows, movem...

You may have heard about the GeoCat Bridge plugin for ArcMAP. A plugin to facilitate hybrid open source/proprietary environments. We’re planning a similar tool for QGIS. We'll present the current status and challenges in this presentation. Main goal of this plugin is to ‘facilitate publication to an open OGC/INSPIRE SDI as easy as possible’. To facilitate this we apply various principles: - Publis...

The INSPIRE Reference Validator is the tool adopted by EU Member States to validate the resources of their Spatial Data Infrastructures. It is an implementation of the ETF, an open source testing framework based on ISO and OGC standards, which performs tests organized into Executable Test Suites (ETS) using SoapUI, BaseX and TEAM Engine. The ETF can be used via either a web application or a REST A...

GeoStyler is a react-based Open Source UI library for creating style editors for WebGIS applications. Cartographic styling of geodata on the web has been a recurring topic in the geoinformatics world. There are various standards - official standards as well as industry standards and project-related styling rules. However, we think that an interactive web-based software is the best solution to enab...

Deutsche Telekom AG (DTAG) revolutionises the planning process of fibre networks in order to increase the number of connected households and industries dramatically as well as to shorten the time to market in general. A brand-new world comprising the build up of a major SDI, lots of geodata and heavy geoprocessing is needed to substitute previous manual tasks and to sustain the goals. Think about...

In order to increase interoperability and facilitate the reusing of geospatial data, it is proposed a methodology of publishing INSPIRE-compliant datasets as Linked Data, using the RDF format and various ontologies such as the ones derived from the ARE3NA for the Annex I themes, or GeoSPARQL from the OGC. This methodology would cover the whole process of generating the RDF triples from GML sources...

The W3C Maps for HTML Community Group is working to define a (new) "map" HTML element that would be used to define map contents in a web page and would be directly supported and rendered by web browsers in a standardized way. All this is done by building on existing standards such as WMS, WFS and Tile Services. In addition to standardizing the encoding and access to map elements in web browsers, t...
