STM viewshed analysys

Hi Christine,

Not sure what you mean by my Output file is in Meters? Is the itiff file containing the viewshed result not at the correct location?

Thanks,

Mathieu

Hi Mathieu,

The file and STM that I am working in have a coordinate system of NAD 83....., US Feet but the iTIFF file that is created is NAD83....,Meters. Changing the Coordinate System after attaching generates an error message that the file is read only.

Have you every come across this?

Thanks

Hi Christine,

If the coordinate system is just NAD83 the unit is not feet or meters, but degrees....

Usually a STM in degrees (a LatLong GCS) should not be created because it would not display correctly in isometric view.
