Demand for geodata

• all spatial planning and decision making needs–a description of geotopography of the earth´s surface–a connection to the earth´s surface

• the description of geotopography consists of–pictorial and objectoriented planimetric information–height information–as geobasis

General demandGeneral demand

Global Responsibility• We may not be affected directly by climate change with life destroying droughts, floods, storms and other disaster

... but we - and life of future generations - will not escape uneffected !!!

• We have a global responsibility.

• Developing our understanding of these issues is extremely important.

• All sectors need to play an equitable part.

• GIS-technologies will have a key role to play in both monitoring impacts on our enviroment and in identifying solutions

realization of „freedom of information“ for public geobasis data of NRW

– public cadastre and topographic data– with first priority for business– and then for business and enduser– that enables to integrate thematic geodata– because of systemindependence and interoperability– to get an extensive governmental informationsystem

Problems

• old concepts for cadastre (ALB/ALK) and topographic (ATKIS) information systems

• no systematic object-related view in ALB/ALK

• strong differences between ALB/ALK and ATKIS

• no consistant data modelling between cadastre and topography

• difficulties in realisation of cartographic aspects

• no “standard” notation of the data models

• no concept to integrate metadata (data quality)

Geodata infrastructure NRW(GDI NRW)

Topic:

linking all puplic and private geodata of NRW• conception• as well as the physical link• based on OGC strategies• for government, business and enduser

Problems• up to now there exists no real market for geodata • because geodata are available extensivly and in different formats• without enough geodata server and meta- information-system solutions

• and without a connection between them

with an enduring economic development with efficient working processes and services from

government to citizens by common activities based on an agreement

from 06. February 1997 in Bonn

- Co-operation North-Carolina - 29

Strategy: support of initiatives in the field of information infrastructure and

spatial information technologyin detail initiatives in

> telecommunication

> spatial information systems

Realisation: definition of common SDI projects:

„harmonization of local, state, federal, continental SDI activities step by step and with respect to the different cultural basis in different areas of the world to get at the end a worldwide SDI solution, the GSDI“

definition of a common geoserver project: „Transfer of the TMS performance to other cultural regions

of the world as next part of a worldwide service network“

Geodata Market

Topic:

Establish a geodata market to

create new services

create new jobs

ensure economic work processes

strengthen user-oriented development and production

- Situation geodata market - 32

Seite 33

Geodata Market

Barriers

no standards

project oriented data capturing

restrictive and intransparent rules for access

missing meta information

redundant capturing and value adding


Seite 34

Geodata Market

Activities

situation is not really known

to realize geodata market investigations have to be done

to capture and analyze the situation

next step is to look for suited activities to overcome the barriers

a study is done as one part of GDI NRW

it can be used as basis for product design, value adding

and delivery

next steps are the SDI projects of GDI NRW


Seite 35

Interoperability

Topic:

for realization of a SDI and geodata market with

reasonable and economic use of geodata an

interoperable geoprocessing is required

Open GIS Consortium serves the inter ...

...rests of all sectors of the industry to realize a

component - based infrastructure for geodata and

develop such a SDI and geodata market.

- Interoperability - 35

Seite 36

Interoperability

Interoperable Geoprocessing

geodata integration

maximized benefit from legacy geodata

geographic feature semantics translation

network-based geoprocessing

better use of databases

componentware

geoprocessing integrated into workflow

new non-expert users and market growth

- Interoperability -

Folder:OpenGIS TM, Consortium, Inc 1996

Seite 37

Interoperability

Open GIS is transparent access to heterogeneous geodata and

geoprocessing resources in a network environment

Open GIS needs a comprehensive open interface specification which

enables developers to write software that provides these capabilities

Open GIS enables to build task-specific geoprocessing functions into

any information system

to bring new capabilities to a wide variety of user environment.

- Interoperability - 37

Seite 38

Transparency on Geodata Market

Topic:

transparency is required to stimulate geodata market

is given by a ´meta information system‘ and a ´meta

meta information system´ that inform about data

availability and address and conditions for access

is given by certificates for homogeneous data description

and conformity with data quality

- Transparency geodata market - 38

Seite 39


Meta information system for geodata

is in preparation by DDGI

based on a consistent and harmonized description

model

will be implemented in 2001 at

Geoforschungszentrum Potsdam

enables geodata owner to present products

- Transparency geodata market - 39

Seite 40


Certification of geodata

is realized by DDGI

based on a consisted and harmonized quality model

is done by order of DDGI (company GZGI)

consist of a conformity check of data description with DDGI quality model

of data with data description

- Co-operation geobase - 40

Co-operation in Geobase

To realize SDI on all levels it is necessary to cooperate between

all geodata relevant disciplines

public and private sector

government, academia and industry

producer, owner, vendor and customer

all nations worldwide

all public levels
