The standard in Bivouac is that all stored data is lat-long and WGS84. However when we display trip and road waypoints, we allow you to also display several formats. The formats are below. I'm assuming you understand datums (WGS84 versus NAD27), and are familiar with truncated UTM grid references like "154-310". If not, read Map Coordinate Systems.
Below is a complete list of the waypoint formats: (To make them short, assume the datum is WGS84 unless otherwise stated.)
Combo Shows both NAD27Canada UTM and WGS84 Lat-Long
DD Lat-Long in Decimal Degrees, datum is WGS84
DM Lat-Long, Degree minute, datum is WGS84
DMS Lat-long, Degree minute second, WGS84 (for BC Basemap)
UTM Full UTM code, datum is WGS84
UTM-NAD27C Full UTM code, datum is NAD27Canada
This format combines UTM and Lat-Long. If only one UTM is shown, it is WGS-84. The combo format also shows distance in km. Certain roads like Ashlu main also show milepost distances.
DD The "DD" means "Decimal degrees", and because datum is not specified, assume WGS84 For example:
The "WGS84" means that the decimal degrees are in WGS84 format.
49.12345-123.66666=Start of hike
DM The "DM" means "Degree-Minute". (And because no datum is specified, assume WGS84. Note the degree and minute symbols. The minutes themselves are a decimal number.
The DMS means "Degree-Minute-Seconds". Again, it is WGS84.
This format gives you the UTM co-ordinates, instead of the lat-long. It gives you the full UTM code, including the zone.
In the above, "9V" is the zone. (See separate descriptions of UTM) This is the format you might use if you were coordinating with BC Basemap. You would want your lat-longs in Degree-Minute-Second (DMS) format, rather than Degree-Minute (DM)format.
9V 434554 6414742=East end of bridge
Same as above, but NAD27 instead of WGS84. Use this for old maps.
