Transcript

• 1. ERWIN HERMAWAN G051060011 ITM-524 ADVANCED GIS 3D ANALYST APPLICATION “ FIND THE VOLUME OF WATER IN JATILUHUR RESERVOIR” Graduate Program Master of science in information technology For natural resource management SEAMEO BIOTROP Bogor Agricultural University 2007
• 2. WHY USING 3D ANALYST
• Makes spatial data look like the world it represent. Seeing the spatial data in three dimensional perspective makes it easy to grasp relationship that remain abstract in two dimensions.
• The 3D Analyst enables to perform a wide range of activities :
• Create realistic surface models from multiple input sources.
• Determine height at any location on a surface.
• Find what is visible from an observation point.
• Calculate the volumetrik diffrence beetwen two surface.
• Work with 3D vector features to make realistic models of the 3D world.
• Visualize the spatial data in 3D.
• 3.
• OBJECTIVE
• Find The Volume Of Water In Jatiluhur Reservoir using Arc View 3D Analyst application.
• DATA
• SRTM Data
• Jatiluhur Reservoir Coverage in *.shp format.
• 4. 1. Import data to grid format
• 5. 2. Result of data import
• 6. 3. Create Area of interest (AOI)
• 7. 4. Cropping the grid data using map calculator function.
• 8. 5. Result of cropping data using Area Of Interest in Grid format.
• 9. 6. Result of cropping data using Area Of Interest in TIN format.
• 10. 7. Cropping TIN data by vector (shp) format data.
• 11. 8. Result of cropping TIN data using Jatiluhur reservoir. How much water’s is holding by calculating volume Below the water surface ?
• 12. 9. Calculation of Area and volume statistics
• 13. 10.
• 14. 11. Result of calculating area and volume statistics.
• 15. 12. Layout.
• 16. That's all Thank's for your attention
• 17.
• When compared to planimetric area, surface area gives an idea about surface roughness. The larger the difference beetwen two values, the rougher the surface.
