Linear assets such as pavement, pipes, or bridges contain multiple coordinates. The asset must contain a minimum of two unique points. If only one point exists the import reports an error.
Polygon assets such as facilities, storm basins, or ponds contain multiple coordinates. The asset must contain a minimum of four points with three unique points.
Include any field to import into the Cartegraph database as well as the <Spatial X> and <Spatial Y> information.
Sort the coordinates for line or polygon records by asset ID and Spatial X or Spatial Y fields. Unsorted coordinates may result in a zig-zag line.
For polygon assets, the first and last coordinates of the polygon must be the same. If the data file does not contain the identical coordinates for the record, a duplicate of the first vertex is created to close the polygon.
