Re: [MapServer-users] getting incomplete parts of a geometry

In your .map file try setting:

PROCESSING "POLYLINE_NO_CLIP=True"

Hi,

The client is making tiled requests like this:

This tile contains most part of the parcel. What might happen is that when the client is asking for the next tile to the left, then the BBOX is partially outside the EXTENT that you have configured for the layer. Maybe Mapserver considers that the request is off-site and does not render anything. Make your extent bigger or comment it out altogether. Also check the extent at the MAP level. It should cover the whole area where you possibly have data.

Hi,

That I don't know, but I'll check tomorrow with my colleague that is doing the front-end.

The URL is https://ibm.wur.nl/ <https://ibm.wur.nl/> and the Basemap and the layer is Food_Forest.

    Hi,

    How about the client, what is the BBOX that it is using in the WMS
    GetMap request that it creates?

    Hi Jukka,

    Thanks for your email. I got the extent from the geometry it self.
    Like so:

       ogrinfo PG:"host=pxxxxx port=5432 dbname=pxxxxx user=pxxxxx"
    ibm.food_forest -summary

       INFO: Open of `PG:host=pxxxxx port=5432 dbname=pxxxxx user=pxxxxx'

             using driver `PostgreSQL' successful.

       Layer name: ibm.food_forest

       Geometry: Polygon

       Feature Count: 1

       Extent: (194914.000000, 420110.000000) - (195152.000000,
    420307.000000)

    (...)

        Hi,

        Does the rendered part perhaps match with the extent that you
        have configured for the layer “EXTENT 194914 420110 195152 420307”?

        Hi all,


        I'm using Mapserver 8.0 and I'm getting incomplete parts of a
        geometry, either if is TYPE LINE or POLYGON. Please, see
        pictures https://pasteboard.co/ToPTZ6OnjPaJ.png
        <https://pasteboard.co/ToPTZ6OnjPaJ.png>.
        I wonder if I'm missing something in the mapfile. The LAYER part
        of the mapfile looks like this:

        /  LAYER/

        /      TEMPLATE "XXXXX.tmpl"/

        /      NAME "Food_Forest"/

        /      STATUS ON/

        /      TYPE *LINE*/

        /      PROJECTION #source/

        /        "init=epsg:28992"/

        /      END # PROJECTION/

        /      CONNECTIONTYPE POSTGIS/

        /      CONNECTION "host=XXXXX port=XXXXX dbname=XXXXX user=XXXXX
        password=XXXXX"/

        /      DATA "geom FROM XXXXX.XXXXX USING UNIQUE XXXXX_id USING
        srid=28992"/

        /      EXTENT 194914 420110 195152 420307/

        /      PROCESSING "CLOSE_CONNECTION=DEFER"/

        /      CLASS/

        /        NAME "Food_Forest"/

        /        STYLE/

        /          COLOR 255 0 0/

        /          OUTLINEWIDTH 1/

        /        END # STYLE/

        /      END # CLASS/

        /  END # LAYER/


        Thanks!

        Cheers,

        Eloi
