I have two layers, one is a point layer of schools and another is a polyline layer of streets. The end goal is to create a buffer along the lines that is 20 feet from the centerline that goes 1 mile in distance from the school/point layer.

Perhaps I am not phrasing this question correctly so if it is already answered somewhere else, I would gladly accept that.

I am using QGIS, which I am brand new to using. I have several years experience with ArcGIS (student license expired since graduation).

Would the plugin for QChainage accomplish this? Has anyone used this plugin?

If I had access to ArcGIS, it looks like this would be a Linear Referencing question. Would Locate Features Along Route be able to solve this problem?

Edit: Measuring the distance between lines and points in QGIS looks like it's finding the distance from a point to a line which is not what I am asking. I am asking to find the distance along a line from a point.

  • In that case, this post might help you: QGIS calculate distance of point along a line. If it still doesn't help, please consider adding an image to your question to make it clearer. – ArMoraer Apr 27 '16 at 13:29
  • Buffer the schools by 1 mile. Use those buffers to select the roads/lines within the buffers (might have to extract the data). Now buffer the lines by 20 ft. – mkennedy Apr 27 '16 at 17:09
  • @mkennedy the distance will be different, particularly if the road turns or going on to a new road. – giscard78 Apr 27 '16 at 17:42
