https://community.esri.com/t5/arcgis-pro-questions/distances-units-and-why-different-from-manual/m-p/1154126#M52832 <P>I use 'Generate near table' to measure distances from a set of points to a point of interest. I got my results, but the distances came in some odd units. To resolve this issue, I manually measured the distances for 10 randomly selected points. The outcome was that my 'unit' equals approx. 131 km - I wonder what unit it could be. Even more worryingly, whilst 131 was the average multiplier, it differed point-by-point from 111 to 171 which is quite a lot. Why could this be? Has anyone met with a similar problem? Thank you.</P> Wed, 16 Mar 2022 00:50:49 GMT Mikhail 2022-03-16T00:50:49Z https://community.esri.com/t5/arcgis-pro-questions/distances-units-and-why-different-from-manual/m-p/1154126#M52832 <P>I use 'Generate near table' to measure distances from a set of points to a point of interest.

On my map the system was set to Web Mercator, I changed it to British National Grid...and got the same 'strange' units again. What am I doing wrong?</P> Wed, 16 Mar 2022 23:35:06 GMT https://community.esri.com/t5/arcgis-pro-questions/distances-units-and-why-different-from-manual/m-p/1154582#M52903 Mikhail 2022-03-16T23:35:06Z https://community.esri.com/t5/arcgis-pro-questions/distances-units-and-why-different-from-manual/m-p/1154595#M52905 <P>Sorry, I kept trying and know the answer now. Had to set the method to geodesic. Thank you again for your help!</P> Thu, 17 Mar 2022 00:43:51 GMT https://community.esri.com/t5/arcgis-pro-questions/distances-units-and-why-different-from-manual/m-p/1154595#M52905 Mikhail 2022-03-17T00:43:51Z
