Location catalog overview

The location catalog is the backbone of the geospatial InfoEx system. This document give a general overview of the location catalog functionality of the InfoEx application.

Background

All observation entered into the InfoEx system need to be associated with a pre-defined location from your location catalog. For certain observation types, it is possible to also specify a more detailed location in the observation entry screen.

Loocations types

The InfoEx system currently supports the following location types

Location type	Description	Supported geometries
Operation location	Represents main location of operation. Every operation need to have an operation location that acts as the parent for all other locations.	Polygon: Yellow outline with 10% white fill Point: Yellow paddle with square
Forecast area	Larger area that represents a unit for avalanche forecasting purposes. Typical spatial scales range from individuals bowls to large sections of western Canada. Typically used by ski areas, highway and railway forecasters, and public avalanche forecasting agencies.	Polygon: Blue outline with 10% white fill
Operating zone	Larger area that represents a unit for avalanche forecasting purposes. Typically used in mechanized and non-mechanized backcountry operations and commonly represent drainages or groups of drainages.	Polygon: Red outline with 10% white fill
Permanent closure	Permanently closed area of any spatial scales. Typically used in ski areas.	Permanent closure symbology(polygon)
Road	A complete or continuous section of a road. Can be used for both permanent roads (e.g., highways, access roads) and seasonal roads (e.g., cat roads in a catski operation)	Line: Wide white line
Rail	A complete or continuous section of a railway line.	Line: Wide black line
Route	A complete or continuous section of route, typically an uphill ski or climbing route. Primarily used by non-mechanized backcountry operations.	Line: Light green line
Ski run	Approximate location of a ski run	Polygon: Orange outline with transparent orange fill Line: Orange line Point: Red paddle with star
Avalanche path	Location of an avalanche path	Polygon: Fuchsia outline with transparent fuchsia fill Line: Fuchsia line Point: Fuchsia paddle with star
Weather site	Location of a permanent weather or snow profile observation site	Point: Black and white square
Shot placement	Location on an avalanche path regularly used for avalanche control with explosives	Point: Yellow paddle with star
