comment Why Intersect gives ERROR 999999: Error executing function Invalid Topology [Too many lineseg endpoints]?
hi whuber -the use is in fire hazard analysis where different aspects/slopes and vegetation zones get a risk score and then these are simply added so that we end up with low, med, high fire hazard zones across the area. The issue is that we want to use the highest possible resolution but don't have it for the whole area.

comment Can concurrent processes be run in a single model?
Thanks blah238. It would be really great if we could do this and get arcgis to use multiple cores for operations. If you put your comment as an answer I will accept it for you to get status points.

comment ArcMap field calculator VBA question
This works great but I was trying to nest 'if' statements and can't. So if [grid_code] = 1 then f2= 2 end if if[grid_code] = 2 then f2=3.5 end if...etc. but this doesn't work? what am I doing wrong. I tried it before the end if and also tried elif. Also any idea why I get a warning message about field 1 being null and have to click yes to continue?

I did merge the slope and aspect and it worked but was not the right process...we needed to intersect and that doesn't work. To split I got a copy of the national 100k topo map grid and used that on the asp and slope seperately. The zone is covered by 30 map sheets.

comment If/then VBScript/Python code equivalent to SQL IN ('x','y',z') expression in ArcGIS Field Calculator?
the vb works well but I was trying to nest the if and it doesn't work. I tried adding if statements after the initial end if. Also I get a warning that field 1 is empty and have to click yes to continue...can this be stopped?

Thanks guys...doesn't a FGDB have a 1TB limit? I am just using 15GB max. The issue with a raster based model is that the whole region is represented by 30m DEM, the Eastern part by 10m DEM and portions of this by 1m DEM. So wouldn't Raster calculator work on the worst case scenario pixels (30m)?

Thanks. I have run repair geom 3-4 times and now the datasets don't report any errors. This usually works but I think the datasets are just to large as per whuber's explanation...

comment How to automatically email interim results from model builder?
Thanks...I guess I'll just have to use python. I accepted blah238's answer as he responded first but Ryan thanks for the extra info. I have the python email tool already but the extra functions in the ESRI scripts will be useful. Best.

comment How to automatically email interim results from model builder?
yup...I just hope that I don't have to do this. Surely there must be a way to capture the progress info from a tool that is running in model builder?

comment Efficiency of python script using SAGA and arcpy
still having issues but they are with implementing the python modules for saga on my system and not the core question here. So I am accepting this answer.
