[Geomoose-users] ***PROBABLY FRAUD*** RE: Identifty tool: Unable to interpret fields inraster files...

[Athanasis Nikolaos]

Thank you very much for your help,
 
Reading from the page http://mapserver.gis.umn.edu/docs/howto/raster_data, i realized that in a raster query the only fields I can obtain are:
x, y, value_list, value_n class red, green , blue.
 
Thus, there is no way to calculate other attributes from the raster image.

Please refer to the MapServer help files for this.  In this http://mapserver.gis.umn.edu/docs/howto/raster_data page it explains how to query raster data.  Specifically look at section 8, it has an example of a template for raster queries.  There is also additional info at http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?RasterQuery.

Subject: [Geomoose-users] Identifty tool: Unable to interpret fields inraster files...


Hello !
 
I am trying to use the identify tool in my geomoose application. It  worked ok with shape files, until I tried to add a raster file in the identify.map file. 

My problem is that when i click on the identify tool, then it does not know how to interpret the [ObjectID] field and it shows it as text,  it does not show the number of the ObjectID., it shows exatly : 

"[ObjectID]" as text.....

 
 
Here is the piece of the identify.map file:
LAYER 

NAME 'ddd'

DATA 'county/dtm_lsv1.img'

STATUS ON

TYPE RASTER

TOLERANCE 1

TEMPLATE 'county/identify_DEM.html'

PROJECTION

"init=epsg:2100"

END

END 

 
here is the identify_DEM.html file:
<tr>

<td colspan="2"><b>Test Layer</b></td>

</tr>

<tr>

<td align="right">ObjectID:</td>

<td>[ObjectID]</td>

</tr>

<tr><td colspan="2"><hr></td></tr>

 
here is my map file:
 
MAP

NAME 'please_run'

SIZE 800 650

#PROJECTION

# 'init=epsg:2100'

#END

STATUS ON

EXTENT 654482.650706199 4310740.53966996 729748.549950696 4366667.28424747

#TRANSPARENT TRUE

IMAGETYPE PNG

END

WEB

LOG "/ms4w/apps/GeoMOOSE/maps_statedemo/the_log_file_does_not_work.log"

INCLUDE "/ms4w/apps/GeoMOOSE/maps_statedemo/web_config.map"

END

LEGEND

STATUS ON

END

LAYER

NAME 'DEM'

DATA 'dtm_lsv1.img'

STATUS DEFAULT

TYPE RASTER

#OFFSITE 0 0 0

PROJECTION

'init=epsg:2100'

END #PROJECTION

END #LAYER

END ## end Map

 

You can check what i mean in the following URL:

http://195.251.137.181/geomoose/statedemo.html

Use the identify tool and click where ever you want.... In tghe right panel you see the strange result....

 

Any hints please ???

 

Thank you very much in advance!
