TCLT (TerraLib Command Line Tools)
About
A set of TerraLib based command line tools to perform automated raster/vector/tabular data processing.
Main features:
- Itś a Free Sofware !
- No programming languages knowledge required !
- Support for command line based execution of one operation.
- Support for script/project based execution (allows the creation of complex graph-based chains of execution using a multi-threaded environment).
- Support for directory recursive processing.
- Support to handle and process large remote sensing data sets.
- Raster and vector data processing.
- Support for multiple processing cores (multi-threading).
- Support for all TerraLib/GDAL data set formats.
