Data Edit, Conversion
All stereocompiled and otherwise produced vector map data is subject to finalization/processing and quality control review/edit initially on dedicated Zeiss CADMAP and Cardinal Systems VrTwo editing stations and subsequently in the target GIS/CAD environment.
Quality control of digital terrain and elevation model data is performed using 3D visuals, generated check contours, and Zeiss PROSA progressive sampling technology.
Editing/quality control of generated/compiled contour and compiled planimetric feature data is accomplished using batch and manual processes which yield a clean, seamless, layered feature database. Our edit stations allow review of the vector mapping against a corresponding digital orthophoto image backdrop to verify the completeness and overlay accuracy of the vector data.
In the final data edit and conversion process, translation tables are developed based on the specified layering scheme/database design and reviewed with the client for approval. Conversions are performed using direct binary data translators (e.g., AutoCAD, MicroStation) or through DXF/DGN exchange formats (ArcGIS, Intergraph GeoMedia/MGE).
The conversion process includes importing the data into the target environment and directly reviewing it for conversion anamolies, batch editing and topology building as required with subsequent visual review, creating/populating attributed fields as needed, assigning tolerance and projection, and final checking for empty coverages, fuzzy and dangle tolerance, coordinate precision, properly defined projection, and proper attribute item definitions.
Metadata is FGDC-compliant or other specified form is produced directly through the GIS platform or using an independent program such as USGS Tkme.
GIS application work performed by our staff has included E911/addressing system development, hydrographic route system development, parcel-based impervious surface area calculations, watershed modeling, change area detection, GIS platform data overhaul, and a variety of other projects.Back to Our Services
