2. Content Overview Why this topic? How the work was approached?
Problems, there were many!!
Future work
Questions

3. Overview Venus, Earth’s Sister Planet
Volcanism, Lava Production –type of lava (we are not in Kansas anymore)

4. Why? Why not? Has not been done before, (that I know of)
Curiosity, could it be done?

5. The Process

6. Data Analysis Metadata Selection of Site Getting a Clearer picture
Digitizing

7. Elevation
Elevation - Color
Slope

8. Elevation (color) + Slope (grey scale, at 50% transparency)

10. Down to Business Creating a layer for the flow channels
Defining a Co-ordinate system for the layer
Overlaying the new “drainage” layer and digitizing

11. Creating the layer

12. Name of the layer
Type of layer
Coordinate System
Will be used later
Might be used, if time permits

13. Layer Ready!

14. Digitizing Using the editor toolbar Start editing
This enables the flow paths to be digitized directly onto the map

15. When the editing is enabled the tool bar becomes active

17. Problems Cell size => 4640.998047 m x 4640.998047 m
This means that any apparent valleys are very big
The eastings and westings are reversed

18. Future Work More digitizing Adding flow direction
Converting the “drainage” into 3d
