[MapServer-users] Creating UTF grids with MapServer and MapCache

[karsten]

Yes that worked now to restart Apache ! 
 
Here is the final config snippets in case it helps someone 
and remember the format tags aka 'MVT' are case sensitive ;)
 
mapfile
OUTPUTFORMAT
   NAME "MVT"
   DRIVER MVT
   FORMATOPTION "EDGE_BUFFER=10"
END
 
LAYER 
    ....
    # added:
    UTFITEM   "gml_id"   
    UTFDATA
"{\"gml_id\":\"[gml_id]\",\"fkz\":\"[flurstueckskennzeichen]\",\"gemeindenam
e\":\"[gemeindename]\",\"Gemarkungsname\":\"[Gemarkungsname]\",\"zaehler\":\
"[zaehler]\",\"nenner\":\"[nenner]\"}" 
END

mapcache.xml
 
   <format name="MVT" type="RAW"> 
     <extension>mvt</extension>
     <mime_type>application/vnd.mapbox-vector-tile</mime_type>
   </format>
 
   <source name="flurst_utf" type="wms">
      <getmap>
         <params>
            <FORMAT>MVT</FORMAT>
            <LAYERS>flurst_gff</LAYERS>
            <MAP>/xyz/utfgrid.map</MAP>
         </params>
      </getmap>
      <http>
         <url>http://theurl/cgi-bin/mapserv</url>
      </http>
   </source>
 
   <tileset name="flurst_utf_tiles">
      <metadata>
         <title>Flurst UTF</title>
         <abstract>Flurst UTF</abstract>
      </metadata>
      <source>flurst_utf</source>
      <cache>disk</cache>
      <grid restricted_extent="727077.513504722 6536256.08499261
754566.10585149 6562363.18993406">GoogleMapsCompatible</grid>
      <format>MVT</format>
    </tileset>

Oh yes that could be the problem, so far I have
 
OUTPUTFORMAT
  NAME "utfgrid" 
  DRIVER UTFGRID
  MIMETYPE "application/json" 
  EXTENSION "json" 
  FORMATOPTION "UTFRESOLUTION=4" 
  FORMATOPTION "DUPLICATES=false" 
END
 
will try with mvt now (goal is to create utfgrid json though)

Thanks Scott,
 
I do have a tileset like this below
 
  <tileset name="flurst_utf_tiles">
      <metadata>
         <title>Flurst UTF</title>
         <abstract>Flurst UTF</abstract>
      </metadata>
      <source>flurst_utf</source>
      <cache>disk</cache>
      <grid restricted_extent="727077.513504722 6536256.08499261
754566.10585149 6562363.18993406">GoogleMapsCompatible</grid>
      <format>mvt</format>
      <metatile>5 5</metatile>
      <metabuffer>10</metabuffer>
      <expires>3600</expires>
    </tileset>
 
but also with this get the error
 
tileset "flurst_utf_tiles" references format "mvt", but it is not configured

Hi All,
 
I am working on a correct configuration to cerate UTFGrid json tiles  via
MapCache and MapServer to seed a json tile set 
 
MapCache is up and running on my ubuntu 20 server and WMS requests (PNG,
Jpeg ) are working as is the seeding utility.
Now I am trying to add a UTFGrid tile layer and added the mvt format into
the (working for the other layers correctly) mapcache.xml:
   <format name="MVT" type="RAW"> 
     <extension>mvt</extension>
     <mime_type>application/vnd.mapbox-vector-tile</mime_type>
   </format>
the layer is
   <source name="flurst_utf" type="wms">
      <getmap>
         <params>
            <FORMAT>mvt</FORMAT>
            <LAYERS>flurst</LAYERS>
            <MAP>/var/mapdata/utfgrid.map</MAP>
         </params>
      </getmap>
      <http>
         <url>http://myserver/cgi-bin/mapserv</url>
      </http>
   </source>
When tryign to restrart apache however I get this error message 
systemctl status apache2.service
● apache2.service - The Apache HTTP Server
     Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor
preset: enabled)

references format "mvt", but it is not configured
Sep 07 20:31:58 terraz apachectl[1265907]: Action 'start' failed.

What am I missing here ?
Thanks
