Content• Selection of the image• Contribution• Organizing data• Training• Screen digitizing • Possible CIM• Challenge and opportunity• Prospect
• Selection of Image based on• Spatial resolution• Spectral resolution• Radiometric Resolution
• QuickBird• < 3 m of multi-spectral resolution.
Contribution• World Bank and UN habitat
• Buying of image • Fagetalokoma woreda• ITC
• Geo-referencing the image • ILWIS• Local map datum (Adindan)• Position format (UTM)
Organizing of the data• 2 zipped CD• 8.15 GB• ILWIS 3.3• ILWIS 3.0
Visualization of the woreda Image with Kebele boundaries
• Training for field staff• On Arcview
• Import and Export of maps• Creating of shape file• Screen digitizing• Creating of project
• On ILWIS• Import and Export • Screen digitizing• Band combination• Map overlay
Creation of sub-image
Export sub image from ILWIS to Arcview
Zembela Kebele• Office digitizing
Based on • Tone• Fence• others feature
• 4270 plots• 8 days
• Field Digitizing Based on
• Committee knowledge • From 4270 to 2552 plots• 15 days
Office vs field
Possible Cadastral index map of Zembela kebele
Challenges of CIM Preparation• Low computer capacity• Software• Human capacity
Opportunity • The committee are cooperative• The field staff are interested • Farmers easily visualize and understand
Prospect • HRSI qualifying CIM• Speedy generation spatial information Next steep
• Densify Ground control
