Something’s Burning: Using FME for data updates and decision support Barry Otterson Saskatchewan Ministry of Environment October 18th, 2010
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
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.
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.
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
Data updates: ISC Sask Cadastral dataset Change records in a nutshell: - Change records include all the transactions since the last delivery of the data.
Significantly smaller in size than the full dataset
Add, Delete and Modify
Data updates: ISC Sask Cadastral dataset Transaction.dbf (50,000~ records for August)
Data updates: ISC Sask Cadastral dataset A change record shapefile is sent for each theme (i.e. park.shp)
Data updates: ISC Sask Cadastral dataset FME workbench
Joins transaction.dbf to each shapefile theme and performs the operation (add (insert), modify (update), or delete (delete)) on a version within ArcSDE.
Deletes are stored only within transaction file
Adds and modifies are sent with the corresponding geometry.

Data updates: ISC Sask Cadastral dataset ENV ArcSDE QA/QC Post New version Version fme_db_operation Change records You have been warned here it is FME
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?
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.
Decision Support: Southern Conservation Land Policy Farmland in Saskatchewan should be considered for conservation purchase or conservation easements if the following guidelines are met: 1. Conservation Goal Alignment:
The acquisition is part of a long-term plan of a conservation group filed with and approved by Ministry of Environment.
outlines (among other things) how weeds will be controlled to reduce fire hazards, fence management plans and circumstances under which conservation lands are made available for agricultural uses.
3. Lands Evaluation:
Land acquisition for conservation use should primarily occur where the land has a low capability for cultivation. An explanation of the need for land with higher capability should be provided.
4. Regional Consultation:
The plan has been subjected to adequate regional consultation and has accommodated concerns and issues raised in those consultations.
5. Compliancy Approval/Rejection
Ministry of Environment has reviewed the conservation organizations annual report to determine if the activities are consistent with their long-term plan.
Decision Support: Southern Conservation Land Policy The Full Menu As stated in the Southern Conservation Lands Policy (SCLP) under the heading “Conditions for Purchase of Conservations Lands in Southern Saskatchewan”, subsection (e): “The conservation organization files an annual report with Saskatchewan Environment detailing their land purchases, easements registered, stewardship activities and consultations” And as required by The Saskatchewan Farm Security Regulations, (SFSR, 2006) 37/2006, under section 6(1) subsection (c), point (ii): “The conservation group files annual compliance reports with the Minister of the Environment in an approved form”
Conservation organizations are required to file annual reports to the government
that detail their land holdings for the reporting year.
Decision Support: Southern Conservation Land Policy Condensed soup from the policy documents
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.
Decision Support: Southern Conservation Land Policy Black and white rules in the SCLP
100,000 acres (as of 200606)
-PANP is just under 1 million acres -Moose Mountain is just over 100,000 acres
3% max total land holdings within an RM
-Average size for 3% of an RM’s is 15,500 acres -640 acres in a section / 160 per quarter section -97~ quarters = 3~% of an RM
