I am using ArcGIS and have a shapefile with data points. They have UTM x and y coordinates, so I can plot them in ArcGIS with "Display XY data". Now I saw that many points are not exactly on the road, so I used the snap tool to fix that. Now I need the new coordinates, because the coordinates in the original Excel sheet of course did not change with the snapping.

Is there a way to extract the NEW coordinates?

  • "extract", do you want these updated coordinates in the shapefile or exported back to Excel? – artwork21 Feb 14 '18 at 13:39

You can use Add Geometry Attributes:

Adds new attribute fields to the input features representing the spatial or geometric characteristics and location of each feature, such as length or area and x-, y-, z-, and m-coordinates.

With geometry property POINT_X_Y_Z_M:

POINT_X: The x-coordinate of the point.

POINT_Y: The y-coordinate of the point.

POINT_Z: The z-coordinate of the point. This field is only added if the input features are z-enabled.

POINT_M: The m-coordinate of the point. This field is only added if the input features are m-enabled.

The new coordinates are part of the intrinsic geometry. If you want to have them visible in the attribute table, you can use the Add XY Coordinates tool.

The fields you add are static, i.e. they won't be updated if you modify your geometry again.

First, please check that your shapefile coordinate system is the same as your map coordinate system because maybe this causes the un-compatibility position of your points with the road.

Then to calculate new coordinates, open the attribute table of the points shapefile after editing positions

add a new field for coord x and a new field for coord y>> name it and chooses units and type.

Then calculate geometry >> calculate coordinates.

PS. also check your map units.
