[GRASS-user] Risultati XVI meeting utenti italiani GRASS GIS e GFOSS
Ciao a tutti, Ci scusiamo per l'eventuale cross-posting! Con questo comunicato vorremmo ringraziare in primo luogo tutti gli intervenuti al XVI meeting degli utenti italiani di GRASS GIS e GFOSS tenutosi il 19 Febbraio scorso a Bologna. La conferenza ha visto la presentazione di 10 interventi nei più svariati campi, tra cui la presentazione della nuova realease di GRASS GIS, tenuta direttamente da Markus Neteler, rilasciata ufficialmente il 22 febbraio 2015 Durante il code sprint ci siamo dedicati alla traduzione della documentazione di GRASS GIS e di OSGeo Live, quest'ultimo rilasciato il 26 febbraio 2015 Circa 20 nuovi utenti hanno partecipato ai workshop introduttivi a QGIS e GRASS GIS. Un sentito ringraziamento ai docenti. Per chi fosse interessato, sul wiki dell'evento troverete il materiale inerente i vari interventi. http://grasswiki.osgeo.org/wiki/XVI_Meeting_degli_Utenti_Italiani_di_GRASS_GFOSS Mentre, a breve, verranno pubblicate sul sito qui sotto alcune foto dell'evento. http://www.scienzeagrarie.unibo.it/it/eventi/convegno-xvi-meeting-degli-utenti-italiani-di-grass-e-gfoss Arrivederci al prossimo anno!

[GRASS-user] Fwd: XVI meeting utenti italiani GRASS e GFOSS: aperte le iscrizioni ai workshop
Mi scuso in anticipo per il cross-posting. Vorremmo annunciarvi che sono aperte le iscrizioni ai workshop GRASS base e QGIS base e che potete sempre inviarci le vostre proposte di presentazioni veloci. X il comitato organizzatore, Elena -- Messaggio inoltrato -- Abbiamo il piacere di comunicarvi che il *19 Febbraio 2015*, dalle ore 9.00 fino alle 18.30 si terrà, presso la Scuola di Agraria e Medicina Veterinaria, Università di Bologna, il *XVI meeting degli utenti italiani di GRASS e GFOSS*. L'evento è organizzato dal gruppo di ricerca del Prof. Fedederico Magnani (Dipartimento di Scienze Agrarie, DipSA), con il patrocinio di GFOSS.it e dello stesso DipSA. Quest'anno la *conferenza *sarà simile ad un Barcamp, con un'introduzione iniziale al mondo GFOSS seguita da una carrellata di brevi presentazioni: chiunque voglia far conoscere e/o cercare aiuto per il proprio progetto sviluppato con o di sviluppo GRASS / GFOSS potrà iscriversi contattando gli organizzatori (*xvimeetinggrassgf...@gmail.com xvimeetinggrassgf...@gmail.com*) e prendere parola alla conferenza. In parallello si svolgeranno: - un *Code Sprint *dedicato a sviluppatori, traduttori, utilizzatori, ecc. Anche in questo caso gli interessati possono presentare le loro proposte contattandoci via e-mail; - due *workshop **di livello base (uno su GRASS GIS e uno su QGIS) per i neo-utenti GFOSS. Per le modalità di iscrizione consultare il wiki dell'evento ai link riportati sotto.* Per maggiori informazioni e aggiornamenti visitate il wiki dell'evento: http://grasswiki.osgeo.org/wiki/IT:XVI_Meeting_degli_Utenti_Italiani_di_GRASS_GFOSS http://grasswiki.osgeo.org/wiki/XVI_Meeting_degli_Utenti_Italiani_di_GRASS_GFOSS Vi aspettiamo numerosi a Bologna!

Hi all, I'm once again in trouble with i.atcorr in GRASS6.5.svn. I notice that my output reflectance images are strange: there are some areas that are really bright and other that are really dark. Both seem to match with my DEM raster. Could there be problems with negative values in DEM?? I'm in a coastal area and there are some real altitude negative values. If you need, this is my r.info of the DEM. http://osgeo-org.1803224.n2.nabble.com/file/n6374760/rinfodemsrtm.txt rinfodemsrtm.txt Hope that someone could help me.. Thank you!

You could set all negative elevation values to zero, Ok, how can I do it? run i.atcorr again and compare the results to the i.atcorr results using the original DEM. If there are any differences that do not make sense, please fill in a bug ticket. Markus M Thank you!

[GRASS-user] Re: i.atcorr output
Hi, I had the same problem. I don't know where your input data come from. Now I know that it works if you use i.landsat.toar to calculate TOA reflectance from DN images and then use these data as input files in i.atcorr: you have also to use the flags -r (because of reflectance input) and -f (because you need floating output). I hope it will work!
