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

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

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

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 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

Section Lines and Cross Sections Plan View Cross Section

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

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