I have a huge number of points (100000 points). Some of these have the same x,y coordinates. For example, 50 points are same in x,y then 100 points are same in another x,y coordinates and so on. Then the points are overlaid with each other and the user can’t see all of them. What I want to do is calculate the x and y of each point automatically and add a number at the end of each x and y.

For example:

Point a: x=65.23, y=26.76

Point b: x=65.23, y=26.76

What I want to do is:

Point a: x= 65.231, y=26.761

Point b: x=65.232, y=26.762

how are these points currently stored? gdb, shp or other (csv?) –  Mapperz Dec 18 '12 at 20:39

Here is a similiar topic that may be of interest, display stacked points –  klewis Dec 18 '12 at 20:47

Do you have an ArcInfo level license? Have you tried the Disperse Markers tool? –  mkennedy Dec 18 '12 at 20:51

Considering the number of points you're dealing with, batch changing your coordinates is probably not the best way to do this as it would probably make a mess of your map. A better way would be to add an attribute or a field that tells how many points occupy this XY location. –  Mintx Dec 18 '12 at 20:53
    
@Mapperz points are store in shp –  wetland Dec 18 '12 at 21:30
