You learn something new every day in GIS. If I open a shapefile attribute table, select an attribute, and use the field calculator to populate the field with an expression such as... attributeX / 0 I get an error all calculated values were invalid, no rows were updated. But attributeX / attributeY returns no error even if values in attributeY have zero values, In fact, it populates those values with zero values. This is disturbing. If I do this same test in a geodatabase I get null values for the zero division rows. I understand that there are data structure limitations. Shapefile fields are not nullable... but the shapefile example ought to give some warning!

Thanks for your help, Dan. Rest assured, I have a polygon layer that represents the bounding area of the survey that I will use to clip the Voronoi polygons with. Projected - Geographic coordinate system? I had no idea this would make such a big difference in the resulting polygons. I have projected the data and re-created the Voronoi polygons and the gap and overlap problems went away. Best to read the fine print! Problem Solved.

Ghislain, Thanks for looking into the issue. I have attached the gpk to this response.

Yes, Dan, I have. The input parameters are good, there is no other information other than what is shown below.

I have a feature class of building footprints and a surface (LiDAR highest hit - LiDAR last return). I am trying to use this surface to estimate the height of the buildings. Transferring the values from the raster to the polygons should be a straight forward operation using add surface information but that tool is useless and returns a 99999 error code. I tried the Zonal Statistics as a Table, then joined the table using the object ids. I want to populate an existing field in the feature class with the mean value from the zonal statistics output but the field calculator (both within the attribute table and the Toolbox tool) populate the attribute with the objectID value. This is odd behavior. Both data are in the same projection, UOM, datum.... I do not understand why this is happening. Is this a know bug or a problem specific to my installation? Should I accept that I should export the join to a new FC and just clean up the e-trash later?

Curtis, in this case the gaps and overlaps are a few feet over polygons that are 10 to 12 feet across. I did get confirmation from ESRI that this is a bug and will be fixed in 10.4.

I see that there are spatially duplicate points but with different attributes! That might be a problem. I have contacted the data creator to sort out the differences. Create Thiessen Polygons did not care if there were spatially duplicate points. I guess if you are going to be doing some coding, and want to produce a better tool, let the user know there are spatially duplicate points as a guard against such a thing. Thanks for throwing the error triangulation tools!

I noticed that the Create Thiessen Polygon Tool in ArcGIS 10.3 is not producing a continuous irregular tessellation across the analysis area. The resulting polygons have gaps and overlaps as confirmed by topology! I have not noticed this on other versions of ArcGIS. Can anyone confirm that this is happening on their installation of ArcGIS 10.3? Is there a fix, or does anyone have a script to replace Create Thiessen Polygons that works correctly?

I have in the past selected both the embed fonts and convert marker symbols to polygons options when exporting to PDF. I have determined that un-checking the convert marker symbols to polygons option results in a non-corrupt PDF. What would cause this change of behavior if I have not changed/upgraded my GIS software?

Jayanta, No, converting features to graphic is not a viable solution. The problem is persisting across all map documents with point symbols. I have had my Citrix profile reset by the IT Department, and a new installation of ArcGIS. The first map produced with the reset profile and the new ArcGIS installation produced a good PDF, any subsequent attempts have resulted in the same issue.

Or you could create a new attribute (call it modulo) and populate it with a modulo value using the Object ID and a value of say 10, then select all the records with a modulo value of 0 and and export only those records ( 1/10th of those originall records) to a CSV. That way you could preserve the original point values of the 30 m DEM and not end up with the point values of the resampled surface.

Chris, thanks for the reply. Unfortunately this is all happening on the same computer I have been using for a few years now. I am viewing the PDF on the same machine that has the ArcGIS 10.3 installation. I did not have this problem a few weeks ago. The point symbols in question are an ESRI circle 2 symbol and not based on a proprietary font. I have not (I cannot) install fonts due to restrictions imposed by my employer. My IT help department has tried rebuilding my Citrix profile and reinstalling the PDF driver to no avail.
