comment How to show average walking distance to closest point in census tract in ArcMap?
Are you wanting to calculate the distance based on the centroids of the polygons, or the closest vertex along the polygon boundary, or...?

comment Cripplingly Slow Performance While Georeferencing in ArcMap 10.1
Where is your data being stored? Can you upgrade to 10.2 to test differences? Are you connected to network drives?

comment Field is not nullable but Field is nullable Box is checked
What type is your field? Also, just a note that Null and 0 (zero) are not the same thing. Null is literally an empty cell.

comment Creating Thiessen polygons gives ArcGIS ERROR 000537 error in converting points to Voronoi Polygons?
You may have some errant points that fall out of the tool's extent capabilities, or there may be some other issue with the feature class. You might look at the feature class and see if there are any obvious issues, and/or attempt to repair geometry, or export the feature class to see if that fixes something. Lots of possibilities.

comment Problem with Elevation Profile Graph
I'm not sure why the original was weird. It could have to do with the DEM you based your elevations on, or as others have suggested, the way the lines combined. Anyway, glad the manual method worked. I'm not sure if that is the truthful answer to the question though, since it is more of a work around. Any thoughts on that moderators?

comment Problem with Elevation Profile Graph
Are your original lines parallel to each other before combining, or are they continuations of the same route? Also, what kind of elevation profile do you get if you just create a manual trace of the route?

comment shapefile damaged after editing in ArcMap 10.0
So, is there a question here? I can't tell what you want. Is your corrupted shapefile after editing repeatable? Does it corrupt every shapefile or just the one? Etc., etc.

comment How would I flatten a projected vector dataset to georeference a historic map to it?
What other data will be overlaid on these GLO plats? If those datasets are also properly projected, then the historical plats may never line up very well. There are certain assumptions/restrictions that need to be made whenever you attempt to overlay historical with modern day data.

comment Can ArcGIS Online navigate and identify large GIS datasets?
Are you wanting to store this large dataset(s) in ESRI's cloud, or are you going to store it on your own server? I can tell you that storing large datasets in ESRI's cloud can get expensive, and/or take up a lot of account credits. Also, you may have performance issues vs publishing through ArcServer.

comment How do you calculate the area of polygons which overlap a buffer around a point?
The only way I can think of to do it is programmatically, unless you separated each nest buffer by a query or export, and ran an intersect on each iteration. Not sure how to do either of those methods in QGIS though. Hopefully, some gurus will chime in. Good luck!

comment How do you calculate the area of polygons which overlap a buffer around a point?
Do your nest buffer zones overlap each other? If so, then in effect you want to run an intersect of ponds with each nest buffer, right?

comment How combine different geometry types into the same feature class
Why do you need them together? What calculations/display/analysis do you want to perform that requires them to be in the same layer? If we know what you are trying to do, then we may be able to come up with better alternative solutions.

comment Model Builder: Enable / Disable parameters based on Conditions / Preconditions
So, you want the tool to gray out a parameter input when the checkbox is unchecked, and then to ungray/allow it when it's checked?

comment How to split lines at vertices in ArcGIS for Desktop with Basic level license?
GME has a Polygons to Polylines tool as well. So, it's got you covered either way. QGIS also has a Polygons to Lines tool.

comment How to split lines at vertices in ArcGIS for Desktop with Basic level license?
If ET-GeoTools doesn't work as you would like, then you might try the Geospatial Modelling Environment add on, which has the Polygons to Points tool. GME supports Arc 10.0/10.1, but not 10.2 yet. Extract Nodes in QGIS can also be a fall back.

comment How to split lines at vertices in ArcGIS for Desktop with Basic level license?
So, you don't have the license level to use Split Lines At Vertices, but you still want that functionality in your model? Or you want to use other tools in your model that accomplish the same thing, but don't require the Advanced license? I'm not sure that's possible in an automated way using just ArcGIS.
