Good morning,

first of all compliments for your toolbox.

I am trying to use it for an archaeological application, however I understood it works only with NAD83 projection and my data are in Italy, so I can't use NAD83.

There is any way to change this and to perform my analysis?

Thank you very much

You can use other coordinate systems, what error do you get when you use the desired coordinate system?

This is the error:

landcover_type = "nlcd", use_old_barrier = 0)

Thank you

ok, I solved the problem, it was caused by the ArcGIS version.

But now, the tool points out new errors:

Traceback (most recent call last):
File "C:\smt\toolbox\scripts\C_spreadgis.py", line 170, in <module>

landcover_type = "nlcd", use_old_barrier = 0)

    source_cell_elevation = numpy_dem[source_row, source_col]
IndexError: index -1120 is out of bounds for axis 0 with size 526

I already used an extent minor than the DEM and the landcover. Any ideas of what I'm doing wrong?

Thank you

Maria
