Integrated WPS

Automatic publishing of results

Embedding processes into SLD styles

Reuse processes as rendering transformations

16 Febbraio 2012

WPS: news

Deficiencies

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

Create new layers as dynamic WPS processes (computing data on the fly as requested)

New/improved vector stores

Teradata (large databases + analytics/business intelligence)

SQL Server: improved performance, added support for SQL Azure

GeoCouch* (couch db)

GeoGit* (distributed versioning)

Simple Feature Service* client (aka MapFish++ protocol)

New OGR data store*

Aggregating data store*

*: new/experimental

Aggregating data store

N layers, remote or local, sharing the same structure

Aggregating store puts them together dynamically, the client will think there is just one layer

Parallel data fetching

Can be configured to tolerate temporarily unreachable data sources

SQL Parametric Views

SQL View as a GeoServer Layer

No need to actually creating a view in the database

View can be parametric

WMS and WFS allow parameter substitution

….&request=GetMap&viewparams=low:2000000;high:5000000

Default values for parameters

Validation with regular expressions

ImageIO-Ext Support

JAI ImageIO Extension

Plugins:

BigTiff

netCDF-CF, GriB1

MatFile 5

JP2000 (Kakadu)

GDAL 1.8.1

GDAL 1.8.1 integration via ImageIO-ext

JPEG2000,MrSID, ECW

BigTIFF, ERDAS Image, HDF4

Image Server*

Turning GeoServer into an Image Server

Serving pure Imagery

No geo-reference need/available/(would make sense!)

Special Coordinate Reference Systems defined

Interoperability with WMS clients

Respecting EPSG conventions

EPSG:404000

See here

Improved support for data with

bad/missing geo-reference!

Security

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

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, but no integrated solution leveraging it.

External tools available: GeoRepository, GeoShield

GeoRepository

Database level security

Some enterprises want to control security at the database level (instead of at the application level)

The connection pool user gets very limited rights

Pass down the current GeoServer user to the database via SQL script

Security Developments in 2.2.x

Some new security advances are in the works on the unstable series, will be available in 2.2.0:

Pluggable authentication layer (use authentications others than HTTP BASIC ones)

Pluggable user/roles database

Password encryption in configuration files
