Coordinates British National Grid

[isabelmm@ugr.es]

Hi everybody!

I woud like to start modelling a estuary in Mohid, and the first problem that I have is that my bathymetry is referred to a National Grid System, specifically the British one. I found in Mohid wiki just the following coordinate types can be used:

1 - Geographic coordinates
2 - UTM coordinates
3 - Portuguese military coordinates
4 - Simplified geographic coordinates: in Degrees
5 - Metric coordinates referred to the origin of the grid
6 - Circular coordinates
7 - NRLD - Dutch metric coordinate system

What should I do? What type of coordintes do you recommend me to use, geographic or UTM? Which transformation should I apply?

Thanks a lot!

I always use long/lat in wgs 84 that corresponds to 4 - Simplified geographic coordinates: in Degrees
