ps.map.new was moved to ps.map to be clear.

Neither size nor size_att is proportional to area now. But I know
that usualy area is (should be) used instead of height. Using calculated
area of icon would not be usefull because symbol for one site
may be composed of more icons (repeated sites section in script).
I want add option for function used for size calculation from attribute
(like: linear, sqrt, ln) in future.

You have to calculate new attributes for ps.map and create new site file for now -
should not be problem.
