Very brief introduction to the huge geospatial universe. On this talk, we will cover most of OSGeo software and sibling initiatives to prove that Free and Open Source Solutions is not only a complete stack but the canonical solution when we want to have the best option possible.

Due to the growing population in urban areas, the building structures become more huge and complicated. The demands for geospatial information and services in indoor space are increasing as well as outdoor spaces. An OGC standard, called IndoorGML, was published to provide a standard indoor spatial model and exchange data format. And inous R&D initiative has been established to set up an eco-syste...

MapMint is a comprehensive task manager for publishing web mapping applications. It is a robust open source geospatial platform allowing the user to organize, edit, process and publish spatial data to the Internet. MapMint includes a complete administration tool for MapServer and simple user interfaces to create mapfiles visually. MapMint is based on the extensive use of OGC standards and automate...

It is a common thing when pattern analysis cases are just about visualizing the features. The talk would start with a gentle introduction into pattern analysis algorithms. I would focus on the benefits of using analysis in comparison to visualizing methods, present cases and show pitfalls in usage and implementing these algorithms.

Image classification of urbanization processes require reference data either for training or for validation. However, there is scarcity of reference labeled datasets specifically to detect urban areas. In this talk, I will present three approaches for collection of open-source reference data that mark built-up areas. None about this event: https://talks.2019.foss4g.org/bucharest/talk/GBJW3P/

There were no slides recorded due to a system failure. We are sorry for that! Understanding and predicting the distribution of life on Earth represent major research tasks in the face of global environmental change. These tasks often require the integration and analysis of big and diverse datasets that reflect properties of wild organisms and their abiotic environment across space. I will demonstr...

Land cover (LC) (and land use (LU)) maps are an essential components for regional decision-making. They inform policy-makers about the structure of their territory and frame policies including spatial and urban planning, environmental management, transport optimization, risk assessment, etc. The LC data currently available in the Walloon region in Belgium date back over a decade and an update was...

As the United Nations (UN) is a complex organization carrying out divers tasks in the world, most functions for an enterprise GIS are required. In order to support the requirements from the UN, the UN Open GIS Initiative was founded in 2016 with goals to provide GIS solutions for the UN based on open source software. The working group 3 of the initiative, named Spiral 3, aims to develop and delive...

Ships have long been required to carry nautical charts and nautical publications to plan and display the ship's route for the intended voyage and to plot and monitor positions throughout the voyage. Today we have complex electronical navigational charts and many of them are freely distributed and are constantly updated. An electronic navigational chart or ENC (IENC for Inland waterways) is an offi...

Planet with the help of GAF AG has established an adapter system that bridges the gap between Planets Advanced EO Imaging Platform and the Copernicus Space Component Data Access (CSCDA) Data Warehouse (DWH) project. For contributing to the ESA-CSDA, required interfaces to the ESA Coordinated Data Access System (CDS) and the Copernicus Service Projects (CSPs) have to be provided. We decided to impl...

In this paper, we address the course of dimensionality and scalability issues while managing vast volumes of multidimensional raster data in the renewable energy modeling process in an appropriate spatial and temporal context. Tensor representation provides a convenient way to capture inter-dependencies along multiple dimensions. In this direction, we propose a sophisticated approach of handling l...

With the LiDAR developments, point cloud is becoming a valuable resource to build 3D models of Digital Twins, the virtual representation of a real world physical feature (object or system). Even though 3D point cloud can be more suitable to depict the real world, it requires HPC. 3D model representations help applications to quickly handle and navigate data comparing to point cloud. However, the 3...

Browser capabilities have exploded in the past years and with it the possibilities to run large applications without the need of additional software. Still when combining interaction and visualization of larger datasets the number of nodes such as with SVG becomes quite difficult to handle (limited resources). That is why we have been experimenting with solutions to make use of WebGL, mixing rende...

In GIS software development there is often a need to seamlessly integrate a simple or more complex GIS solutions into new or existing non-GIS applications. Depending on the non-GIS system, number of different integration technologies are used. From communication standpoint there is a client-side integration based on WebSocket technology, JS API or using more recent technologies like custom element...

MapServer 7.4 was released earlier this year. The main focus of this release is MapScript - MapServer’s scripting language, and we'll review the various language options available along with other changes and lesser known features from recent releases. A summary of development from the recent OSGeo codesprint in Minnesota, and the road map towards MapServer 8 will be presented. A description of Ma...

A recent fun blog post turned into an idea for synthesizing imagery training data for ML applications. In the post we presented a method for identifying sasquatch using cloud native geospatial methods and tools. This talk will describe the cloud native approach we took and the opensource tools that were used. We will then describe and demonstrate an idea to create synthetic satellite imagery train...

2018 saw the release of [Julia](https://julialang.org/) 1.0, a high-level, high-productivity programming language, with the performance of a low-level language like C. That means looping over all features or cells and applying your own functions is encouraged. The [JuliaGeo](http://juliageo.org/) organization was first started in 2015 to provide support for working with geospatial data in the Juli...

The UN Open GIS Initiative is catalyzing the development of an open community for basemap vector tile providers. The Initiative promotes the UN Vector Tile Toolkit, a package of open source tools designed to enable public basemap providers, such as the United Nations geospatial information services or governmental mapping organizations, among others, to deliver their basemap vector tiles leveragin...

During the last decades, production of Land Cover maps (LC) at a continental and global scale has increased thanks to the progress in Earth Observation capacities, as well as due to high demand for these maps for many applications (e.g. climate change monitoring). However, the usefulness of these maps strongly depends on their accuracy. Therefore, for a fruitful LC maps exploitation, accuracy asse...

Natural Language Processing, has been revivified by Deep Learning approaches. This presentation will show what we already can achieve to convert plain Text to Map. Think for instance, to retrieving geometries conveys by an article, a book or a Tweet. None about this event: https://talks.2019.foss4g.org/bucharest/talk/PTX3JW/

[Gisquick](http://gisquick.org) is an open source geospatial data publishing platform. We have developed it for rapid sharing of our projects created with QGIS. We put together minimal set of functions for useful generic web mapping application - a web client for QGIS projects. With Gisquick, you can share GIS outputs with others easily and much quicker. It consists of QGIS plugin, Django based se...

Not all open data comes in traditional geospatial formats: for years, organizations around the world have collected photo and video logs of roads for annual surveys, but until recently these have been overlooked as a form of open data. Mapillary now hosts over 500,000km of government road imagery. We will explore how this is being used both to improve government workflows and how traffic signs, cr...
