PAST and CURRENT PARADIGMS
Paradigm 1 – Pre-digital, Hardcopy
•
•
•
•
•
Paper maps
Field surveys
Skill sets - cartographers and land surveyors
Dominant institutions - National Mapping
Agencies (NMAs)
Paradigm 2 – Digital Silos
•
Introduction of GIS
•
Building stand alone databases of digital location data; little or no interoperability between
databases in other organizations
•
Focus on single thematic or geographical area
•
Internal own organization focus
•
Digitizing legacy data
•
Skill sets - GIS personnel, data base management
•
Dominant institutions – NMAs, government entities
Paradigm 3 – Spatial Data Infrastructures
• Embracing the web
• Focus on sharing of spatial data from different silos in a web
environment
• ‘Static’ data, much of it describing past situations
• Standards development and implementation play a key role –
software and data standards
• Local, national and global focus
• Skill sets – GIS, standards, data base management, web design,
institutional/governance specialists
• Dominant institutions – government entities, NMAs, private
sector companies role growing

What is a Spatial Data
Infrastructure (SDI)?
“The SDI provides a basis for spatial data
discovery, evaluation, and application for users
and providers within all levels of government, the
commercial sector, the non-profit sector, academia
and by citizens in general.”
--The SDI Cookbook

Spatial Data Infrastructure
SDI requires a framework of spatial data, metadata, users and
tools that are interactively connected in order to use spatial data
in an efficient and flexible way.

Standards
• The first task is to inventory who has what data of what type and
quality
• A standardized form of metadata was published in June 1994 by the
US FGDC. An international standard (ISO 19115/19139) now exists
and is being adopted by most countries

Metadata
Geospatial Data
• Metadata describes data and service resources for order, access, or
local use
• Metadata is used to describe all types of data, emphasis on ‘truth in
labeling’
• Special-use thematic layers are built and described as available
geospatial data
• Common data layers are being defined in the Framework activity
Metadata
Framework GEOdata
Framework Data Standards
• Eleven abstract data content standards are being promulgated
through the ANSI process as American National Standards
• Each theme (layer) is also described as XML/GML Application
Schemas that can be served over the Web (OGC Web Feature
Services)
