  6. SPRINGThe Main Module

  7. Import / Export – General View Raster Representations: Tiff, GeoTiff, Gif, Sitim, RAW….. Vectorial Representations: ASCII-Spring, Dxf, ShapeFile, UNG, Surfer-ASCII, … Table Representations: Spatial and NoSpatial Tables Wizard CBERS

  8. Image Processing – General View

  9. Image Registration • Image Registration • The system provides statistical information in order to control the final quality of the registration.

  10. Segmentation • Segmentation: Identify homogeneous regions inside an image • Region: a set of contiguous pixels that are considered spectrally similar • It uses statistical attributes to determine similar regions. • The user controls the similarity criterions.

  11. Classification • It is based on pattern recognition procedures (objects) • The resulting image contains pixels that are mapped to classes of interest of the system user.

  12. Manipulation of Thematic Maps

  13. Measurements of Classes

  14. Buffering maps

  15. Vector to Matrix Conversion Original Vector Information Matrix structure definition Final Map in a Matrix representation

  16. Matrix to Vector Conversion

  17. Digital Terrain Modeling – General View

  18. Interpolators for rectangular grid models Closest Neighbors Simple Mean Weighted Mean

  19. Aplications:Slope Maps and Slicing The classification (slicing) of the Slope Image considering the classes (0-2, 2-5, 5-10 e >10) Rectangular Grid of Slopes

  20. Applications: Geometric Planar Projections Parallel projection using the shadowed DTM image as a terrain texture Projeção Paralela com Imagem Sombreada como Textura

  21. Tools for queries in the Database

  22. Table Module (Pie Chart)

  23. Module of Attribute Grouping :(Total Familiar Gain – Equal Step and Quantil) Districts grouped by Familiar Gains: Central Region: Rich Central Limit: Mean East Region: Poor South Region: Poor Quantil Equal Steps

  24. Attribute Queries Module * Table showing the result of the query

  25. Spatial Queries Module:(Topology : Intersection) Example: What are the districts that intersect the north-south line of the São Paulo subway ?

  26. The Analysis Module

  27. Analysis of Point Patterns – Intensity (kernel) Estimator Kernel Santos,S.M., 1999 Porto Alegre

  28. N N GeoStatistics: Kriging and Simulation Image of the Kriging Variance Image of the Kriging Estimation using an isotropic model

  29. Lineament Analysis

  30. Spatial Modeling – Suitability Analysis Soil Map Suitability Map Slop Map Simple Example using Boolean Operations

  46. Final Remarks • We use the SPRING as a general purpose GIS. At INPE we use many other GIS in our applications when it is necessary. • For specific applications we have been developing specific tools using TerraLib. (Example: TerraView, TerraCrime, TerraMe, SISMADEN,…) • The SPRING/TerraLib and products allow us to have a common GIS platform to change information and experiences with other groups working in geoprocessing stuffs. • The SPRING and TerraLib are used extensively by ours postgraduate students in their practical works, thesis and dissertation. • We participate on education programs with • Courses in posgraduation program • Short Courses, basic and advanced, using mainly the SPRING tools • Free Distribution of Satellite Images
