3D Analyst - Watershed, Tomohon

  1. 1. 3D Analyst With Watershed in Tomohon Agripolitan Area Yaulie Deo Rindengan ID Student : G051054041 Lecturer : Ir. Hartanto Sanjaya, PM
  2. 2. <ul><li>Software : </li></ul><ul><li>Global Mapper 7.0 </li></ul><ul><li>3Dem </li></ul><ul><li>ArcGIS 9.2 </li></ul><ul><li>Objective : </li></ul><ul><li>Make a project about 3D Analyst with : </li></ul><ul><ul><li>a. Delineate a watershed area. </li></ul></ul><ul><ul><li>b. Find the streams of the rivers </li></ul></ul><ul><li>Data : </li></ul><ul><li>SRTM </li></ul><ul><li>Tomohon Image </li></ul>
  3. 3. Create DEM from SRTM Data N01E124 (Global Mapper) UTM coordinate with GeoTiff (With 3Dem)
  4. 4. Some Stage Processing in ArcGIS 9.2 Using the Fill tool to removing an error sink ( by the interpolation process ) Using Flow Accumulation tool to generate a raster map showing flow Using Flow Direction tool to generate a raster grid showing the direction of flow Using Stream Link tool for assign each individual stream segments a unique number Using Watershed tool to generate Watershed
  5. 5. Result …. Converting the DEM to Integer using Raster Calculator Removing 2 nd Error Sink
  6. 6. Result …. Flow Direction to Generating a raster grid Flow Accumulation to Generating a raster map
  7. 7. Result …. <ul><ul><li>Generating Stream Channel Using Raster Calculator </li></ul></ul>Generating Stream Link
  8. 8. Result …. Tomohon Watershed Area
  9. 9. Tomohon Area Using 3D Global Mapper
  10. 10. Tomohon Area Using 3D ArcScene With River
  11. 11. Tomohon Area Using 3D ArcScene With Road
  12. 12. Tomohon Area Overlaying
  13. 13. Tomohon View
  14. 14. Thank You
