TerraLib
software
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.
Design and development
The library supports different DBMS, including MySQL, PostgreSQL, and Oracle. Its vector data model is upwards compliant with Open Geospatial Consortium (OGC) standards. TerraLib supports the development of geographical applications using spatial databases.
The design goal for TerraLib is to support large-scale applications using socioeconomic and environmental data. It handles spatiotemporal data types (events, moving objects, cell spaces, modifiable objects) and allows spatial, temporal and attribute queries on the database.
The public source identifies “TerraLib” as software. This brief keeps that definition visible, then builds a research path around TerraLib and software.
Why this record matters
A short description can identify a subject without explaining its stakes. For “TerraLib”, the useful work is to connect “software” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 8, 2026. The linked authority identifier is Q7703039. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
