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
