GeoServer• License: GPL version 2• Environment: Java Virtual Machine• Features

• Data is served as safe and quick images using the WMS protocol

• Full vector data can be sent to a client using the WFS protocol

• Raster data values can be sent to a client using the WCS protocol

• On the fly reprojection• Includes a WMTS Tiling Cache• Analysis and transformation using WPS

Research and DevelopmentWhere GeoServer is heading

62

Time Boxed Release• Predictable releases cycle•Stable: monthly releases

• new features that do not change the API or Stability

•Master• 1-4: open for change proposals• 5-6: release candidate and final release!• s

63

Catalog Service• A very simple Catalog Service

• Publish the GeoServer contents via CSW• Allowing it be easily harvested• (Not a full replacement for GeoNetwork)

• The Service is working• Uses simple Dublin Core backed by text files• API is defined, any one interested in working

on a database implementation

64

Sensor Observation Service• Publish observations & measurements

(often as they are collected)• Service is Currently under construction

• Currently sorting out XML bindings

• Sign up the the developer list to lend a hand!

65

OSGeo Incubation• We are done the checklist• Code / Doc / Data Review to go
