TerraHS

What is it ?

We have developed TerraHS, a software component that enables the development of geographical applications in a functional language, using the data handling capabilities of TerraLib. TerraLib is a C++ library that supports different spatial database management systems, and that includes a large number of spatial algorithms. As a result, we get a combination of the good features of both programming paradigms.

Download and Installation

Software dependencies

TerraHS is a Haskell GIS application built using the TerraLib GIS library. In below, is available some binaries packages for TerraLib and TerraView.

• [link]

The source files to TerraLib and TerraView can be downloaded from official sites:

• TerraLib
• TerraView.

We have developed some specific libraries to support some functionalities for TerraHS. The libraries can be installed from an unique package (TerraLib4c+Translib)

• [link]

Or can be download in separated way:

Translib, a library for translation among different geographic format files (no database connection), based in the TerraLib library. This library is required for TerraHS to deal whith shape files (*.shp).

• Ubuntu 9.04 (x86)
• Source, generic Linux

Terralib4c, a library that maps c++ Terralib functions and classes to C functions. Required by Haskell to do binding with TerraLib api.

• Ubuntu 9.04 (x86)
• Source, generic Linux
