[Qgis-user] Tif color properties

2011-01-25 Thread Patrick Giraudoux 

Hi,

I am importing (QGIS 1.5.0 - Tethys - Windows XP) a raster (tif format) 
of categories (integers: 1, 2, ... 10). At import, I get an uniform grey 
color. I though that 'pseudocolors' (as it happened in earlier versions 
- long ago) would affect a different color to each category. However, I 
get an uniform 'red' color.


If the tif raster is imported into grass, no problem, the color scheme 
automately given gives different colors to each category.


Has anybody an idea about how to manage to get the same result 
(different colors to each category) in QGIS ?


Cheers,

Patrick

ok - any volunteer who is knowledgeable in Windows and Apache?

I was trying to run it under windows, but have failed making 
apache+fcgi+mapserver working together. My time was too short and I know 
Windows too roughly. But I know many people would be happy if mod_fcgi was 
included into OSGeo4W and preconfigured to run Qgis Server.

Sorry for the mistake, I didn't read carrefully. Without observations,
it will be hard to extract some relevant informations on just
geographical situations (distances matrix?), unless you can work with
others datas (wind speeds and directions, ...) and correlate them with
rainfalls.

Hi Lionel,

Those are good approaches.
I think the problem is that Nikos doesn't have any measurement data yet

Hello,
in first approch you can compute the general mean of your observations
and select only stations with rain mesureaments failing inside a
determinated tolerance around that mean. Another common use would be
to randomly remove some stations and look at the resulting variance
against the general variance (with all stations) and stop when a
tolerance is reached. The best approach would be to play with kriging
your observations and look at the resulting map when some stations are
removed.

Hello,

another idea, unfortunately no solution, would be to ask at the 
r-sig-geo Mailinglist[1] - a list on the statistic-package R, which can 
be used directly in QGIS via the ManageR-Plugin...if you know a little 
bit of statistics and R... but could also be a little bit of overdoing 
if you have never worked with R before...


Maybe an idea...

A manual approach (135 stations is not that much) would be to decide 
on a maximum distance between stations (depends on your analysis 
requirements I guess) and then buffer the station points accordingly. 
You can then manually remove points with redundant/overlapping 
geographic coverage.


But I'm sure there are better solutions :)

Hello List,


I have an interesting problem, and I'd really appreciate if you could
give a couple insightful tips on how you'd solve the following:

I want to order some meteo (rain mm/month for PSDI) data from my
corresponding national agency, but in their infinitive wisdom they
choose to place their weather stations in a pattern that follows
anything but a canonical distribution.

I know this because they sent me a shp file with all their 136
stations
which are available to the general public - for a fee of couse.

Now my problems arise on how I choose  which possible combination
of my
dataset of stations correspond to a canonical distribution of the
mainland - keeping the set of the stations to a minimum as with each
station the cost goes up?
I want to be as much efficient one can be using GIS technology ;)


My initial thinking is to find a subdataset which have their voronoi
polygons created with the same area. But im not so sure if thats the
correct approach

Any tips on how to solve this problem is greatly appreciated!

[Qgis-user] How to Identify the best subdataset of a dataset of points which follow a canonical distribution ?

2011-01-25 Thread nikos 
Hello List,


I have an interesting problem, and I'd really appreciate if you could
give a couple insightful tips on how you'd solve the following: 

I want to order some meteo (rain mm/month for PSDI) data from my
corresponding national agency, but in their infinitive wisdom they
choose to place their weather stations in a pattern that follows
anything but a canonical distribution. 

I know this because they sent me a shp file with all their 136 stations
which are available to the general public - for a fee of couse.

Now my problems arise on how I choose  which possible combination of my
dataset of stations correspond to a canonical distribution of the
mainland - keeping the set of the stations to a minimum as with each
station the cost goes up?
I want to be as much efficient one can be using GIS technology ;)


My initial thinking is to find a subdataset which have their voronoi
polygons created with the same area. But im not so sure if thats the
correct approach

Any tips on how to solve this problem is greatly appreciated!
