I have a layer containing lanterns (point layer, yellow blocks) and a layer containing hectometer signs (point layer, blue dots). In order to find the closest perpendicular distance from a lantern to a hectometer sign, I created a line between the hectometer signs (line layer, red).
I know the length of the lines between the hectometer signs and I know the distance from each lantern to the nearest hectometer sign. However, I need to know the distance from each lantern perpendicular to the nearest red line.
Right now I'm stuck because in my ArcGIS I am not licensed to use the Nearest tools. I think I have to use a Python script but I can not figure out how to start. Does anyone know how to tackle this?
