WSG84 format

[Dima]

Can anybody help me on how WGS84 format works? For example: How can I calculate the position when walking x distance under y angle from one point to another? Is there any website which explains this?

 

Thanks,

Dima

WGS84 is a "datum" not a format.

 

A datum is like a starting point.

 

NAD27 and NAD83 are other Datums. I've been told that NAD84 and WGS84 are extremely close. Enough that any difference does not matter.

 

I think what you are asking is about a coordinate system.

 

Using Latitude/longitude can get tricky because it is not base 10.

 

Using UTM will be more along what you are wanting, as the base unit is a meter.

For short distances, like walking, it doesn't matter what projection you use (UTM, Lambert Conformal Conic, or Integerized Sinusoidal [ugh]), you can calculate relative coordinates using bearing and distance.

 

For longer distances, a projection that is azimuthal is better (represents angles better).
