TerraLib is an open-source geographic information system (GIS) software library. It extends object-relational database management systems (DBMS) to handle spatiotemporal data types.
Using TerraLib, the TerraView open-source GIS was developed, which provides functions for data conversion, visualization, exploratory spatial data analysis, spatial statistical modelling and spatial and non-spatial queries.
Another application is TerraAmazon, Brazil's national database for monitoring deforestation in the Amazon Rainforest. It handles more than 2 million complex polygons and 60 GB of remote sensing images.
