# Options for updating the trenching indicator {#sec-update}

The trenches map is based on LiDAR which is a dataset we do not assume to become updated
in the near future.
However, trenches can be assumed to not go away by themselves,
so this might not be such an insurmountable issue. 
But updating the indicator needs to rely on some
other information with a higher turnover. We have two candidates.

1. Length of trenches restored (or area affected by this restoration)

1. Change in ecosystem extent

The second option will need to be part of the updating procedure in any case.
The effect of this is explained in @sec-delineation.

Option 1 can be informed by an existing dataset on mire restoration in Norway,
managed by the Norwegian Environment Agency.^[https://services.arcgis.com/2JlC1JM9VNKvqb4F/arcgis/rest/services/Myrrestaurering_Groft_Torvtak_3_visning/FeatureServer] 
There are no restored trenches in our study area, and in general, the area or 
length  restored is minuscule compared to the areas or length that is trenched.
However, this data might still need to go into the updating protocol.
The data can probably be downloaded via an API from AGOL.
