Hi Thorsten, Thanks for your work on the NEW queue and the quick feedback on this recent package.

The latter contains links to the three public domain datasets it's amalgamated from. To quote: " We present a high-resolution geography data set amalgamated from three data bases in the public domain: 1. World Vector Shorelines (WVS). http://shoreline.noaa.gov/data/datasheets/wvs.html 2. CIA World Data Bank II (WDBII). http://www.evl.uic.edu/pape/data/WDB 3. Atlas of the Cryosphere (AC). http://nsidc.org/data/atlas/ The WVS is our basis for shorelines except for Antarctica while the WDBII is the basis for lakes, although there are instances where differences in coastline representations necessitated adding WDBII islands to GSHHG. The WDBII source also provides all political borders and rivers. The addition of AC since 2.3.0 allows us to offer two choices for Antarctica coastlines: Ice-front or Grounding line. These are encoded as levels 5 and 6, respectively and users of GSHHG can choose which set to use. GSHHG data have undergone extensive processing and should be free of internal inconsistencies such as erratic points and crossing segments. The shorelines are constructed entirely from hierarchically arranged closed polygons. " http://www.soest.hawaii.edu/pwessel/gshhg/index.html > Could you provide theses sources as well in the package? Including references to these sources in the copyright file or README.Debian is no problem, including the databases themselves is a bit problematic besides the significant increase in package size. The WVS dataset can be ordered on CD for $196.25, or downloaded for free via the GSHHG dataset. http://www.ngdc.noaa.gov/mgg/shorelines/ To build the GSHHG dataset from source we'd need to implement the processing and assembly of the GSHHG data as described in their paper.
