Hi, I have a point file that has a value column in its attribute table.  I want to get the values of each point in a polygon (hexagon) cell. I know that tabulate area will give me a count of points per hexagon. Is there anyway to get the values?  A tool or a script?  I could look at each hexagon and manually add the values found in each hexagon but I have a lot of points so automation would help immensely. Thank you in advance for your time and help. ... View more

:confused:Hello to the GIS community, I am using the tabulate areas command.  I keep getting different error messages.  Here are two messages that I have received: Unable to allocate space for polygon ERROR 010024: Error during conversion. Failed to execute (TabulateArea). End Time: Wed May 19 14:24:51 2010 (Elapsed Time: 1.00 seconds) The maximum record length has been exceeded. Failed to execute (TabulateArea). End Time: Thu May 20 09:59:40 2010 (Elapsed Time: 50.00 seconds) The feature zone is hexagons with an area of 1000km2. The diameter of the hexagons is 3.9 km. The zone field is 'Unit_id', the unique value per polygon. The feature zone shapefile has 9,712 records. The feature class is a 4km2 GRID npp.  The class field is the ???Value??? column.  The GRID has 6,690 records. The processing cell size is the same as the GRID cell size. I created a subset of the feature class GRID and recreated hexagons that would just cover the subsetted GRID. I thought lessening the size of the files might solve the space error.   I also tried to increase the area of my hexagons to 5000km2. It still failed. I looked through the old user forum to see if these issues have been addressed.  I rebuilt the VAT table of my GRID.  I still received errors. Any suggestions? Thank you in advance for your time and help. ... View more

Hello, I am using a polygon data set as my zone data. The zone field that I want to choose is not given as an option.  The only two options that are offered have the attribute properties of being string fields.  Are numeric fields not the proper format? Do I need to convert my numeric field to a string field? Thank you advance for your time and help. Debra ... View more
