GDAL is an MIT-licensed open source translator library that provides a unified abstract data model for reading and writing geospatial raster and vector data across hundreds of file formats. It serves as a foundational geospatial data translation library, enabling access to diverse geospatial data formats through a single, consistent interface. The library exposes its core functionality through command-line utilities that allow users to translate, convert, and process geospatial data between formats. A coordinate transformation engine handles conversions between spatial reference systems, whil

A map representation based on 3D segments

Mapbox GL JS is a WebGL map rendering engine and interactive web map framework used to render vector tiles, raster imagery, and 3D terrain in the browser. It functions as a vector tile map library and geospatial data visualization tool, employing GPU-accelerated shaders to transform geospatial data into interactive maps. The project distinguishes itself through the integration of custom WebGL layers directly into the rendering pipeline and the use of data-driven expressions to map feature properties to visual attributes. It supports specialized data loading via PMTiles and provides offline ma

iD is a web-based geographic information system tool and vector map editor designed for the OpenStreetMap collaborative database. It serves as a crowdsourced cartography interface for contributors to update global geographic infrastructure and land use data. The tool enables the modification of geographic shapes, attributes, and metadata directly within a web browser. It focuses on managing spatial data and physical landmarks by manipulating topological relationships between map nodes, ways, and relations. The project covers a broad range of capabilities including collaborative map editing,

Java map matching library for integrating the map into software and services with state-of-the-art online and offline map matching that can be used stand-alone and in the cloud.

A Blender add-on to import models from google maps

Mapnik is a cartographic rendering library and map rendering engine designed to convert geographic information system data into visual maps and printable layouts. It serves as a spatial data visualization tool that applies symbology and styling rules to diverse geographic data sources. The project utilizes an XML map configuration framework to define the visual appearance of maps, allowing the separation of styling logic and layout properties from the core rendering engine. Its capabilities cover geographic information visualization and cartographic style management. The system integrates sp

Plugins to make Autoware vector maps in Unity

GeoPandas is a Python library that extends pandas with native support for geospatial data. It treats geographic geometries—points, lines, and polygons—as a first-class column type within DataFrames, enabling users to store, manipulate, and analyze vector spatial data alongside traditional tabular attributes. The library is built on top of proven geospatial components: it uses Shapely for all geometric operations, Fiona and GDAL for reading and writing standard spatial file formats, PyProj for coordinate reprojection, and an R‑tree spatial index (from Shapely) to accelerate spatial queries.
