[GeoNetwork-users] Map search returns nothing for small extent

We have set up a test geonetwork site v 2.6 using the default settings. As
one of our uses is to keep track of satellite imagery, we have inserted some
quickbird images, using the default raster template. When doing a search,
this appears in the search list, but when searching again with a smaller
extent, it disappears from the search list. I've tested some other
geonetwork sites, with similar result, e.g.:

In http://geonetwork.unocha.org/geonetwork/srv/en/main.home search for
"Predicted areas of suitability for tsetse flies: Uganda" using the extent
(West/East/North/South) 30.5/31/4.3/3 returns one record with the extent
29.5/35.51/4.5/-3. However, decreasing the search extent to 30.5/31/4.3/4
returns 0 records, even though it's clearly within the range of Tsetse map!

I'm sorry that I can't show the example on our on site, as it is on our
internal network. One example record from our own site is shown in the
screenshots below.

Is this an error, or is geonetwork not meant to be dealing with this small
extents?

hey!

any news on this bug? we have same problems. small extents not working even
if the small bbox is fully contained in the data bbox.

Hi

To solve this, a change in the method used for bounding box search should be
done. See http://trac.osgeo.org/geonetwork/ticket/357

Sorry, could not work yet on this. I'll try to have it for next 2.6.1
release.

Jose García

Hey, thanks for the hint. I modified the source code removing the +1 and -1
for bbox and now it works like it should (afaik). But tell me, what do you
do +1 and -1 for bbox?

Hi

I think that's to include also bbox borders in the search, but not much
familiar with that. Other developers I think can give more information about
this.

well if you add 1 to WEST and substract 1 from EAST doesn't that effectively
shrink the bbox? (and if bbox is small enough it can cause illegal values
where East < West)
