I have a village shapefile of India and a river shapefile containing major rivers and tributaries polylines of India.

How do I calculate the distance between any village and the river nearest to it using QGIS?

  • Have a look at join attributes by nearest.

Since QGIS 3.8 you can use Join Attributes by Nearest from Processing Toolbox (settings should be self-explaining, fields with attributes and join distance are added) and since QGIS 3.16 you can also use the expression overlay_nearest(), e.g. overlay_nearest('riverlayername',"attributename_you_want",limit:=1)[0]. This will get an attribute of the nearest river. To calculate the distance via expression, use it this way: distance($geometry,geometry(overlay_nearest('riverlayername',$currentfeature,limit:=1)[0])). Just change 'riverlayername' to the name of the layer containing the rivers.

    Or, as a variant: length(shortest_line($geometry,array_first(overlay_nearest('riverlayername',$geometry))))

    It is sufficient, starting from the layer village: distance ($geometry, overlay_nearest ('riverlayername', $geometry) [0]) there is no need for limit: = 1 because it is by default for the closest one;
