A Web-Based Geotechnical GIS

Abstract EN

A web-based Geotechnical Geographic Information System (GeoGIS) was developed and tested for the Alabama Department of Transportation.

This web-based system stores geotechnical information about transportation projects, such as subsurface data, construction drawings, and design information.

Typically, this information is in a report or plan sheet format, but raw geotechnical data can also be accommodated in the GeoGIS.

The goal of this system is to provide easy access and storage for all geotechnical and subsurface structural information from across a state.

Access through a secure web interface allows for keyword searches and interactive map selection.

The web-based GeoGIS has four geotechnical layers (project, bridge, foundation, and soil boring) that can be displayed on a road map, aerial photos, or USGS 7.5 minute quadrangles.

For testing purposes the GeoGIS was populated with multiple document types, formats, and sizes.

In all cases, the system performed above expectations.
