Hi,
I want to start my project with a simple raster layer demo. After a few
weeks' trying different codes, I'm stuck. The raster image won't display at
all. I tried to generate vector map from shapefile and it's working fine.
The following is the map file:
MAP
NAME lpwUSA3
STATUS ON
IMAGETYPE PNG
SIZE 800 500
SHAPEPATH "/home/mapdata/"
EXTENT -6086744.000 -2784127 4278894 4485901
WEB
TEMPLATE '/opt/fgs/www/htdocs/lpwfirst.html'
IMAGEPATH '/opt/fgs/www/htdocs/tmp/'
IMAGEURL '/tmp/'
END
LAYER
NAME "Nighttime lights"
TYPE RASTER
STATUS ON
DATA "/home/mapdata/nitelti020l.tif"
END
END
The following is the html template:
<html>
<head> <title>lpw MapServer First Map</title></head>
<body>
<form method=POST action="/cgi-bin/mapserv">
<input type="submit" value="Click Me">
<input type="hidden" name="map" value="/home/mapdata/lpwnitelights.map">
<input type="hidden" name="map_web_imagepath"
value="/opt/fgs/www/htdocs/tmp/">
</form>
<IMG SRC="[img]" width=800 height=640 border=0>
</body>
</html>
The nitelti020l.tif image and nitelti020l.tfw world file are located in
/home/mapdata/ . The following is the content of tfw file:
769.4780
0.000000
0.000000
-769.4780
-6086744.0000
4485901.0000
I'm using the FGS installation Mapserver 4.4.1 and Apache-base 1.3.33 on
Fedora core 6.
Thanks in advance,
Leo
