Hi,

I have only recently become aware of this specification exercise. I have a few thoughts, which might have already been discussed.


1.       I think it would be useful to have an attribute on the Position interface that indicates the source used to retrieve the location information for debugging purpose. This might also be useful if it's a tracking application and needs to log this data.

2.       I think the coordinate reference system could be an attribute of this interface as well. This will allow coordinate systems other than WGS84 to be used. EPSG codes can be used as possible values.

3.       Have we discussed  including the coordinate reference system (CRS) as an attribute of the PositionOptions interface, as  a way for the  application to specify what reference system it would like the location information to be returned in. If the underlying system API supports coordinate conversions, then this would be a very quick way for the application to get back the data it needs in the format it needs. Of course if coordinate conversions are not supported, then the coordinate reference system attribute on the Position interface would indicate to the application that no conversion was performed.

Thanks
Gopal
