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
