The impact of land use and land use change and forestry (LULUCF) on soil organic carbon (SOC) stocks and greenhouse gas (GHG) emissions is important for both national GHG inventory reporting and worldwide strategy to offset GHG emissions. Within the Irish Soil Organic carbon and Land Use Mapping (SOLUM) project, Eurostat’s Land Use/Cover Area frame Survey (LUCAS) of 2015, LUCAS soil survey of 2009...

With PyQGIS you can write scripts and plugins to implement new features and perform automated tasks within QGIS, let's see how we can do that more efficiently thanks to some nifty tricks. Thanks to tricks like using decorators and the qgis.utils module one can improve readability and performance by simplifying a lot of code None about this event: https://talks.2019.foss4g.org/bucharest/talk/QQWQQE...

With Foreign Data Wrappers (FDW) you can access remote objects from SQL databases. This feature is part of the SQL/MED (SQL Management of External Data) specification that was added to the SQL standard. With PostgreSQL you can make use of this great functionality. You can access different remote datasources via FDW for example an ORACLE or MySQL database, JSON- or CSV-file, sources via ODBC and ev...

FrontierSI have been working with the Open Data Cube Community to develop simpler ways of running the ODC, and one of these is the ‘Sandbox’ project, where we have built a pre-configured ODC instance as a reference deployment. The Sandbox aims to provide developers, data scientists, decision makers and everyone else a way to learn about remote sensing, the ODC generally, or about the various appli...

OSGeoIE was formed in 2015 and this year we held our 3rd annual conference. In our mission statement we aim to "create a networked community of OSGeo/FOSS4G users, developers, practitioners, teachers, advocates, etc in Ireland". Our talk will discuss experiences since 2015: Developing a shared understanding of community participation in OSGeoIE events, how to be effectively resourced as a local co...

If a company discovers GIS as a usefull tool, it normally starts with a few desktop GIS (most likely QGIS) users. Later on, if GIS is more widely used within the company, the need for a spatial data infrastructure (SDI) arises. This presentation shows how to step-by-step create a slim SDI around QGIS, which other software components can be used, their advantages and disadvantages and how they play...

Martin is a PostGIS vector tiles server written in rust. It is *Fast*. Getting vector tiles out to the web has never been easier. This will be a simple presentation showing how to get started using Martin and having your data being pushed to Leaflet, OpenLayers or Mapbox GL in under 20 minutes.

The European Flood Awareness Ssytem (EFAS) operates on a pan-European scale to provide coherent medium range flood forecasts and related informations and which serves as an independent reference information set for most of the hydrological services responsible for flood forecasting in Europe. EFAS was developed from the Joint Reaserch Centre (JRC) and the European Centre for medium range weather f...

Open Source design has a plethora of hurdles to leap before it could become fully adopted by the global design community. Exploitative ‘work for free attitudes’, workflows and how design functions/roles connect up through a product life cycle, how our software doesn’t yet allow for robust and collaborative versioning across different designers and how the open source community as a whole, is over...

Deltas are the most productive and economically important global ecosystems associated with some of the largest coastal marine fisheries and the majority of global wetlands. They also the most extensive coastal lowlands threatened by climate change and human activities such as agriculture, navigation, fisheries, forestry, fossil energy production and industrial urban development. Under climate- an...

Curricula in geography and GIS can be transformed by integrating open source GIS with critical human geography. This integration requires students to develop strong skills in assessing error and uncertainty and in questioning the powerful social implications of spatial information technologies, and requires faculty and students to develop new open curricula, features and algorithms to facilitate t...

QGIS - like Geoserver, Mapserver and all the great OSGEO project - do no longer need to prove they can do the job. We now have millions of users, with great expectations, growing budgets and growing communities. Still we lack funding for boring tasks : packaging, bugfixing, documentation, QA and marketing needs some love. **What about changing minds and stop saying open source does not cost anythi...

In the Czech republic and countries in the central-east European region, the market share of the open source software for geospatial is on very slowly ascending curve. We asked a question, what is the market missing, so that the acceptance of the FOSS4G software could be done in much faster way? We came into several conclusions: * Public administration does miss technical support * Both do need tr...

We would like to present how our small community of Geoinquiet@s Argentina works. Since 2012 we have been working hard in order to evangelize about free and open source software. Drawing inspiration, and a name, from the Geoinquietos Spain micro chapter a few people started gathering (beer in between) to spread the word about free tools for geomatics. Since then, we have been able to do four confe...

Vector tiles are an established format to publish highly interactive maps for use on mobile devices and desktop browsers. A benchmark compares MVT tile generation and tile serving performance of specialized servers like t-rex and proven map servers like UMN Mapserver.

It is widely known that China will soon be the leading player in world economy overtaking the traditional hubs of North America, Europe and South-East Asia. Its economic activities increasingly influence countries beyond its own borders and dominate global economic growth. The analysis of the shifting axis uses global trade data that countries report through the Harmonised Commodity Description an...

Vector tiles are a challenge for the creative mind. In this talk we will take you along the path of making artistic styles for your vector tiles like this [Crafty map](https://apps.webmapper.nl/crafty_map/) and the [Paradise in the Polder map](https://nieneb.github.io/mycelium/). Starting from the importance of having a good and clear tile set to making your own sprites and glyphs with command lin...

The SpatioTemporal Asset Catalog specification is an emerging standard for to cataloging geospatial data from different sources, and a specification for serving that data in an API. This talk will be a detailed overview of STAC illustrating it's usefullness in integration with cloud-based processing workflows. It will cover the core set of metadata fields for STAC Catalogs, Collections, and Items,...

For almost 5 decades, ECMWF, the European Centre for Medium-range Weather Forecast, has been producing numerical weather forecasts and maintained one of the largest archives of meteorological data. Recently the European Commission has entrusted ECMWF with the implementation of the Copernicus Climate Change Service (C3S), and Atmosphere Monitoring Service (CAMS), opening up the access to a huge amo...

The road traveled to get to a consistent, accurate and fast national vector tile set: Over the past two years we've been testing various open source tools to create and maintain [cartiqo](https://cartiqo.nl): a vector tile set for the Netherlands aimed at creating beautiful webmaps. In this talk we discuss these various tools and explain why we went with **[Tegola](https://tegola.io/)**. Building...

MySQL 8.0 was a huge step in terms of spatial support -- a step up from flat Cartesian coordinate systems to ellipsoidal geography. In this talk we'll go on a quick tour of the spatial support in MySQL. We'll cover data types, functions, indexes, coordinate reference systems and other core topics. We'll look at both the big design decisions and practical use. What can MySQL do? How does it work? W...
