GEO-REFERENCING What is Geo-referencing?  Technology allows us to take your old maps and drawings and assign real-world coordinate values to the elements on the scanned hard-copy originals.  These "intelligent images" can be assigned separate layers or themes for enhanced functionality within CAD or GIS. Your historical maps and hard-copy tracings can have functionality within modern GIS through correlation to real-world coordinates.  Kroll can scan and correlate your traditional maps, providing spatial intelligence within GIS (or CAD).

MAP CONVERSION (vectorization) We can selectively and carefully vectorize your historical drawings in a variety of GIS and CAD formats.  Our software allows for efficient vectorization of the raster using sophisticated line following routines.

DATA MAPPING We can represent your data (e.g., customer locations, competitors, etc.) efficiently and effectively, often blending GIS information with our own unique digital cartography.
