Open Data for the Northern Tornadoes Project 2023 At a Glance NTP - Event Summaries stakeholder surveyPoint All Investigations NTP Investigated Events Query, search and filter through all NTP investigated events in our interactive dashboard. Events are shown in a table and map view for you to explore! Download Data A variety of datasets are maintained for NTP events. These are organized as 'layers' and can be downloaded through one of the links below: Damage Tracks Event Summaries (launch interactive dashboard above) Event Summary Maps These new summary maps provide additional information about investigated events including path length, path width, max wind speed and other information collected by the team. Browse the gallery of summary maps below or explore all event summary maps along with their associated datasets. Investigated events are provided in a snapshot view which are updated by the team as events are reported. If you'd like to search by specific year, province or other category there is also a searchable dashboard with links out to events that have an associated event summary map. NTP Surveys Satellite Surveys Drone Mapping Historic Data Explore NTP Data Pages High-resolution satellite imagery is collected in before and after pairs via Planet Labs, and is used to identify potential damage. Drone mapping takes place in the field, by the NTP Storm Survey Team, to collect high-resolution orthomosaic maps. *Coming Soon* The Michael Newark Digital Tornado Archive is a collection of materials related to tornado and other damaging wind events that will eventually date back to Canada’s first verified tornado in 1792. Drone Ground Aerial Satellite NTP Event Summaries Dashboard surveyPoint Drone Aerial Surveys NTP Event Summaries Dashboard surveyPoint Ground Surveys NTP Event Summaries Dashboard surveyPoint Aircraft Aerial Surveys NTP Event Summaries Dashboard surveyPoint Satellite Surveys Drones are used as part of NTP ground surveys to help identify damage paths, detect damage in areas with limited ground accessibility, and to take photos/video for both analysis and media purposes. Additionally, by flying drones over damaged areas using pre-programmed grids, orthomosaic maps can be generated. Orthomosaic maps consist of a series of individual photos that have been merged to form one corrected composite image, providing a high-resolution overview of the area. Ground photos and associated metadata are collected, mapped, stored and preserved. The NTP Storm Survey Team uses a customized web form to collect observations in the field of reported wind events. The form follows Environment Canada's specifications for classifying wind events based on the Enhanced-Fujita Scale (EF Scale). Aerial Surveys are flown for select sites, the data is collected in high resolution geoTIFF format and uploaded to a mosaic dataset. This dataset along with the associated files are available for researchers to access through the Northern Tornadoes Project ArcGIS for Server Site. KML downloads are available through the Open Data Site. The NTP Storm Survey Team uses high-resolution satellite imagery provided by Planet to review areas of interest for signs of damage following severe weather events. (EF Scale). Contact the Team Report a Tornado Feedback Form Want to contact the NTP Storm Survey Team? They'd be happy to answer any questions you have about the project. Have you seen a Tornado? Be a part of citizen science: report your observations. You can help us map every tornado in Canada! Do you have recommendations or feedback about the Open Data Site? Ideas for improvement? We'd love to hear them. © 1878 - 2023 Western University NTP Storm Survey Team
