[mapserver-users] GPX file viewer with mapserver

Thu Mar 13 20:31:17 EDT 2008

Hi,
I want to make a .gpx file viewer with PHP/Mapscript and OGR extension, but
I got errors. Can you give me advices? Do ORG extension of PHP support .gpx
file? Is my map file correct? Thank you very much!

Here is the errors:
-------------------------------------
*Warning*: [MapServer Error]: msDrawMap(): Failed to draw layer named
'12-MAR-08'. in *F:\ms4w\Apache\htdocs\vd\gpx\gpx.php* on line *9*

*Warning*: [MapServer Error]: msOGRFileOpen(): Open failed for OGR
connection `test.gpx'. File not found or unsupported format. in *
F:\ms4w\Apache\htdocs\vd\gpx\gpx.php* on line *9*

*Fatal error*: Call to a member function saveWebImage() on a non-object in *
F:\ms4w\Apache\htdocs\vd\gpx\gpx.php* on line *10
------------------------------------------

*Here is my map file:

            #SYMBOL 0
        END
    END
END

END
------------------------------

And my php code:
------------------------------
<?php

dl('php_mapscript.dll');
dl('php_ogr.dll');
//phpinfo();
$map_path="F:\ms4w\Apache\htdocs\vd\gpx\\";

$map = ms_newMapObj($map_path."gpx.map");
$image=$map->draw();
$image_url=$image->saveWebImage();

?>
