Hi Thierry,
This is what I did, I pick up latest Moose, and play a bit. It is nice
indeed.
A few remarks
- loading the tiles is slow, does it comes from me? I am right on the
local tile server in Hsinchu.. I am not sure the right tile server is
used. a.tile.openstreetmap.org
Do you need a dedicated tile server or the generic ones? We had an issue
trying to accelerate tile loading when improving that part during PharoDays.
I'll have a look at Moose to see which version of Roassal you are
dealing with.
- the graphic quality is not optimal, blurred
RTOSM interpolates between tiles zoom levels to gives you more freedom
when zooming; this may comes with a slightly degraded image quality.
Unless it is heavily blurred in which case it is something else. A
screenshot?
- I have a hard time to find live programming (in fact I failed): trying
to get on an inspector was not obvious, then I don't know what I can do
to modify the model and its view
This is more a Moose problem then.
- one RTOSM example fails because of fuel version
There is a problem with the version of Roassal you are using. I remember
correcting that a while ago.
- examples #exampleSeismOnEarthLive #exampleSeismOnEarthLiveZoom fail also.
Yes, the links used to download the data (from the usgs if I remember
correctly) have changed recently; there was a discussion on the mailing
list not long ago (on pharo-dev or moose-dev); I don't know in which
version of Roassal this was corrected.
Thierry
Thanks for the tips

Hi Hilaire,
OSM tiles support was added to Roassal, and demonstrated in two videos
[1][2]. The context of the work was presented at FOSDEM [3].
In the pillarhub document, I demonstrated how to query the raw OSM
data; we made sure that the tile support and georeferenced data could
go on the same level, and be precise to the pixel to the underlying
tile rendering.
I'm sure all this works in Pharo4, just try the RTOSM examples! There
is probably a way to make it interactive with data downloading and a
playground, using the sample code present in the pillarhub document.
[2] is a bit different, it uses a sensor network design tool and
simulateur which requires VisualWorks, Occam and/or a Cuda GPU :). But
it makes for an interesting demo / talk if it is your field, just
contact Onil.

Hi,
In a few weeks I will give a speech in Taiwan at NCHC[1] about Pharo, my
intend is to present release 4. I already did speeches there in the past
about Pharo, but I have a hard time to raise interest to the point
people want to jump in.
But I hope to have an angle this time because NCHC recently offers a
server and the hosting for an openstreetmap tile server (the first in
Asia by the way), and there is high interest here in Taiwan about OSM
related stuff.
I read here, job has been done with Roassal and OSM, but it is not clear
for me how to get in using OSM within Pharo. I am particularly
interested in providing an interactive demo where live programming shows
its value.
I have found these pointers bellow. I am interested by any additional
tips and url, and particularly the compatibility with Pharo4.
