3. Cosa è GeoServer
● GeoSpatial enterprise gateway
– Management dati raster e vettoriali
● Standards compliant
– OGC WCS 1.0 - 1.1.1 (RI)
– OGC WFS 1.0 - 1.1 (RI)
– OGC WMS 1.1.1
● Google support
– KML, GeoSearch, etc..
● Enterprise ready (almost!)

9. Per-layer Security
● Specificare regole su singoli layer
● Configurazione semplificata con liste di
regole
namespace.layer.mode=role1,role2,...
A name, or * to r: read The roles that will
mean “any” w: write be authorized to
access the data
under this rule

10. Per-layer Security
*.*.r=*
RDONLY
*.*.w=NO_ONE lock down
private.*.r=TRUSTED_ROLE
private.*.w=TRUSTED_ROLE Per-layer
override
topp.districts.w=LEGISLATORS
topp. Other
private.* topp.* districts layers
TRUSTED_ROLE r/w r r r
LEGISLATORS (no access) r r/w r

11. Integrazione GDAL
● Started with GSOC 2006-2007
● ImageIO integration via ImageIO-ext
– Estensione SUN ImageIO framework
– JPEG2000,MrSID, ECW, BigTIFF*, ERDAS
Image, HDF4,etc...
– Non (ancora!) facile configurazione
● Problemi di licenza con ECW (?)

20. RESTFul Configuration
● Prototipo iniziale → 2008
● Configurazione programmatica
– Nuovi layer
– Stili
● Esposizione struttura interna
– Ajax-JavaScript friendly
● Expect more in 2009

22. Futuro prossimo: nD Raster
● Raster sono intrinsecamente
multidimensionali
– (x,y,z,t) → [(fieldA1,fieldA2),(fieldB1)]
GFOSS.IT, Pontedera
November 28th, 2008

23. Futuro prossimo: WPS
● WPS 1.0 plugin
● Process back-end in GeoTools
● Integrazione in GeoServer in corso
● Obiettivi
– Raster Processing (WCPS)
– Sextante Integration
– JGrass integration
