[Geomoose-users] identify service

[Steve Dougill]

I am not sure why but it didn't work until I commented out one line of
code ... see below.  Thanks so much for your help and quick reply

 

The error I got was ... Fatal error - Call to function query by point()
on non object in identify.php line 91

 

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=lcc
+lat_1=42.33333333333334 +lat_2=44 +lat_0=41.66666666666666
+lon_0=-120.5 +x_0=1500000 +y_0=0 +ellps=GRS80 +datum=NAD83
+to_meter=0.3048006096012192 +no_defs");

                $clonePoint->project($projInObj, $projOutObj);

 

                $substArray['mapx'] = round($clonePoint->x,4);

                $substArray['mapy'] = round($clonePoint->y,4);

}else {

    $map->queryByShape($queryShape);

}

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 to get proj4 strings.

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?
