What is GeoFastMapAPI?

GeoFastMapAPI is an open-source server designed to serve vector and raster map data quickly and efficiently. It's built for cartographers, GIS professionals, and developers who need to host and distribute geographic information without relying on commercial mapping platforms. The tool handles both vector data (points, lines, polygons) and raster data (satellite imagery, terrain models), making it suitable for a range of mapping applications. Being open-source, you can inspect the code, modify it to suit your needs, and deploy it on your own infrastructure, giving you full control over your geographic data and how it's served.

Key Features

Vector tile serving

efficiently delivers vector map data in standard formats to web and mobile clients

Raster tile serving

hosts and streams raster imagery and gridded data sets

Open-source codebase

full source code available for inspection, modification, and self-hosting

Fast performance

optimised for quick data delivery to reduce map load times

Standard format support

works with common GIS data formats and tile specifications

Self-hosted deployment

run the server on your own hardware or cloud infrastructure

Pros & Cons

Advantages

  • No licensing costs or vendor lock-in since it's open-source
  • Complete data privacy when self-hosted; your geographic data remains under your control
  • Can be customised and extended to match specific project requirements
  • Suitable for both small projects and large-scale geographic data distribution

Limitations

  • Requires technical knowledge to set up, configure, and maintain a server
  • You're responsible for infrastructure costs, security updates, and system administration
  • May lack some advanced features or integrations found in commercial mapping platforms

Use Cases

Running a private map server for a government agency or enterprise that needs data sovereignty

Serving geographic data for a custom web mapping application without commercial platform dependencies

Hosting historical or specialist map datasets for research or heritage organisations

Building a geospatial infrastructure for urban planning or environmental monitoring projects

Providing basemaps and data layers for embedded maps in applications where you control the backend
