Open Source Python Mapping Software

GeographicLib is a small C++ library for: geodesic and rhumb line calculations; conversions between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates; gravity (e.g., EGM2008) and geomagnetic field (e.g., WMM2020) calculations.

Seeker is an open source project that demonstrates how to obtain precise location information from devices using social engineering and web-based techniques. The tool sets up a phishing page that asks for location permissions, allowing GPS and other device data to be shared if the user consents. It can capture latitude, longitude, accuracy, altitude, direction, and even speed, with results displayed in a terminal. The project supports both manual deployment and tunneling services like Ngrok for external access. While primarily intended as an educational resource on security awareness, it highlights the risks of exposing geolocation data online. Its simplicity and effectiveness have made it a popular project in cybersecurity learning circles.

folium builds on the data wrangling strengths of the Python ecosystem and the mapping strengths of the leaflet.js library. Manipulate your data in Python, then visualize it in on a Leaflet map via folium. folium makes it easy to visualize data that’s been manipulated in Python on an interactive leaflet map. It enables both the binding of data to a map for choropleth visualizations as well as passing rich vector/raster/HTML visualizations as markers on the map. The library has a number of built-in tilesets from OpenStreetMap, Mapbox, and Stamen, and supports custom tilesets with Mapbox or Cloudmade API keys. folium supports both Image, Video, GeoJSON and TopoJSON overlays. To create a base map, simply pass your starting coordinates to Folium. To display it in a Jupyter notebook, simply ask for the object representation. The default tiles are set to OpenStreetMap, but Stamen Terrain, Stamen Toner, Mapbox Bright, and Mapbox Control Room, and many others tiles are built in.

To use precompiled wheels: 1) go to releases (Files) and download tarball needed; 2) install it with command: python3 -m pip install /path/to/wheel.whl Or simply use URL in pip: python3 -m pip install https://sourceforge.net/projects/gdal-wheels-for-linux/files/GDAL-3.1.4-cp37-cp37m-manylinux_2_5_x86_64.manylinux1_x86_64.whl/download URL may be found under "View details" button (i) To use GDAL in C/C++ project you need to link gdal lib AND all libs located at dir GDAL.libs (usually this folder resides inside python site-packages) To compile your own wheels see information given at forefather project: https://github.com/youngpm/gdalmanylinux Usually this is done via command `make wheels` GDAL wheels for Windows are provided by Christoph Gohlke at https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal Built with PROJ (proj.db is included), GEOS, EXPAT. See Dockerfile.wheels for additional components.

AVPython embeds the Python programming language within ArcView GIS 3.x. This project will also encompass efforts to build a similar bridge between Python and ArcObjects. An integrated, redistributable Python / PyWin32 setup wizard is also published here.

Warning: I found an error if the DR position is on the southern hemisphere. The PUB249 pdf files did not show this error and are correct (as far as I checked). All Revisions 8+ and the Windows release have been fixed. This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18). Also, you can create a PDF file that generates Pub 249 Vol 1 for any epoch you specify. The PUB249 as PDF is found under "Files". I wrote this for my aircraft bubble octant :-) It is mainly useful for air navigation as it assumes a bubble sextant but may be used for normal sextants as well. Requires Ephem and ReportLab (optional for PDF output) Not to be used for real-world navigation!

AIS Logger is a simple viewer and logger for data received by AIS-transponders or -receivers.

maptoposter is a code-driven poster generator that turns any city into a minimalist, print-style map artwork with consistent typography and themed color palettes. It is built around a simple command-line flow where you pass a city and country, and the tool fetches the relevant map geometry and renders it into a clean composition that looks like a design product rather than a raw GIS export. The repository includes a library of predefined themes that change the overall look (for example, blueprint-like styling, warm neutrals, or high-contrast variants), making it easy to produce multiple aesthetic directions without rewriting code. It is structured as a reproducible Python project with a clear install story and an emphasis on “run it once and get a finished poster” ergonomics. The output is designed to be visually striking and consistent across cities, which is useful for gifting, decor, or generating a catalog of posters programmatically.

GpxBase - simple GPS data manipulation Copy/Move/Delete/Update Waypoints/Tracks/Routes within a list of GPX/KML files. Open source solution to keep track of personal GEO Data Base from different sources (GPS devices, Google software and other).

OpenFreeMap is a free and open-source map hosting platform that allows developers to display customizable maps in websites and applications without relying on commercial providers. It uses OpenStreetMap data and modern vector tile technologies to deliver high-quality maps with flexible styling options. The platform can be self-hosted or accessed through a public instance, offering full control or convenience depending on user needs. It removes common barriers such as API keys, usage limits, and tracking mechanisms, emphasizing privacy and accessibility. The system is designed for production use, with automated tile generation, load balancing, and scalable hosting architecture. It integrates with libraries like MapLibre and Leaflet for easy implementation. Overall, OpenFreeMap democratizes map hosting by making it free, open, and developer-friendly.

PAGC is a command line and web service C library for performing postal address geocoding. A postal address geocoder takes a sufficiently detailed postal addresses and produces a digital map that displays the spatial location of those addresses.

PyOGCLib is a package of classes that implement specifications of the Open GIS Consortium (OGC), allowing Python applications to spatially plug-and-play with other geoprocessing systems.

A python API for Google's KML file. Added doc Added description to PlaceMark

ZMapServer is a Zope Product that provides a clean interface to the MapServer (http://mapserver.gis.umn.edu) web mapping application.

Scala and polyglot Spark library (Scala, PySpark, SparkSQL, ... ) focused on reading OpenStreetMap Pbf files.
