The complete collection

Complete ArcGIS Pro project

An APRX project with 25 published-map adaptations, MAPX files, local vector data, the raster collection, and documentation. Counties, topography, and hillshade provide geographic context.

Raster layer package

A separate LPKX containing the same 90 rasters, organized by datum and data type. Add it to your own ArcGIS Pro project without the published vector maps.

Choose either package to start. Both contain the same raster collection, so you do not need both unless you want both delivery formats. Downloads are hosted directly in Azure Blob Storage.

Getting started

Open, explore, and keep the folders together.

  1. Complete project: extract the ZIP to a writable local folder. Open DS926_ArcGIS_Project/DS926_SubSurface.aprx. Keep the accompanying data folders with the APRX.
  2. Raster package: in ArcGIS Pro, use Add Data or the Catalog pane to add DS926_Raster_Layers.lpkx to your project.
  3. Read the catalog: the project includes docs/raster_catalog.csv and technical notes identifying each surface, its units, datum, and source.

ArcGIS Pro is required. PostgreSQL access is not required for the packaged map data. The project’s online topographic and hillshade references require internet access and provider availability; the geological and county data are local.

Keep the vertical references in view.

Raster groups included in the collection
GroupRastersHow to interpret it
NAVD88 elevations27Derived and reference elevations in U.S. survey feet.
Published NGVD29 elevations20Original published elevation rasters retain their source datum.
Thickness and depth24Distances in feet; not absolute elevations.
Classifications18Region and qualifier codes; use the supplied lookup descriptions.
Properties1Published transmissivity in its source units.

Published vector elevation attributes retain NGVD29. Changing a map projection does not transform those attribute values. The large 30-m land-surface DEM is excluded from both downloads; the project provides terrain-access notes. NoData, class zero, and physical absence are distinct.

These downloads are regional scientific interpretations and include derived analytical surfaces. They do not establish site-specific conditions. The desktop collection and manifest-selected web-service collection have different delivery scopes. See the technical methods for their relationship.
