All of this is intended to create incentives to protect the long-term value of the area.
Bachelet's visit and Rozzi's determined campaign to recognise the value of the area is starting to bear fruit.
But when you come back here, that dial suddenly gives you the value of the area of this region.
The Unesco committee also says the cultural value of the area has not been clearly defined, despite repeated calls for this.
"The presence of the Ritz name and services, it clearly enhances the value of the area," said John Fox, a senior vice president and hotel industry analyst for PKF Consulting.
In addition, the open woodland contributed to landscape diversity and increased the amenity value of the area for hiking and recreation.
"Anyone who was not northern-European white was considered to be a detraction from the value of the area," said Bruce Mitchell, a senior researcher at the NCRC and one of the study's authors.
In his reasons Tollner said he had considered submissions from supporters, who cited the ecological value of the area, concern for burial sites and its role as a "green belt".
Such interventions are quite costly for cash-strapped policymakers and can only be justified economically if the disappearance of the cypress trees would demonstrably reduce the landscape value of the area.
Icomos, the International Council on Monuments and Sites, which advises Unesco, reported in April 2018 that there would be "irreversible damage" if the scheme went ahead; Unesco's own world heritage committee has said that the project would "impact adversely on the integrity and the outstanding universal value" of the area.
Receiver Operating Curves (ROC) are used as the performance metric to select the optimal model, i.e., the optimal tuning parameters are the ones constructing a model giving the largest value of the area under the ROC curve (AUC) in the resampling CV.
