GeoTools is a free software (LGPL) GIS toolkit for developing standards compliant solutions.

GeoTools is a contributor to the GeoAPI project - a vendor-neutral set of Java interfaces derived from OGC specifications - and implements a subset of those.

GeoTools 1 was built using the Java 1.1 environment to enable the execution of applets on a wide range of clients without the need for a plugin.

The code base has been fundamentally redesigned to take advantage of the latest Java platform and to follow OGC specifications.

The original version of this software dates back to the late 1980s, and was sold by its parent company AOA Geophysics to Fugro Geoconsulting Inc. in 2011.
