GeoServer User Interface

Integrated Security

namespace.layer.mode=role1,role2,...

A name, or * to mean “any”

r: read w: write

The roles that will be authorized to access the data under this rule

Spring Security

RBAC on layers and services

Built-in version with simplified rules

GUI: security configuration

Security Developments in 2.1

Security Management at the feature level (record in DBMS) read and write filtering

Hide sensible attributes

Discriminate visible areas on a per-user basis

Rules for services and layers

Server side framework available, open source implementation needed!

RESTConfig

Programmatic configuration of layers via REST calls

Workspaces

DataStores/CoverageStores

Layers and Styles

Exposing internal configuration to remote clients

Ajax-JavaScript friendly

“Core” Module since 2.1

Integrated Security

RESTConfig

GeoServer

Javascript client

Desktop app

GeoBatch

Server side scripts

Styles

Layers Publishing

Automatic Configuration of recurring flows of data

Mass publishing of Layers

WFS

Dissemination and filtering of vector data

WFS 1.0 and 1.1 support with transactions

Formats:

GML 2, 3.1 e 3.2

GeoRSS, GeoJSON

Shapefile (zipped)

OGR (configurable)

Extensions

CQL

WFS 1.0 with on-the-fly reprojection

Complex Feature*

Application/community schemas

Complex Features

Attributes as sub-features

Attributes as list of features

Tree-like structure

Heterogeneous data sources

INSPIRE!

WCS*

Raster data dissemination

Raw raster data useful for analysis, no maps!

Support for TIME and ELEVATION (via ImageMosaic plugin)

WCS 1.0 e 1.1

Output formats

GeoTiff, ArcGrid

GDAL based formats*

Extensions

ELEVATION as band management*

WMS 1.3.0 e SE 1.1

Rendering transformations

Point feature extraction from two band raster data (e.g. Wind(u,v))

Computation of direction and module from SLD

KML/KMZ

TEMPORAL SERIES

KML EXTRUDE KML SUPEROVERLAY

ImageIO-Ext Support

JAI ImageIO Extension

Plugins:

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

JP2000 (Kakadu)

GDAL 1.7.3

GDAL integration via ImageIO-ext

JPEG2000,MrSID, ECW

BigTIFF, ERDAS Image, HDF4

GeoWebCache Integration

GeoServer

GeoWebCache

Persistent raster/KML tile cache

Direct calls to GeoServer rendering engine

Support for layers modified through WFT-T

Support for various tile protocols

GMap, Gearth

OpenLayers, VEarth, Bing

Speed-up factor 10/100

Disk quota support

WMS* Cascading

GetMap and GetFeatureInfo Cascading

Suppport for reprojection on-the-fly

GUI based mass import of remote layers

WPS*

WPS 1.0

Official Extension

Raster and Vector data support

High performance processes development (raster/vector statistics, raster/vector format conversions and more)

Integrated WPS

Automatic publishing of results in WPS

Embedding WPS processes into SLD styles

WPS: demo builder

WPS*

Deficiencies

Asynchronous requests

Missing request limits enforcements (e.g. input/output maximum dimensions)

Wish list:

Scripting (Jython, GeoScript)

Sextante, IDL, JGrass (Grass?) integration

Improved robustness

Jiffle (jai-tools) based raster algebra

Cross-Layer filtering

“querylayer” community module

“Find all sites within 100 meters from roads”

Single CQL filter with WMS:

DWITHIN( the_geom, collectGeometries( queryCollection('roads', 'the_geom', 'INCLUDE') ), 200, meters)
