GIS in Water Resources
Fall 2009
With contributions from Gil Strassberg (Aquaveo), Tim Whiteaker (UT Austin)

2. Subsurface Analyst Set of tools that are part of the AHGW Tools
Create and Edit 3D models of the subsurface including:
Borehole data (as 3D points or intervals)
Surfaces
Cross Sections
Volume models

3. Borehole Editor Display and edit vertical data along wells
Inputs are a Well feature class and a BoreholeLog table containing the vertical data

4. 3-D Features representing borehole data
Create 3-D Points and Lines representing data along boreholes
Well features
Tabular vertical data
3-D Point / Line features

5. GeoRasters (surfaces)
Rasters stored in a geodatabase (raster catalog)

6. Create 3-D features from GeoRasters
GeoSections
GeoVolumes

7. Hydrogeologic Unit Color Manager
Control the symbology of multiple layers based on a common hydrogeologic identifier

8. Cross Section Editor Goal Problem Solution
Display and edit cross section features in ArcMap
Problem
ArcMap isn’t suited for displaying and editing predominantly vertical features
Solution
Create new feature class where we transpose “z” to “y”
Build features with GP tools, edit with standard ArcMap tools
Show result in separate data frame

9. Section Lines and Cross Sections
Plan View
Cross Section

10. Cross Section Features
Major Grid
Boreline
Minor Grid (as map tick)
Panel Divider
Cross Section Panels Z S

11. Cross Section Editor Toolbox
GP tools form the building blocks
AHGW toolbar commands provide a friendlier user interface for calling the tools

12. Demos
Wells and boreholes
Cross section editor
Wells and time series
