Hi, I am a student and trying to manage xy data. I have a text, that include 4 things (x, y, Angle, Velocity). The problem is that when I display the xy data in gis, the anlge and velocity should be string(eg.1.231321321231). But actually, it was regarded to be Long in Gis. So most of the number cannot be illustrate in the table.
Can anyone tell me how can I change the data field type??
