Point Density Error

HoganKnott

I am working with an excel document of lat/long data and I have displayed the xy data and exported the data and now I am trying to run a point density analysis, however I keep receiving the attached error. I am not sure how to create a spatial reference and I don't remember experiencing this problem in the past while running this tool. I am using coordinate system WGS 1984.

The layers must have a defined coordinate system, check its properties. If it says undefined, then you need to define it using the Define Projection tool.

In any event, if you are wanting to do density, you should actually project the layer to some projected coordinate system since units/square degree is pretty useless since it is not a consistent measure over the surface of earth.

It doesn't seem to want to work. Both the project tool and define projection tool ended with error 000289: failed to alter spatial reference.

You have to give the file the proper spatial reference so that it matches its extent. If the define projection tool doesn't work, then the Project tool will surely fail, since it depends on a properly defined coordinate system.

This error message basically boils down to that, you can examine a recent thread on that error number or view a recent thread where the confusion on what a file is defined as and what someone wants it to be is quite protracted.

Project Raster: Error 000289 Failed to alter spatial reference

try rebooting the computer, moving the file to a new, local drive, examine what the file extent is through its properties and try to get it defined appropriately. Good luck

so if my data is in decimal degrees what would I want to define as my coordinate system and how would I go about projecting this data

File received was empty, issue not followed up
