Disable Google map recenter function in daily RDAHMM

In response to portal users' requests, we have disabled the "automatic recenter function" of Google map in the daily RDAHMM portlet. The trick turns out to be a "internally used" feature of the GMarker.openInfoWindowHtml() function, which is not included in the official online documents:

marker.openInfoWindowHtml(htmlStr, {suppressMapPan:true});

KML service in daily RDAHMM portlet extended for date ranges

The KML generating function in daily RDAHMM portlet is extended to support date ranges, instead of single dates. The resulted KML will have a "Folder" element which contains a series of "Document" elements corresponding to each date within that date range. Each "Document" is marked with a "TimeSpan" element, so that the whole KML can be played as an animation along the time axis.

Corresponding modifications are applied to the daily RDAHMM result service.

Due to problems with current implementation, the KML function can only support a not-too-long date range, typically shorter than two years. We will try different implementation methods to solve this problem.

New png plotting set-ups in daily RDAHMM service

In daily RDAHMM service, we modified some of the gnuplot scripts so that the png pictures are plotted in the following manner:

(1) All points are first connected with light gray lines;
(2) On top of the gray lines, continuous sections with the same state are plotted with lines of colors corresponding to the state;
(3) On top of the colored lines, all points are plotted with "+"-shaped points of colors corresponding to the states of each point.

De-trend and De-noise options added to daily RDAHMM service

We added de-trend and de-noise functions to the daily RDAHMM service, and these features can be turned on and off by modifying the property files of the service. Since de-noise is done on the output data of de-trend, these options can only be turned on or off together -- that is, the input data is only de-trended and de-noised in a sequence when both options are on; otherwise neither is done. We'll separate them in future work.
