Software : Global Mapper 7.0 3Dem ArcGIS 9.2 Objective : Make a project about 3D Analyst with : a. Delineate a watershed area. b. Find the streams of the rivers Data : SRTM Tomohon Image

Software :

Global Mapper 7.0

3Dem

ArcGIS 9.2

Objective :

Make a project about 3D Analyst with :

a. Delineate a watershed area.

b. Find the streams of the rivers

Data :

SRTM

Tomohon Image

Create DEM from SRTM Data N01E124 (Global Mapper) UTM coordinate with GeoTiff (With 3Dem)

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

Result …. Converting the DEM to Integer using Raster Calculator Removing 2 nd Error Sink

Result …. Flow Direction to Generating a raster grid Flow Accumulation to Generating a raster map

Result …. Generating Stream Channel Using Raster Calculator Generating Stream Link

Generating Stream Channel Using Raster Calculator

Result …. Tomohon Watershed Area
