===== TerraLib and TerraView =====


TerraLib is a open source GIS software library to support the development of customized geographical applications.

After several improvements the TerraLib Project Team is launching **TerraLib 5.7.0**. Together with the TerraLib 5.7.0 we also launching **GIS TerraView 5.7.0 **.

In 2015, the TerraLib team launched a completely reengineered version of TerraLib and TerraView ((we adopt a semantic versioning system where each version number has a format Major.Minor.Patch. Bug fixes not affecting the public API increment the patch version, backwards compatible API additions/changes increment the minor version, and backwards incompatible API changes increment the major version)) under the LTS terms ((The LTS term is applicable to open-source-projects designed to be supported for a long than normal period - in our case two years)). Some information about this process can also be found here just to document the evolution.

Both TerraView and TerraLib are free and open source under the [[http://www.gnu.org/licenses/lgpl.html|GNU Lesser General Public License (LGPL)]]. Both are developed by the [[http://www.inpe.br|National Institute for Space Research (INPE)]], Brazil.

Binaries (executables) of TerraView, built for different platforms, can be downloaded from [[wiki:downloads#terraview|here]].

To download the source code, build and install TerraLib and TerraView follow the instructions in the [[wiki:documentation:devguide#downloading_the_source_code_and_building_instructions| developer´s guide page]].

 
For more information see the [[wiki:documentation|documentation page]].

 
**IMPORTANT NOTE:**

The TerraView 5.y.z has been built on top of the TerraLib 5.y.z. TerraLib Major version 5 presents new concepts (such as Project) that were not available in the previous major versions. It also presents new or enhanced versions of functions for data conversion and data exchanging; access to different data sources; map display; explanatory spatial data analysis; spatial and non-spatial queries; vector and raster processing and spatio-temporal analysis functionalities; drag and drop layers directly to Layer Explorer among others.

These changes are reflected in TerraView 5.y.z interfaces.
 
Backwards compatibility is from 5.5.2 release. However it is easy to create a project with the same layers of an old project using the drag and drop functionality. 

We would like to have feedbacks from users of the new **TerraView** in order to keep releasing improvements.
 
Any feedbacks should be sent to terralib-community@dpi.inpe.br.

The previous releases, including the ones under **4.2.z version** can be accessed at [[http://www.dpi.inpe.br/terralib5/wiki/doku.php?id=wiki:downloads:previous_releases|download page]].
