Subject: [MapServer-users] Possible issue between MapCache WMTS,
the new ArcGIS Online Viewer, and the Web App Builder
Message-ID: <5ca4c64eabda4002b9dbb0b56c5d24b0@co.lyon.mn.us>
Hello,
I noticed that MapCache WMTS basemaps do not display in ESRI's Web Application Builder when I create the map in the "New Map Viewer." However, if I create the map with "Map Viewer Classic" then the tiles appear appropriately in the Web Application Builder. ESRI thinks that this is a possible bug on their end, but it also could be a misconfiguration on my end as well.
Questions and thoughts:
1. If other people are having this issue then please try using the Map Viewer Classic and has anyone had success with the new map viewer?
2. Please let me know if my configuration below looks appropriate.
3. ESRI asked if I would like to continue debugging this issue. Would any of the developers want to be included in this discussion?
Thanks!

Subject: [MapServer-users] converting an expression to an OGC filter
Message-ID:
I currently have an expression in my mapfile EXPRESSION ('[postcode]' ~*
'0..$') and I'm in the process of moving to using SLD for styling - I
thought I could convert that expression to
postcode
.*0..
Which I think should match from the start of the string (.*) to a 0
and then two characters (..) to the end of the string. But it doesn't
work - neither does any variant on this work either.
Is there some issue with conversions between SLD Filters and internal
expressions that I'm missing or is there something else I should know
about LIKE filters?
Thanks
Ian

It's a postgis database on the backend, the original expression works fine
but not when it's input as an OGC expression.

Your pattern seems to be wrong. You originally used a case insensitive regex 0..$ meaning a value shall end with a '0' and to other arbitrary characters. Your PropertyIsLike filter is translated into an SQL "like": (for Postgres)
postcode::text ilike '_%0__'
meaning a string as a whole shall consist of an arbitrary character followed by zero or more arbitrary characters followed by a '0' and two additional arbitrary characters. The corresponding regex would look like ^..*0..$
So I guess you would like want to use *0.. as pattern:
postcode
*0..

Subject: [MapServer-users] Mapserver on k8s weird behaviour
Message-ID:
Hello,
I am using Mapserver on Kubernetes (LoadBalancer). Everything works great - GetMap, GetCapabilities, layers load correctly in QGIS and Leaflet.
However, what caught my attention is that when passing the mapfile's url using LoadBalancer/Kubernetes IP, only the first time the message is
msLoadMap(): Regular expression error. MS_DEFAULT_MAPFILE_PATTERN validation failed
and every time thereafter
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
By refreshing a few times, you may get the expected message again, but this is random. As I mentioned - layers and requests load correctly everywhere (also after repeated refreshing). Should I be concerned? I would love to understand why is this happening ^^
Sample mapfile (but problem occured on all those tested):

Based on that error message you're not running MapServer 8.0 though. That was an area that changed between v.7 and v.8 and the error message was updated. V.8 outputs something like:

Subject: [MapServer-users] Problems with vrt created from GCP raster
Message-ID:
Hello,
up to now, I have been working with VRT as a carrier for the rasters I wanted to use in the mapfile. Now in order to use the rasters that were provided to me (they are GCP georeferenced rasters) I have to convert them to VRT (via gdal warp), hence my question - how can I mosaic the rasters within one layer in Mapserver (one layer = one day of photos from Sentinel-2 for example). I can't create vrt to existing vrt, and creating a tileindex for each layer generates too many files. I wanted to create one vrt gathering together all of raster but gdal_warp uses only the first one as data source.
What can I do?
Best regards,
Marcin

Next, in your .map file use runtime substitution:
DATA "/file/path/Day%day%.vrt"
If you really want to make this fast, convert all your source .tif's to

1. gdalbuildvrt doesnt work with raster georeferenced by ground control points. Thats why I am using gdal warp -> https://gis.stackexchange.com/questions/283595/transform-rectify-unprojected-raster-using-target-extent-co-ordinates
2. Source files are already in cloud optimized format

The only thing I can think of is create an entirely new .tif from your
gcp .tif, then it shouldn't be a problem.
However, this could result a very large set of new sentinel tifs. Bad.

Subject: [MapServer-users] How do I use an SQL query in a Postgis tileindex
of vector files?
Message-ID:
Hi,
How do I get a tileindex of vector files working from data in a Postgis
database and accessed via an SQL query of my choosing?
I would like to make a vector tile index as described at
https://mapserver.org/optimization/vector.html#index-your-data using data
stored in a Postgis database and a SQL query of my choosing. Here is one
approach that works:
1. create a test table in postgres database:
> create table testtable (id int, location text, geom
geometry(Polygon,4326));
2. insert data into the table:
insert into testtable (id, location, geom) values (1,
'/test_data/test.geojson,0', 'POLYGON((122.01377475333321
29.96355712017804,122.01424752183958 29.915620560607106,122.06927507957919
29.91602043815968,122.0688286928125 29.963957768165944,122.01377475333321
29.96355712017804))'::geometry);
3. Define a layer using the OGR connection:
LAYER
NAME "vector"
TYPE POLYGON
CONNECTIONTYPE OGR
CONNECTION "PG:\"host=localhost user=postgres dbname=mydatabase
password=mypwd tables=testtable(geom)\""
STATUS OFF
CLASS
STYLE
WIDTH 1
OUTLINECOLOR 255 105 180
END
END
END
4. Issue a request:
mapserv
QUERY_STRING='SERVICE=WMS&map=/tmpp/mapfile.map&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image/png&layers=vector&width=256&height=256&crs=EPSG:3857&bbox=13580108.193257555,3487974.474709164,13585000.163067807,3492866.4445194146'
and I get an image of my vectors back.
How do I use a more complex query than `testtable(geom)`? I tried
specifying a query via a DATA block:
LAYER
NAME "vector"
TYPE POLYGON
CONNECTIONTYPE OGR
CONNECTION "PG:\"host=localhost user=postgres dbname=mydatabase
password=mypwd\""
DATA "geom FROM (SELECT
id,
geom,
location
FROM testtable
) AS subquery USING unique id USING SRID=4326"
PROJECTION
"init=epsg:4326"
END
STATUS OFF
CLASS
STYLE
WIDTH 1
OUTLINECOLOR 255 105 180
END
END
END
However, the same query generates an error:
mapserv
QUERY_STRING='SERVICE=WMS&map=/tmpp/mapfile.map&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image/png&layers=vector&width=256&height=256&crs=EPSG:3857&bbox=13580108.193257555,3487974.474709164,13585000.163067807,3492866.4445194146'
"msOGRFileOpen(): OGR error. Open failed for OGR connection in layer
`vector'. File not found or unsupported format. Check server logs.
msDrawMap(): Image handling error. Failed to draw layer named 'vector'"
I tried using a postgis connectiontype, but could not get that working
either https://mapserver.org/mapfile/layer.html#mapfile-layer-connectiontype
How do I get a tileindex of vector files working from data in a Postgis
database and accessed via an SQL query of my choosing?
Thanks!
Pete

Subject: [MapServer-users] WFS output geojson - missing column with null
values
Message-ID:
I runmapserver7.6.4 compiled with gdal 3.2.1.
When I output various formats (CSV/KML/GPKG) from my layer (gpkg based), the requested features are properly returned.
In the case of an ogroutput in geojson format, some of mycolumns are not returned.The missing column are those with null values.
Here myOUTPUTFORMAT definition
#==============================================
END
OUTPUTFORMAT
NAME "geojson"
DRIVER "OGR/GEOJSON"
FORMATOPTION "LCO:COORDINATE_PRECISION=15"
FORMATOPTION "LCO:WRITE_BBOX=YES"
FORMATOPTION "STORAGE=memory"
FORMATOPTION "FORM=simple"
FORMATOPTION "USE_FEATUREID=true"
FORMATOPTION "FILENAME=%outfile%.geojson"
MIMETYPE "application/geo+json"
#===============================================
I've tested with these 2 additionnal properties without any success....FORMATOPTION "LCO:WRITE_NON_FINITE_VALUES=YES"
FORMATOPTION "LCO:RFC7946=YES"
i've also tried with
gml_types auto
or
gml_val_cam_annee_1 Character (or Real) without success.
Here 2 links with the current issue.
- wfs output (geojson) with missing column --> https://ws.mapserver.transports.gouv.qc.ca/swtq?outfile=requestedColumnIsMissing&service=wfs&version=2.0.0&request=getfeature&typename=ms:circulation_routier&outputformat=geojson&srsname=EPSG:4326&count=1&propertyName=val_cam_annee_1
- wfs output (kml) with requested column --> https://ws.mapserver.transports.gouv.qc.ca/swtq?outfile=requestedcolumIsPresent&service=wfs&version=2.0.0&request=getfeature&typename=ms:circulation_routier&outputformat=kml&srsname=EPSG:4326&count=1&propertyName=val_cam_annee_1
I've found a workaround, I declare a sql syntax with a coalesce(field,'') ... but I look for a proper fix.
I will probably push this fix on december 7. Here the getfeature responses:
-
circulation_routier
.....
- {

Subject: [MapServer-users] Vector tileindex with connectiontype OGR
Message-ID:
Hi,
How do I get a vector tileindex working with another Mapserver layer as the
tileindex?
I have the following tindex.geojson:
{
"type":"FeatureCollection","features":[{"type":"Feature","properties":{"location":"/app/mapfiles/test.geojson"},"geometry":{"type":"Polygon","coordinates":[[[122.013774753,29.96355712],[122.014247522,29.915620561],[122.06927508,29.916020438],[122.068828693,29.963957768],[122.013774753,29.96355712]]]}}]}
Which points to a single file /app/mapfiles/test.geojson:
{"type":"Feature","properties":{},"geometry":{"coordinates":[[[122.04067791363536,29.944772490597998],[122.03620089848994,29.94141730774004],[122.03819740524398,29.937852301951125],[122.0446709271447,29.938166866424368],[122.04648593328471,29.940211511256464],[122.04067791363536,29.944772490597998]]],"type":"Polygon"}}
I would like to define the TILEINDEX as one MapServer Layer and have
another MapServer layer reference that tile index. I tried this layer:
LAYER
NAME "vector_via_ogr"
TYPE POLYGON
TILEINDEX tindex_ogr
CONNECTIONTYPE OGR
STATUS OFF
END
but when I run `mapserv -nh
QUERY_STRING='service=WFS&VERSION=1.0.0&REQUEST=getfeature&map=/app/mapfiles/test2.map&typename=vector_via_ogr&OUTPUTFORMAT=geojson'`,
I get the following error:
"msOGRFileOpen(): OGR error. Open failed for OGR connection in layer
`vector_via_ogr'. File not found or unsupported format. Check server
logs."
If I run without CONNECTIONTYPE OGR, I get the following error:
"msTiledSHPOpenFile(): Shapefile error. Tileindex layer must be a
shapefile."
I can get a similar thing working for a TILEINDEX of rasters. However I
cannot get it working on a TILEINDEX of vectors. The example below is the
simplest reproduce case I could create. Ultimately I plan on having a
TILEINDEX point to a layer of defined via CONNECTIONTYPE postgis.
How do I get a vector tileindex working with another Mapserver layer as the
tileindex?
Thanks!

Hi,
I remember that I did tileindexes for vector layers a couple of years ago.
I can?t find my example right now, but I think I was following this example for raster.
The important thing is to have a one layer for the actual tile index, that has status off and one layer that is using the tile index layer. In my case I did it with sqlite if remember correctly. I believe I was following this example for raster, but did it with vector data.

there should be one in the tuitorial

I had started some fixes last week, will continue now (follow along at
https://github.com/MapServer/MapServer-documentation/issues/779 ). If
you ever notice issues with the demo server or any of the many services
relying on it, either email me directly or report the issue in the
'MapServer-documentation' repository. thanks,

Thanks for the message, Lars! This gave me another idea to debug.
When I set DEBUG 5 and request
mapserv -nh
QUERY_STRING='service=WFS&VERSION=1.0.0&REQUEST=getfeature&map=/app/mapfiles/test2.map&typename=vector_via_ogr&OUTPUTFORMAT=geojson'
then the log contains
OGROPen(tindex_ogr)
msOGRFileOpen(): OGR error. Open failed for OGR connection in layer
`vector_via_ogr'. File not found or unsupported format. Check server logs.
Open failed for OGR connection in layer `vector_via_ogr'.
with the layers
LAYER
DEBUG 5
NAME "tindex_ogr"
TYPE POLYGON
CONNECTIONTYPE OGR
CONNECTION "/app/mapfiles/tindex.geojson"
STATUS OFF
END
LAYER
DEBUG 5
NAME "vector_via_ogr"
TYPE POLYGON
TILEINDEX tindex_ogr
CONNECTIONTYPE OGR
STATUS OFF
END
This log line
OGROPen(tindex_ogr)
makes me suspect the following lines of code are setting the OGR dataset
name to "tindex_ogr", whereas I expect it to do something like use the
value from CONNECTION in the layer with name "tindex_ogr".
https://github.com/MapServer/MapServer/blob/71ecf4028b0769027df3a970a36d56feb1d46ab6/mapogr.cpp#L1205-L1238
In other words, I expect the log line to read
OGROPen(/app/mapfiles/tindex.geojson)
and not
OGROPen(tindex_ogr)
This seems to be unique for a vector tile index of vectors. This otherwise
works fine when using a vector tileindex of rasters. So if I make a bogus
raster layer like
LAYER
DEBUG 5
NAME "bogus_raster"
TYPE RASTER
TILEINDEX tindex_ogr
STATUS OFF
PROJECTION
"init=epsg:3857"
END
END
and then issue a bogus request like
curl '
http://localhost:8000/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=true&map=/app/mapfiles/test2.map&layers=bogus_raster&WIDTH=256&HEIGHT=256&CRS=EPSG:3857&STYLES=&BBOX=4163066.308523841,5943743.319455305,4167958.2783340923,5948635.289265556
'
Then the log line includes
msOGRFileOpen(/app/mapfiles/tindex.geojson)...
OGROPen(/app/mapfiles/tindex.geojson)
msConnPoolRegister(tindex_ogr,/app/mapfiles/tindex.geojson,0x556aba222630)
and _not_
msOGRFileOpen(tindex_ogr)...
like I see for a vector tile index of vectors.

Hi,
I made some tests and noticed that the OGR tileindex does not need to be a shapefile but GeoPackage worked as well. Actully what did not work was to make a vector layer from tileindex that was saved into GeoPackage and to use that layer in TILEINDEX. And then I noticed that this behavior is documented in https://www.mapserver.org/input/vector/ogr.html#tileindex-with-ogr:
"OGR layers can utilize tile indexes in a similar fashion to Shapefile based layers. The TILEINDEX keyword should contain the connection string for the tile index file. The tile index file may be any supported OGR format, including shapefiles."
So this is what I used in LAYER and it worked both for WMS and WFS:
CONNECTIONTYPE OGR
TILEINDEX "c:\data\000\mapservertest\tindex.gpkg"
I do not know when and if this behavior has changed. I thought as well that the layer-as-a-tileindex would be the way to follow if tileindex is not in shapefile format.

Interestingly the SVG-related regression tests all pass using a more complex SVG file than what you had shared. Using 8.0, the msautotest/misc/data/Road_Works.svg (https://github.com/MapServer/MapServer/blob/branch-8-0/msautotest/misc/data/Road_Works.svg) file renders fine as a point symbol while your marker_customers.svg does not and matches your sample output. Using the current 7.6 branch, both symbols render as expected as point symbols.
More digging will be necessary. Are any devs aware of specific changes relative to SVG (or vector) symbol support?

Thanks for your message, it is very helpful! I am now struggling how to
use an SQL query of my choosing when the OGR TILEINDEX is in a Postgis
database.
I can get a TILEINDEX working using the OGR format. Ultimately my
TILEINDEX lives in Postgis. I can make a postgis table and populate it
with items like so:
create table testtable (id int, location text, geom
geometry(Polygon,4326));
insert into testtable (id, location, geom) values (1,
'/test_data/test.geojson,0', 'POLYGON((122.01377475333321
29.96355712017804,122.01424752183958 29.915620560607106,122.06927507957919
29.91602043815968,122.0688286928125 29.963957768165944,122.01377475333321
29.96355712017804))'::geometry);
and then reference my Postgis TILEINDEX of vectors in this fashion:
LAYER
DEBUG 5
NAME "vector_via_postgis"
TYPE POLYGON
TILEINDEX "PG:\"host='localhost' user='postgres' dbname='mydatabase'
password='mypwd' tables=testtable(geom)\""
CONNECTIONTYPE OGR
STATUS OFF
END
and now I can query my vector index of tiles:
mapserv -nh
QUERY_STRING='service=WFS&VERSION=1.0.0&REQUEST=getfeature&map=/app/mapfiles/test2.map&typename=vector_via_postgis&OUTPUTFORMAT=geojson'
I can query the database with the OGR driver by passing the `-sql` option:
ogrinfo -ro PG:"host='localhost' user='postgres' dbname='mydatabase'
password='mypwd'" -sql 'SELECT * FROM testtable'
but let's say my query was more complicated than `SELECT * FROM
testtable;`. I could make a Postgres view, but I'm hoping there is some
way to override the default SQL query used.
How do I specify such a query using the OGR PG driver as a Mapserver layer
to be used as a TILEINDEX of OGR vector files?
Perhaps this is more of a GDAL question... or how does Mapserver's use of
OGR TILEINDEX of OGR vector files allow custom SQL? Note that as a
TILEINDEX of Rasters the TILEINDEX can point to a Mapserver Layer, so I
/can/ add custom SQL queries in that case. But I don't know how to do it
as a OGR TILEINDEX pointing to OGR vectors.
Thanks,
Pete

A potential solution would be to create a OGR VRT file that contains
your SQL request, and reference that VRT file in the TILEINDEX
???
??????? PG:"host='localhost' user='postgres'
dbname='mydatabase' password='mypwd'
??????? SELECT * FROM testtable
Actually you may be able to inline the VRT file as the TILEINDEX value
(it is a bit tricky regarding quoting however, but there's an example of
that in https://mapserver.org/input/vector/VirtualSpatialData.html as
the value of CONNECTION, not TILEINDEX, but that shouldn't make a
difference)), since the OGR VRT XML content can be used as a valid OGR
dataset name.

For vector layer, it doesn't look like it is possible to have TILEINDEX
pointing to a MapServer vector layer (contrary to rasters), at least I
can't see any related tests in mapserver regression test suite

Brilliant! This indeed works:
LAYER
NAME "vector_via_vrt"
TYPE POLYGON
TILEINDEX "
PG:host='localhost' user='postgres'
dbname='mydatabase' password='mypwd'
SELECT * FROM testtable
"
CONNECTIONTYPE OGR
STATUS OFF
END
and now requests like
http://localhost:8000/wfs?service=WFS&VERSION=1.0.0&REQUEST=getfeature&map=/app/mapfiles/test.map&typename=vector_via_vrt&OUTPUTFORMAT=geojson
return the vectors pointed by the vector tileindex of vectors. I will
attempt to submit a PR to add this example to the docs when I can.
VRTs: Is there anything they can't do!?
Cheers,
Pete

Hi,
We are using the ?layer-as-a-tileindex? method right now with a bit older Mapserver version and with native POSTGIS connection type. In the orthophoto layer we use
LAYER
GROUP "ortokuva"
NAME "ortokuva_r16"
STATUS ON
TILEINDEX "ortokuva_r16_postgis_tileindex"
TILESRS "crs"
and in the "ortokuva_r16_postgis_tileindex" layer
LAYER
NAME "ortokuva_r16_postgis_tileindex"
STATUS ON
TYPE POLYGON
UNITS METERS
SIZEUNITS PIXELS
CONNECTIONTYPE POSTGIS
CONNECTION "dbname=db user=user password=password"
DATA "the_geom from (SELECT fid, '/beginning/of/path/'||location as location, crs, resolution, the_geom FROM ortokuva_16m) as subquery using unique fid"
I hope that this still works with Mapserver 8. It would be nice if you could make a test and compare OGR vs POSTGIS connection types.

A potential solution would be to create a OGR VRT file that contains your SQL request, and reference that VRT file in the TILEINDEX

Subject: [MapServer-users] Can't pass features attributes to GetFeatureInfo
output
Message-ID:
Hello,
I encountered the problem with GetFeatureInfo, namely:
only one attribute value is passed to GetFeatureInfo output - value of attribute used in mapfile's expression.
My GetFeatureInfo Output:
https://pasteboard.co/lAtZ5HBp1FuT.png
How I defined template:
https://pasteboard.co/uPG1DnJpgE5q.png
and how my mapfile is constructed:
https://pastecode.io/s/txa03nfw
I have checked mentioning another attribute in expression - after that its value was passed into GetFeatureinfo output.
Best,
Marcin
