Re: [mapserver-users] TileIndex - accuracy and truncation ?

[Rahkonen Jukka (Tike)]

Hi,

I am sure that the accuracy of tileindex vectors does not make the trouble.  
The tileindex is only used for selecting which images will be needed for 
building the requested output image and this is done by selecting polygons 
which intersect with the requested BBOX.  Once the correct image files are 
selected the georeferencing of the images is read from the images themselves, 
in your case from png + WLD.

I suppose that white lines appear when the selected images are subsampled to a 
non-original pixel size for the output one by one. At the image boundary when 
the image pixels cover less than 50% of the output pixel area the corresponding 
output pixel is painted white. Let's say this was at the upper edge of the 
lower tile. Normally when the same pixel is rendered from the lower edge of the 
upper tile there should be more than 50% image data for the pixel and it should 
be rendered with color. Now for some reason also the upper tile yields white 
pixel and the result is "not data for this pixel in lower tile or in upper 
tile".

It is a bit heavy to try to solve the issue only by thinking.  Could you put 
two adjacent tiles with WLD files somewhere so I could have a try with them? 
Tell the EPSG code as well.  Meanwhile, if you have some experience on GDAL or 
if you are willing to learn you can also try to make the mosaic in another way 
than using tileindex. Create a GDAL virtual mosaic file with gdalbuildvrt tool 
and use the resulting .vrt file as datasource for your layer instead of 
tileindex. Read http://www.gdal.org/gdalbuildvrt.html and 
http://www.gdal.org/gdalbuildvrt.html.  As a result GDAL will take care of 
subsampling and it may give different results.

On the other hand, if you could tolerate using GDAL instead of FME you can 
avoid all the trouble by converting your original image into tiled and 
compressed geotiff with overviews.

Hi,

For performance reasons, I've (used FME to) split a large PNG into 450 small 
tiles, serving them with a Mapserver tileindex as a WMS service to a web 
solution.

Howeever, white lines appear between some of the tile rows (not all) at some 
scales (not all).

I've looked deeper into the WLD files for the individual tiles, and found that 
the calculations are accurate to 1/10 of a nanometer. At least if one uses all 
10 decimals.

Tiles are 2254 pixels high, and (as per the WLDs below) 6138899.3169212583 - 
0.0204375000 * 2254 = 6138853.2507962583 (almost equal to 6138853.2507962584)

Which leads me to suspect that some sort of truncation goes on, yielding some 
sort of rounding error.

Do anyone know whether the tileindex calculations truncates any of the values 
in the WLD files ? And if so, by how much ?

Cheers.

A typical map picture with a white line can be seen via this link:

http://hvmgo01.hvenegaard.dk/mswms/mapserv.exe?map=odensekkgd_wms.map&LAYERS=ASSISTENS&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image/png&SRS=epsg:25832&BBOX=586609.80952408,6138781.1015875,586686.025,6138857.3142859&WIDTH=256&HEIGHT=256
Here's the WLD of the two tiles displayed in the picture:

Upper tile WLD:
0.0204375000
0.00
0.00
-0.0204375000
586620.6934394070
6138899.3169212583

Lower tile WLD:
0.0204375000
0.00
0.00
-0.0204375000
586620.6934394070
6138853.2507962584

Ps! As I wrote previously, I'm using FME to create the tiles. So I have little 
control over the actual coordinate and pixel values, and only specify the 
number of tiles I need. So manual truncation is not really a viable option.

yes. you can combine wms_* and wfs_* in metadata-section or use ows_* if
the metadata is the same for wms and wfs.

Yes it is, instead of "wms_" or "wfs_" use "ows_" in your metadata.

Consider also the setting wms/wfs/ows_enable_request "*" to enable/disable
a specific layer for wms or wfs.

Re: [mapserver-users] WFS and WMS

[Rahkonen Jukka (Tike)]

Hi,

I will need to make one first. I am going to use the famous "states.shp" that 
is used as one of the demo layers of Geoserver. I would say that we should have 
something similar for Mapserver, a bunch of mapfiles and some demo datasets 
that could be dropped on the server so that they just work and users could see 
examples about how to make layers from shapefiles, geotiffs, tileindexes, and 
OGR connection and set up WMS, WFS and WCS services, activate GetFeatureInfo, 
use labels and  layer groups with min/maxscaledenom and so on.  That would also 
be a great help when reporting and resolving bugs because all parties could 
have the same data on their computers without pain. An official demo server 
would be a great supporting resource and people could send just links like 
"See, this one is advertised as a Mapserver WFS in http://demo.mapserver.org/ 
but hey, it is WMS at the same!"

Re: [mapserver-users] WFS and WMS

[Rahkonen Jukka (Tike)]

Hi,

A rough example is here. I am sure it is not perfect but at least both WMS and 
WFS layers work with QGIS 2.0. I know there is an odd mixture of ows*, wms* and 
wfs* metadata items.
http://latuviitta.org/downloads/wms-wfs.zip

Zip file contains a Spatialite database for data and a corresponding mapfile. 
They should work as is with MS4W when the installation drive is c:\ and files 
are extracted into c:\ms4w\apps. The path appears only in few places in the 
mapfile but naturally they must be edited if c:\ms4w\apps is not correct.

The WMS layer had a little extra with two labels but I commented them out 
because they require Mapserver 6.2 and such MS4W version does not exist. The 
whole mapfile is so short that I paste it also here below

Re: [mapserver-users] working with date formats in identify templates

[Lime, Steve D (MNIT)]

There's nothing inherent in templates to do this for you but there are options:


1.   Use javascript in the template, something like:


GIS Date:

  var date_jf = '[item name="Date"]';

  // process the date into something prettier
  var date = ...;

 // output the date (zillion ways to do this)
  document.write("" + date +"");




2.   If you're using a db backend you could format things in your SQL.
