HRU creation with own soil + land use data

[Camilla Negri]

Hi there,

I have prepared my own land use and soil data based to make the HRUs and I keep bumping into issues reading the look up tables. 

Specifically I always seem to get these  ValueError messages :

for land use lookup:

 line 557, in populateLanduseCodes

nxt = int(row['LANDUSE_ID'])

^^^^^^^^^^^^^^^^^^^^^^

ValueError: invalid literal for int() with base 10: 'RD'

for the soils:

line 754, in populateSoilNames nxt = int(row['SOIL_ID']) ^^^^^^^^^^^^^^^^^^^ ValueError: invalid literal for int() with base 10: 'ONALT~~~~~A'  

I am using the 3.4 QGIS version FYI.

Any suggestions or hints as to what I could try here?

Many thanks and best wishes,

Camilla Negri

The LANDUSE_ID values in the landuse lookup table should all be
integers: values found in the landuse raster. Similarly with the soil
lookup table. Have you switched the columns?
