I need to locate a bunch of points off a known point. My known point being 0,0. Like 23 feet in the X direction and 45 feet in the Y direction. How can I do this in ArcGIS Pro 2.2.4?
To achieve the above in a manual way you can duplicate the layer in the map and setting two whereclauses to the layers. One to only show the feature with FID 92:
and the other to show the other you mentioned:
Next would be to use the Near Table to determine the distances of all the points (91 to 113 without 92) to point 92:
The resulting table will have the information to calculate the OffsetX and OffsetY:
Next you can join the Near Table to the point featureclass (the one that shows FID 91 to 113 without 92)
And then fill the OffsetX and OffsetY fields with the values from the joined table:
After that you will have the appropriate values in the fields:
See attached for the shapefiles. FID Points 91-113 are the points I'm after. Point 92 is my basepoint.
So as far as I see there are two options:
Both can be valid options. If you could share a sample of your data that would help to understand what you have.
Full disclosure, I'm a newbie at this. I have reread your(Xander Bakker) comment about the field calculations several times and I think I finally understand. Are you saying to use the XY coordinates of a know point and subtract them from the other points to get the difference? Thus giving me the distance between the point? If so that should work. So then I just need to convert the XY coordinate to Feet. Don't suppose you know of an easy way to do that?
Do you ant to overwrite the point locations or create a new featureclass with the calculated locations? Do you have a sample of your data that you can share? It would make it easier to understand.
Is this more of a Euclidean distance problem? Is your data in projected units or will you only consider your Origin Point as 0,0?
I already have all of the points in a feature class. I just need to find x,y coordinates of their locations from a specific point(Known Base Point). That make sense?
If you have these measures in a table, you could calculate the new X and Y coordinates with 2 field calculations and simply use display XY to create a featureclass of these locations.
