It will look at the extent of shapefiles to decide if it needs to process features in a layer but that’s to be expected. I mean, if there’s nothing to draw then why bother. Have you verified that the layers render in a non-tiled setting?

I have tried commenting out the extents but still the same problem. I think it recognizes the inbuilt extents of the data layers.

From: mapserver-users [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Daniel Mwaurah Sent: Wednesday, December 23, 2015 2:27 PM To: [email protected]<mailto:[email protected]> Subject: [mapserver-users] CGI Tilemode blank on one layer hallo people, I would greatly appreciate some help with Mapserver Tile mode. Eeven a hint in the right direction would be much appreciated. I am trying to display two layers in Tile mode in open layers as follows 1. http://localhost/cgi-bin/mapserv?MAP=/var/wpsinput/gdss.map&layer=kenyaoutline&mode=tile&tile=${x}+${y}+${z}.png<http://localhost/cgi-bin/mapserv?MAP=/var/wpsinput/gdss.map&layer=kenyaoutline&mode=tile&tile=$%7bx%7d+$%7by%7d+$%7bz%7d.png> 2. http://localhost/cgi-bin/mapserv?MAP=/var/wpsinput/gdss.map&layer=10m_ocean&mode=tile&tile=${x}+${y}+${z}.png<http://localhost/cgi-bin/mapserv?MAP=/var/wpsinput/gdss.map&layer=10m_ocean&mode=tile&tile=$%7bx%7d+$%7by%7d+$%7bz%7d.png> The problem arises in that one layer the 10m_ocean displays while the other one just shows a blank. I suspect it has to do with the extents because the 10m_ocean layers has a large extent from -180 to 180 while the kenyaoutline layer only covers one country from about 33 to 37 degrees. Is there a limitation to small extents in tile mode? or what could be the problem. My mapfile is as below. MAP #FONTSET "[fontsetpath]" DEBUG 5 CONFIG "MS_ERRORFILE" "/var/www/wpsinput/ms_error.txt" EXTENT 33 -5 42 6 IMAGETYPE "png" NAME "Natural_Earth_quick_start_for_QGIS" SIZE 600 600 CONFIG ON_MISSING_DATA "LOG" STATUS ON UNITS DD OUTPUTFORMAT NAME "png" MIMETYPE "image/png" DRIVER "AGG/PNG" EXTENSION "png" IMAGEMODE RGBA TRANSPARENT TRUE END # OUTPUTFORMAT PROJECTION "proj=longlat" "datum=WGS84" "no_defs" END # PROJECTION LEGEND KEYSIZE 20 10 KEYSPACING 5 5 LABEL SIZE MEDIUM OFFSET 0 0 SHADOWSIZE 1 1 TYPE BITMAP END # LABEL STATUS OFF END # LEGEND QUERYMAP SIZE -1 -1 STATUS OFF STYLE HILITE END # QUERYMAP SCALEBAR INTERVALS 4 LABEL SIZE MEDIUM OFFSET 0 0 SHADOWSIZE 1 1 TYPE BITMAP END # LABEL SIZE 200 3 STATUS OFF UNITS MILES END # SCALEBAR WEB FOOTER "" HEADER "" TEMPPATH "" METADATA "ows_onlineresource" "http://localhost/cgi-bin/mapserv?map=/home/wpsinput/worldmap.map"; "ows_enable_request" "*" "ows_srs" "EPSG:4326" "ows_title" "Natural_Earth_quick_start_for_QGIS" END # METADATA #TEMPLATE "[templatepath]" END # WEB LAYER DATA "/var/www/10m_physical/10m_ocean.shp" EXTENT 33 -5 42 6 METADATA "ows_title" "10m_ocean" END # METADATA NAME "10m_ocean" PROJECTION "proj=longlat" "datum=WGS84" "no_defs" END # PROJECTION STATUS ON TILEITEM "location" TYPE POLYGON UNITS METERS CLASS NAME "Single symbol" STYLE COLOR 198 226 242 END # STYLE END # CLASS END # LAYER LAYER DATA "/var/www/kenyaoutline/Kenyaoutline.shp" EXTENT 33 -5 42 6 METADATA "ows_title" "Kenyaoutline" END # METADATA NAME "Kenyaoutline" PROJECTION "proj=longlat" "datum=WGS84" "no_defs" END # PROJECTION STATUS ON TILEITEM "location" TYPE POLYGON UNITS METERS CLASS NAME "Single symbol" STYLE COLOR 0 0 0 END # STYLE END # CLASS END # LAYER END # MAP The same happens when i try to view it using QGIS Tilelayer plugin. -- Kind regards, Mwaura Daniel -- Kind regards, Mwaura Daniel
