Terralib vector data







TerraLib – Vector data

  • Some functions provided by TerraLib

    to deal with vector data:

    • Topological functions

      • Touches, Intersects, Inside, ...

    • Geographical operations

      • Buffer, Union, Intersection, ...

    • Spatial and temporal queries

    • Spatial and Temporal statistics

      • Moran, Kernel Map, ...

    • Address Geocoding

Terralib raster data

Image processing Application


TerraLib Kernel




TerraLib – Raster Data

  • TePDI – TerraLib image processing module:

    • Contains a set of functions to process raster data

Terralib raster data1

TerraLib – Raster Data

  • Current functions available in TePDI:

    • Image blending – Euclidian and multi-resolution blending.

    • Edge detection filters – Robers and Sobel filters.

    • Mask based linear filters.

    • Morphological filters ( Erosion, dilation and median ).

    • Radar filters ( Frost, Lee and Kuan ).

    • Image fusion ( HIS, Wavelets and Enhanced Wavelets algorithm )

    • Image Arithmetic algorithms.

    • Image contrast (linear methods, non-linear methods, statistical method ).

    • Image mosaic algorithms (Geographic and tie-points based).

    • Image registering algorithms.

    • Image segmentation algorithms.

    • Wavelets based decomposition filters.



  • PHP extension

  • Visualize and query geographical data from a TerraLib database in Web applications

  • Free and Open source

  • Example of application:

    • TerraWeb
