  2. J Jfddfjh gfsdfgdfssf fsdf fsdfsd sdfsdf TerraLib DBMS What is TerraLib? • Free and Open source GIS software library • GNU Library License • Provides support for the development of GIS: • Custom-built geographical applications • DBMS for manage spatial data (vector and raster) • Support for different DBMS • Relational DBMS: • Oracle, PostgreSQL, MySQL, SQL Server • OR DBMS with spatial extent • Oracle Spatial and PostGIS

  3. What is TerraLib? • It is a product to be used by computer programmers to build customizablegeographical applications • Web-based co-operative development - www.terralib.org • Documentation, download and forum • Developed by:

  4. What is TerraView? • Geographical application built on TerraLib • It is an example of how to build a geographical application using TerraLib • ~ 7950 downloads in 2005 and 2801 in 2006 • www.dpi.inpe.br/terraview • Current release: 3.1.3

  7. A A C B B Intersection 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

  8. Image processing Application TePDI TerraLib Kernel DBMS Disk RAM TerraLib – Raster Data • TePDI – TerraLib image processing module: • Contains a set of functions to process raster data

  9. 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.

  10. TerraPHP • PHP extension • Visualize and query geographical data from a TerraLib database in Web applications • Free and Open source • Example of application: • TerraWeb
