Unique Custom Chart Creation...

Digital charts, the raster (digital) version of a paper map. A paper map that has been scanned at a high resolution and saved as a JPEG, PDF, TIFF, etc.

Vector charts, charts displayed as a series of lines, points and polygons. Each point feature is represented by a single coordinate pair while lines and polygon features are represented as ordered lists of vertices. Attributes are associated with each vector feature.

Recreational charts, booklets of small scale charts for a particular area of interest such as Chicago’s harbor, the San Juan Islands, intracoastal waterways and the Erie Canal.
