Creating a new community PWL

This document describes how to create a new community PWL in the InfoEx system.

Background

Community persistent weak layers (Community PWLs) is a new concept in the InfoEx system. Since PWLs often exhibit significant spatial variability and might be buried on a range of days, individual operations might create their Operation PWLs differently. Community PWLs provide a mechanism for linking operation controlled Operation PWLs that relate to the same PWL in nature. This grouping of Operation PWLs allows for more meaningful queries in the InfoEx. For example, the community PWL functionality will allow users to more efficiently get a comprehensive picture on the assessments of a PWL that covers a large area and effectively visualize the associated observed avalanche activity.

NOTE	Please note that the avalanche problem/PWL filtering functionality for the InfoEx report has not been implemented yet!

Step-by-step description

1.	Activate the PWL menu from the main infoEx menu.
2.	Fig. 1: Creating a community PWL Select 'community PWL' beneath 'Pwl' (Fig. 1). The current list of community PWLs is displayed.
3.	Fig. 2: Community PWL settings Select beneath the 'Community PWL' title. This will open a popup window where you can provide the baseline information for your Community PWL.
4.	Provide the following information for your Community PWL (see Fig. 2) Name: Provide a meaningful name for your Community PWL. Date: Provide the date that your Community PWL was buried. Comment: Provide a descriptive comment for your Community PWL, if desired. Operation PWL: You may link your Community PWL to all relevant Operation PWLs (see: Operation PWLs) Colour: Provide a colour that will identify your PWL in hazard assessments.
