Build risk model limited to asset attribute or spatial extents

The plan is to implement filtering capabilities on the asset data grid and map, and save the filter criteria for further use in other parts of the application. A filter can involve the combination of a spatial filter (e.g., all assets in a defined polygon, or upstream of a pump station) and attributes (e.g., pipes > 12 inch, concrete material and re-dates 1970 installation). Two obvious use cases involve the creation of new risk and a new rehab models. Currently the risk and rehab models are applied to all assets in the tenant. The saved filter will be applied to restrict the risk and/or rehab models to a cohort of assets as defined by the filter. NOTE - this is NOT the same as storing a list of asset-ids resulting from a filter because this is not a dynamically created list. Applying the saved filter criteria will ensure that the list of assets in the cohort are up-to-date in the event that an asset related detail changes - for example a pipe width is changed from 12 inch to 10 inch which would result in it not being filtered according to the previous criteria.
So risk and rehab models can be run on a limited set of assets as defined by the saved filter. This will enable the analysis of specific regions of the sewer and water network (e.g., sewer catchments, DMA zones) and on specific cohorts of assets.
