I am working with a centreline of equidistant points. I want middle points of those points. For example, if the distance between each of the points is 24.99m. I want to locate the exact middle point at 12.495m. How can I do that with ArcMap tools, not Python? This is a shapefile.
If you combined the two points of which you want middle points into a multipoint,then you can use the tool "FeatureToPoint".It will create new point based on each multipoint ,the new point is just the centre point of the two original points.The tool "FeatureToPoint" is located at "Data management tool——Feature".The version of ArcGIS is 10.X.
If you are trying to locate the midpoint interactively, there is a midpoint tool that can be used while editing. http://desktop.arcgis.com/en/desktop/latest/manage-data/editing-fundamentals/creating-a-point-or-vertex-at-the-midpoint-of-two-locations.htm
