Summary

The shortestPath function returns different results depending on the unit used to specify the resolution. For example, {resolution: 0.0001, units: 'kilometers'} leads to a different result than {resolution: 10, units: 'centimeters'}. The reason for this is the created point grid for the A* algorithm. In addition, the spacing between the points in the grid differs from the specified resolution.

Example

Example 1:

• For {resolution: 0.0001, units: 'kilometers'}

GeoJSON file: grid_10cm_in_km.json

Example 2:

• For {resolution: 10, units: 'centimeters'}

GeoJSON file: grid_10cm_in_cm.json

Version

I tested this with @turf/shortest-path version 7.2.0

Note

I’d be happy to provide a pull request for this.
