I read and understood the following GIS question and the accepted answer,

calculating-the-distance-between-a-point-and-a-virtual-line-of-two-lat-lngs

I can return the value in the ShortestLength variable (required for my project).

My question is: what is the measurement of this variable (ie.) Is it in kilometer or meter or do I have to convert it using the diameter of the earth?

I'm not sure. Can someone suggest a solution?

  • If you are in a projected coordinate system, it is going to be in the same units used for that coordinate system (e.g. if the units are meters than the measurement will be in meters). Commented Sep 11, 2014 at 12:30

If I understand the question and its answer correctly, you would need to use the earth's radius to get from the answer in that question to a measurement in kilometers etc.

See this page, in particular the sections on calculating the Bearing and Cross-track distance

  • I found the distance between (x3,y3) and (x4,y4) which gave the perpendicular distance.
