[Cartoweb-users] Zoom tools do not make anything

[Daniel]

In addition to Pierre Giraud's response:

1) When you use lat/lon data, you should define projections in your 
mapfile to get the whole app (including measures) working properly.

2) When you need to manage on-the-fly projections, don't forget that is 
time-expensive. For performances, you'd better project your data before 
(with command-line tools like proj or ogr2ogr, for example)

Yours,

dF
