arnauld I have seen the same message from you three times now :-)
We don't question that you want to sort how to reproject your coordinates; the
examples provided on the website show how to take information from postgis and
display. Where you are stuck is on your own data and we cannot help you.

hello everybody,
well, these coordinate x=1131270.8550 y=4418856.9693
represent the kind of format which are displayed in my JMapFrame when i
run the application.however, i want rathen that in the JMapFrame
frame, the coordinate will display like that: lon=10.1702667
lat=36.8532032.
I want it like that because, i will draw many
LineString or Point on the map. To do this, i have the file .osm which
supplied me many node which this kind of format lon=10.1702667
lat=36.8532032.(lon reprensent the longitude and lat represent the
latitude).Whereas the format i don't know really this kind of coordinate
x=1131270.8550 y=4418856.9693(i supose that x represent the Northing or
the longitude and y represent the Easting or the longitude ).
If
the solution is to convert these coordinate which are displayed on the
JMapFrame x=1131270.8550
y=4418856.9693 to
lon=10.1702667 lat=36.8532032 which will help me to draw without problem
the differents LineString please tell me and how can i convert them.
May
be i don't take very well the informations in the database postgis, and
it is why i have a lot of problem. If someone can help me with a little
example code to take information into the Postgis database to display
this on the JMapFrame interface in order to compare that with my own
code.
Thank you

I cannot tell when you just list numbers what is going on? Are you saying your
data has the axis the wrong way around? Do you need to covert the data for
display?
I have worked with the osm dataset before without trouble using postgis; so I
suspect you just have things set up a bit wrong. I am not good enough at
postgis to tell you what to type to determine your SRID in your tables; perhaps
you need to visit the postgis
list?

hello every body,
excuse me because i don't know always all to solve my problem.I have tried many
possibilities without success.
I use the database Postgis. I have a file .osm which represent the area of a
geographic map to transfert data to my database Postgis. This have created 5
tables :
"planet_osm_line"
"planet_osm_point"
"planet_osm_polygon"
"planet_osm_roads"
"spatial_ref_sys" and another one.
Though geotools, i have succed to draw my map from the data which are stored
into the database. But i have always this kind of coordinate:
x=1131270.8550 y=4418856.9693; x=1131439.2747 y=4418792.6636 etc which
represent the
point on the map and on the JMapFRame frame i have EPSG: WGS 84 mentionned
.However in the file .osm which resume all the nodes of the map, i have rather
this kind of coordinate:
long=10.1623439 lat=36.8545816; long=10.1702667 lat=36.8532032 etc.
How can i do to have this king of coordinate lon=10.1623439 lat=36.8545816
rather than this x=1131270.8550 y=4418856.9693????
Without this, really my project cannot go head.This embarrasses me
Thank you every body for your help
