Yeah, I had a large bunch of NYC background data and ran into a similar problem, needed to #dissolve my features because of overlapping roadbeds and other features. After the #dissolve, couldn't get #intersect to pass 0%. #BadGeometry. I have a tendency to see bad geometry with file geodatabases and not with shapefiles. Came into this with a LiDAR-derived Tree Canopy layer as well. Can anyone form #Esri comment on why FGDB's have these problems and not shapefiles? Also, to let you know, my features have Z-values disabled before the intersect. ... View more

@lbarbato I actually fount this solution, to create vector points, to run a whole lot faster. Essentially, Zonal Stats just uses the cell centroid so why not just convert it to points and do intersect and then summary stats. So now I'm thinking of just converting my Kernel Density surface (the file I want to do Zonal Stats for) to a point file and just using Summary Statistics after an intersect of polygons to points. I'm just exhausted using Zonal Stats for 2 reasons, it keeps crashing using iterators AND 13-character limits for file names (I had to reprocess work to create unique IDs that took a whole day b/c my unique IDs were 15 characters long). Do you see any reason not to do this vector version of Zonal Stats? And how stable is your tool that you don't feel comfortable putting up on the forum? I may not be of help testing b/c I'm not much of a python programmer (I'm self taught modelbuilder and know very little python and even less VBA). Danny Danny ... View more

Right, thanks Esri. For anyone trolling the forums, let me just clarify what was going on; The .sdlic is the license file for the data, it does not activate the extension. Our organization has 2 ArcGIS license servers, however, our recent annual update did not include business analyst as an extension on our site-wide or departmental license server. So rather than point to a centralized license server to activate the Extension, what we did is set up a local license server on the machine we installed Business Analyst so that we can point to it for Business Analyst extension. We then had to register /authorize the extension and ArcInfo license locally. So when we use Business Analyst we point the machine to the local license manager and if we want to use, say, Spatial Analyst extension, we point to our license manager on our license server machine. ...

Curtis, I think I'm using Jamie's script which I benchmarked it in modelbuilder and would take many days to run (if my computer could even chug along for that long). I was just wondering if it would be significantly faster to run things outside of modelbuilder as a .py file vs. running in modelbuilder? The first workaround I came up with was to run zonal stats on each Feature split into its own Feature Class (so whereas one buffer distance Feature Class had 1541 records, I now have 1541 Feature Classes). Then I set up Iterator in modelbuilder to create Rasters for each FC (n=1541) (did this b/c I guess Zonal Stats converts vector to raster temporarilty to run) and then run through all the Rasters Zonal Stats individually using iterator. This worked until I ran into a few rasters that didn't produce any stats (why I don't know) and caused the program to crash - I'm curious if iterators in modelbuilder have a theoretical limit. So now I'm thinking of just converting my Kernel Density surface (the file I want to do Zonal Stats for) to a point file and just using Summary Statistics after an intersect of polygons to points.

Okay, Thanks!!! I'm batch processing a ton of radial and network buffers. Should I be running this in python rather than in Modelbuilder? ... View more

Jamie, will this run a lot longer than the regular Zonal Stats (it is right now for me, not sure if its working)? Also, I got an error at first that I had no FID field, my zonal feature had ObjectID instead of FID fields, so I AddField then CalculatedField FID to be the ObjectID values. Thanks, Danny ...

ArcGIS 10, File Geodatabase In addition if some of the Stata fields begin with underscores, at what point and in what software can I change these? I'm assuming FGDB does not like field names that start with underscores. ... View more

Every so often I forget that you can't create field names that are numeric. I do have an Esri question though, does <Null> values go to 0 in a Pivot for GDB? ... View more

update: used Jeff Jenness's tool - http://www.jennessent.com/ I'd appreciate it if someone at ESRI could explain how I can have the Shape_Length (not only the direction and angles of the line) portray spheroidic (?) distance. ... View more
