Probably dont understand what exactly you are trying to achieve here but it is not as simple as map.getLayer(0) to get the topmost layer? 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! Paul
