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
borehole editor
Borehole Editor
  • Display and edit vertical data along wells
  • Inputs are a Well feature class and a BoreholeLog table containing the vertical data
3 d features representing borehole data
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

georasters surfaces
GeoRasters (surfaces)

Rasters stored in a geodatabase (raster catalog)

  • 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
  • Wells and boreholes
  • Cross section editor
  • Wells and time series
