Changed the helheim.poly file so the boundary is nicer
Likewise changed the kangerd.poly file
More changes to helheim mesh
GUESS WHAT THIS COMMIT IS FOR
Hopefully this is the final fix for the Kangerd mesh, Helheim mesh is still outside the data footprint
Added some warnings if interpolating points fails
Another fix to the helheim mesh, the script I was using didn't take into account how shapefile polygons duplicate a point
Added a script for getting streamlines, going to use this for better mesh generation
Streamlines script now uses bilinear interpolation
Merge branch 'master' into dev
