Anybody can contribute an image of a world map in UTM? --Lev 19:44, 7 May 2004 (UTC)
Metric systems and maps within the UTM zones
I am working on systems producing generalised maps (presence/absence and density maps) based on the metric system in UTM-zones. This is fine as long as your data is from within one UTM-zone. But when the data extends over more than one zone several problems occur:
- how should we have a continous square system
- how can we keep our precision good enough
The solution on my side is to leave the UTM-based squares and continye by using a system based on longitudes and latitudes. Since it today is quite easy to calculate the square areas of any lon/lat square system density calculations is not a problem.
I would like to have some discussions on this matter on the page describing UTM-sones. What are the shortcomings when it comes to making maps based on UTM-zones...
