GPS coordinates for YRA Racing marks in San Francisco Bay
See NEWS.md for recent updates.
This project contains GPS coordinates for nearly all racing marks in the San Francisco Bay and some other "interesting" marks. The information here was collected from multiple sources:
- Existing web sites
- NOAA ENC charts
- Sailing clubs
- USCG Weekly Light List Volume6
You can download the list in multiple formats or look at them using Google Maps which also allows to search for these marks on the map using the mark name (e.g. "YRA-18").
Of course I do not claim that any of this information is correct and strongly advise not to use this for navigation. Having said that, if anyone finds mistakes or has additions, please feel free to send me updates.
For most marks that are listed in the Weekly Light List, the description
contains the light number in
 for the Lightship).
The coordinates are offered in multiple formats. However, the canonical source is the CSV format and all other formats are generated from that using GPSBabel.
As an example, the GPX file was generated using
gpsbabel -i unicsv -f San_Francisco.csv -o gpx -F San_Francisco.gpx
Right now I offer the following formats (all but CSV generated from CSV):
CSV simple text format with coordinates in decimal degrees (e.g.
GPX very common format. This can also be directly used as a layer in the excellent OpenCPN chartplotter and navigation software.
DMM CSV with coordinates in degrees and decimal minutes (e.g.
DMS CSV with coordinates in degrees, minutes and decimal seconds (e.g.
W122 21 32.281)
NOAA CSV with coordinates in degrees, minutes and decimal seconds (e.g.
122-21-32.281W). This is the format used in the NOAA light lists.
SHP format commonly used in mapping applications
HTML simple text version
If you need another format, drop me a note and I might add it. Of course you can also always use GPSBabel yourself.
