NOAA distributes marine charts in an OGR readable ENC format. This is also known as a S57 format.
- Download some charts from NOAA: http://chartmaker.ncd.noaa.gov/mcd/enc/download.htm
- Unpack them in an accesible directory
- Start GRASS
- Import the data using v.in.ogr
I'm not good at GRASS, but I was able to figure out that the above inputs a lot of data.
Looking into the v.in.ogr tool, I saw that 54 layers were included in my chosen chart, and one should probably make separate vector layers from each of them. v.in.ogr did not error out with the names of the layers as the tool says it will. It ran and imported lots of data. The layers included were:
ACHARE, BCNLAT, BCNSAW, BCNSPP, BRIDGE, BUISGL, BUAARE, BOYLAT, BOYSAW, CBLARE, CBLOHD, CTNARE, COALNE, DAMCON, DAYMAR, DEPARE, DEPCNT, DRGARE, DMPGRD, FAIRWY, FNCLNE, FSHFAC, FOGSIG, ISTZNE, LAKARE, LNDARE, LNDRGN, LNDMRK, LIGHTS, MORFAC, NAVLNE, OBSTRN, OFSPLF, PILPNT, PIPARE, PIPOHD, PIPSOL, PYLONS, RECTRC, RESARE, RIVERS, SEAARE, SBDARE, SLCONS, SILTNK, SLOTOP, SOUNDG, UWTROC, WRECKS, M_COVR, M_NPUB, M_NSYS, M_QUAL, C_AGGR
Does anyone have a script or command for automatically reading in these NOAA ECN data?
