Something’s Burning: Using FME for Data Updates & Decision Support
- 1. Something’s Burning: Using FME for data updates and decision support Barry Otterson Saskatchewan Ministry of Environment October 18th, 2010
- 2. Objectives Data updates > Information Services Corporation (ISC) Sask Cadastral dataset Decision support > Southern Conservation Land Policy > LDIS, R.A.N., Enduring Features, FWDF, Conservation Easement
- 3. Data updates: ISC Sask Cadastral dataset What is this? Saskatchewan’s land parcel data. What does it do? The Sask Cadastral Dataset provides a current, accurate description of land parcels in the province, useful for a variety of applications. Why do we need it? Legal parcel boundaries and ownership records are a critical part of maintaining accurate information on land ownership that aid in decision making.
- 4. Data updates: ISC Sask Cadastral dataset Full product(s) block,boundary,IR,lane,lot,monument,0_hudson_bay_reserve,o_quarter_section,o_riverlot,o_road_allowance,o_road_allowance_int,o_section,park,plan,quarter_section,railway,right_of_way,riverlot,rural_municipality,section,surface,survey_parcel,surveyed_line,township,urban_municipality,provincial_boundary Change records same as above but includes a transaction file.
- 5. Data updates: ISC Sask Cadastral dataset Data Maintained on an Internal ArcSDE at ENV. This location happens to be within 30 metres of the original dataset hosted by ISC! Options for maintaining this data: - Full delete and replace each month - Manual change record transactions - Automated process using FME or other tools
- 8. Data updates: ISC Sask Cadastral dataset A change record shapefile is sent for each theme (i.e. park.shp)
- 10. Deletes are stored only within transaction file
- 11. Adds and modifies are sent with the corresponding geometry.
- 13. Data updates: ISC Sask Cadastral dataset Room to improve -automate creation and posting of version -automate QC/QA? -metadata updates and statistics and ArcSDE compression Ultimate Goal -direct access to ISC’s data! -replication? -WFS? Questions so far?
- 14. Decision Support: Southern Conservation Land Policy -The goal of the SCLP is to attain lands that contribute to the overall conservation of biodiversity in the province while meeting The Saskatchewan Farm Security Act and The Saskatchewan Farm Security Regulations. -Conservation NGO’s obtain lands that contribute to the SCLP. -The Saskatchewan Ministry of Environment is responsible to evaluate those land holdings and long term conservation plans.
- 16. Decision Support: Southern Conservation Land Policy Condensed soup from the policy documents
- 17. Decision Support: Southern Conservation Land Policy What role does FME play? The Ministry processes each conservation organization’s annual land acquisitions to assess the legislative and ecological criteria of the SCLP using ESRI and FME.

- ISC atom layer; every piece surveyed line work ever digitized in the provinceISC FME run to create the above layers in shapefile formatMonthly email indicating that the new data is available on an FTP site for download along with some notes of interest if any major changes have occurred
- 12h 5 or 6 h effort- under 1 hour (12 minutes if you skip the boundary layer)
- - End of month output from isc delivered mid month.
- One of the ways to update features in a database is by using the Feature Based Attribute fme_db_operation. The steps involved are - test the incoming features for a value which will decide between updating, deleting, inserting or ignoringadd the attribute fme_db_operation to the features and assign it a value - either UPDATE/DELETE/INSERT - set the UPDATE KEY COLUMN to some attribute which will match the input features to the database features - in this case it is the attribute “PPID". - change the WRITER MODE on the destination dataset to UPDATE The feature based attribute fme_db_operation is available on most of the database readers and writers
- Report on land purchases to the Ministry are required.
