Geodata to Geoservices Design Issues for GI Infrastructures Josef Strobl Universität Salzburg Austrian Umbrella Organisation for Geographic Information - AGEO
2
Look at the complete picture … GI infrastructures are not ‚just‘ a ► technical or ► organisational or ► business or ► conceptual or ► people … problem, but all of these and then some! ► 10 Building Blocks for SDI‘s! Data etc Data etc
3
Standards ► … of course, that‘s why we there are many of them ► … of course, that‘s why we there are many of them OGC ISO CEN national and industry standards 1
4
Interoperability ► Based on (technical) connectivity ► Implemented as (web) services ► Concepts, Architectures, Standards ► Languages like GML ► ORGANISATIONAL and PEOPLE interop.!! 2
5
Business Model ► Web Services require a distributed, ‚incremental‘ business model based on ► Value Added per service ► Differential pricing schemes result, depending on different value added ► From Value Chain to Value Web! 3
6
Service Level ► Different levels of Quality / Completeness / Scale Currentness Availability Performance / Throughput ► Emergency Services Access 4
7
Workflow / process models ► GII‘s cannot well be defined as collections, but rather as requirements from workflow analysis ► „Same“ item in different workflows can have very different requirements – more than one model (or view) of an aspect of reality! ► Organisationally and socially integrated! 5
8
Metadata ► Describing suitability, fitness-for-use ► Search domain for catalog services ► Profiles are still a research topic! ► Further, ongoing development needed … 6 File Format Data File Format
9
‚Active Catalog‘ Services ► From centralized to distributed cataloging ► Catalog interoperability – independence from entry point into search space ► Search engines with ‚centrifugal‘ sorting 7
10
geo - Integration ► Instead of separate geodata, we want to enable ‚geo-views‘ onto „all“ data ► no ‚geodata‘, but ‚geospatially enabled data sets‘ or ‚…services‘ ► Geo-IT as an integral part of IT! 8
11
Integrated LBS ► LBS components as part of many devices (clients) and services, automatically generating position-focused responses ► geoCommunication – generating ad-hoc communities 9
12
‚real world‘ Geoinformation ► … as opposed to stored representations, data models. ► position encoding in facility infrastructure elements like stations, switches … ► ‚Live GIS‘ – operating directly on critical infrastructure! 10
13
„Thinking Spatially“ ► Awareness ► Education ► Practice
