GDAL

Documentation Build Status

GDAL is a translator and processing library for various raster and vector geospatial data formats.

This crate provides safe, idiomatic Rust bindings for GDAL.

Capabilities

GDAL is an incredibly powerful library. For a general understanding of its capabilities, a good place to get started is the GDAL User-oriented documentation. These features include:

  • Opening raster and vector file formats for reading/writing
  • Translating between file formats
  • Reading and writing metadata in raster and vector datasets
  • Accessing raster bands and their metadata
  • Reading and writing geospatial coordinate system and projection values
  • Warping (resampling and re-projecting) between coordinate systems

Documentation

This crate's API documentation is hosted on docs.rs.

The Rust documentation is currently a work in progress, and may not cover requisite details on parameter semantics, value interpretation, etc. Therefore, the authoritative documentation is that of GDAL in the form of its C and C++ APIs. The former is technically what this crate calls, but the latter is usually more clear and better documented.

Usage

This crate provides high-level, idiomatic Rust bindings for GDAL. To do that, it uses gdal-sys internally, a low-level interface to the GDAL C library, which is generated using bindgen. Using the gdal-sys crate directly is normally not needed, but it can be useful in order to call APIs that have not yet been exposed in gdal.

Version support

As a general rule, only GDAL versions in Ubuntu LTS-1 (previous LTS version, that is, GDAL 3.4 in 22.04 at this moment) are supported. gdal-sys might support earlier versions using the bindgen feature flag, but gdal does not.

Building this crate assumes a compatible version of GDAL is installed with the corresponding header files and shared libraries. This repository includes pre-generated bindings for GDAL 3.4 through 3.10 (see the gdal-sys/prebuilt-bindings directory). If you're compiling against another version of GDAL, you can enable the bindgen feature flag to have the bindings generated on the fly.
