Hi All:
I am extending a package I have to allow users to provide a crs string, which
will eventually through some other packages be sent to sf. I like to try and
make at least minimal tests that inputs are valid. Is there some existing code
that will check if a string is a valid crs string?

perfect. Thank you. I thought there must be a function in one of the
packages to check.

Hello,
This is my first post to this list. I am a beginner in R and GIS and I work as
researcher at Spanish Institute of Oceanography.
I have a ncdf file from the Copernicus webpage with monthly primary production
data from the Northeastern Atlantic. In my case, the chlorophyll concentration
Dear community,
Is there any way to create a spatial weight matrix based on road distance?
I am trying to use the road distance between two points instead of
euclidean distance.
I've seen that there is a package named osrm. Can anyone give some advice?
Thank you in advance.
Regards,

Rather than converting an object of class 'SpatialLines' or
'SpatialLinesDataFrame' to the spatstat class 'psp' and then converting it to
the spatstat class 'linnet', it is safer and more efficient to convert the
SpatialLines* object directly to class linnet using
as.linnet.SpatialLinesDataFram
I finally got back to this. Unfortunately this did not work.
It still doesn't like PKG_CONFIG_PATH and now pcs.csv was not readable. It
did not exist in 'share/gdal' but I found it in miniconda3/pkgs/libgdal* so
I copied it to share/gdal.
