[Geomoose-users] identify service

[Len Kne]

Hi Steve

Look for the following lines in identify.php

                                if($queryShape->type == MS_SHAPE_POINT) {
                                                $point = $queryShape->line(0)->point(0);
                                                $map->queryByPoint($point, MS_MULTIPLE, -1);
                                                $substArray['mapx'] = $point->x;
                                                $substArray['mapy'] = $point->y;
                                } else {
                                                $map->queryByShape($queryShape);
                                }

And change them to:

                                if($queryShape->type == MS_SHAPE_POINT) {
                                                $point = $queryShape->line(0)->point(0);
                                                $map->queryByPoint($point, MS_MULTIPLE, -1);

$clonePoint = $point;
$projOutObj = ms_newprojectionobj("proj=latlong");
$projInObj = ms_newprojectionobj("+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext  +no_defs");
$clonePoint->project($projInObj, $projOutObj);

$substArray['mapx'] = round($clonePoint->x,4);
$substArray['mapy'] = round($clonePoint->y,4);
                                } else {
                                                $map->queryByShape($queryShape);
                                }

This is a quick way to do this - you will need to change $projInObj to match your map projection (the example above is web Mercator).  See www.spatialreference.org<http://www.spatialreference.org> to get proj4 strings.

Subject: [Geomoose-users] identify service

I am using the identify service and by default it returns the x,y coordinates of the clicked location in ground coordinates ... It looks like this is set in identify.php.  Has anyone changed the code to give lat long coordinates instead?
