I have a path which represents a proposed pipeline route. I need to find the length of the various landcovers the route crosses. Not area within a buffer. I found a ArcGIS help topic that kinda shows what I want to do: http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=Overlay_analysis

Is this the best way to do it? ie- convert raster to vector, overlay vector and line?

EDIT- the land cover file is a raster file.

    What type of data is your landcover? If it is vector-data i would not convert anything and just use the tool "intersect".

  • It's a raster file. I've been trying to convert it to a vector, but I've been having issues. Not sure if it's the size of the file or something with my QGIS installation. Apr 11, 2017 at 14:36

Use the tool intersect. Then in the new vector layer with the intersected lines add a field in the table with the "field calculator". In the new field specify $length as expression and be sure that the new field is a real variable. After the calculation will be easy to calculate what you need with MS Excel, just export the table.

You could also use the tool "Sum line length".

When you have vector-polygons and vector-lines, this tool will produce a new polygon-layer with an additional attribute --> the line length within the polygon.
