geos
Map server to view, measure and print maps in a web browserand to display maps as an overlay in google earth.
Decision gist · record as of 2026-08-14
No. The project is abandoned, with no releases or commits since 2021 and an archived repository. Dependency compatibility with modern versions of flask, lxml, and pillow is uncertain. The author explicitly recommends alternatives: kmlsuperoverlay for overlay generation, QGIS for local map work, or MapProxy for server deployments. Use only if you have legacy code already depending on it or are willing to fork and maintain it yourself.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires flask, lxml, and pillow to be installed; Python version support is unspecified in the package metadata.
- Installation is straightforward, but the project is abandoned as of 2021 with no active maintenance.
- The repository is archived and the author has moved to other tools.

What it is and what it does
GEOS is a Python web server that generates and serves tiled map overlays for Google Earth, alongside a browser-based interface for viewing maps, measuring distances, and generating print-ready PDFs. It was designed to provide a unified interface for map conversion, display, and offline preparation, similar in spirit to tools like MOBAC but with web-based access.
The package includes both a server component (built on Flask) and a library interface for programmatic coordinate conversion and map printing. However, the project is no longer maintained—the author explicitly states it is abandoned and recommends users migrate to QGIS for local map management or consider kmlsuperoverlay as a maintained PHP alternative for overlay generation.
Use it for
- Generate KML overlays of tiled maps for viewing in Google Earth without writing custom code.
- Measure distances and areas on maps through a web browser interface without installing desktop GIS software.
- Export maps as high-quality PDFs for printing from a web application.
- Programmatically convert map coordinates or access map printing functionality from Python code.

Installation is straightforward, but the project is abandoned as of 2021 with no active maintenance. The repository is archived and the author has moved to other tools. Low install friction from dependencies alone does not offset the lack of ongoing support.
