This mailing list is about the new project now called LoroDux (formerly
Via-Dux), which will run on java mobile devices, independent of the
The first version will be finished approximately in July 2010, we hope
to publish some beta version for mailing list subscribers in advance.

Salt Lake City looks very good on the map, a close network of streets,
many named and outlined buildings.
Up to now there is no mapper adding information of special interest to
the map there (pedestrian traffic signals with sound etc.)

Did you put OSM conversion and loadstone point share into the same
database? Of course that will cause lots of duplicates.
The OSM page on Salt Lake City sais:
Much of the existing data comes from the TIGER and GNIS imports. Both
datasets suffer from being significantly out-of-alignment from reality.
If you see an object that doesn't match up with where it should be, feel
free to adjust it into line or redraw it in a more accurate location.
The Yahoo imagery and GPS tracks tend to be accurate. TIGER data in the
outer metropolitan areas is better aligned than that in the inner city.
End of quote.
This might be another reason for duplicates.

The loadstone point share exchange has nothing to do with OSM.
To find out how the data quality is, you will have to try with only OSM
conversion in the database.

To help to add point features to the map, you can do this:
Use your standard database to find your way around.
If you have a point of interest, save it with a name that somebody from
the other side of the world is able to tell exactly what it is.
(Not J-F-K-Drive X, but John-F.-Kennedy-Drive crossing with Mainstreet.
Not School for the blind, but Hannah Montana Salt Lake City school for
the blind and deaf, main entrance with 3 steps upstairs)
Use a special character at the beginning of the name, like Exclamation
mark, so you can tell later if it is a private point for yourself only,
or if it is a point you want to have transferred into OSM.
Export your loadstone database to a text file and mail it to me.
I will filter all points with an exclamation mark and add them one by
one to the map, making sure I do not add a duplicate.
I will try to transform the text file automatically so I do not need to
copy the coordinates.
Then remove all exclamation marks from your file before you collect
points again, so I will not have to check the same points a second time.
For the instructions how to add roads see the hyperlink in my last mail.
If anything is unclear, let me know at which step number.
