How many bands are in the raster? ________________________________ From: mapserver-users <mapserver-users-boun...@lists.osgeo.org> on behalf of Moen, Paul T. <pm...@nd.gov> Sent: Thursday, December 13, 2018 10:32:44 AM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] PHP MapScript queryByPoint fails successive query.
I am trying to query a raster at 2 points in a single php file using php mapscript. 1. I create a map object. 2. I get a layer object from my raster 3. I create 2 point objects. 4. I query the raster layer object with queryByPoint using point 1 and it is successful, except that it gives me 4 results even though I pass in MS_SINGLE. 5. I query the raster layer object a second time using queryByPoint with the second point object I created and the query fails. My questions: Shouldn’t this be possible? If so, what am I doing wrong? Why are 4 points returned when I pass in MS_SINGLE? I have tried using MapScript 7.2.1, 6.4.4 and 7.0.7 with the same results.
