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.	Fig. 1: Creating a community PWL Click on the PWL menu in the header of the InfoEx application and select 'Community PWL'(Fig. 1). This will get you to a page that lists of all of the Community PWLs that have been created by the community.
3.	Fig. 2: Community PWL settings Click on the button beneath the 'Community PWL' title to open a pop-up window where you can provide the baseline information for your new Community PWL (Fig. 2). Provide the following baseline information for your new Community PWL: Name A meaningful name for your new Community PWL. Date A rough formation/burial date for your new Community PWL. This date is only used for sorting the list of community PWLs. Comment A descriptive comment about your new Community PWL, if desired. Community PWL You may link your Operation PWL to a Community PWL (see Community PWLs for more information) NOTE Linking your Operation PWL to a Community PWL allows you to retain your local definition and description of the PWL while linking with the same PWL observed by other InfoEx operations Colour A default colour that will identify any assessments and observations associated with this Community PWL in the Infoex report.
3.	Click on the Okay to submit the new Operation PWL to the InfoEx system.
