The Loading and Maintenance of Cadastral Data in the Spatial Data Infrastructure (SDI)

  1. 1. The Loading and Maintenance of Cadastral Data in Manitoba’s Spatial Data Infrastructure (SDI) Bob Bruce & Tony Viveiros FME World Tour 2014 April 11
  2. 2. Presentation Outline • Background to the SDI Project • Description of the Cadastral Datasets • Implementation of Table and Feature Class to house the data • Detailed description of Workbench files and their operation • Next steps 2
  3. 3. What is a SDI? The technologies, policies and people necessary to enable the use of spatially referenced data through all levels of government, stakeholders and the public. SDI Vision: Manitoba’s source for authoritative geospatial data. 3
  4. 4. Manitoba SDI Objectives 1.To build (design and implement) a SDI for the Province of Manitoba that: – stores, manages and disseminates Manitoba’s geospatial data across government and to the public – is scalable to meet anticipated future needs 2.To provide a SDI Governance model that clarifies the tasks and policies required for SDI success. 4

  9. 9. The Cadastral Datasets • Accurately computed cadastral datasets in Winnipeg • Accurately computed cadastral datasets in Manitoba • Manitoba Reference Grid • Northern Quarter Sections 9
  10. 10. Cadastral Datasets in Winnipeg • Maps of areas of Winnipeg on the MLI• Area 6 of the Winnipeg Cadastral Mapping 10
  11. 11. Cadastral Datasets in Manitoba • In the MLI we currently start by accessing data from a map of the province to go to subareas • By clicking on a subarea we go to a map that allows us to select and download data from a dataset 11
  12. 12. Manitoba Reference Grid • Parcel Fabric of Quarter Sections in the surveyed area of Manitoba 12
  13. 13. Northern Quarter Section Grid A computed theoretical quarter section grid of the unsurveyed north 13
  14. 14. Maintaining a Seamless Cadastral Polygon Layer • Each of the cadastral polygon fabrics have been fitted together and are ready to be combined into one polygon fabric • These fabrics are combined into a single GeoDatabase polygon feature class • The individual datasets are tracked with a database table 14
  15. 15. Cadastral Jobs Table A record of which cadastral datasets are currently in the cadastral polygon feature class 15
  16. 16. Workbench Files • One workbench file to ‘decide’ whether an input dataset is a new one or a replacement one and run the processes to populate the feature class and job table • Once workbench file (called by the first one) to actually insert a dataset into the polygon feature class 16

  22. 22. Current Status 22
  23. 23. • Develop processes to import the Northern ‘theoretical’ quarter section grids • Develop a workbench file that uses the Directory and File Pathnames reader to scan folders for datasets and call the workbench files Further Improvements 23
