I'm trying to find a quick and accuarate way to measure the distance between 3 survey sites and all the designated sites within 10km. The survey sites are on a point vector layer and the designated sites are polygons, both on the same CRS.

I am new to GIS and so far I have only been able to measure the distance to the nearest designated site. As I said I need to know the distance to the nearest boundary of all the sites within 10km, not just the nearest.

  • distance as the crow flys or drive time? ET geowizards has a tool that will perform it. however it is not free. Calculates the distance for each feature of the Input dataset to the closest feature from the Near dataset. In the attribute table of the output the distance is recorded together with the ID of the closest feature. Inputs: Input Dataset - Point, Multipoint, Polyline or Polygon Near Dataset - Point, Multipoint, Polyline or Polygon Search tolerance - the maximum distance to search for features in the near layer in the units of the spatial reference of the Input Dataset

    I think it would be worth your while to have a look at the MMQGIS plugin. It is optional so you have to go to PLUGINS|MANAGE INSTALL PLUGINS then search for MMQGIS and install. Use the MMQGIS|CREATE|HUB DISTANCE command. But I am not certain of your use case, so have to try yourself. Help is at michaelminn.com/linux/mmqgis

  • Are you open to trying a Spatial Database solution like Spatialite or PostgreSQL w/ PostGIS?

This may be a bit more work than you want to do, but if you edit the layers with advanced digitizing enabled, you can create a new feature starting at a point and as you move the mouse around to other points and positions the distance is displayed in the advanced digitizing panel. You can then copy down the distance. You may be able to use a variant of this by drawing feature that connect various points and getting the dimensions for each significant edge.

This is definitely a work around or kludge, but you might want to try it
