ArcView Shapefile

The next version of GardenCAD will be able to function in tandem with Esri's GIS system (ArcInfo) because Shapefile output from ArcInfo GIS systems can be placed into a GardenCAD drawing. GardenCAD can work essentially an Archinfo ShapeFile viewer with the benefit of adding your own data.

The images below show part of the Hawaiian island group - with and without roads data showing. We downloaded a shapefile from the Internet was downloaded and imported it into GardenCAD.

Typical Shapefile data

The two shapefiles store the vector data (SHX and SHP) while the Dbase file (DBF) contains the text descriptions of all the items with links to the graphic data. Finally, there is the PRJ file which seems to store the GPS and mapping alignment for the data.

About Shapefiles - from Wikipedia

The Esri Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by Esri as a (mostly) open specification for data interoperability among Esri and other software products.[1]

Shapefiles spatially describe geometries: points, polylines, and polygons. These, for example, could represent water wells, rivers, and lakes, respectively. Each item may also have attributes that describe the items, such as the name or temperature.
