A major new feature in Atlas is the creation of GraphHopper graphs.
Besides opening a ready graph folder to use in routing...
Now you can also select an OSM file (.osm or .pbf or compressed), e.g. from Geofabrik, to build a graph from it.
In that case you need to choose also a target empty folder, where the graph build process will take place.
The graph building could take some time and is memory intensive.
You should probably run the Atlas jar by allocating some memory, via the known Java command line options (i.e. -Xmx).
After the build, the graph is loaded automatically in Atlas.
You can also copy it to Android and use it with Cruiser.
The default graph build options are (car, bike, foot) with contraction hierarchies off.
There is a graph.properties file included to be able to change them easily.
If graph.properties is missing then the default settings are used.

There was a bug in GraphHopper in rare situations.
I have seen it too trying to build a graph for that region and have reported it.
That was just fixed and will be integrated in next version of Atlas (will be soon).
For the time you can alter the graph.properties and choose e.g. only car
That way the graph build for that region will complete successfully.
For generating a graph you can check GraphHopper wiki pages (see here).
It describes how to build a graph via code with contraction hierarchies on / off (and perform routing).

I published new versions of Atlas which
include updated GraphHopper with the aforementioned fix.

(Hint for faster graph creation)
In order to use RAM instead of HD during graph creation, modify the graph.properties file.
Change line:
graph.dataaccess=MMAP
with:
graph.dataaccess=RAM_STORE

Following Emux's tips, I had to run Atlas from a Windows Command prompt window with extra memory allocated:
java -Xmx1024M -jar Atlas.jar
I got a a warning message and an error message which Emux told me could be ignored, but the process worked fairly quickly for producing a graph of Great Britain. Without the extra memory, the process never completed.
java -Xmx1024M -jar Atlas.jar

Those messages are coming from GraphHopper and are harmless for
graphs creation and use.

Atlas (currently Beta) includes a new
feature for GraphHopper graph creation:
Write way names in the preferred language, see graph.properties.
- If no preferred language is specified, only the default language with no tag will be imported.
- If a language is specified, it will be imported if its tag is found, otherwise fall back to default language.
BTW the warning messages were fixed.

Atlas also supports GraphHopper graphs
creation with preferred language via graph.properties
configuration file.

I have simplified the process (for me) by creating a .bat file in the same directory as Atlas with one line:
java -Xmx1024M -jar Atlas-Beta.jar
which runs Atlas-Beta with the extra memory allocated and allows me to construct the graph.
java -Xmx1024M -jar Atlas-Beta.jar
which runs Atlas-Beta with the extra memory allocated and allows me to construct the graph.

Thanks for the hint to the Atlas users!
Maybe I should put 'bat' & 'sh' in next versions to make their life easier. :)

New released versions of Atlas
integrate in their 'exe' the -Xmx1024M option.
I also included 'bat' and 'sh' files with that, for everybody's convenience.
