Hi
I am developing an application which has dotspatial map control do display S57
dataset.
Here it is displaying fine but I have to write a code where user should be
navigated to particular coordinates when clicking and RCID(it has coordinate
information).

Nikhil,
You should ask the dotspatial community on how to perform the pan/zoom
operations.
To select a feature with a particular RCID, you can set an attribute filter
on that particular layer and request the next feature. Since the RCID value
is unique, you will get the only feature. You have to
Hi all,
I have a raw DSM in ENVI format and i was wondering if there is a way to
select a patch or region out of it and convert it into a polygon mesh. Does
GDAL support this?

Ouch!
Thank you very much, Even. I should have asked sooner, instead of going to
bed at 5 in the morning... :-)
Yes, I have to read into a RGB buffer, but your solution would increase a
lot the loading time for other images that are working well.

Hello,
I have a curious problem with 'gdalinfo' (gdal version 1.9.0 ).
I have an input ENVI file with the following .HDR entry:
data ignore value = -9.9900e+002
gdalinfo for the IMG file provides stats that exclude all values -999.0 as
expected.
I then create a masked output file

Thank you again, Even.
Well, I've taken a look at the documentation you mention, but no answers
there, just an explanation about wgsto84 parameters and a proposal for
extending the geotiff standard in order to embed the famous parameter. I
guess that if you don't say oh man, didn' you know this

Hello,
The one listed as 'failed' actually fails for me as it is sent .
I was experimenting by moving the value near the top of the file.
It continues to fail whether the entry is at the bottom of the file
Or where it appears in the sample that I sent to you.
Could it be a line feeds issue?

First of all let me tell you thanks for your work. Thanks is not enough but
my poor english would put me in troubles if I tried to say something more
complicated. And thank you very much for your answer. Getting help from you

Just to be sure we are talking about the same thing, what do you call fail
exactly ? Is it that gdalinfo doesn't report NoData Value=-999 for the bands
?
Hello,
When I run :
Gdalinfo -stats FILENAME
One file (success) provides statistics calculated by excluding the no data
values.
Ie: min=0.25 max=1234.0 mean=12.0
The other file (failed) provides statistics with -999 calculated into the stats.
Ie: min = -999.0 max=1234.0 mean=-993.0
I have
Hello,
I am seeing that you are correct that the 'no data value' is being read in
each case.
Perhaps my interpretation of the problem appears incorrect.
Look, however at the 'Metadata:' statistics.
Both files have assigned -999 to 'No Data Value' but'STATISTICS_MINIMUM'
for one file

Hello,
At step #6, gdalinfo -stats reports data stats with the -999 values
calculated into the min/max/mean/stdev.

Description = Band 2
Min=-999.000 Max=12.250
Hello,
Good news.
Removing the '.aux.xml ' file and again running gdalinfo -statsindeed
fixes the problem.
I now get the expected statistics values.
Thank you for your help.
