Would a "drill down" identify be appropriate for your application? Just query all of the layers?

Hi David... In my system the user SELECT the active layer (dropdown), and so he can "query" it selecting a a area or a point .... But, I´d like to take off that dropdown to select active layer... And when user click on map to query, I figure out what layer was clicked and query that...

Does your interface only allow them to click/select the topmost layer? Do you pick which layer is selectable? Do you let them pick which layer is selectable? Is it random?

And once you have the layer object use one of the query function to select the record? E.g. myLayerObj.queryByPoint ?

Hello guys... I have several layers (lines, points, poly) ... I´m developing a measure tool... User can click on map and I have to select that layer to calculate de Area with postgis... I´m trying to do that WITHOUT using "LAYER ACTIVE SYSTEM"... Is That possible using mapscript? How Can I find the nearest and toppest layer ? Thanks!
