[otb-users] Fine registration

2018-08-03 Thread Gabrielle Hoelzle 
I am having trouble with the fine registration function. I clipped the two 
images to the same size (as close as I could for rasters) but, I still get 
the error that they do not occupy the same physical space. Thoughts on a 
workaround. Is there a better way to prep the images before hand to make 
them more exact in physical space they occupy?

[otb-users] Zonal stats: updating polygons of a vector file by adding fields computed from a raster

2018-08-03 Thread Jordi Inglada 


Hi,

Given an image (raster) and a vector file containing polygons, I need to
compute a series of values for each polygon like the mean of a
particular band of the raster, etc. and then produce a new (or update
the) vector file with new fields. I think these are called zonal
statistics.

It looks like the LSMSVectorization application does that, but it uses a
raster segmentation instead of an input vector file. Given that my
polygons cover only a small fraction of the input raster, I don't think
than rasterizing the vector file to use this application will be
efficient. An besides, I would have to link back the attributes to the
original polygons, which is an additional step.

Is there any other way to do that with existing OTB applications? Maybe
gdal command line tools can do that? I have been looking around and it
seems that this is usually done the way LSMSVectorization does it (burn
the vector to raster, then compute using rasters only).

Do you have any advice on how to proceed if I need to write my own
application for that? I guess I will have to if I want to be able to
compute other features than mean and variance of the raster bands.

By the way, my images and vector data are huge, so streaming and
multi-threading will be needed.

I was thinking about the following approach:

1. Read in a set of polygons until a total surface is reached (so that
   we can associate that with the RAM needed for the total number of raster
   pixels to keep in memory).
2. Project the polygons onto the raster geometry and read in the pixels
3. Parallel computation of the stats (either with an OpenMP loop or a
   simple thread pool [1])
4. Write the geometries and the stats to the output file
5. Release the memory and go back to 1

Any comments on that?

Thanks.

Jordi

 You have to tell PolygonClassStatistics what is the name of the field 
 (the column in the attribute table of your vector data) it should use. For 
 instance, "class".
 Hope that helps.

 Hello everyone,

 I like to run the PolygonClassStaitistics tool in OTB Monteverdi and
 the command line and I get the following error:
 "ERROR: ListViewParameter(01E9C173BDF0): Value id not found in the

 I suppose it has to do with the missing FIELD NAME parameter (should be
 a List). Is there anywhere an example of how this List should be structured
 and saved?
 In the example provided in Orfeo Cookbook (
 https://www.orfeo-toolbox.org/CookBook/Applications/app_Pol
 ygonClassStatistics.html) the file seems to be an sqlite file

 ("variousVectors.sqlite").

 How should a List file describing a polygon shapefile with 2 columns in
 the attribute table look like in order to be read by OTB?

 Thank you,

Hi

This is a known problem in the develop branch right now. We are fixing it:
https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb/merge_requests/188

In the meantime you should probably use the master branch to get the latest 
release, or the specific release you want with branch release-6.6 for example:

git checkout master
