Re: [mapserver-users] Dynamic symbols
Hej Lars, Thanks for your help. I have tried method 1 to produce bars and pies successfully, and it helped me a lot. But it would be nice to be able to construct any type of graphics and place them on polygons to visualize some feature. Can you do that with your SQL method?

These can then be used "on the fly" within mapserver or for preprossing of the data. I could show some examples if any one is interested.

Re: [mapserver-users] Polygon border with marker line symbol
Hi, Jukka R, I would love to learn how to prevent polygon borders to be drawn twice.

Because of that rendering with sparse symbols may look ugly. I would consider preprocessing the data so that you will have a clean line data where duplicate sections of the borders have been removed for rendering the borders and polygon layer for the rest. -Jukka Rahkonen- Lähettäjä:mapserver-users [mailto:mapserver-users-boun...@lists.osgeo.org] PuolestaAnton Bakker Lähetetty: 12. lokakuuta 2017 11:55 Vastaanottaja: lars.schylb...@blixtmail.se Kopio: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Polygon border with marker line symbol Hi Lars, On second thought setting the TYPE to LINE does not fit my usecase exactly. I would like to achieve the following for a polygon layer: https://i.imgur.com/3stwHw4.png [https://i.imgur.com/3stwHw4.png] . So the two requirements for the symbology are: - Marker line symbol on border - Polygon fill With setting the type to line I can only achieve the marker line symbol, but I cannot specify a fill: https://i.imgur.com/tk6vJ4b.png [https://i.imgur.com/tk6vJ4b.png] . Do you know if there is a way of achieving this effect? I guess it maybe could be done by grouping two layers, together and treating them as one, but preferably the solution is restricted to one layer.

[mapserver-users] Issue with label offset
We are using different mapfiles for different users and sometimes over the same geographical area. Funny thing is that in one of the cases where two mapfiles cover the same area a label for a line works ok in mapfile A but not in mapfile B despite the fact that the label code for one particular line feature is identical in the two mapfiles. I have traced this to OFFSET. OFFSET 3 99 works in mapfile A but gives Error 500 Internal Server Error in mapfile B. On the other hand OFFSET 1 99 and -2 99 works fine in mapfile B. The two mapfiles use different epsg and have different scale levels and as far as I can see that is the only thing that differs. I can contribute with more data if anyone will dig into this.

Re: [mapserver-users] Road shields on Mapserver 7
Interesting discussion!
I have an issue with geotransform 'labelpnt' I so far have failed to solve.
Consider a line that depicts a creek. Sometimes it is important to show the
direction of flow. That is mostly achieved on maps by placing arrows along
the creek showing which way the water flows.
I have tried to use LABEL and GEOMTRANSFORM 'labelpoint' with an arrow
symbol and where the label has no text but has REPEATDISTANCE and ANGLE.
Problem is that the symbol is not affected by ANGLE ( neither FOLLOW, AUTO
or AUTO2 ). Does anybody know how to rotate labelpoint symbols or is it not
possible?.
Plan B is to use a LABEL with TEXT = ">" which works fine but is not that
elegant.

Hi,
I more detail in my previous example the offset in the style block is
because the example is part of a block with three road shields stacked.

One single shield would be like this:

Hi,
This is how I do it in MS7.0. This is just part of the class with the first
two labels. I have different shield depending on the number of digits.
I also have different color depending on the color of the shield. This is
following European road label standard.

[mapserver-users] Georef output
Hi, I am trying to get georeferenced maps from Mapserver. For geoTiff the maps get georeferenced allright but gdalinfo shows that there is no data under 'Coordinate system is:'. The epsg is set in the mapfile but does not seem to get passed to the gTiff driver. How can I fix that? For geoPDF ( using CAIRO ) neither extents nor coordinate system are added to the output file.
