v.in.mapgen fails to load coastline from NOAA's National Geophysical Data Center

[vesnikos]

when im trying to input a costline in mapgen format taken from the said site, I encounter the following:

v.in.mapgen input=/home/nikos/datagis/coastline/6888.dat output=coastline

Traceback (most recent call last):

Fixed in r42228.

with the following command:

v.in.mapgen -f input=/home/nikos/datagis/coastline/6888.dat output=coastline

I will let this for someone who knows the input format.

Is this still an issue? The file cannot be reached anymore. Is there some sample file or documentation if somebody would like to look at this?

Downgrading priority for old inactive ticket.

The NOAA shoreline extractor site is here:

​http://www.ngdc.noaa.gov/mgg/shorelines/shorelines.html ​http://www.ngdc.noaa.gov/mgg/coast/getcoast.html

It tries to get you to download Windows-only software instead of the online version for some reason, but the above site still works. v.in.gsghs (gshhg) in addons is the modern version of things.

note v.in.mapgen does the background work for v.in.lines, so not an unimportant module. The format is quite old, but old enough that it turns up every now and then in odd places, since it is a simple text format and at one point was open and widely supported.

If anyone can find a non-working sample I still remember enough about it to (probably) get the python version working. (I assume the shell script version from G6.4 is still ok?)
