Hi,

Named classes appear in the legend and add least with CLASS-KEYIMAGE you can define the icon for the class.
LAYER
TYPE RASTER
?
CLASS
        NAME "TEST"
        KEYIMAGE "c:\ms4w_data\legend.png"

Subject: [mapserver-users] mapserv cli and run-time substitution
Message-ID: <CAHEdGZOqfaEN_5iSszCktG8GiiDhuM8afi=MjCLHiKdTvHaB6w@mail.gmail.com>

Hi,
I have this map file [1] in which I use this simple class expression
"EXPRESSION ([year] < 1976)".
Starting from it, I'm able to create the png output I want, running:

mapserv -nh "QUERY_STRING=map=data.map&mode=map" >out.png

But if I replace the hard coded year value with '%year%', and then I run
this command

mapserv -nh "QUERY_STRING=map=data.map&mode=map&year=1976" >out.png

I have a wrong PNG output, in which the layer that has the run-time
substitution variable is not rendered properly, because it seems that the
value is not collected.

What's wrong with my steps? How to use run-time substitution via cli?

Thank you,

Andrea

Hmmmm... Looks right to me. Will need to run a test locally and report back.

Hi Steve,
and thank you.

It seems right also to me.
Moreover there is a related paragraph in the documentation:
https://mapserver.org/el/mapfile/validation.html#test-with-commandline

I want to add that I'm using MapServer version 7.6.2

Hi,

Shouldn't the variable be wrapped in percentage signs?

EXPRESSION (%year% < 1976)

my goal is another one. My hardcorded expression is "EXPRESSION ([year] <
1976)".

I want to use run-time substitution to use "EXPRESSION ([year] < '%year%')",
in the same way described here:
https://mapserver.org/el/mapfile/validation.html#test-with-commandline

Thank you

Ah ok I was looking at the mapfile. Passing &YEAR=1976 in from the command line should work fine.
Maybe the value is being treated as a string, so you could test if the following worked (equals rather than less than):

EXPRESSION ("[year]" = "%year%")

Also maybe try with a different parameter name e.g. MYYEAR just in case YEAR is treated differently as it is used for various OGC services.

Hi Seth,

This works, but there are some points that seem strange to me:

- if in the map file I set "[year] < 1976", it works. Than year is a number;
- my layer source is a virtual file, a CSV, in which I set "<Field
name="year" src="year" type="integer"/>"

So why do I have to set it as a string, if it is already set as a number
and if it works as a number when I do not use run-time substitution?
My files are in this compressed one:
https://github.com/aborruso/blackboard/blob/gh-pages/trash/processing.7z

Best regards

So does the following also work? Without quotes should mean it is treated as a number:

EXPRESSION ([year] = %year%)

This should be the way to do it. No quotes around %year% in either
expression.

Thanks Andrea, I have added your working example to the documentation, 
and included the step of checking your data type through an ogrinfo 
command.  Thanks again. https://mapserver.org/mapfile/validation.html

Hi there!

Trying to use a geojson output from API directly in Mapserver layer.
Geojson is per standard, 4326, but my Mapserver and OL (the client) is
configured to 3301.
We have hundreds of layers (mostly from Postgres) at the same time and the
system works.
No other direct API ones.

The current MAP file's WEB part looks like this:

 Couple of questions I have which I didnt really find answers for:


   1. Had issues with 4326 to 3301 transformation,the extent and all that.
   (OpenLayers could manage but QGIS couldnt). Previously only had ows_extent.
   Is ows_extent even a thing? This only shows wms_extent
   https://mapserver.org/ogc/wms_server.html#layer-object-metadata
   Should you use wfs_extent and wms_extent instead?
   2. My layer is doing an OGR connection directly to the API URL. Works
   fine. My question is, the API renews itself every 2 minutes (new data).
   How does Mapserver handle the request with that connection? I move the
   map (openlayers), there's a new Mapserver request - does Mapserver make a
   new request to the API endpoint and get a new json?
   Or is there some sort of cache?
   3. Am I missing something else from the Metadata that I should consider?


With kind regards,
Sander

Hi,

About ows_* from https://www.mapserver.org/ogc/wms_server.html

(Note that each of the metadata below can also be referred to as ?ows_*? instead of ?wms_*?. MapServer tries the ?wms_*? metadata first, and if not found it tries the corresponding ?ows_*? name. Using this reduces the amount of duplication in mapfiles that support multiple OGC interfaces since ?ows_*? metadata can be used almost everywhere for common metadata items shared by multiple OGC interfaces.)

the wms_ / wfs_ / ows_ / oga_ (coming in MapServer 8) Metadata-entry are 
aiming on your output. So, if you only want to serve wms, you only need 
the wms_*.
wfs_* conigures your WFS-server. If you want to serv wms and wfs and the 
parameters are the same, you can use ows_ instead.

No cache by default. MapServer requests the data source every time 
mapserver gets itself a getmap or get feature info request (or 
getfeature when serving wfs). So your WMS serves the actual data any 
time. If you want a cache, you have to configure mapcache or mapproxy 
separately.

I don't see anything missing

Subject: [mapserver-users] Mapcache disk cache gives unexpected paths to
 tiles
Message-ID: <ccec47bff82474f4ac8b79a103d58b96@aspenes.priv.no>

Hi

I have a mapcache running using disk as cache method with config like 
this:

     <cache name="disk" type="disk">
         <base>/mapcache</base>
         
<template>/mapcache/{tileset}#{grid}#{dim}/{z}/{x}/{y}.{ext}</template>
     </cache>

But here is what I get on disk:

/mapcache/<my tileset 
name>/EPSG:3857/2022-02-05T00:12:00Z/05/000/000/038/000/000/043.png

What I don't understand is below the zoom level (here 05) I get 000 
followed by 000. Then the y followed by another double 000 before I get 
the x with my extension.

Where does all these 000 sub directories comes from and what functions 
do they have?

I don't think this affects the performance, but this must cause creating 
thousands and thousands of unnecessary sub directories?

Thanks.

Trygve

You should remove the <base>/mapcache</base> from the >cache> block, as it
takes precedence over your <template>

All,



Had a light turnout last month, but the show must go on.



Michael Talbot will be presenting at our next OSGeo Local Chapter meeting on an ?Introduction to Cloud Optimzied GeoTIFFs?



Mike is a water resources engineer at Emmons & Olivier Resources, Inc. (EOR), where he wears many hats. One of those hats is as a full stack web developer and manager of EOR's cloud infrastructure and PostgreSQL databases.

Ah, thanks Thomas!

I did not catch that from the documentation.
I also needed to add layout like this:

     <cache name="disk" type="disk" layout="template">
         
<template>/mapcache/{tileset}/{grid}/{dim:time}/{z}/{x}/{y}.{ext}</template>
     </cache>

to make it work ( both from testing and looking at the documentation)

If you use the default this will be like tilecache as far as I 
understand.

Do you have any idea what will be the fastest? To use default like:
     <cache name="disk2" type="disk">
         <base>/mapcache</base>
     </cache>

or the solution above with template? ( As a lot of 000 directories will 
be created with the base one)

All,



Had a really good meeting this evening.    Michael Talbot presented  on an ?Introduction to Cloud Optimzied GeoTIFFs?.  The recording has been post to the Local OSGeo Chapter page below.



Casting out for presenters for next Month on March 9th.   Anyone, anyone?

Subject: [mapserver-users] Fwd: Why TileMode generates different display
 effect of WMS with the same map file?
In-Reply-To: <CA+XOF9MZV+jqnRio42TXdffFBhoxhujeHwRL9N6+oEK4tdU=Wg@mail.gmail.com>
References: <CA+XOF9MZV+jqnRio42TXdffFBhoxhujeHwRL9N6+oEK4tdU=Wg@mail.gmail.com>
Message-ID: <CA+XOF9NNHeLKCZ+5JQ-_8h0U_ytsQvTbCAT7x434k2FWRuiK7Q@mail.gmail.com>

Hi, I use the same map file to serve WMS and TileMode request. The style
part in it is very simple:

>   CLASS
>       NAME       "highway"
>       STYLE
>         COLOR        0 0 0
>         WIDTH        1
>       END
>     END
>
 But MapServer 7.6.4 generate different display effect for TileMode and WMS
respectively. I also changed the WIDTH to 6 and it does not help. I have
attached screenshots for comparison.
 How can I get almost the same display effect in these two modes?

Try OUTLINEWIDTH instead of WIDTH

Are vector tiles supported and documented? My searches only find RFC 119.

Subject: [mapserver-users] How to display different features in different
 map scale ranges?
Message-ID: <CA+XOF9M4o4GWHxh2sv7Aoi5civuU2U=dfpDZABC6n+Po5wkD8w@mail.gmail.com>

Hi, I would like to find a way to display different features in different
map scale ranges, but some features may be displayed in multiple scale
ranges. I know that CLASS can set EXPRESSION, MINSCALEDENOM and
MAXSCALEDENOM, it seems that using multiple CLASS does the trick. When a
Feature matches the expression of a CLASS but the scale range of the CLASS
is inconsistent with the current map, will MapServer continue to evaluate
whether the Feature belongs to other CLASS? Because if MapServer does not
continue to evaluate, this Feature cannot be displayed.

Or is there any other way to achieve what I want? Thanks.

OK, I missed this in documents:  The first class that matches the its
min/max scale constraints and its EXPRESSION
<https://www.mapserver.org/mapfile/expressions.html#expressions> check for
the current feature will be used for rendering.

Hi,

The code has been merged https://github.com/MapServer/MapServer/pull/5376
but as you can see in the PR the documentation page has never been created.
The demo code mentioned in the RFC works
https://mapserver.org/development/rfc/ms-rfc-119.html#bug-id-and-references

Hi, I know that MapServer will determine the CLASS of a Feature based on
the expression and scale range when drawing, but what if I want to avoid
reading data that is not needed under the current scale? FILTER can filter
LAYER data at the same time as spatial query, but do I have to create a
separate LAYER for each scale range?
Thanks.

Hi Kyle,

Take a look at LAYER SCALETOKEN - https://mapserver.org/mapfile/layer.html#mapfile-layer-scaletoken
and the RFC https://mapserver.org/development/rfc/ms-rfc-86.html#rfc86 

You should be able to add a filter directly to the DATA clause based on the scale that would filter the data directly at source.

I don't believe you can set a blurring (or sharpening) filter. However,
have a look at the layer composite feature (
https://mapserver.org/mapfile/composite.html), it might get you a
reasonable approximation of what you're looking for. --Steve

Hi everyone,

Short story:

Please add your company to the list of MapServer service providers, if 
you handle this type of work (see the related ticket at 
https://github.com/MapServer/MapServer-documentation/pull/674 )

Longer explanation:

It's time to give an update to the MapServer Service Providers page ( 
https://mapserver.org/community/service_providers.html ), as this helps 
provide an important resource for the community, for those looking for 
professional help.  The page lists professional service providers by 
Core Contributors, Contributors, and Other Service Providers; you can 
read about the background on these sections in the related RFC 
https://mapserver.org/development/rfc/ms-rfc-116.html

Please let me know if you would like to add your company.  You may wish 
to mention your addition in the related pull request for this at 
https://github.com/MapServer/MapServer-documentation/pull/674

I'll leave this ticket open for 10 business days, to hopefully give 
others a chance to add their company.

Thanks for making the MapServer community a vibrant place,

-jeff

Hi everyone!

Short story: please add your MapServer site or MapServer data services 
to the wiki page at 
https://github.com/MapServer/MapServer/wiki/MapServer-Site-Gallery

Background:

A few years ago a new MapServer user reminded us that we need working 
examples of applications (and MapServer-driven OGC/WMS/WFS/OWS services) 
listed on our map gallery. Please take a minute to add your site and 
specs (respecting the syntax and alphabetical order) at:
https://github.com/MapServer/MapServer/wiki/MapServer-Site-Gallery

It has become a great resource! Please take a moment to make sure that 
your MapServer-driven site or OGC services are listed there, especially 
as we are getting closer to the big MapServer 8.0 release. So help show 
the powers of MapServer!!

Thanks for making the MapServer community a vibrant place,

The only problem that I'm struggling with is (I think) an OpenLayers issue.
I want to do vector tiles in state plane coordinates, not epsg:3857. AFAIK
only t-rex and mapserver can serve non epsg:3857 vector tiles.

But more generally, I think that advertising that mapserver can serve
vector tiles might be nice. An RFC with no voting history doesn't inspire
great confidence in a pretty great feature.

Hi Rich,

Good catch, if you file a ticket for this in the docs repository I will 
tackle: https://github.com/MapServer/MapServer-documentation/issues

(for Windows users, MS4W includes the MVT demo, but you make a good 
point, and more could be setup for users out-of-the-box, I will tackle 
this for the MS4W 5.0-final release: https://ms4w.com/trac/ticket/369 )

Subject: [mapserver-users] Need example of Halo effect around features.
Message-ID: <FF813F06-2678-47CB-AF19-5BE19E33CA77@ci.stpaul.mn.us>

All,

Is there an example of adding a halo effect around features, points, lines, polygons . . .   Also I need it to be applied to scale if possible (map units), which may sound a bit weird as a requirement . . .  I looked at the COMPOSITE stuff a little, and I would need to experiment some there to see what does and how.

Thanks

Bobb

Hi,

I have made an example about the layer Composition pipeline, since there are some missing information in the documentation.

https://gist.github.com/LarsSchy/4aa75fd2a6bc7eb01a7cff9beb64b59a
The mapfile in the GIST shows how to use the Composition pipeline. The examples are based on what Thomas B. has described on the users-list in the past.
In addition to that I have added examples with a line and a point symbol.

Have fun / Lars Schylberg

 Mapfile?
Message-ID: <690C8D12-3B81-47CA-970C-E1E0179B2FDA@ci.stpaul.mn.us>

Hello,

Anyone tried drawing Dimensions (just need a way to dimension between two points right now), with perpendicular offset leaders, etc.

Just got the idea from looking at Mapfile that Lars sent me here, that uses TRANSLATE inside of a COMPOSITE block, not really clear to me at the moment how to draw the extensions lines though, maybe a zero length solid translate . . .  hmmm.

Thanks  Lars, now you have me sidetracked . . .  :c)

Subject: [mapserver-users] Issue - Style constantly changes using Mapserver
 7.6
Message-ID: <YQXPR01MB51722BCCEEAA6171181D9B8CCD3E9@YQXPR01MB5172.CANPRD01.PROD.OUTLOOK.COM>

Hi,

I am currently using GDAL 3.1.3 and Mapserver 7.6.2 on a Ubuntu machine. I created a layer using a GRIB2 file as the source data.

When I tested the layer on QGIS 3.20, I noticed that it does not output correctly. When I'm zooming or moving the viewing extent to visualize the layer or data, the style constantly changes. I tested with WMS GetMap requests through a browser and the output issue is still there. See example GIF here: https://pasteboard.co/wAmyAUDyEeZs.gif

I validated the different classes (CLASS) in the style used in the mapfile and everything seems to be in order. From what I understand, Mapserver seems to do some interpolation, but I can't quite understand how it affects the output on that scale. I investigated and checked if the source file was the issue, but from what I see it doesn't seem like it's the case, as I tested with other data from another source file in NetCDF, and the issue is still there.

I created a test case to show you the issue here:


?       Sample mapfile: https://pastebin.com/KC3UkR4m


?       GRIB2 Source file (available here: https://dd.weather.gc.ca/model_hrdps/continental/grib2/00/001/) for the source data (using following patterns) : /CMC_hrdps_continental_PTYPE_SFC_0_ps2.5km_*.grib2/

Do you have an idea what could be the issue or how the interpolation works, and how to solve this issue?

Thanks a lot in advance for your answer(s)!

 already in proj.db
Message-ID: <74d8fb1ef2f64c54ac1a0ac7db746a60@co.lyon.mn.us>

Hello,

I am having trouble trying to reference ESRI authority coordinate systems that are within proj.db within MapServer.   I know this should work because I can use the QGIS can use the ESRI authority coordinate systems and QGIS apparently uses the same proj.db database as MapServer.  I tried referencing the projection using init=esri:103749 and init=epsg 103749.  Neither option appears to work.  I can however manually and the projection parameters.

Here is a snippet of my code:
MAP
PROJECTION
"init=epsg:4326"
END  #Map Projection
LAYER
PROJECTION
#WORKS
"+proj=lcc +lat_1=44.25 +lat_2=44.58333333333334 +lat_0=44.19555555555555 +lon_0=-95.85000000000001 +x_0=152400.3048006096 +y_0=30480.06096012192 +a=6378559.758 + b=6357173.65471281 +units=ft +no_defs  <>"
#Does not work
"init=esri:103749"
"init=esri:103749"
                                End  #Layer projection
                END #Layer
END #Map

Please let me know if you have any thoughts regarding how we can use ESRI authority projections.

Thank You

A tweak in MapServer code would be required to accept syntax like 
"ESRI:XXXXX". The +init=epsg: stuff that is a compatibility syntax which 
only works for EPSG.

Hi Felix,

I have tested your case here locally on Windows with MS4W (this will be 
MS4W 5.0-beta3, that contains GDAL 3.4.1, MapServer 8.0dev, PROJ 8.2.1 etc).

I have used one of those GRIB2 files ( 
https://dd.weather.gc.ca/model_hrdps/continental/grib2/00/001/CMC_hrdps_continental_PTYPE_SFC_0_ps2.5km_2022022500_P001-00.grib2 
) and created a WMS service through MS4W, and then used QGIS 3.24 to add 
the WMS service, and zoomed-in 3 times : see the animated gif at 
https://pasteboard.co/N9LZcB9Nfgpc.gif

I don't see your issue.

Could you pick one GRIB2 file (the one that is shown in the extents of 
your image) and change your mapfile to use that single data file (no 
patterns) and reproduce your issue?

If yes, let us know here the exact filename that is shown in your image 
(and the exact extents to use).

Have a nice weekend,

-jeff

Maybe my test does show it a little (the brown "rain-snow" area to the 
left of my mouse, on top of the "rain" green area), as the resampling 
happens as you zoom-in.

Subject: [mapserver-users] How to limit the width of the outline when the
 symbol size changes with the map scale?
Message-ID: <CA+XOF9OT2rOZGFpEMGQgMcascfC3HZeG1kK9uww0tas1K1ijtw@mail.gmail.com>

Hi, when I set up a map for points, I use SYMBOLSCALEDENOM to change
the size of points and MIN/MAXSIZE to limit it, but there seems to be no
way to control the width of the outline of points. The outline seems to
keep getting bigger as the map zooms in. The image below is the result map
as the map zooms in:
https://pasteboard.co/JC19o7caYHHk.png
Is there any way to solve this problem?
In addition, it seems that there is no way to set the transparency of the
outline separately. Is it necessary to use a separate STYLE to implement it
with GEOMTRANSFORM?
Thanks.

Hi,

Have you tried to use two filled circle symbols for making the outline effect, one below and the other one above? Or to use png image as a symbol?

You can also play with the various PROCESSING directives for raster 
layers to see if that helps: 
https://mapserver.org/input/raster.html#special-processing-directives 
(RESAMPLE, LOAD_FULL_RES_IMAGE, ...)

Hi,

Just a quick example. Please look at the GIST I created.

https://gist.github.com/LarsSchy/610fc4cf3ed91ba0113b3c215481615b
Jukka is right two circle symbols on top of each other i possible the best solution. That is circle 3, 4 and 5.
In circle 2 I am drawing the outline first and then the middle. It is kind the same.
Circle 4 and 5 I am drawing the red outline with translucent color: COLOR "#FF000080"
Circle 5 is with a shadow with color "#80808080". That is grey with 50 % transparency.
The 80 is 128 in hex.

Run the example with: shp2img -m point_examples.map -o point_examples.png
My MapServer version this evening was: MapServer version 7.2.2

I guess that these should behave differently when You zoom.

Have fun / Lars Schylberg

Hi Jeff,

Thanks for your answer! I did try multiple PROCESSING directives like LOAD_FULL_RES_IMAGE and LOAD_WHOLE_IMAGE but the issue is still there unfortunately (unless I missed a important directive).

For the purpose of investigation, I've put the same mapfile with a different DATA pointing to a specific GRIB2 like you asked (mapfile available here: https://pastebin.com/AHnzpCz6). The GRIB2 file is available to download here: https://dd.weather.gc.ca/model_hrdps/continental/grib2/00/001/CMC_hrdps_continental_PTYPE_SFC_0_ps2.5km_2022022800_P001-00.grib2
 
I can see the issue on QGIS with the extent "-89.52, 33.63, -42.32, 56.52" and zooming 1 or 2 times after (to the "-74.71, 37.78, -51.16, 49.24" extent for example). Here is a visual example (GIF) with this GRIB2 file on those extents: https://pasteboard.co/hQr1ukpIczI5.gif

Hope this new mapfile and GRIB2 file helps spotting the issue on your side. It seems this issue is there on all GRIB2 files following the " /CMC_hrdps_continental_PTYPE_SFC_0_ps2.5km_*.grib2/ " pattern (when zooming a lot, we see the green and orange changing constantly).

Thanks a lot in advance for your help!

You can also play with the various PROCESSING directives for raster layers to see if that helps:

All,

Next (second) Wed. is our next Chapter meeting.  Just casting out for a presenter.

I can handle setting up the presentation and recording duties.  Just need someone to do the presenting.  Can be anything Geo-related.

Thanks
