National Spatial Data Infrastructure in Brazil 40 th session of the United Nations Statistical Commission Lunch Time Seminar New York, Feb 25 th, 2009

Introduction Spatial Data Infrastructure – SDI SDI in other countries National Commission of Cartography (CONCAR) Presidential Decree IBGE Actions in Preparing Geospatial Data for NSDI Final remarks Contents

The global demand for geospatial information: in an interconnected world, geospatial information is essential in Many activities Agriculture: Nutrient mapping Phosphorus Distribution Nitrogen Distribution GPS’ed site-specific sampling watershed Manure storage GPS sampling points Source: Rutgers Cooperative Extension Over 60% of all information used by the public sector around the world can be georreferenced Introduction (1/2)

The fast evolving geotechnologies GPS Location based Technology Maps Satellite ImagesAerial Photography DTM CAD/GIS Surveying The trend:as geospatial data become increasingly available, services will become more important to end users This will apply to the geostatistical data as well Introduction (2/2)

Brazilian Statistical Office Example of Georreferenced Statistical data Censuses 2007

Collection seen with Google Earth ® : The yellow line represents the enumeration area boundaries. The yellow points represent points georreferenced by GPS. The red arrow indicates a selected unit for detailed viewing, shown on the right-hand side figure. The corresponding data can be seen by clicking on the point. Visually monitoring data collection

National Statistical Offices What do we need to produce Georreferenced Statistical data?

National Spatial Data Infrastructure - NSDI Policies, laws, rules, standards, agreements, plans, programs, projects, human, technological and financial resources, appropriately integrated, to facilitate the production, access and use of governmental geospatial data, on behalf of the country's development. Technological advances  redefinition of how to make cartography  integrating data and information  optimizing resources  attending the demands !! Georreferenced Statistical data may be seen as Geospatial data up to the consideration of the producer

NSDI Components NSDI POLICY Institutional deals: - Identifying roles and data producers - Elaborate data sharing program (GI)‏ DATA - Definition of thematic data (IG) - Compatibilization - Dissemination TECHNOLOGIC - Protocols and interfaces for communication and search - Server networks - Service (Geo)‏ LEGAL - Legal marks -Institutional mandate -Legal and authoral rights -Rules and legislation STANDARDS - Metadata - Data exchange HUMAN RESOURCES - Levelling knowledge -Technical and managerial Target: distributed GIS over the Internet, composed by data, metadata and services

National Spatial Infrastructure Some Countries experiences

SDI Canada

SDI Colombia

SDI Europe

SDI Spain

Important aspects of NSDI, among others Standards for data, metadata, protocols, etc., in order to guarantee interoperability between NSDI’s nodes Agreements between actors NSDI structure based on Government levels: Federal, State and Municipalities Thematic: environment, transportation, land security, water, foods, education (schools and students), wealth (hospital and health center), etc. OGC

Brazil Actions for building NSDI

National Register of Addresses IBGE is preparing the National Register of Addresses for the 2010 Census, by using the Geospatial Information technology, to: Build a Georreferenced Address File Produce Georreferenced Statistical data

2010 Demographic Census Urban map Linking of block faces to the National Addresses File using Geobase, software developed by IBGE

Quality improvement: urban and rural maps for 2010 Integrated 2010 urban and rural census maps Before

New ways of data dissemination Basic units of dissemination: enumerator areas New ways of dissemination: Street Blocks Geometric areas

New technologies for 2007 and 2010 Censuses Use of PDA equipped with GPS Quality control at the time of survey Real time monitoring of the collecting data in all municipalities Georreferencing of rural establishments (farms, schools, health centers, etc.) Over 70,000 maps of census enumeration areas converted to SIRGAS2000 In 2010 there will be over 280,000 census enumeration areas

IBGE actions for building NSDI IBGE is preparing the geospatial data to contribute to NSDI Update and converting to NCD/MND of continuous digital geospatial data Compose a catalogue of satellite imagery with resolution between 2.5 and 100 m of the entire country  IBGE exclusively distributes ALOS satellite images for non- commercial users in Brazil Note: The census maps that will be prepared to the Census 2010, with intensive use of satellite imagery, will be a rich collection for the construction of SDI Note: The census maps that will be prepared to the Census 2010, with intensive use of satellite imagery, will be a rich collection for the construction of SDI

Source: Digital Census Mapping Process: a conceptual framework and different implementation approaches Post-enumeration Maps make it easier to analyze, display and disseminate; also support survey projects during the decade after the Census Post-Census Enumeration Maps support data collection, monitoring Census Geographic contribution to Census operations Pre-enumeration Maps provide cartographic basis for the delineation of Enumeration Areas Pre-Census Census Cycle Survey Samples Rolling Census

Integrating statistical data into NSDI opens new horizons, based on the possibility of correlating this data with all other data layers, like the ones related to natural resources, environment, education, health, etc. The new web based technologies allow NSO to produce Census Mapping in a full digital way, integrating maps, enumeration areas boundaries, graphic and text files, and addresses register The current availability of low cost high resolution orbital and aerial imagery can help updating the Census Maps The NSOs efforts need to comply with NSDI, which is achievable by following the SDI National Authority Standards – many of which should adhere to the Open Geospatial Consortium standards; by doing this, all geospatial information generated in Census Mapping can be made available through the NSDI Final Remarks
