Transect spDS Models Coords

[Dave Pearce]

Hi all,

I'm wondering how I should include the coordinates for my transects since spDS models require the coordinates be a site x 2 matrix, but my transects are lines.

For reference my transects are in a shape file which I can manipulate and has starting and ending coordinates along with geometry for line strings. Below are an example of the transects.

Suggestions?

Thanks,

Dave

Hi Dave,

I’m not sure if this is helpful, but since you need a single coordinate, you could use the midpoint of the line. You can calculate it manually or use st_centroid() from the sf package.

Cheers,

Gilles
