I am adding a text/string field, "countyname", to a shapefile table. When I use Field Calculator to change the new fields to "Delaware", I get this error message The calculated value is invalid for the row with ObjectID = 0. For example, the calculated value may be too large for the field or you may be trying to add a string to a number field. This row will not be updated. Do you want to process the rest of the rows? It goes on with a warning about what happens if I say yes or no. I select Yes and the process fails. I don't know why this is happening or why it's referring to ObjectID = 0, when there is no such ObjectID. ObjectID starts with 1. ... View more

My csv has the following columns when I open it in a spreadsheet program: address, lat, lon, latold, lonold, sold, city, postal.code, add1, add2, internal.listing.id, X, Y. When I add the csv to ArcMap and open the table, I have: address, lat, lon, latold, lonold, add2, sold, city, postal.code, postal.code, internal.listing.id, new.lattitude, new.longitude, geo.lat, geo.lon, internal.listing.id. The list of column names in the table that opens in ArcMap is how the csv was arranged when I first loaded the csv into ArcMap. I have edited the csv a couple of times to reflect what's in my first sentence here. The column names that are showing in current table in ArcMap are wrong and they don't even match the data. For example, the data in the second "postal.code" column in the table actually appears as add1 data in my csv. I've removed the csv from ArcMap several times and added it again. I copied the sheet to a different directory and deleted it via ArcCatalog and then added a new copy and the ArcMap table still isn't correctly displaying the table as it's currently configured in the spreadsheet. The csv's name has remained constant, but I don't see why that should be causing trouble. What is going on? ... View more

I am using geocoding for first time. Actually, reverse geocoding. I have roughly 4,000 points that I want to find addresses for. I used the Reverse Geocoding tool (Geocoding Tools) and it worked. The thing is, I only have a MGRS option for Input Address Locator, which gives me "military coordinates". I would like regular U.S. address, like '123 Pine St, Pine, CA'. How do I get the Reverse Geocoding tool to give me addresses in that format. Or is there another tool that will convert the military coordinates to the format I want? ... View more

I made a four rasters in Raster Calculator with plans to mosaic them to one raster. One of the four resulted in an 8 bit unsigned pixel type. The others are 16 bit signed. I can't mosaic these rasters and I am guessing the different pixel type is the reason. I did check the projection, which is usually my problem, but that is not the problem.  The calculator script was (<raster_#> * 100) + raster_b The 8 bit raster came from a raster_# that had 3 values while the other raster_# had four values in the grid and I am guessing that this is causing the different pixel type in the results. I saw this thread​ and so I tried Copy Raster(Data Management) with the 8 bit result by setting the optional Pixel Type to 16 bit signed, but that still resulted in an 8 bit pixel depth. How can I get these rasters into one mosaic? ... View more
