All the 'how to use this licence' stuff still at the bottom of this file.

Tried to run the latest BAL Tool and received this error:
Traceback (most recent call last):
File "H:\BAL_GA\BAL-master\bal.py", line 21, in
from utilities.sa_tools import extract_by_mask, reclassify, cal_slope_aspect

from scipy import ndimage
ImportError: No module named scipy

Failed to execute (BAL).

Assistance will be greatly appreciated and thank you

Input DEM and classified vegetation raster layers must be in the same directory. This is documented, but it would be easier to remove this dependency on the location of the input data.

Traceback generated when DEM and vegetation data are in different directories:

Need to update the hyperlinks in the documentation that point to http://www.as3959.com.au - this is an unofficial site that is intended to make it easier for people to locate the standard. Officially, we should only link to the Standards Online version.

The correct link is actually: https://www.saiglobal.com/online/Script/Details.asp?DocN=AS819920597136

Difficulties in setting Python paths for locked down computers - tests require python path to set location of python.exe

Can we develop this as a QGIS plugin? That would require modification of the interface and completely removing dependency on arcpy from the core algorithm (not just removing the Spatial Analyst dependency).

Have added Pythonpath to C:Python2.7, etc; tool still won't run. Ran unit tests through cmd (admin), some tests work (not all). Error message via Arcmap

Outputs highlight the 8 cardinal directions when the resolution of the data gets too fine (<1m).

I pushed the updated html documentation and the other pages (BAL etc) are fine, but the intro didn't seem to work. It's in the develop repo (and seems to be in the gh-pages repo?), but not displaying properly.
http://geoscienceaustralia.github.io/BAL/docs/training/intro.html

It may have been built incorrectly?

Some of the tests appeared to append .txt to the filename for the raster comparison output files. In some of the tests, the result is written to an xml file, which may be appending .txt to the basename.

Can't attribute this to an ArcGIS version problem

Would prefer to use GA standard colours for the documentation, but seems the sphinx_rtd_theme is fairly stubborn about allowing this sort of change.

The primary colours are (all in hexadecimal representation):
"#006983" - Deep teal
"#A33F1F" - Deep red/brown - for the BAL this is the prefered option as the main colour
Highlights: "#72C7E7" - sky blue
Secondary colours:
"#A5D867" - Pale green
"#CA7700" - Orange
"#6E7645"- Green/grey
"#988642" - Dark tan
"#003145" - Deep blue
"#5E6A71" - Grey/blue
