Re: [mapserver-users] Serving tiled image sets with MapServer?

2014-02-10 Thread Rahkonen Jukka (Tike)

Hi,

First step is to follow the GDAL WMS driver page examples and write a XML 
configuration file for your tile service. Let's call it my_service.xml. You can 
test if the file is correct with GDAL utility programs. If "gdalinfo 
my_service.xml" is listing info about your service and "gdal_translate -of 
GTiff -srcwin 0 0 1000 1000" my_service.xml test_out.tif" writes out a small 
image you are ready to use your service with Mapserver. After that you should 
be ready to use your tile data with Mapserver as
LAYER
  NAME "Layer from tiles"
  DATA "my_service.xml"
  TYPE RASTER
  STATUS ON
...

Hi Jukka,
Thanks for the reply.  I just had a chance to look it over tonight.  I
followed the link to the gdal site, and it does indicate that the GDAL_WMS
driver can access a WorldWind style tile server, which we do have.  Beyond
that, I'm not following your suggestion.  Does the snippet you provided go
in my Mapfile?  I'm not familiar with that.  I am running MapCache, but it
doesn't really look like a grid or source definition.  Where would I use
that snippet?

Re: [mapserver-users] Mapserver can't read mapfile

2014-02-10 Thread Jeff McKenna

Hi sorry long thread and I bet this has already been said, but here were
my thoughts when I read your problems:

- always test your mapfile at the commandline first, using the shp2img
utility (http://mapserver.org/utilities/shp2img.html).  Once your layers
look find there in the generated map image then move to your application

- if using MapServer CGI (mode=map), a blank map often means you are not
specifically telling MapServer to turn on layers; try adding &LAYERS=all

- or setting each of your layer's STATUS values to DEFAULT might work
(but this can cause lots of trouble later, so this is not often recommended)

Stefanos,

It looks like you have a duplicate MAP line in there.

You are also specifying an extent that is from 5 deg west longitude to 0 deg 
longitude and from the equator to 5 deg north latitude.  Does your data fall in 
that part of the world?

David.

I guess the first one is correct and that's why you get the error-msg
with the 2nd one. So, what exactly is the result of the request
http://127.0.0.1/cgi-bin/mapserv?map=/home/mapdata/pelop.map&mode=map ?
it sounds like a white image, not nothing. In this case you should check

Re: [mapserver-users] Σχετ: Σχετ: Mapserver can't read mapfile

2014-02-10 Thread Lars Lingner

Hi Stefanos,

thanks for the mapfile.

Here are some points I would check:

- you habe MAP two times in your file (might be ok, though)
- you don't have a projecten defined
In which projection are your data?

The white color you "see" in your browser come from the IMAGECOLOR. So
MapServer is actually creating a image without objects rendered.

I would enable the debugging to check in the logfile whether MapServer
is getting any data out of your data source.
If this is not the case than you need to check your GetMap request if
the srs and bbox is matching your data source projection.

You also defined the EXTENT with  -5.00 0.00 0.00 5.00. Is this the
correct extent of your source data?

Lars with the help of Jörg :)

Ok, fine.

I would check the webserver error/acces log file.
Also, you can enable debug log in MapServer, see [1].

A blank file (== a white png/jpg I assume) indicates that mapserver is
running fine, e.g. no errors happened while rendering.

It can be a projection issue or expression issue for your classes, so
that MapServer is actually rendering 0 objects.

If you can share your mapfile it would help to give further informations.

Well if I right click and "save image as..." I get a png picture which is

Well I created a new mapfile. Didn't change the already existing one. 

And I just copied and pasted my shapefile to the folder which has full

once again: I have never seen a blank screen when calling mapserver.
I bet there is a withe image try a right-click in your browser-window.

What exactly did you do? Only copying shp-files into the data-folder?
changing the map-file that worked before? creating a new mapfile?

I guess the first one is correct and that's why you get the error-msg
with the 2nd one. So, what exactly is the result of the request

it sounds like a white image, not nothing. In this case you should check

Supposing you had that use-case given your data files, how would you
specify it in a more readable way if you didn't have this syntax?

I'd argue that referencing an existing layer is less confusing. In any
case it is more powerfull, more flexible and more maintainable in our
codebase.

Interesting points nevertheless

To further diagnose this, it would be useful to see the contents of you 
mapfile.  If no errors are being thrown, it is quite possible that there is an 
issue with spatial reference systems, bounding boxes, or class expressions.

Hello,

I can see a difference between

map=/home/mapdata/pelop.map&mode=map

and

map=/home/mapdata/pelop/map&mode=map

Hopefully it is just this typo "." vs "/"

[mapserver-users] Mapserver can't read mapfile

2014-02-10 Thread Stefanos Anastasiou

Hello!!

I'am having my mapfile place in /home/mapdata folder whereas I also keep a 
couple of other mapfiles too. 
I'm trying to load it in the following form on the browser: 
http://127.0.0.1/cgi-bin/mapserv?map=/home/mapdata/pelop.map&mode=map


and all I get is a blank page. No errors no nothing. 

Then I created an html template in order to click it from there by creating a 
simple link (and not a from) in the following hyperlink:  http://127.0.0.1/cgi-bin/mapserv?map=/home/mapdata/pelop/map&mode=map> 
This link 

And I get the following error: msLoadMap(): Unable to access file.  

Last time this happened I was invoking Mapserver through a form but this time 
it's just a simple link. 

Why is it happening ? 

The weird thing is that all the other mapfiles that are seem to be working are 
are having the same permission settings with the current: -rw-r--r-- 

Thanks a lot! ___

[mapserver-users] Dual role of LAYER is confusing

2014-02-10 Thread Rahkonen Jukka (Tike)

Hi,

In most cases in Mapfile LAYER is defining the output of the service. However, 
it looks like the original way to use DATA has not been flexible enough to suit 
new sources of data and as a workaround one layer is used as an input for 
another layer. For example if a shapefile is used as tileindex it is enough to 
write  TILEINDEX "tiger/index.shp" 
However, if one wants to take tileindex from Spatialite it must be done by 
defining a layer first

LAYER  # The tileindex layer
NAME "spatialite_tileindex"
STATUS OFF
TYPE POLYGON
CONNECTIONTYPE OGR
CONNECTION "/orthophotoindex.sqlite"
DATA "select * from orthophotos where year=2013"
   PROJECTION
  "init=epsg:3067" 
END
END # End of tileindex layer
LAYER # The orthophoto layer
NAME "orthophotos_2013 "
STATUS ON
TILEINDEX "spatialite_tileindex"  # Name of the tileindex layer


I guarantee that many if not all new Mapserver users consider this as tricky. 
However, situation can be even more tricky. The new RFC about heatmaps/density 
maps gives an example http://mapserver.org/development/rfc/ms-rfc-108.html.
The source data for the heatmap layer is configured as

LAYER
NAME "heatmap"
TYPE raster
CONNECTIONTYPE kerneldensity
CONNECTION "points"

and here "points" is referring to a layer.  It the "points" layer is using 
ogrtileindex where tileindex is not a shapefile but comes from a database we 
will need three layers for publishing the heatmap:
- ogrtileindex layer
- "points" layer
- heatmap layer

This is doable but confusing. What is also confusing is that I have not yet 
found a way to hide those technical layers from WMS.

Until now after making a web search during a coffee break, it is naturally done 
with a layer level metadata item "ows_enable_request" "!*" as described in 
http://mapserver.org/de/development/rfc/ms-rfc-67.html.  Great. But still I 
feel the dual role of "layer" a bit confusing.  At least in the tileindex case 
I wish I could simply write just one line even if with somehow complicated 
syntax. Perhaps it could be something like

TILEINDEX "SELECT * from orthophotos where year=2013 USING OGR CONNECTION 
/orthophotoindex.sqlite"
