See that little map on the geoserver.org web site? While looking a lot like plain OpenStreetMap tiles, it’s actually rendered by a GeoServer, using CSS styles, off a PostGIS database. The map aims to be a very close clone of the actual OSM official one, meaning it has a lot of little details often removed from lookalikes to reduce the data to be loaded and rendered. This presentation will provide...

Having been around for two decades, QGIS clearly is an organically grown project. It has primarily been fulfilling the various special needs of its developers. From an outsider's perspective, it is an amazingly rich patchwork of features. However, some are deeply hidden in numerous layers of user interface elements, requiring intense training for getting used to. Others are only accessibly through...

Created to serve a locally-led global map making network, the original Open Green Map (OGM) - www.opengreenmap.org, a social mapping platform, was launched by Green Map System in 2009. In the decade since, an 8 language interface and mobile site collector are among the features that attracted users in 40 countries. Dubbed ‘open’ as sites could be enhanced by the public, more than 40,000 sites were...

The FOSS4G community is much more than OS Software. The community, while small globally, has had, and continues to have an outsized impact on science using geospatial data. This impact starts with Open Ideas: the community fosters the free-flow exchange of ideas that lead to Open Standards for interoperability, Open Data for democratizing data access, and Open Source Software for the use and analy...

Our seas and oceans are substantially polluted by conventional and chemical munitions from the two World Wars. They were introduced by different pathways e.g. mine laying, naval battles and shipwrecks. However, the biggest amount originates from large scale ammunition dumping activities after World War II. The goal of the OpenSource based Ammunition Cadastre Sea is therefore data acquisition, asse...

SHOGun is an Open Source WebGIS framework, that is widely used in private companies, public administrations and also research projects. SHOGun combines user-, data- and application management through a webfrontend, like many others do. Learning new workflows and familiarizing yourself with new application environments is a big challenge for many users. Therefore, possibilities should be created to...

The talk will present case architectural solutions behind a cloud platform for Asset Management. The platform manages geo-spatial information and provides analytics services and tools for critical assets and infrastructures monitoring, for customers and prospects worldwide. The huge amount of geo-spatial data to be managed required us to rely on a cloud-based distributed architecture, based on ope...

OpenMapTiles is an open-source set of tools for processing OpenStreetMap data into zoomable and web-compatible vector tiles, which are ready to use in OpenLayers, Mapbox GL, Leaflet, QGIS as well as mobile applications. This talk gives an overview of the major changes in the project. Apart from providing a base map of the whole world, the same principles of OpenMapTiles can also be used to create...

GEO 101 is a gentle introduction to all activities and developments of the Group on Earth Observations. The GEO Global Water Sustainability Initiative (GEOGLOWS) changes the paradigm for how streamflow information is created and disseminated. Traditionally, each water organization was required to have the expensive infrastructure and capacity to access large global datasets and develop their own m...

The Open Green Map app has been used by map makers around the world to collect thousands of green sites over the last decade. With a new implementation, the Open Green Map has potential to truly live up to its name, and achieve a sharable, scalable, fast and easy to use application. This is what the project I will present sets out to do. Working on an open source project can sometimes make it seem...

The availability of the growing volume of environmental data from the Sentinel satellites represents a unique opportunity for the operational usage of Earth Observation (EO) for wetland inventorying, assessment and monitoring on global scale. However, it also poses major challenges in terms of data access and exploitation to achieve its full potential. GlobWetland Africa (GWA) Toolbox is an outcom...

TEAM Engine is a testing facility enabling developers and users to test geo services, such as WFS or WFS, and geo formats, like GML or GeoPackage. The Open Geospatial Consortium (OGC) provides various test suites for TEAM Engine to support implementing and testing of GIS software basing on OGC standards. TEAM Engine is an OSGeo project in incubation phase. A test suite for new OGC standard WFS 3.0...

Tokyo Metropolis publishes a lot of data, and holds an application contest using that data every year. The 2017 contest had the challenge of "developing a tool that would allow everyone to find the perfect toilet for them on the go". I applied for the contest on this subject. There is a chat tool named LINE in Asia,many people use it. We can respond to user input programmatically by creating an au...

The talk will introduce Copernicus - the European flagship Earth Observation programme - its support for European policy, the Copernicus startup and research programmes, and its contribution to the European Data Economy. The talk will also discuss the challenges and opportunities related to the large volumes of data being generated. None about this event: https://talks.2019.foss4g.org/bucharest/ta...

The Copernicus Global Land Service (CGLS) aims to provide yearly-updated land cover maps, including land cover fractions (i.e. the fraction of each land cover class within each pixel). It makes use of FOSS software (Python, R, GDAL) for all data processing steps. Our work in the project focuses on two aspects: land cover fraction mapping at the continental level (Africa) and yearly map updating. F...

A common question seen on many open source mailing lists is “When will you guys fix my bug? It is critical to my company!” This is often followed by one of the developers replying to say “When you write a fix or pay someone to do it”. This leads to the user complaining to everyone that this “snarkiness” is not a “welcoming” response or how unreasonab...

QGIS 3D native rendering has been introduced since QGIS 3.0, thanks for the funding we received from QGIS.org. Over the past couple of years, we have added several features and enhancements. QGIS 3D can now render raster, vector and mesh layers. Depending on the data or geometry type, there are various method of visualising and styling the 3D data. In this talk, we will go through: - Supported 3D...
