[mapserver-users] PHP MapScript pixel coordinates to map coordinates

[Shorthouse, David]

Folks,

This question has no doubt been asked many times, but for the life of
me I cannot find a solution. Here's what I'm trying to do:

I have a jQuery-based front-end that uses the wonderful jcrop
extension (http://deepliquid.com/content/Jcrop.html) that helps
coordinate zoom. I'm hoping to use this same front-end to permit
cropping of a resultant map image, which means I need to pass the four
pixel corner coordinates, convert to map coordinates (projection may
be variable), then set the extent such that the resultant map image
will have the same dimensions as that described by the user on the
front-end. So, how can I convert pixel coordinates to map coordinates?
Note that the map projection is not always DD so I cannot merely use
proportions as I have seen in some solutions. Surely this is easier
than I am making it out to be.

Thanks for any advice,

David Shorthouse

[mapserver-users] query by point results in IE vs. Firefox

[Jeanette McBride]

Query by point works fine in IE, but in Firefox it actually returns a point 
about half an inch (screen units) north of the one selected.  (see link below) 
Any ideas?  Thanks!  Jenny

Re: [mapserver-users] RE: Images returning blank

[Rahkonen Jukka]

Hi,

The non-working one is in some other projection than epsg:4326. You will get 
that layer visible by removing projection also from the MAP level and using the 
extents from ogrinfo, but in order to show both layers together you should know 
the correct projection for both datasets.
If projection is given at map level it must suit the extents.  Epsg:4326 and 
EXTENT 2460247.751004 232706.929725 2507483.898985 294550.472704 do not suit.

Based on the errors, it looks like you will need EXTENT to your map file at the 
MAP level.

What do you get when you run ogrinfo against the two shapefiles?  Any 
difference?

Are you adding a URL var for the layer name?  Try setting LAYER STATUS to 
DEFAULT for both layers and see if you get an image back.

[mapserver-users] RE: Images returning blank

[Fawcett, David (MPCA)]

I think that this is pretty obviously your problem.

Before you can transform between spatial reference systems (SRS), you need to 
know what the original SRS is.  To create VE image tiles, it needs to transform 
to 'Web Mercator'.  It can't do that if you don't correctly identify the SRS of 
your layer.

I believe that your lat/lon layer works because it is inheriting the projection 
from the MAP.  For your 'something else' layer, you will need to define the 
correct projection for that layer.

David.

Hi,

I would start by adding EXTENT element at MAP level, see for example

[mapserver-users] Images returning blank

[Kent Morrison]

I have mapserver 5.4.2 installed.

I have two different shape files, one renders properly the other only returns 
blank images

The debug log for the one that does not work returns:

Steve,

I have run MS4W on Windows 2008 Server (32bit) without issues.  If you 
wish to run MapServer in 64bit you would require a custom build.


If you hit any walls you can contact my team for support.

 hello

 I would like to add a symbol at the start and end of a polyline.

 I tried using GEOMTRANSFORM with "start" and "end" in a style block in

 vertex of the polyline, which is not the result wanted :/

 is there any way to do that, beside creating a new point layer ?

Have a look at GROUP[1] and CLASSGROUP[2].

This should should give what you want.

[Steve . Toutant]

Stela
Did you have a look at openlayers example 
 http://openlayers.org/dev/examples/ 
See Feature Info in popup
It will work with a Mapserver WMS.

You got to define an OL control
You also have to make your layer queryable, in your mapfile define a 
tolerance and a template.

Howdy,

Granted it has been awhile since I played with the OL WMS code, but I
think the only way is to use the TOLERANCE and TOLERANCE-UNITS in the
LAYER for mapserver to get the desired 'BBOX' type results.

Hope that helps

Re: [mapserver-users] symbol at start and end of polyline ?

[Oliver Christen]

At first I thought I had some oddity with the data I used for my testing
( see http://dev.camptocamp.com/~ochriste/line_with_style.png with the star 
symbol on every vertex of one line feature)

but after trying with some other set of data, I only have the star symbol on 
start and end of the whole line feature ( and, strangely, also on cross-section 
if the line separate in two at some point ) 
http://dev.camptocamp.com/~ochriste/line_feature_extremities.png
so I thought the problem was solved, but upon zooming on the extrmities of the 
line feature, im again having strange behavior:
http://dev.camptocamp.com/~ochriste/line_feature_extremity_zoomed.png
with multiple star symbols.
the red star in these two image are from the same line feature.

why is there more than 2 stars ?
does the geomtransform 'end' only work for line features consisting of only 2 
points ?

  if you're using postgis, you can use a unique key from your table (i.e. gid)
  if you have a shapefile, you'll have to find an or a combination of 
attributes in the dbf that's unique to identify that particular feature.

  well, if you want only one line segment to have start markers, you must  
tell mapserver which segment that is.

[mapserver-users] handling multiple styles for WMS layers

[Verena Diewald]

Hi list,

I have one question concerning style handling in MapServer. Is it 
possible to define multiple layer styles for my WMS and request the 
single styles in the styles parameter in the GetMap request? And how are 
the single styles defined in the layer section of the mapfile?


Greetings

Verena

Re: [mapserver-users] COM.Geo 2010: Computing for Geospatial Conference & Exhibition (June 2010 Washington DC)

[Jan Hartmann]

Hi Puneet,

Glad to see you are still alive and kicking (hard). Do you still have 
the same good memories as I do of the real "leading conference" of this 
decennium? IMHO, time ***has*** already told ...

Cheers,

Jan

Sounds nice, but...

   

COM.Geo 2010 is a leading conference and exhibition on computing for
geospatial research and application ..
 

How can COM.Geo [sic] be "a leading conference" when the first one is
still six months in the future? [1] And the front page copy on the web
site has such flowery text that I don't know whether to feel flush
with gratefulness or grimace with bitterness at lost opportunity.
Let's see -- "computing driven location based applications" have not
revolutionized anything with the prominent exception of online mapping
for finding directions, cloud computing is still hot air, and the
hottest term of the 90s was not .com but sex, and still is so.

As always, time will tell.

  well, if you want only one line segment to have start markers, you must  tell 
mapserver which segment that is.

hello

I would like to add a symbol at the start and end of a polyline.

I tried using GEOMTRANSFORM with "start" and "end" in a style block in 
the layer but sadely this will add a symbol to all start and end of every 
vertex of the polyline, which is not the result wanted :/

is there any way to do that, beside creating a new point layer ?

thanks in advance
