DELILAH Survey Data: Contour & Perspective Plots


The DELILAH survey data were collected using the Coastal Research Amphibious Buggy or CRAB, a 10-m tall self-propelled tripod. Position of the CRAB was determined using a Geotronics 140T auto-tracking total station. This system aims an infrared beam at a reflecting prism mounted on the CRAB and measures the spherical coordinates associated with each position. The Geodimeter 140T tracks the CRAB and samples at 1Hz. There were errors associated with the Geodimeter (vertical noise and drifting) which are described in the Survey Section.

Combination Contour and perspective plots are available in two different file types, Graphics Interchange Format (GIF files) and Computer Graphics Metafiles (CGM files). The gif files can be viewed using an Internet browser. The cgm files are vector based and supported by most CAD, word processing, and drawing programs. The filenames are labeled by date from October 1 through October 19, 1990. The date in the filename is preceded by the letters "MG"(for minigrid). For example, the file for October 3, 1990 is labeled MG901003.GIF. An example plot is shown below.
