STATE_NAME = 'Montana'

MALE > FEMALE

LAND_KM > 300000


ImageIO-Ext Support

Extension of SUN ImageIO framework

New plug-ins:

BigTiff*, netCDF-CF,GriB1,MatFile 5, HDF4

JP2000 based on kakadu

Ongoing work on GDAL 1.7.2

GDAL integration via ImageIO-ext

JPEG2000,MrSID, ECW

BigTIFF, ERDAS Image, HDF4


WFS

Serving raw vector data to the masses!

Support for 1.0 and 1.1 (RI) with Transations

Output Formats

GML 2 and 3

GeoRSS, GeoJSON

Complex Features*

OGR-based extension

Vendor Parameters

CQL

GetCapabilities Namespace filtering

WFS 1.0 reprojection


WCS

Serving raw raster data to the masses!

No maps please I want the real data!

Support for TIME and ELEVATION

Support for 1.0.0 and 1.1.1 (RI)

Output Formats

GeoTiff

GDAL based formats*

Vendor Parameters

ELEVATION as band management*

GetCapabilities Namespace filtering


WFSv


WPS*

WPS 1.0 implementation as extension

Current Implementation is weak:

No Asynchronous Status Hook

No process control

Hard to integrate new processes

Ongoing efforts:

Scripting-based processing

Sextante, JGrass (Grass?) integration

Improved robustness of infrastructure

Raster Processing and Statistics


Raster Pyramids

Preprocessing raster data for performance

Multiple resolutions levels

Scale decide best resolution level

Multiple file (tiles) per resolutions level

File Based Pyramids Support

DBMS-based Pyramids

Postgis

DB2

Oracle (GeoRaster)

MySQL


Pregeneralized Features

Seving big geometries (complex polygons and linestrings)

Multiple generalized version

Fast WMS maps via scale-base selection

Transparent to WFS (read-only)


WMS TIME and ELEVATION

TIME = 20100512T0000000ZELEVATION = 0.0
