Using MapServer 5.4.0: I have two shapefile layers in NC State Plane system, one in ft and one in meters. The PROJECTION in the layers allows the map to be drawn correctly.
My problem occurs when trying to use PHP mapscript to queryByAttribute. I am locating NC counties from two different shapefiles. Using the layer which is the same projection at the map there is no problem. Using the other layer, the bounds of the query result appear to be in meters and not ft. Is this normal? Do I have to make the conversion? Using mapserver 5.4.0 PHP mapscript: $ms = ms_newMapObj( $mapfile ); $ms->setSize($mapVpWidth,$mapVpHeight); $groupnames = $ms->getAllGroupNames(); for($i=0; $i < sizeof($layerNames); $i++) { if(in_array($layerNames[$i],$groupnames)) { $layerIndexes = $ms->getLayersIndexByGroup($layerNames[$i]); for($j=0; $j < sizeof($layerIndexes); $j++) { $layer = $ms->getLayer($layerIndexes[$j]); $layer->set("status", MS_ON); } } else { $layer = $ms->getLayerByName($layerNames[$i]); $layer->set("status", MS_ON); } } $layer = $ms->getLayerByName($layername); $layer->set('status', MS_ON); $layer->queryByAttributes($attribute, $expression, MS_MULTIPLE); $numresults = $layer->getNumResults(); if ($numresults < 1) { $err->msg = 'No results in '.$layername.' for '.$attribute.' = '.$expression.'.'; $error = true; } else { $result = $layer->getResult(0); $layer->open(); $shapeObj = $layer->getFeature($result->shapeindex); $layer->close(); $minx = $shapeObj->bounds->minx; $miny = $shapeObj->bounds->miny; $maxx = $shapeObj->bounds->maxx; $maxy = $shapeObj->bounds->maxy; $ms->setExtent( $minx, $miny, $maxx, $maxy ); $img = $ms->drawquery(); $tmpMapImg = $img->saveWebImage(); } *Layer data from mapfile: LAYER NAME "county_outlines" TYPE POLYGON MINSCALE 1200 MAXSCALEDENOM 3750001 STATUS off PROJECTION "init=epsg:2264" # NAD 83 North Carolina (ftUS) END DATA CountyBoundaryShoreline TEMPLATE void CLASS NAME "county lines" STYLE OUTLINECOLOR 128 128 128 END END END LAYER NAME "county_outlines2" TYPE POLYGON MINSCALE 1200 MAXSCALEDENOM 3750001 STATUS off PROJECTION "init=epsg:32119" # NAD 83 North Carolina (meters US) END DATA cb100_poly TEMPLATE void LABELITEM "co_name" LABELMAXSCALEDENOM 1500000 LABELMINSCALEDENOM 100000 CLASS NAME "cb100_poly" STYLE OUTLINECOLOR 200 0 0 END LABEL COLOR 0 0 0 #SHADOWCOLOR 218 218 218 #SHADOWSIZE 2 2 TYPE BITMAP SIZE tiny POSITION CC PARTIALS FALSE BUFFER 2 END END END _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
