The Strategic and Operational Use of Digital Spatial Data to Support Survey & Mapping Activities Prof. Richardus Eko Indrajit [email_address]
IT-Based Spatial Data Source
Geographical or geospatial data ( geodata ) and geoinformation , obtained through combinations of geodata, reproduce or describe a territory and its characteristics by means of spatially referenced data such as coordinates, postal addresses, place names or similar criteria.

A Resource of the 21 st Century
Up to 80 percent of all political, economic and private decisions are of spatial nature and related to geodata .
In everyday life, almost everyone uses geoinformation regularly, often without even being aware of it.
Geodata and geoinformation are an economic good of great importance.
Geodata Services
Geodata services or geoservices are electronic services or network applications which facilitate and simplify the use of geodata and allow access to structured geodata.
Geospatial Communities
Due to the broad source and the importance of geodata as well as the enormous range of applications for geoinformation there is a great community of producers, suppliers and users being involved: - central, regional and local government and agencies, - organisations in the private sector, - the scientific community as well as - the general public.
With a wider and more intensive use, greater economic benefit can be achieved from the available geographic information, adding value for each and all.
Spatial Data Infrastructure
In order to use geo-information effectively, it must be up-to-date, compatible and available on a broad basis.
Coordinated policies as well as uniform standards and technologies are essential on global, national and local levels.
A S patial D ata I nfrastructure is a public access system of (political) measures, institutional facilities, technologies, data and people allowing a common exchange and efficient use of geographical information.
The goal of a SDI is to provide users direct access to geodata, geoinformation and geoservices from a variety of suppliers.
Level of SDI
SDIs exist on different levels:
- the Global Spatial Data Infrastructure promotes international cooperation since mid 1990’s
- the National Spatial Data Infrastructure includes public organisations as well as private enterprises on the national level
- the Provincial Spatial Data Infrastructure concerns the geodata of the archipelago
- the Local District Spatial Data Infrastructures are being set up by various parties within the region
National Spatial Data Infrastructure
a broad and effective contact network, which includes all partners
political support on the highest level, defining the legal basis
defining basic geodata and geoservices which are maintained and updated by the administration
defining the required metadata and guaranteeing their actuality
designing and installing the required technical infrastructure
establishing and adopting binding standards for metadata, modelling and data exchange
promoting education, training and research
developing and introducing a common strategy for pricing and distribution
Archipelago Strategy of Geodata
Interdepartmental GI&GIS-Coordination Group
National Spatial Data Infrastructure for the whole country
Basic geoinformation shall be available easily and on easy terms
Coordination with the local authorities and communities
New legal bases if needed
Personal data protection, copyrights, liability, etc. are taken into consideration
Standards for data production and data transfer (metadata, modelling, formats)

quality, accuracy, reliability
integrity, coverage
consistency, compatibility, combinations
easy access, simple use
visualisation
actuality, updating
time series, archives
costs, tariffs, prices
education, training, research
publications, user groups
About ISO/TC211
An international organisation to develop a family of standards in the field of geographic information (e.g. Global SDI Initiatives):
Global Spatial Data Infrastructure (GSDI) to encourage the growth of compatible SDI capable of supporting collaboration on regional and global issues of importance
Digital Earth to help advance the state of technology to create a virtual representation of the planet
Global Mapping to establish a set of spatial framework data coverage for the Earth
About ISO/TC211 (continue)
Why Are GI Standards Necessary ?
For data documentation, collection and exchange of geospatial data
Who Wants GI Standards ?
all businesses that produce, distribute or utilise spatial information benefit from spatial standards
ranges from decision support, data warehousing to modelling and simulation
application areas include automated mapping, geo-engineering, computed-aided drafting and design which support planning and infrastructures such as communication, transportation and utilities
About ISO/TC211 (continue)
aims to establish a structured set of standards for information concerning objects/ phenomena that are directly/ indirectly associated with a location relative to the Earth
the standards may specify methods, tools and services for data management, acquiring, processing, analysing, accessing, presenting and transferring data between different users, systems and locations
shall link to appropriate standards for information technology and data where possible, and provide a framework for the development of sector - specific applications using geographic data
About ISO/TC211 (continue)
increase the understanding and usage of geographic information
increase the availability, access, integration, and sharing of geographic information
promote the efficient, effective, and economic use of digital geographic information and associated hardware and software system
contribute to a unified approach to addressing global ecological and humanitarian problems
