gis - Tilecache failing to generate tiles using Mapnik -

-

i downloaded australian osm extract , moved database called gis using osm2pgsql.

i have changed generate_tiles.py generate tiles australia:

bbox = (-180.0,-90.0, 180.0,90.0)  render_tiles(bbox, mapfile, tile_dir, 0, 5, "world")  minzoom = 10 maxzoom = 16 bbox = (101.1,-6.9,165.5,-45.9) render_tiles(bbox, mapfile, tile_dir, minzoom, maxzoom)

when attempt generate tiles with: export mapnik_map_file="osm.xml" && export mapnik_tile_dir="/tmp/tilecache/" && ./z0generate_tiles.py

lots of directories created in /tmp/tilecache png tiles. tiles have state boundaries , country names , there appear highways. but.. when navigate address: http://localhost/osm/tilecache-2.11/index.html see countries , states, no labels , no streets. figure permissions issue accessing postgis data. have gone psql , issued: grant privileges on database gis public

in /etc/tilecache.cfg have:

[cache] type=disk base=/tmp/tilecache [osm] type=mapnik mapfile=/home/(my user_name)/bin/mapnik/my_osm.xml spherical_mercator=true tms_type=google metatile=yes [basic] type=wms url=http://labs.metacarta.com/wms/vmap0 extension=png

it seem mapnik not able communicate postgis. have logged postgres , executed: grant privileges on database gis public

i generated my_osm.xml file following:

./generate_xml.py osm.xml my_osm.xml --dbname gis --user (uname) --password (pword) --accept-none

it generated without errors.

that's far can take it. new files being created when accessed via web, don't have road information. ideas?

one comment:

  • generate_tiles.py , tilecache different applications , don't know each other. so, tilecache config read tilecache application. but, if tilecache used 'tms_type=google', have done, cache schemes used each program should match.

couple things check on missing roads:

  • sometime problems old geos libraries can lead lacking data imported osm2pgsql, make sure there lot of rows in plant_osm_line table:

    select count(*) planet_osm_line;

  • also, make sure running latest mapnik version, @ least 0.7.0, ideally 0.7.1.

  • try rendering few maps nik2img.py , make sure mapnik output warnings might causing - common issue can missing proj4 epsg definitions epsg:900913

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt
