The document discusses ZOO, an open source WPS (Web Processing Service) platform that allows users to easily create and chain web processing services using FOSS4G libraries or existing code. ZOO is based on a C kernel that can load dynamic libraries and orchestrate web services in multiple programming languages. It aims to standardize how GIS algorithms are made available on the web and automate geoprocessing using spatial semantics and services. The document provides an overview of WPS and ZOO, their current status and implementations, as well as future plans which include supporting additional languages and applications like GRASS GIS and OSM imports.
Making the Argument for Learning Science in Informal Environments - Math in z...K L
Making the Argument for Learning Science in Informal Environments
Level: Intermediate
Demonstrating evidence of learning is becoming critical for museums in securing funding. Yet most evaluation measures do not reflect what goes on in informal environments. The National Academy’s recently summarized research on informal science learning, helping museum professionals make the case for programs. We will review that report (Martin, Arizona Science Center, was a co-author); findings from a national staff development project headed by the Phoenix Zoo (Hebert); and, findings from a visitor survey about conservation learning, conducted at the Arizona-Sonora Desert Museum (Colodner).
The report is important because it broadens the definition of science learning to include motivation, interest, and identity. The Phoenix Zoo project looked at how different institutions supported staff to integrate mathematics into interpretation and how differences in motivation for participating in training influenced staff learning. The Desert Museum conducted a survey on learning about conservation through interactions with docents, looking at changes in visitor knowledge and intentions. Their results allowed them to reflect on the types of interactions they are facilitating.
Discussion will highlight whether the ideas apply to learning in other kinds of museums. Naylor (Arizona Department of Education) represents the stakeholder voice, justifying field trips and other informal programs as valid educational experiences.

Raster data in GeoServer and GeoTools: Achievements, issues and future devel...GeoSolutions
The purpose of this presentation is, on a side, to dissect the developments performed during last year as far as raster data support in GeoTools and GeoServer is concerned, while on the other side to introduce and discuss the future development directions.
Advancements and improvements for the management of raster mosaic and pyramids will be introduced and analyzed, as well as the latest developments for the exploitation of GDAL raster sources.
Extensive details will be provided on the latest updates for the management of multidimensional raster data used in the Remote Sensing and MetOc fields.
The presentation will also introduce and provide updates on the JAITools and ImageIO-Ext projects. JAITools provides a number of new raster data analysis operators, including powerful and fast raster algebra support. ImageIO-Ext bridges the gap across the Java world and native raster data access libraries providing high performance access to GDAL, Kakadu and other libraries.
The presentation will wrap up providing an overview of unresolved issues and challenges that still need to be addressed, suggesting tips and workarounds allowing to leverage the full potential of the systems.
A talk about the OSGeo Live project; covering 43 projects that are available in a live DVD format (for you to run without installing). The project is much improved with OGC documentation and a description of many of the projects. New this year (thanks to some sponsorship) is quickstarts for several of the projects.

THE POWERFUL WPS PLATFORM
CUMTB 2010 Beijing, China
2. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform
WHAT IS WPS ?
What does WPS means ?
Why Pay for Software ?
Not really ....
but it is something similar to that if you think twice after the end of
my talk !!!
3. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform
WHAT IS WPS ?
Web Processing Service is designed to standardize the way that
GIS algorithms are made available on the Internet.
WPS specifies a mean for a client to request the execution of a spatial
calculation from a service.
WPS intends to automate geoprocessing by employing geospatial
semantics in a service-oriented architecture (SOA).
Open Geospatial Consortium interoperability
standards since 2005
WPS Standard was published and accepted
as Standard in 2007
4. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform
Short WPS Overview
Web Processing Service defines three requests :
•
GetCapabilities (as almost all the OWS Standards)
Provides a full overview of all the processes available on the the
requested server.
•
DescribeProcess
•
Provides for a uniq/a set of services Identifiers the specific
description of a/a set of Service.
•
Execute
•
Provides a way to run the Service and ask for the
ResponseDocument or RawdataOutput.
5. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform
WHY USING WPS ?
Web Processing Service allows to deploy and to orchestrate
advanced GIS processes on the server-side.
WPS can connect to any cartographic engine and spatial databases
and thus drive complex spatial data infrastructures (SDI).
WPS is a generic and standardized way to use GIS on the Cloud.
WPS can run FOSS4G and OSGeo tools !
6. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform
WHAT IS ZOO ?
ZOO is a WPS (Web Processing Service) compliant server-side
platform based on OGC's WPS 1.0.0
ZOO is open source software
ZOO is designed to create and chain web processing services easily,
using FOSS4G libs or existing code.
ZOO is based on a C Kernel (ZOO Kernel) able to load dynamic
libraries and to orchestrate Webservices coded in several
programming languages.
7. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform
ZOO PROJECT GOALS
Make FOSS4G libs communicate in a standardized way using WPS
Make GIS-based Web Services deployment and chaining easier and
faster
Create a ready-to-use Webservices suite based on stable libs
Enable advanced Web GIS functionalities such as:
- Conversion, reprojection and processing of data
- Advanced GIS algorithms
- External spatial-based scientific models

10. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform'
HOW DOES ZOO WORK ? (1)
ZOO Kernel handles and chains ZOO Services
A ZOO service is composed of:
A metadata file .zcfg (Title, Metadata, Inputs,Output...)
A Service Provider: « Service Shared Object » (SSO)
( Dynamic library, Python modules, JAVA Class, PHP script ...)
WPS GetCapabilities and DescribeProcess requests requires only
to parse .zcfg file using Flex and Bison
ZOO Kernel is able to load SSO dynamically, to extract specific
functions and to execute them, answering the WPS Execute
requests
12. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform'
HOW DOES ZOO WORK ? (2)
Execute request parsing ( XML / KVP ) to fill internal data structure
- Xlink:href checking , conditional data download to provide input
data value
- Dynamic loading of the Service Provider Shared Objects
- Specific service function call, passing internal data structure by
reference
- ResponseDocument / Raw data output, using the previous data
structure (modified by the service itself)
13. Fenoy, Bozon, Raghavan, 2010. 'ZOO: The powerful WPS platform'
SUPPORTED LANGUAGES
ZOO Kernel supports several programming languages
- C / C++ Native support
- Python Native support (Python interpreter)
- Fortran Optionnal support (F77, F90)
- PHP Optionnal support (PHP embedded)
- Java Optionnal support (Java SDK)
- Javascript Optionnal support (SpiderMonkey)
