Digital Mapping

Engineers, Surveyors, Designers and clients utilizing Geographic Information Systems insist on high quality digital land data. It is also necessary for this data to be available in a variety of formats. In response to this need, SDC has developed our digital mapping service to produce flexible digital data of the highest possible quality in a timely cost efficient manner. To accomplish these goals, Spatial Data Consultants uses the latest software and hardware solutions and has assembled a team who is dedicated to achieving the highest level of performance and producing products exceeding industry standard.

Using KORK system software, which is used extensively in the mapping industry for data collection and editing, we can automatically clean and restructure captured data with a minimum of technician interaction. This enables us to produce more accurate and uniform data. These automated processes result in faster data collection, higher levels of accuracy, and generally results in a cost savings to the client.

SDC uses direct stereo digitizing, Digital Terrain Modeling (DTM) and contour interpolation for the production of topographic databases. We feel strongly that the DTM method of capturing surface model data will produce consistently accurate contours and result in a cost savings to the client.

Quality control is the most essential feature of the mapping process. With this in mind, we have developed a quality control and assurance process that involves both automated and manual hands-on procedures. This approach ensures that sufficient and accurate data are transferred into the data collection and graphic edit process. Following this QC and QA process we can then augment the data with additional graphic, attribute or text requirements to meet client specifications. All work is accomplished with high performance, interactive workstations. After graphic enhancements have been accomplished, finalized digital data can be integrated into various industry standard CAD and GIS software packages.

Final edits of the data are accomplished in the specified delivery format to ensure immediate usability by the client and to allow a final visual edit of the product to be delivered.
