2 ABOUT BRAZIL BRASIL Land area km 2 Sea area km 2 States 27 Municipalities Ppulatin (2010 Demgraphic Census)

3 BRAZILIAN INSTITUTE OF GEOGRAPHY AND STATISTICS Federal Institutin respnsible fr: Official statistics Official reference cartgraphy Gegraphic and envirnmental infrmatin The Institute integrates gegraphy and statistics data and cvers a great diversity f themes IBGE Structure Headquarters: Ri de Janeir 27 state Offices 583 lcal ffices Abut permanent emplyees 192 thusands temprary emplyees during last census peratin

4 IBGE NETWORK Headquater State Units Lcal Agencies Subrdinatin

5 DATA TO THE SOCIETY DIVERSITY OF USERS Gvernmental planning and decisin making (Federal, state and municipal levels). Academic cmmunity. Service cmpanies, market assessment, lcatinal decisins f enterprises etc. Press. Private citizens.

6 DATA TO THE SOCIETY MISCELLANEOUS DEMANDS Easy access t statistical and gegraphical data, in cmpatible frmats with the mst ppular mapping sftware; Availability f statistical and gegraphical metadata; Pssibility t cmpare different scales (several territrial levels); Pssibility t relate infrmatin frm different surces; Pssibility t create custm thematic maps; Access t statistical and gegraphical synthetic analysis (edited maps);

7 NACIONAL SPATIAL DATA INFRASTRUCTURE OF BRAZIL - INDE Established by Presidential Decree f Nvember 27/ 2008 T prmte the prper generatin, strage, access, share, disseminatin and use f gespatial data prduced at federal, state, and municipal level T prmte the use f standards and specificatins certified by the Natinal Cmmissin n Cartgraphy CONCAR T avid duplicatin f effrts and waste f resurces in btaining gespatial data by public administratin bdies

8 NATIONAL SPATIAL DATA INFRASTRUCTURE OF BRAZIL - INDE IBGE is in charge f INDE's rganizatin and functinal aspects INDE Organizatins metadata in IBGE GeNetwrk nly 592 layers published in geserver 317 layers published in the viewer

9 INDE ORGANIZATION STRUCTURE Metadatabase (Genetwrk) runs n free sftware

10 INDE ORGANIZATION STRUCTURE Lcatin-based database (Geserver)

11 INDE ORGANIZATION STRUCTURE Lcatin-based database (Geserver)

14 Example: Slum Areas

15 Example: Slum Areas Images can help the identificatin f Slums areas

16 POSSIBILITY OF RELATE INFORMATION FROM DIFFERENT SOURCES Slum area in Salvadr municipality (IBGE) and subway line under cnstructin (Ministry f Planning)

17 POSSIBILITY OF RELATE INFORMATION FROM DIFFERENT SOURCES High reslutin image f a slum area in Salvadr municipality

18 POSSIBILITY OF RELATE INFORMATION FROM DIFFERENT SOURCES Bime (IBGE) end energy pwer plant under cnstructin (Ministry f Planning)

19 THE IMPORTANCE OF DATA PRODUCTION GATHERED AT INDE Single data and metadata base; Data and metadata standardizatin; Interperability; It avids effrt redundancy; Enables the pssibility f relating the infrmatin frm several institutins.

20 IBGE PRODUCTION AND DISSEMINATION POLICY TO GEOGRAPHIC INFORMATION 1. Grant public and free access t gegraphical and statistical databases; 2. Disclsure f tables and statistics custm retrieval systems; 3. Disclsure f edited maps; 3. Disclsure f the databases f all created maps; 4. Statistical and gegraphical metadata integratin.

21 IBGE PRODUCTION AND DISSEMINATION POLICY TO GEOGRAPHIC INFORMATION Disclsure f tables and statistics retrieval systems IBGE System f Autmatic Retrieval (SIDRA)

22 CREATING CUSTOM TABLES ON SIDRA Disclsure f tables and statistics retrieval systems It is pssible t chse: The statistical variable (ppulatin) The reference date f the data The territrial units t btain the data (States, municipalities, districts, neighbrhd and thers)

23 CREATING CUSTOM MAPS ON SIDRA Disclsure f tables and statistics retrieval systems Chse the territrial units Chse the number f class Chse the interval range Chse the clr IBGE System f Autmatic Retrieval (SIDRA)

24 CREATING CUSTOM MAPS ON SIDRA IBGE System f Autmatic Retrieval (SIDRA) Disclsure f tables and statistics retrieval systems

25 CREATING CUSTOM MAPS ON SIDRA IBGE System f Autmatic Retrieval (SIDRA) Disclsure f tables and statistics retrieval systems

26 IBGE PRODUCTION AND DISSEMINATION POLICY TO GEOGRAPHIC INFORMATION Disclsure f edited maps Disclsure f tables and statistics retrieval systems

27 IBGE PRODUCTS WITH INDE STANDARDS Since 2013 all gegraphical prducts released by IBGE are cnfrm t INDE's standards and they are disseminated as lcatin-based databases. MAJOR EXAMPLES Demgraphic Census Atlas 2010 Territry Management 2014 Cmmerce and Service Natinal Atlas Sustainable Develpment Index Internatinal chart f the Wrld n the millinth scale 250 thusand cntinuus chart f Brazil Vegetatin Gemrphlgy Bime Land use Gelgy Integratin f gegraphy and statistic Reference cartgraphy Envirnmental infrmatin

28 DEMOGRAPHIC CENSUS ATLAS Gegraphic analysis instrument and disseminatin f the 2010 Demgraphic Census The Atlas appraches several dimensins f the ppulatinal dynamics and the demgraphic prfile f Brazilian sciety, with emphasis n reginal and lcal peculiarities.

29 DEMOGRAPHIC CENSUS ATLAS Thematic Structure 1. Brasil and the wrld. 2. Territrial divisin f Brazil. 3. Demgraphic carachteristics. 4. Spatial distributin f ppulatin. 5. Ppulatin flw in the territry. 6. Urbanizatin. 7. Husing cnditins. 8. Scial and ecnmic prfile f the ppulatin. 9. Cultural diversity.

30 DEMOGRAPHIC CENSUS ATLAS DIGITAL ATLAS CARACHTERISTICS: Runs n free sftware Integrated with the paper edited map It grants access t statistical and spatial infrmatin Cnfrm t INDE standards Single database Cnslidated metadata Interperability Enables infrmatin relatins

31 DEMOGRAPHIC CENSUS ATLAS Atlas f Demgraphic Census Integrated with the edited map ad the map fr analyses

32 DEMOGRAPHIC CENSUS ATLAS Atlas f Demgraphic Census It grants acces t statistical and spatial infrmatins

33 DEMOGRAPHIC CENSUS ATLAS Atlas f Demgraphic Census It grants acces t statistical and spatial infrmatins

34 DEMOGRAPHIC CENSUS ATLAS Atlas f Demgraphic Census Cnfrm t INDE standards

35 DATA AND METADATA INTEGRATION ThesummarizedMGBprfileisusedtthethematicinfrmatin,whichis cnfrmed t the ISO nrmatizatin. Cnfrm t INDE standards The file cmprises: Title Reference date Summary Statistical metadata Spatial metadata

36 DATA AND METADATA INTEGRATION Summary field Cnfrm t INDE standards Map cntaining the median age at first marriage f the ttal ppulatin, f the male ppulatin, f the female ppulatin and the difference between the mean age f the male and female married, by municipality. The median age at first marriage was calculated fr persns aged 15 years r lder, based n the technical named Singulate Mean Age at Marriage SMAM, develped by Hajnal (1953)

37 DEMOGRAPHIC CENSUS ATLAS The atlas infrmatins are available in the fllwing frmats: Interperabilty WMS r WFS web service, accrding t OGC standards Maps and database metadata Shapefile KML CSV Table PDF edited map PNG images

38 DEMOGRAPHIC CENSUS ATLAS Atlas f Demgraphic Census Interperabilty

39 FUTURE PERSPECTIVES IN IBGE T cntinue with the plicy f releasing all spatial data as a spatial data service attached t INDE. Creatin f a cmplete website with all IBGE atlases using a web spatial data service accrding t the SDI standards. Integratin f the IBGE Autmatic Retrieval System (SIDRA) t the prductin f spatial data service accrding t the SDI standards. Imprve the integratin between statistical metadata and gegraphical metadata.

40 SOME KEY POINTS The integratin f gegraphy and statistics may starts with simple and inexpensive actins. It can grw step by step. SDIs are the best and inexpensive way t put different kinds f infrmatin tgether and t create new infrmatin, new value. With the SDIs apprach is easier t create new statistics based in different kinds f gegraphic features, included envirnmental features. The SDIs apprach in the integratin f gegraphy and statistics make easier the internatinal data share and integratin. Disclsure the integrated gegraphic-statistics infrmatin thrugh a OGC standards web services is a gd way t guarantee an easy access and the data interperability. Challenge: the creatin f a internatinal standard f a integrated statistical and gegraphical metadata;
