Hi Andrea, Simone, I need some help to get out of this (confusion of mine).
I checked out the sources and tried the maven2 build. The build fails at some point with: /home/moovida/codeapisexes/geotools_svn/trunk/gt/modules/plugin/epsg-postgresql/src/main/java/org/geotools/referencing/factory/epsg/PostgreDataSource.java:[114,7] org.geotools.referencing.factory.epsg.PostgreDataSource is not abstract and does not override abstract method isWrapperFor(java.lang.Class) in java.sql.Wrapper I see different build problems coming through the list, so I assume it is a momentary lapse of reason. However the geotiff jar was build, so I tried to use it and here my doubts and problems: - using the geotiff plugin approach gives me the same error as before (geokey directory), which I expected. - the WorldImageReader uses the geotiff library, right? (it is obvious, but I need some certainties in life :)) Using that, the error is the same as before. I assumed that I would be able to substitute the 2.4 snapshot of the geotiff library and use the thing. That should also be true, since the error I get is not of some dependecy kind. Which library should I substitute to view the paletted geotiff? Thanks Andrea PS: I tried to search for a nightly build in order to try the thing without building all on my own. Is there something like that available? I browsed through the website, but had no luck. * [A.D. 20/01/07 15:30], Simone Giannecchini <[EMAIL PROTECTED]> probably wrote: > Ciao Andrea (both actually!!!), > from the information you send us I can spot two problems: > > 1>A tiff file by itself is not enough for working with georeferenced > data unless it is a geotiff, because you have no CRS (for which you > need a prj file) and no georeferencing (for which you need a wold > file).
