3.2 Distance Calculation in attributes (logic?)

jaimzj9 years ago

Dear Anton,

Say for example there is position update message, the first update for that device with no Location with GPS Coordiantes as 0,0

And the next position update is actual valid gps cordinates -42.420177, 173.707281

How will the system handle the distance calculation, will it calculate distance from 0,0 to -42.420177, 173.707281

Please advice.

Another question similar is, if in position table, valid is set to 0 (Will that row be counted in for distance calculation) or ignored.

It calculates all coordinates including invalid ones. You can enable filtering if you don't want to include those.
