Title: Projected Lava Flow on Venus


1
Projected Lava Flow on Venus
  • Michael Boyce

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

3
Overview
  • Venus, Earths 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
Slope
Elevation - Color

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

16

17
Problems
  • Cell size gt 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
