I use QGIS 2.8.3 or 3.4 whatever works better.
I need to calculate the mimumum distance between all points of 2 different point layers. I was reading this post https://gis.stackexchange.com/a/62212/147194 and used the distance matrix tool accordingly. Now I am unsure what the output layer contains. The point input layer had 488 feautres and the target point layer had 605 features.
But why does the output layer contain of 3801 ?
The last column of the output layer probably gives the distance but in which measure unit?
I need to 2 this process for 2 other point layers and want to be sure that I am on the right track before I continue.
Is 'Distance Matrix' the easiest way to calculate the minimum distance between all points of 2 different point layers?
And what does the number at 'use only nearest (k) target point' stand for?
Following the instructions (see link above) I put '1' but without knowing why?
