Name
IHO S-57 Files
Synopsis
Also known as S57. The IHO S-57 format is a vector interchange format used for maritime charts.
Developed by the International Hydrographic Organization (IHO). For more information about the IHO see http://www.iho.shom.fr/.
File listing
Individual S57 data files have an extension of *.000; for example, US1BS02M.000.
Data access/connection method
S57 access in MapServer occurs through OGR;
CONNECTIONTYPE
OGR
must be used.Specify a full path or a relative path from the
SHAPEPATH
to the .000 file for theCONNECTION
.The
CONNECTION
must also include a layer number (as per the layer number fromogrinfo
, but minus one).
Special notes
The underlying OGR code requires two files from your GDAL/OGR installation when reading S57 data in MapServer: s57objectclasses.csv and s57attributes.csv. These files can be found in the /GDAL/data/ folder. If you receive an error in MapServer such as:
msDrawMap(): Image handling error. Failed to draw layer named 's57'. msOGRFileOpen(): OGR error. GetLayer( 9) failed for OGR connection
you may have to point MapServer to these files using the
CONFIG
parameter in the main
section of your map file:
CONFIG GDAL_DATA "C:\gdal\data"
ogrinfo examples
Here's an example that uses ogrinfo
on an S57 file to get the OGR
index number:
> ogrinfo us1bs02m.000
