Subsurface Analyst
Subsurface Analyst is a suite of tools in ArcGIS for creating and editing subsurface objects which follow the Arc Hydro Groundwater data model. Subsurface Analyst tools enable the creation and visualization of 3D hydrogeologic models, starting with classification and visualization of borehole logs, creation and editing of cross sections, and generation of 3D volumes.

Geoprocessing Tools

  • Image:Toolbox.png Subsurface Analyst
    • Image:Toolset.png 3D Import:
      • Image:Tool.png Import GeoVolume From XML: Imports 3D GeoVolume features (features representing volume objects) from an XML file.
      • Image:Tool.png Import GeoSection From XML: Imports 3D GeoSection features (features representing cross sections) from an XML file.
    • Image:Toolset.png Features:
      • Image:Tool.png Create Borelines: Creates 3D line features that represent borehole intervals (e.g. hydrostratigraphy, and screens). The BoreLine features are created from points representing the borehole locations and related tabular data representing the 3D intervals along boreholes.
      • Image:Tool.png Create BorePoints: Creates a set of 3D points from the BoreLine features. The points inherit the attributes from the BoreLine features.
      • Image:Tool.png Create GeoSection Feature Class: Creates an empty GeoSection feature class (multipatch) based on the Arc Hydro Groundwater Data Model. Appropriate fields based on the Groundwater configuration file will be created.
      • Image:Tool.png Create GeoVolume Feature Class: Creates an empty GeoVolume feature class (multipatch) based on the Arc Hydro Groundwater Data Model. Appropriate fields based on the Groundwater configuration file will be created.
      • Image:Tool.png Rasters to GeoSections: Creates new GeoSection features in the Arc Hydro Groundwater data model from a Raster Catalog representing a depositional sequence.
      • Image:Tool.png Rasters to GeoVolumes: Creates new GeoVolume features in the Arc Hydro Groundwater data model from a Raster Catalog representing a depositional sequence.
    • Image:Toolset.png TIN:
      • Image:Tool.png Rasters to GeoVolumes: Creates a projection TIN for use with the Rasters to GeoVolumes tool.
    • Image:Toolset.png XS2D Editor:
      • Image:Tool.png Create XS2D Boreline Feature Class: Creates a feature class to store 2D cross section borelines. These vertical lines show well locations and stratigraphy in the wells. This function only creates the feature class. Separate functions are used to populate the feature class.
      • Image:Tool.png Create XS2D BoreLines: Imports boreline features for display on a 2D cross section by reading from a layer of wells and a table of borehole information associated with the wells. The boreline features reveal stratigraphy observed in the wells, and include attributes providing the distance from the section line defining the cross section and the distance along the section line.
      • Image:Tool.png Create XS2D Grid: Creates feature classes to store 2D cross section grid lines. This tool creates a major grid feature class and a minor grid feature class. Both horizontal and vertical lines are created. The tool is designed to produce grid lines that can be set as the grid for a data frame. Each grid feature includes an attribute 'GridValue' that provides the value represented by the line.
      • Image:Tool.png Create XS2D Line Feature Class: Creates XS2D_Line feature classes for the SectionLine features. Information about the new feature classes are stored in the XS2D_Catalog table.The tool can be applied to a selection of SectionLine features. If no features are selected, the tool will be applied to all features in the SectionLine feature class.
      • Image:Tool.png Create XS2D Panel Divider: Creates and populates a feature class to store 2D cross section panel dividers. These vertical lines show vertex locations from the section line defining the cross section transect.
      • Image:Tool.png Create XS2D Panel Feature Class: Creates an empty feature class to store 2D cross section panel features. These polygon features represent hydrogeologic units or some other subsurface phenomena. Only an empty feature class is created. Use other tools or manual editing to add features to the feature class.
      • Image:Tool.png Create XS2D_Catalog Table: Creates a system table used by the Arc Hydro Groundwater tools to manage 2D cross section features.
      • Image:Tool.png Reverse Section Line Orientation: Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc). This is useful for 'flipping' section lines that will be used to create cross sections. Cross sections typically start a X = 0 at the beginning of the section line, and are drawn to the right with increasing distance along the section line. If the 'from' point is on the opposite end of the section line that the user intended, this tool can be used to reverse the orientation of the line so that the 'from' point is where the user intended for the beginning of the line to be.
      • Image:Tool.png Scale Features: Rescales features in the Y direction.
      • Image:Tool.png Transform GeoSection to XS2D Panel: Creates XS2D Panel features (2D Polygons) from GeoSection (Multipatches) and SectionLine features.
      • Image:Tool.png Transform Polygons to XS2D: Creates XS2D line features from SectionLine features and a raster. For each section line multiple XS2D Lines are created, based on underlying polygon features. Raster values are sampled along a SectionLine and then transformed to an XS2D line.
      • Image:Tool.png Transform Raster to XS2D Line: Creates XS2D line features from SectionLine features and a raster. Raster values are sampled along a SectionLine and then transformed to a XS2D Line.
      • Image:Tool.png Transform XS2D Panel to GeoSection: Creates GeoSection features (3D multipatches) from XS2D_CrossSection features (2D Polygons) and a SectionLine feature.

Toolbar Tools and Commands

  • Borehole Editor: An interface for interacting with 3D borehole data. The editor provides an interactive interface for visualization, classification, and editing of borehole data such as stratigraphy, screens, and casing interval.
  • HGU Color Manager: HGU Color Manager is a tool for managing the symbology of multiple layers based on a common attribute. The tool is used for symbolizing different spatial instances of hydrogeologic units such as volumes, cross sections, borehole intervals, geologic picks, and outcrops.
  • XS2D Wizard: The XS2D Wizard creates a new set of feature classes for representing a 2D cross section based on a specific SectionLine feature. The wizard creates a new data frame to which the XS2D feature classes (XS2D_Panel, XS2D_BoreLine, XS2D_PanelDivider, XS2D_MajorGrid, and XS2D_MinorGrid) are added. Using a separate data frame for each 2D cross section allows the features from each cross section to be visualized independently.
