[ka-Map-users] addObjectGeo error

[Paul Spencer]

Harry,

lat and lon are a bit misleading.  They should be in whatever units  
your map projection is in.  If you happen to be using a latlong  
projection then they would be in decimal degrees.  I'm pretty sure  
that you can find an algorithm to convert degrees/minutes/seconds to  
decimal degrees, I don't happen to have one handy (would it be as  
simple as d + m/60 + s/60?).

myKaMap should be declared somewhere as a global variable (its in  
startUp.js in the default interface) and assigned a new instance of  
kaMap in the onload event of the window.  If you've been stripping  
index.html then you likely removed startUp.js :)

Cheers

Paul
