Mylar Map Digitizing/Georeferencing

Client:

NOAA- National Geophysical Data Center

Pupose:

Provide NOAA with vector files of the bathymetric data for Lake Huron.

Processes/Services:

High resolution scanning, georeferencing, vectorizing, and attribution of lake contours. The delivered product was ESRI .shp files and georeferenced rasters. These maps were all hand drawn and very light on mylar. The results of that made it very hard to decipher contour lines and values. The QC portion of this project was vital to ensure accuracy. NOAA distributes this data through their site at The Great Lakes Environmental Research Laboratory (GLERL).

Deliverable to Client:

ESRI .shp files and AutoCad .dxf files.

Cost:

$6,245

Vector File Creation

Client:

United States Geological Survey, APS

Pupose:

Provide USGS Aeromagnetic Study Team vector files of their study areas.

Processes/Services:

Georeference, vectorize, and attribute Afghanistan geo-magnetic and flight path maps. The objective of this project was to provide digital GIS files of existing geo-magnetic fields and the flight paths used for those studies. These will help in determining the remaining areas of study and the best paths to employ in the gathering of this information.

Deliverable to Client:

ESRI .shp files and ASCI II, .xyz files.

Cost:

$13,500.00

Seamless/Collarless Topo Maps

Client:

State of Colorado Division of Water Resources

Pupose:

Provide the Colorado Division of Water collarless and seamless topos in Geotiff format to be implemented into their proprietary software application.

Processes/Services:

Scan, georeference, and convert to collarless/seamless files. DDS scanned 2,500 topos and mylars . DDS then georeferenced the maps using ArcView 8.0 and used a proprietary process to create collarless/seamless maps.

Deliverable to Client:

Geotiffs with .tfw files along with raw scans of each map for archival purposes.

Cost:

$28,000
