Master Plan

1) Create page 5starprocessing.info

2) Establish 5 star scheme for classification of geoprocesses in the web

3) Improve understanding of “geoprocessing” and facilitate their application


3) UNDERSTAND AND FACILITATE GEOPROCESSING


Geoprocessing development directions

Geoprocesses become mainstreamStandardized interfacesSharing new analysis functions“Webified” legacy productsMove from “view” and “download” services to adaptable productsMapping tools extended with geoprocessing APIs


How Should an Open Geoprocess Look Like?

Useful

Easy to use

Easy to integrate

> Applicable in many different applications effectively and efficiently


Relation to Linked Open Data

… is a success… has a ranking scheme

Putting processes online is the natural next step after the data, therefore transfer to geoprocesses!


2) ESTABLISH STAR CLASSIFICATION


“What are the supermarkets on my way home?”

EXAMPLE



EXAMPLE

Process is available on the web under an open license

A web form where I can enter my home and work address and get an HTML list of supermarketsnames and the website allows the use of the

process for any application

★



EXAMPLE

Process (inputs, outputs, ...) is documented on the web and

usable as an API

A RESTful service endpoint is described on an HTML page and the endpoint accepts a route in a proprietary XML format and returns an ordered

text list of the supermarkets’ addresses.

★★



EXAMPLE

Process control interface uses an open standard and the process is

described in machine-readable form

A WSDL endpoint with SensorML description accepting proprietary XML as the route input and returning a shape file with supermarket locations.

★★★



EXAMPLE

Process inputs and outputs use standarized, non-proprietary or

open formats

An OGC WPS process accepting GML/GPX input and returning the locations as GeoJSON.

★★★★



EXAMPLE

All tools and algorithms to execute a geoprocess are

available for re-use under an OSI-approved license

The source code of a geoprocess is published as GPLv3 and can be executed in an Open Source

WPS such as PyWPS.

What do you think is a suitable example process?

What about a 4.5 star geoprocess? Do we need a more finegrained

structure (at a price)?

Is your geoprocess 5 ★?
