This session aims to present the BC250 project of IBGE. This project generated a new digital mapping of the whole Brazilian territory in a 1:250.000 scale with the aid of orbital sensors, DEM and FME. The Geographic Information Systems (GIS) and Remote Sensing are important tools to systematic mapping, these kinds of technologies contributed to increase the production and aquisition of new data faster than used to be. This new digital mapping is the first one provided on the standard called EDGV. This project is part of a new structure of collect, integration and store geospatial data, which in Brazil it is call INDE. The project started in 2008 and on October's 2013, with help of FME that provided workflows capable to create a digital continuous base, the whole country is avaiable on the internet. The 1:250.000 scale is important because it has the power of subsidize the regional planning and helps on studies and projects that’s involve environmental polices.

Mapping Brazil in Scale 1:250.000 - A Reality Presentation Transcript

  • 1. Rafael Balbi Reis Msc. Geography
  • 2. Mission To portray Brazil by provinding the information required to the understanding of its reality and to the exercise of citizenship. Production of Basic information: - Geography; - Statistic (Estatística).
  • 3. Geoscience Territorial Structure Geodesic Cartography Geography Natural Resources
  • 4. Introduction Provide society with a plani-altimetric mapping of Brazil in scale 1:250,000 by continual cartographic vectorial base, compatible with the accuracy requirements of the National Cartographic System and the appropriate standards and regulations of the National Infrastructure Spatial Data (INDE).
  • 5. Hidrography VegetationRelief Transport Energy and Communication Water Supply and Sanitation Education and Culture Economic Structure Localities Public administration Limits Landmarks Health and Social Service EDGV This new standard enables better data sharing, interoperability and a racional use of resources for producers and users of data and information School
  • 6. Project - Methods •  Acquisition and updates of cartographic features with Landsat/TM-ETM Scenes - since 2008; •  Orthorectified with Digital elevation Model of Shuttle Radar Topography Mission and ground control points; •  Information is referenced to SIRGAS 2000 and geodetic coordinates; •  The digital elevation model will be used to extract the altimetric information; •  Other inputs were used in the mapping process like compilation from different scales and information from other institutions.
  • 7. Division by contracts Stages of development
  • 8. • Developing workflows – Partnership INOVAÇÃO; Solution of integration for mapping - FME Data Integration
  • 9. 2008 2009 2010 2011 • Projetc began; •  West from Amazon. • Hiring of mapping company for 4 new parts. Timeline • Preparation of Inspection Manual; • Training of Field Teams; • Collection of information 250. 2012 • Hiring of 3 mapping company for new parts; • Delivery of 4 parts, 2009; • Start of campaing with field teams. • Delivery of 3 parts 2011; • Whole country available on web. 2007 • Integration (FME); • First version BC250-2013. 2013 2014 – Permanent Program Update
  • 10. Using FME Integration •  Transforming of formats. From: Geodatabase – To: Oracle Spatial and PostGIS (Validation of attributes) •  Merge and Join - information and features from the contracts. Permanent Program Update •  Validation of information from continual cartographic vectorial base. (Geometry - Topology) •  Extraction of information from database (ORACLE/POSTGIS) for users inside and outside IBGE.
  • 11. Data Conversion 470 workflows fmw And more...
  • 12. TRANSPORT ECONOMIC STRUCTURE Digital base
  • 13. HIDROGRAPHY LIMITS – SPECIAL AREA Digital base
  • 14. LOCALITIES ENERGY AND COMMUNICATION Digital base
  • 15. http://www.ibge.gov.br/english/
  • 16. Results and Products •  Database (from IBGE) of ground control points - Nearly 2146 points; •  451 Orthorectified scenes used in the project; •  46 Orthorectified mosaics (5R4G3B) in 1:1.000.000 scale; •  Digital Elevation Model mosaics used in the project; •  Elaboration of a database of toponyms for the whole national territory; •  Continual cartographic vectorial base, structured according to the Geospatial Data Vectorial Structure (EDGV); •  Workflows (fmw) for geometric and topology validation.
  • 17. •  The BC250 project arose with the purpose of cataloging, integrating and harmonizing the geospatial data existing in the Brazilian governmental institutions, according to the idea of the INDE; •  Necessity of partners for the maintenance of complementary information; •  Field work for the collection of geographic names, classification of features, etc; •  Developing web services for the access to the INDE; •  Publication of a first version in 2013; a new version will be released every 2 years.
