Background
![Page 3: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/3.jpg)
Evolution of Fire Data
Pull Fire.SHP (poly) from MB Fire Program Used HTTPFetcher to pull down ZIP daily and
overwrite previous days data

Fire – Initial Map
![Page 5: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/5.jpg)
Evolution of Fire Data
Issues with volume and legibility of data Used InsidePointExtractor to pull a point within
polygon to create event theme and filtered out extinguished fires
![Page 6: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/6.jpg)
Fire – Point Representation
![Page 7: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/7.jpg)
Evolution of Fire Data
Move to KML source – added unclassified potential fires and eliminated file handling KML processing
significantly more complicated due to data issues. Had to perform geometry cleaning and XML parsing
![Page 8: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/8.jpg)
Manitoba Hydro Infrastructure
Defined a set of critical electric/gas infrastructure
Transmission Sub-Transmission Stations Distribution Communications Construction Corridor
Used AttributeCreator and LineJoiner to summarize features to how we needed them for the map
![Page 9: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/9.jpg)
Evolution of Fire Data
Added proximity for each fire within 30km of Hydro infrastructure using NeighborFinder Create closest distance attribute to infrastructure
type for Provincial view
![Page 10: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/10.jpg)
Fire – Proximity at MB Level
![Page 11: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/11.jpg)
Evolution of Fire Data
Create line to each of closest critical infrastructure types
![Page 12: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/12.jpg)
Fire – Proximity at Fire Level
![Page 13: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/13.jpg)
Evolution of Fire Data
Added storage of each fire change based on its review date, status or size changes Each time a Fire KML is read, it is compared with
the latest data and new records are created if data has changed
Will be used to track fire progression in 2013 fire season
![Page 14: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/14.jpg)
Near Real Time Weather
KML source read every 15 minutes, wind and temperature of greatest importance for fires
Helps user determine the potential risk based on heat (dryness) and wind strength and direction
Colour indicates temperature, arrow shows direction, while arrow size indicated wind speed Issues with processing included:
Lots of string manipulation for final output Attribute manipulation for final output Duplicates in data needed to be weeded out

Weather Workbench
![Page 16: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/16.jpg)
Weather on Map
![Page 17: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/17.jpg)
Supporting Fire Data
MODIS Hot Spots WMS Service merged into Portal Shows past 24 and 48 hour hot spots
Environment Canada Weather Radar Shows current precipitation and severe weather
Administrative Boundaries and Cadastral Fabric for Land Reference
RCMP and Bulk Fuel locations for Emergencies Several base maps including imagery
![Page 18: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/18.jpg)
Supporting Data
![Page 19: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/19.jpg)
Field Verification
MB Hydro has Satellite Tracking devices for Crew Safety
Can route a Crew (helicopter) to a high risk fire where verification/status required
Web service – refreshed every 5 minutes Automated with Python startup script History of device movement stored Emergency Status can be flagged Automated – bad data handled
![Page 20: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/20.jpg)
Crew Location – FME Key Tasks
Queries Web Service every 5 minutes Write a time stamp to an attribute file when
complete Merges 2 query results into one dataset Use Last written time stamp as start for new web
service query Add new data only Lots of date manipulation Spatial filter takes bad positions and repositions in
case of emergency situation

Crew Location
![Page 23: Fire Proximity Awareness Monitoring with FME](https://reader035.fdocuments.in/reader035/viewer/2022062707/55855d83d8b42a46298b4591/html5/thumbnails/23.jpg)
Crew History – FME Key Tasks
Runs after Points gathered every 5 minutes SpatialFilter only uses data in Manitoba Assembles points into lines based on UTC date/time
sequence using PointConnector LengthCalculator assigns Length attribute StatisticsCalculator assign UTC start and end times

Futures
Full History – so fire progression can be tracked FME Server – better automation and notification Plume Modeling Mobile Handle other Emergencies
Flooding Severe Storms Lightning
