This open course bridges GIS and data science with practical labs in R and Python.

Topics span vector and raster data, spatial weights, ESDA, clustering, and networks.

Introduction, Degrees and Radians, Tangents, Chords and Arcs, The Circle Theorems, Cyclic Polygons, Spheres, Cones and Cylinders, Conic Sections

Welcome to Fastreach Fastreach determines the reachable area of public transport given a start station, date and maximum travel duration (isochrone). These parameters can be configured on the panel in the top-left. The travel duration is capped at 120 minutes.

Between stations Fastreach considers walking as well as trains, trams and busses according to their timetables. The reachable area is visualized via a multi-polygon. It’s properties are described in the top-right panel.

Fastreach uses the weekly timetable data provided by Delfi e.V. from the 15 September 2025. Accordingly, timetables can only be considered complete from 15 September to 21 September. Data for walkways is taken from OpenStreetMap. Fastreach’s source code lives on GitHub.

Python implementation of R package gridmappr for automated gridmap layout generation. Pygridmappr automates the generation of small multiple gridmap layouts. Given a set of geographic point locations, it creates a grid with specified row and column dimensions, placing each point in a grid cell such that the distance between points in geographic space and grid space is minimized.

This implementation maintains full feature parity with the original R package and replicates the mathematical logic as faithfully as possible.

WALKER DATA is a data science consultancy specializing in geospatial and demographic data support for your business.

Launched in June 2024, JupyterGIS was introduced as a collaborative, web-based GIS environment built on the JupyterLab framework. Its objective is to

JupyterGIS - Collaborative GIS editor in Jupyter.

Features - Collaborative GIS Environment: Work together on geographic data projects in real-time.

QGIS File Support: Load, visualize, and manipulate QGIS project files (.qgs, .qgz), and other GIS data formats.

Interactive Maps: Render interactive maps and geospatial visualizations within Jupyter notebooks using the JupyterGIS Python API.

This demo runs a JupyterLab instance entirely in your browser with WebAssembly! 🤯

A Python package for creating interactive maps with anywidget and JavaScript mapping libraries - opengeos/anymap

MapMatrix - A React application for synchronized multi-view map comparison. Mostly generated by AI. - veloplanner/map-matrix

Access 15 terapixels of Prague’s detailed imagery for your research, for computer vision, photogrammetry, point cloud generation, 3D modeling and more! The Mosaic RealMap project utilizes 1.26 million high-resolution images to provide an unprecedented, detailed street-level map of Prague, aimed at supporting urban planning and data analysis.

Mapa a la carta le permite crear un mapa o foto aérea a su medida usando el Mapa Topográfico Nacional a escalas 1:25.000 y 1:50.000 o la fotografía aérea más actual disponible en el Plan Nacional de Ortofotografía Aérea.

A series of geospatial tutorials in the form of self-contained notebooks with step-by-step explanations and datasets. Features topics such as: GeoPandas, XArray, Dask, XEE (XArray + Google Earth Engine), Segment Geospatial, Web APIs.

Detects and saves GIS services from browsed websites instead of having to manually dig through network requests to find them. Features:

• Supports WMS, WMTS, WFS, ESRI and tile services.
• Normalizes URLs for use in ArcGIS, QGIS, and other GIS applications.
• Organizes services with custom folders and notes.
• Searches and filters collected services.
• Disables service detection on selected url’s.
• Exports service information for team sharing.

S2 is a library for spherical geometry written primarily by Eric Veach:

• Designed to have good performance on large geographic datasets.
• Organized as a toolkit with various layers, that gives clients as much control as possible.
• Works exclusively with spherical projections.
• API available in C++, Go, Java and Python.
• Supports Linux and MacOSX.

A5 is a geospatial index that partitions the world into pentagonal cells. The cells are available at 32 different resolution levels, with the largest cell covering the whole world, and the smallest less than 30mm². Within each resolution level the cells have equal area, to within 2%. A5 cells provide simple way to represent spatial data as a collection of cells, which together represent regions on the globe.

Official WFS and WMS services for the city of Warsaw, containing a variety of data.

Official Python command-line tool of the Overture Maps Foundation. Overture Maps provides free and open geospatial map data, from many different sources and normalized to a common schema. This tool helps to download Overture data within a region of interest and converts it to a few different file formats.
