Hi Steve,
Thanks for your answer, it gives me hope.
My issue is complementary with yours :
1) I manage to upload the granule using HTTP PUT. In cURL, it would read:
curl -v -u admin:geoserver -XPUT -H "Content-type: application/zip"
--data-binary @20130101_DV.tif.zip
"http://localhost:8081/geoserver26RC1/rest/workspaces/pigeo/coveragestores/ndvi/file.imagemosaic";
Note that you have to put your files into a zip archive (saw it in the docs)
It does copy the file in my imagemosaic folder.
you would have expected it would update the index, but it doesn't
2) It did try the same request as you outlined, but in cURL. It's not
much different, and indeed documented. But on my instance, it doesn't do
anything at all. I do get a 202, no error, but nothing happens
I'll try tomorrow with other sets of data, maybe it my geotiff files
having something weird inside (but the initial image mosaic generation
is fine, so I would say the files are fine)
If you try the PUT request (upload), I'd be interested to know what it
does on your instance. Will it recompute the index on the fly ?
Next episode tomorrow...

Hi Jean,
I have this working on GeoServer 2.5.1. Here’s what I do to add a
granule to my ImageMosaic+time and with a custom domain attribute:
1.Manually copy the granule, eg Granule_005_20140902_20.tif, to folder
file:///D:/Data/Imagery <file:///D:%5CData%5CImagery> which is where
my ImageMosaic store points to
2.Make an HTTP POST to GeoServer REST API as follows (I’m not using
Curl so you will need to adapt my solution but this should hopefully
give you the key to getting it to work):
a.Method: POST
b.URL:
http://localhost:<geoserver-port>/geoserver/rest/workspaces/<myworkspace>/coveragestores/<my-imagemosaic-store>/external.imagemosaic?recalculate=nativebbox,latlonbbox
<http://localhost:%3cgeoserver-port%3e/geoserver/rest/workspaces/%3cmyworkspace%3e/coveragestores/%3cmy-imagemosaic-store%3e/external.imagemosaic?recalculate=nativebbox,latlonbbox>
c.Body (plain/text format):
file:///D:/Data/imagery/Granule_005_20140902_20.tif
<file:///D:%5CData%5Cimagery%5CGranule_005_20140902_20.tif>
d.After I make this request the ImageMosaic spatial index is updated
in my Postgresql/PostGIS database
This technique is captured in the GeoServer REST API documentation at:
http://docs.geoserver.org/stable/en/user/rest/api/coveragestores.html
“If the coverage store is a simple one (e.g. GeoTiff) it will return a
405, if the coverage store is a structured one (e.g., mosaic) it will
harvest the specified files into it, which in turn will integrate the
files into the store. Harvest meaning is store dependent, for mosaic
the new files will be added as new granules of the mosaic, and
existing files will get their attribute updated, other stores might
have a different behavior.”
NOTE: The granule does not need to be in the folder that the
ImageMosaic points to. In the HTTP request body you can specify a
different location and the granule is just reference from that
location in the spatial index relative to the folder pointed to by the
ImageMosaic.
I would also be interested to hear if anybody has been able to add
granules to an ImageMosaic by uploading them through the REST API, I
was unable to get this to work
.
Hope that helps,
--Steve

Hi Max,
Yes, that's what I meant.
Are you certain about this 'manually edit the index' stuff ?
I don't get it : using REST DELETE command, you can remove a granule,
and it is removed from the index too.
But when you add a granule, it is not inserted in the index ? Isn't it
the point of adding a granule to the mosaic ?
Seems weird, doesn't it ?
Thanks,
Jean

Hi Jean,
if I understand you correctly, you have an existing time enabled
image mosaic and want to add new GeoTIFFs to it, yes?
As far as I am aware the Geoserver ImageMosaic module does not
provide a mechanism to update the granule index when new granules
are added to the ImageMosaic source directory. Instead you need to
add the granules manually to your granule index in your PostGIS
table. You can do this automated through a Script for example.
This script would need to extract the respective parameters from
the new granules (time dimension from filename, geographical
extent from GeoTIFF, path) and write it to a new row in your
granule index table (if the extent is the same for all of your
granules you could also simply copy over the geometry from a
previous granule).
Alternatively you would have to recreate the ImageMosaic every
time you add new granules to it (which would require deleting the
granule index table and deleting the supplementary files that
GeoServer creates on ImageMosaic creation before recreating the
ImageMosaic).
Regards,
Max

*Betreff:* [Geoserver-users] Add data (granule) to an imagemosaic+time
Hi list,
I've got an imagemosaic constituted of several NDVI geotiffs
(using time dimension).
It works very well, but I'm stuck at the "add new data" step.
I've tried several ways : curl
(http://docs.geoserver.org/2.5.x/en/user/rest/examples/curl.html),
gsconfig.
Digging in the REST API, I guess it should have been
curl -v -u admin:geoserver -XPUT -H "Content-type:
application/zip" --data-binary @dv2011.zip
"http://pigeo.fr/geoserver-prod/rest/workspaces/pigeo/coveragestores/NDVI/file.imagemosaic
(the zip file containing my new geotiff file)
Actually, it did add the data in the repository, but didn't update
the index. So it's not really added, just copied in the folder.
I've even tried with several versions of geoserver (2.4.2, 2.5.2,
2.6.RC1) with no changes. So I guess I'm mistaken somewhere in my
process.
My data are geotiffs, all the same. I'm running geoserver under
tomcat7, java 7 oracle.
The mosaic index is stored in a postgis DB.
Any help, please ? Do I need to install some extension ?
Have a nice day,
Jean
