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.

This data set is intended to reflect lands that were sold or transferred by the Crown and are not managed under the mandate of the Ministry of Natural Resources. It may include lands now in title to other: * provincial or federal government agencies * municipal governments * mining patents (surface rights may still be held by the Crown) It is categorized based on: * Geographic Township and a/Area * title holder * forestry rights

An area of land that is of interest to the Crown because of an acquisition. Acquired land is property where the ministry has secured an interest in the land, either directly or through an agent acting on behalf of the ministry. The title is in the name of His Majesty the King in the Right of Ontario or a partner agency. This data class only includes acquired land that is managed by the Ministry of Natural Resources. Other provincial government land that is not managed by MNR is included in the Patent land external data class, where discovered.

These are parcels of land, and land under water — that the Crown has not granted or sold to people or organizations for private use — and are still under ownership of the Crown. These lands are managed by the Ministry of Natural Resources. This data class also includes: * patented properties that are forfeited (forfeitures) back to the Crown * patented parcels that have been depatented * short-term or temporary dispositions For more information about dispositions, see data class the Crown land: MNR non-freehold dispositions.

This Crown land data set includes: * leases * licenses of occupation * land use permits * beach management agreements * easements These are lands with tenanted dispositions by the Crown that have a term. Dispositions may only occur on lands included in either of the following data classes: * Crown land: ministry unpatented land * Crown land: ministry acquisitions
