I'm a geo-idiot, and therefore I'm naturally having some difficulty getting anything to generate tiles for my geotiffs... I'm attempting to use mapnik & gdal for the render, and either tilecache or mapnikserv for the tiles/interface. So far I've got no luck with much. I'm wondering if someone might be able to offer some advice. I'm certain it's a problem with my configuration...
I'm *successfully* creating pngs with mapnik, via command-line, like this .... <code> mapfile = 'CapComplex.xml' map_output = 'CapComplex.png' m = mapnik.Map(2021, 2305) mapnik.load_map(m, mapfile) bbox = mapnik.Envelope(mapnik.Coord(-97.746225, 30.281582), mapnik.Coord(-97.733594, 30.267176)) m.zoom_to_box(bbox) mapnik.render_to_file(m, map_output) </code> The xml I generated with the help of Quantumnik ... it looks like this: <code> <?xml version="1.0" encoding="utf-8"?> <Map srs="+proj=latlong +datum=WGS84 " bgcolor="rgba(0,0,0,0)"> <Style name="CapComplex20090605183119637_style"> <Rule> <RasterSymbolizer/> </Rule> </Style> <Layer name="CapComplex20090605183119637" srs="+proj=latlong +datum=WGS84 " status="1" clear_label_cache="0" queryable="1"> <StyleName>CapComplex20090605183119637_style</StyleName> <Datasource> <Parameter name="file"> /Library/WebServer/Documents/Maps/Large/CapComplex.tif </Parameter> <Parameter name="type">gdal</Parameter> </Datasource> </Layer> </Map> </code> For mapnikserv, I'm using the following nasty little URL: http://localhost/cgi-bin/mapnikserv.cgi?MAP=%2FLibrary%2FWebServer%2FDocuments%2FMaps%2FLarge%2FCapComplex.xml&MODE=debug&FORMAT=image%2Fpng256&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&bbox=-97.746225,30.281582,-97.733594,30.267176&width=300&height=900 [I should add that even a simpler URL with just the mapfile, bbox, width/height/format doesn't help in terms of getting results] Which yields the following in the log file: <code> Process: httpd [22701] Path: /usr/sbin/httpd Identifier: httpd Version: ???
