32Wulkiewicz, AdamWhat are spatial reference systems and how to convert between them? What are various ways of creating transformation representation in Boost.Geometry and how to use them to convert between polygons on the surface of a globe and flat surface of a map?
We discuss solutions to those questions highlighting some of the latest developments in Boost Geometry, the library that is currently being used to provide GIS support to MySQL. The implemented solutions allows to define transformations both in compile-time and run-time with known tradeoffs: execution time vs compilation time, run-time flexibility vs compile-time error reporting, etc. Last but not least we discuss similarities and differences between Boost.Geometry and Proj4 libraries.
The presentation is example driven thus emphasizing on the user perspective.

23Picavet, VincentThe GIS market evolves at a fast rate. OpenSource GIS solutions have a much stronger maturity now than a few years back.
We see a global trend with big companies modernizing their IT and their GIS solutions, seriously evaluating OpenSource GIS compared to their former proprietary softwares, and launching migration plans.
OpenSource solutions often come as independant components though, sometimes making it difficult to comprehend the best way to build a full-featured and coherent stack.
While we do not pretend to have the best solution for all, in this presentation we detail a proposal for a full GIS infrastructure. PostGIS and QGIS at are the core of this stack, and it covers a wide range of needs for end-users : desktop, web, mobile…

15Fenoy, GéraldMapMint 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 automates WMS, WFS, WMT-S, and
WPS. Most of the MapMint core functions are run through WPS requests which are calling general or
geospatial web services: vector and raster operations, mapfiles creation, spatial analysis and queries
and much more. MapMint server-side is built on top of ZOO-Project, MapServer and GDAL and its
numerous WPS services are written in C, Python and JavaScript. MapMint client-side is based on
OpenLayers and Jquery and provides user-friendly tools to create, publish and view maps.
MapMint architecture and main features will be introduced in this presentation, and its modules
(dashboard, distiller, manager, and publisher) will be described with an emphasis on the OGC standards and
OSGeo software they are using. Some short but relevant case studies and examples will finally
illustrate some of the key MapMint functionalities.

1Smith, MichaelPDAL is Point Data Abstraction Library. It is a C/C++ open source library and applications for translating and processing point cloud data. It is not limited to LiDAR data, although the focus and impetus for many of the tools in the library have their origins in LiDAR. PDAL allows you to compose operations on point clouds into pipelines of stages. These pipelines can be written in a declarative JSON syntax or constructed using the available API. This talk will focus on the current state of the PDAL Pointcloud processing library and related projects such as COPC and Entwine, for pointcloud processing. Coverage of the most common filters, readers and writers along with some general introduction on the library, coverage of processing models, language bindings and command line based batch processing. First part will be covering new features for current users. Some discussion of installation method including Docker, binaries from package repositories, and Conda packaging. For more info see pdal.io

9Pronk, MaartenMaarten Pronk is a GeoData Scientist at Deltares where he works on open-source software projects. These projects include: + Generating DTMs derived from large scale pointclouds in the Julia language using the latest research in order to calculate worldwide flood risks. + Writing Python based back-ends for generic web based interfaces to our numerical models running in Kubernetes workflows in the cloud, all provisioned with Ansible. He is an external PhD candidate at the TU Delft in the 3dgeoinfo research group where he also obtained his Master of Science in Geomatics. His thesis dealt with storing massive TINs in a spatial database. In his free time he tinkers with open data and open-source software.
During the 2023 OpenGeoHub Summer school, he granted OpenGeoHub’s communication experts an interview, shared his experience in the Julia language, and gave them his views on the topic of processing of geospatial data and its challenges.

62Bivand, RogerUntil June 2023, maintainers of legacy packages using rgdal, rgeos and/or maptools were encouraged to migrate to sf/stars or terra, as described in https://github.com/r-spatial/evolution and blogs listed there: https://r-spatial.org/r/2022/04/12/evolution.html, https://r-spatial.org/r/2022/12/14/evolution2.html, https://r-spatial.org/r/2023/04/10/evolution3.html.
In June 2023, sp switches from using rgdal by default for sp::CRS and sp::spTransform to using sf functionality by default.
From October 2023, retiring packages rgdal, rgeos and maptools will be archived on CRAN. This means that residual installations of retiring packages will continue for R 4.2 and R 4.3, but will not be updated after October 2023, nor will they be available for R 4.4.
The workshop presented current status, and may have assisted participants with affected workflows to adapt; the same applied to key affected packages needed in participants' workflows.
Participants were invited to contact the presenter with practical ideas to packages to adapt, and time may also have been used to prepare non-maintainer update candidates for non-responsive packages. The count of affected packages was over 800, but the severity of the impact of the withdrawal of the retiring packages varies by the dependency category, strong dependence as Depends or Imports, weak dependence as Suggests.

5Perkins, LukMy laptop environment is the staging ground for my life as a developer. In this talk, I’ll tell the story of how a Nix flake I call Nome, my “Nix home,” provides not just a fully declarative and easily reproducible global environment on my laptop but also a variety of templates and other helpers that have supercharged my per-project environments as well.
Years ago, I defined my laptop environment using a pretty standard janky jumble of dotfiles and shell scripts. Years after first encountering Nix, Home Manager gave me my first taste of using declarative logic to define my system, and I continue to tweak my Home Manager config every day. But now I’ve gone several steps further and created a Nix flake that I call Nome—my “Nix home”—which defines my global environment using Home Manager but also provides a set of NixOS configurations, flake templates, Nix-built scripts, Nix helper functions, Nix-defined Docker containers, and other goodies that have markedly improved my productivity and eliminated a whole class of paper cuts from my daily work life. In this talk, I want to provide a basic overview of Nome’s flake outputs and provide a brief demo of how I use it to get up and going in a new project.
Speaker: Luc Perkins

By directly reading the GeoTIFF file data and running all computations client-side in the browser, this library helps you easily put a GeoTIFF on a map without needing to run a server or write a lambda function. This talk will go over some short code examples and use cases. Familiarity with JavaScript is recommended but not required.

But what about Free Open Source for Geospatial software and data access and availability?

1Mori, ShigefumiIn my talk, I will recall my experiences since my student days.
There were several instances which drew my attention to algebraic geometry, and after all, I became an algebraic geometer. The first was a famous example of complete non-projective algebraic variety shown to me by Prof. H. Hironaka when I was a junior. One can see it in R. Hartshorne's book "Algebraic Geometry," but he wrote it a few years later during his stay in Kyoto. I will explain about a few more instances in my talk.
