I have an Excel spreadsheet with the columns longitude, latitude and TR. I add them as XY data to ArcMap with long as the x data, lat as the y data and TR as the value. This gives me a 12 x 12 series of points, representing a grid of data values in the Arctic.
I want to the convert this to a raster. I've tried using both Point To Raster and Feature To Raster. Point to Raster gives me an unknown 9999 error and Features to Raster gives me an
000861 error - 'Sheet1 is not valid'.
In both cases I enter
TR in the 'field' section and leave the cell size to default
