I presently have a set up in which I plot some measurements on some background maps. Things work fine, but I want to add the possibility to query the measurement data set by clicking on a measurement. The measurements have coordinates in lat lon and I only manage to query those data if I plot the entire map in the same projection. I have tried to reproject the query point using code like
$mapproj=$map->getProjection(); $layerproj=$map->getlayerbyname('mobil')->getProjection(); if($mapproj!=$layerproj){ $mapproj=ms_newProjectionObj($mapproj); $layerproj=ms_newProjectionObj($layerproj); debug(array($geopoint->x,$geopoint->y)); $geopoint->project($mapproj, $layerproj); // projects the point from the projection of the map to the projection of layer debug(array($geopoint->x,$geopoint->y)); } the debug function just dumps the data and it is clear that the point is correctly reprojected, but anyhow $map->queryByPoint($geopoint, MS_MULTIPLE, 1); never gives anything if the mobil-layer and the map are in different projections. Are there any ways to overcome this? As I am mostly working on maps from 60 deg north and upwards, geographical projection is not the projection of choise and I would prefer not having to reproject the measurement data.
