Simplifing CARMA data
The data returned from the service is simplified (the number of points is reduced). This is configurable with the Application Setting "CARMA line simplification tolerance". The N value can be used to configure the tolerance limit of the CARMA line simplification. This is used to reduce the number of points on the graph. A Lower number indicates more points. The default (in case of N < 0 or missing) is 0.1 mm/yr for CR and 0.1 mm for WT.
