Standards – how and why

• What is a standard and why is it needed

• Solving GIS problems by using standards

• Technical framework and a reference model

• The conceptual model and how to use it

• The application model and how to use it

• How to utilise standards


The Problem

• Who has data?

• Which meaning and quality has the data?

• Is the delivery in accordance with the order?

• How do I get the data into the system?

• What happens when I change system or data provider?

• Shared principles for data descriptions and data transfer

• Data with agreed meaning

• Uniform structure for meta data and data quality

• Automatic data import and data delivery procedures


What is a Standard and Why is it Needed


Users agree on a standard, developed in a joint project, and get it approved by the national standardisation authority

(official standard)

Users agree to utilise a system/concept developed by one user or a group of users. Not approved by the national standardisation authority

(de facto standard)

A producer, or a group of a producers, provide a product that dominates the market

(producer standard)

Who Creates an Application Standard?

• Those who want!

• A number of co-operating players

– Data users and data providers

– Systems and application developers

– Market organisations

– R and D organisations

– Responsible authorities

• The Market is decisive!


Geo Data Provision and Geo Data Management

• How to forward requirements on external geo data producers

• In-house production - methods and mechanisms

• Meta data and Database descriptions

• Quality description and quality assurance

• Updating geo data sets

• Information Proprietor and Information Administrator - two important roles

• A geo data provision concept

• Corporate basic geo data sets for many users


Geographic Information is much more than ”the map”

Everything that is possible to relate geographically

80 – 85 % of all information in most organisations

GIS use is nothing new – the information is the same as today. New tools and new workflows are utilised

Adding the geographic component is just a way to simplify the

use of information from many sources


Some facts

Meta Data


• Information about the contents of data bases

• Digital and analogue data bases – facilitate to find information about

needed/required/desired data

• Structure according to a standard – easy to use, easy to update for the data vendor, multi use of technical solutions

• The first step when searching for data

• Decisive for judgement about the feasibility of a certain data set for a specific purpose

• An aid when searching for any type of information within an organisation – not only in digital format

Quality Assurance and Quality Description


• A basic prerequisite for corporate use

Production quality assurance Quality description

Adequate production methods When Gradual quality check procedures How Relevant SOPs for quality checks By whom Quality check protocols

For which purpose A part of a data deliveryGeometric accuracyInformation traceability

Technical Solutions for a Corporate GIS

• GIS is an IT component

• To utilise an existing IT infrastructure – is that possible

• Additional requirements when implementing GIS

• Tasks and responsibilities

• Levelled solutions

• Use existing solutions – add GIS

• General concept – implementation strategies

• Benefits – how and when

Different Tools for Different GIS Users

Advantages with GIS on Internet/Intranet

• Can be combined with other Web-functions aslinks to documents – images, reports, drawings, Excel-sheets etc

• Is quickly available for many users Web-browser is one component in Windows 98/2000

• Quick access to important information interactive maps, combined with other types of information

• Easy to tailor applications for a certain user category

• COM-technology admits expansion and/or re-use of an application


To Create a GIS Website

• The basic query is: • Who is the user/what is the application supposed to support?

• Subsequent queries:• Internet and/or Intranet-application?

• Is the purpose commercial or ”public service”?

• Which is the requested functionality? – will heavily affect the design of the user interface

• Are the users skilled GIS-workers ?

• What about the entitlement to publish maps on internet?
