I'm using current version of ArcGIS Pro. I have a city boundary. I am trying to make a 1 mile buffer around it, and then create a 1000 x 1000 foot grid overlaid over the boundary. I have my units set in my document to feet.</P><P>The buffer command has an option where you can choose units, which I've chosen miles. But when I run it and measure it, the actual distance comes out to about 1.3 miles, which is about 2 km.</P><P>When I run the fishnet command, it does not have an option where you can select units but I believe it uses the project units. When I run it and measure it, though, it comes out to 3,280 x 3,280 feet, which is actually a square kilometer.</P><P>I'm probably missing something obvious but as far as I know everything in the project is set to Imperial units. Thanks in advance.</P> Sat, 06 May 2023 15:33:06 GMT https://community.esri.com/t5/arcgis-pro-questions/units-on-buffer-and-fishnet-coming-out-metric/m-p/1286472#M68868 RyanSmith_elkhart 2023-05-06T15:33:06Z https://community.esri.com/t5/arcgis-pro-questions/units-on-buffer-and-fishnet-coming-out-metric/m-p/1286476#M68870 <P>What is the coordinate system of your input city boundary and what is the projection of your map/project?<BR />For the buffer tool, I'd set the 'Method' to 'Geodesic'.&nbsp; When you measure your buffer, ensure the measurement option is also specified as 'Geodesic'.&nbsp; I'm thinking you have a Web Mercator of Plate Caree projection for your project/layout and are at a latitude where you're experiencing relatively large planar measurement inaccuracies.</P><P>For the fishnet tool, it does not matter how you've set up any project settings to only show imperial.&nbsp; It's likely your input data coordinate system is in metric metres.&nbsp; If so, the cell size width and height will be in metres.&nbsp; The simplest way around this would be to use a cell height/width of 1609.34.&nbsp;</P><P>However it seems strange that your measurement is accurate for the fishnet but not the buffer.&nbsp; It would be good to see your input data coordinate system, your project/map coordinate system/projection, and any screenshots of your inputs into the tools and the measurements taken after.</P> Sat, 06 May 2023 17:06:14 GMT https://community.esri.com/t5/arcgis-pro-questions/units-on-buffer-and-fishnet-coming-out-metric/m-p/1286476#M68870 DavidPike 2023-05-06T17:06:14Z
