S-57 data
More to come
Basics
- Import with v.in.ogr
- There is some more info and links on the Export for GpsDrive wiki page

Accessing S-52 symbology
S-57 is the data format. The S-52 standard contains the standardized coloring and symbology for electronic navigation charts. We want to view the S-57 data through the lens of the S-52 rules. Some ideas for that:
- GRASS interface: (wishlist prototype) display imported S-57 data (v.in.ogr or v.external) using S-52's coloring and layer-order info. Some environment will be information like lighting level and hull depth (start at 0) will be needed
- View with the OpenEV plugin (functional)
- Create the dataviewer as a QGIS plugin (wishlist user app)
libS52
- GPL library
- housed in OpenEV CVS as contrib/S52/
How to build
- Install build dependencies
- Install OpenGL and X11 -dev packages (X11/Xlib.h and GL/gl.h)
- PROJ.4 for proj_api.h?
- Build it:
make # for s52glx simple test program make default # for libS52
Run simple s52glx test program
- Get ENC data
- Edit s52test.conf with the full path to your ENC chart datafile (*.000 file)
- Run it with ./s52glx and you should see a new window with all layers rendered
OpenEV S52 plugin
- Copy libS52.so to GDAL's lib directory
- run ldconfig ?
- Set environment variables
export S57_CSV=/usr/share/gdal export OGR_S57_OPTIONS="LNAM_REFS:ON,UPDATES:ON,\ SPLIT_MULTIPOINT:ON,PRESERVE_EMPTY_NUMBERS:ON,\ RETURN_LINKAGES:ON"
- test:
openev/openev/gvtest -ogr=/path/to/ENC_ROOT/US3NY01M/US3NY01M.000 -OR- openev/contrib/S52/s52testdyn (s52test.conf will need ENC path ajusted)
GRASS S-52 interface for rendering S-57 data
- TODO
- build little command line app to output coloring and layer order info which can be fed to d.vect et al?
QGIS S-52 plugin for viewing S-57 data
- TODO
- anyone have ideas?
