Description
A region that extends outside the analysis extent or overlaps NoData areas can cause the region to be split into disconnected pieces. As a result, paths that would otherwise connect regions or make interior connections may not be made.
Connections for regions can only be completed within the analysis extent. Any NoData cells within the analysis extent will be treated as barriers.
Solution
To ensure that all connections are completed and no region is split into disconnected pieces, confirm the following:
- No region is outside the extent of the input cost raster.
- No region is within an area of NoData in the input cost raster.
