Subsurface Analyst
GIS in Water ResourcesFall 2009
With contributions from Gil Strassberg (Aquaveo), Tim Whiteaker (UT Austin)
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
Subsurface Analyst
Borehole Editor
• Display and edit vertical data along wells
• Inputs are a Well feature class and a BoreholeLog table containing the vertical data
• Create 3-D Points and Lines representing data along boreholes
Tabular vertical dataWell features
3-D Point / Line features
3-D Features representing borehole data
Rasters stored in a geodatabase (raster catalog)GeoRasters (surfaces)
Create 3-D features from GeoRasters
GeoSections
GeoVolumes
Hydrogeologic Unit Color Manager• Control the symbology of multiple layers based on a
common hydrogeologic identifier
Cross Section Editor• Goal
– 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

Cross Section Editor Toolbox
• GP tools form the building blocks
• AHGW toolbar commands provide a friendlier user interface for calling the tools
Demos
• Wells and boreholes
• Cross section editor
• Wells and time series
