GeoDMA is a toolbox for integrating remote sensing imagery analysis methods with data mining techniques producing a user-centered, extensible, rich computational environment for information extraction and knowledge discovery over large geographic databases.

It is easy and straightforward. After downloading/installing TerraView 5 in your computer, follow the instructions of this 35 seconds video:

The toolbox integrates the following techniques:

• image segmentation
• feature extraction and selection
• classification
• landscape-based metrics
• multi-temporal methods for change detection
• spatial data mining with decision-tree based strategies
• simulation methods to accuracy assessment

GeoDMA is developed in C++ under the Free and Open Source Software (FOSS) foundation, and works as a plugin for TerraView GIS.

GeoDMA has already been used to classify deforestation dynamics in Brazilian Amazonia.

GeoDMA works also with high spatial resolution urban imagery.

The system's workflow is the following:

• Thales Sehn Körting, project manager
• Leila Maria Garcia Fonseca
• Emiliano Ferreira Castejon

GeoDMA is free software, developed using TerraLib library. It works as a plugin for TerraView, also free software. If you want to download the source code of GeoDMA, try the following:

• Download TerraLib 4, TerraView and GeoDMA sources using SVN

  <https://svn.dpi.inpe.br/terralib/trunk/>

• Use Cmake to create your building files (Windows or Linux)

/path/to/terralib/trunk/build/cmake/

We are currently using Microsoft Visual Studio 2010 with QT 3.2 to compile GeoDMA in Windows, and gcc to compile in Linux. More information about compilation issues, please visit http://www.terralib.org/.
