One is generated through photogrammetry in a national grid coordinate system (OSGB36) and the other from a laser scanner. I had to import them in Cloud compare first to align the laser scanner and photogrammetry one. If I save them in .txt ArcMap (I'm using a 10.3 v) display only two points. As shape files .shp it says it can project them. So I sampled a region of my point cloud and saved them as csv ( so i could edit edits etc). Nevertheless i will need to upload the entire thing if possible so any suggestion is really appreciated!&nbsp;</P><P>-Generating a Near or Point distance table: if i use the "Generate Near Table" command the table gets generated fine and the different fields populated. The issues arise when I try to use the normal Near and Point distance tool. I know the syntax needs to be specific so I saved the file with the appropriate fields. When I use near it gives me the following warning: Output feature class empty. When i use the point distance it simply generates a table with nothing populated.&nbsp;</P><P></P><P>What I need to put as IN_FID are five points (taken with a total station), with my point clouds as NEAR. I wondered if the fact that i had so many points in the NEAR compared to the IN_FID could be the issue but even when I have one point cloud (laser scanner) as near and the other as NEAR (photogrammetry) I get the same issues.&nbsp;</P><P></P><P>I attach a PDF with some screenshot that I hope will help to support my points.</P><P></P><P>Many thanks in advance to any suggestion!</P><P></P><P>Samantha&nbsp;</P></BODY></HTML> Thu, 14 May 2020 07:33:01 GMT SamanthaDe_Simone 2020-05-14T07:33:01Z Issues with NEAR and Point distance https://community.esri.com/t5/arcmap-questions/issues-with-near-and-point-distance/m-p/706609#M1438 <HTML><HEAD></HEAD><BODY><P>Good morning,&nbsp;</P><P></P><P>I am a researcher focused on the use of point cloud data generated through SfM-MVS photogrammetry.
