The Tsunami Notification Zone classifications are used to differentiate the notification areas along the coast of BC. These Zones are used to add BC specific information to tsunami alerts issued from West Coast Alaska Tsunami Warning Center. BC tsunami alerts are disseminated via the Provincial Emergency Notification System (PENS) which encompasses automated phone calls to key stakeholders, faxes, email distribution and updates on the emergencyinfobc.gov.bc.ca website as well as Environment Canada's WeatherOffice, WeatherRadio and MediaWeb services. Each zone has a corresponding level of general risk associated with it, based on a suite of potential tsunami scenarios, which allows emergency managers to estimate the level of risk in each zone.

This dataset provides information submitted by well contractors as prescribed by Regulation 903, and is stored in the Water Well Information System (WWIS). Spatial information for all of the well records reported in Ontario are also provided.

Slope map of Iceland (in Degrees and Percent units). The slope gradient (slope, slope steepness) identifies the steepest downhill slope for a location in a surface: “the inclination of the land surface with respect to the horizontal plane” Basic local land-surface parameters. First partial derivative from surface.

Slope aspect map of Iceland. This tool calculates slope aspect (i.e. slope orientation in degrees clockwise from north) for each grid cell in an input digital elevation model (DEM). “Aspect values indicate the directions the physical slopes face.” The values of each cell in the output raster indicate the compass direction the surface faces at that location. It is measured clockwise in degrees from 0 (due north) to 360 (again due north), coming full circle. Flat areas having no downslope direction are given a value of -1.
