Hi Kei,

'released' stacks refers to the number of stacks that have been
released into the latest ROS distribution.  So, there are ~150 stacks
that you can install using 'apt-get' right now.

We have some utility scripts that we use to calculate stats:

rosrun rosdoc_rosorg count_packages.py

And, counting released stacks:

$ sudo pip install rospkg
$ python
import rospkg.distro
d = rospkg.distro.load_distro(rospkg.distro.distro_uri('electric'))
len(d.released_stacks.keys())
158

For counting repositories, we have a spreadsheet we use to calculate
the number.  We basically take the repositories listed in the index
and deduct repositories that shouldn't be counted (e.g. from an
individual/institution that has already contributed, renames of older
repositories, etc...).  The current number is 119. One year ago it was
44.

There is a 'meta' section of our repository index that could
potentially be used to store geo coordinates.  It doesn't, currently,
but I'd welcome the contribution.

The index is two-part.  First, a list of rosinstall files:

https://code.ros.org/svn/ros/stacks/rosorg/trunk/rosdoc_rosorg/repos.list

second, the actual rosinstall files:

https://code.ros.org/svn/ros/stacks/rosorg/trunk/rosdoc_rosorg/repos/tum-ros-pkg.rosinstall
