2 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 DBMS TerraLib Jfddfjh gfsdfgdfssf fsdf fsdfsd sdfsdf J

3 What is TerraLib? It is a product to be used by computer programmers to build customizable geographical applications Web-based co-operative development - www.terralib.org 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 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 A B A B Intersection C

8 TePDI – TerraLib image processing module:  Contains a set of functions to process raster data TerraLib – Raster Data DBMS TerraLib Kernel Image processing Application TePDI DiskRAM

9 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. TerraLib – Raster Data

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