Creates the geographic base data for a study. These include a
study area polygon shapefile, a point grid and a raster each
representing the study area. The study sample dates are defined.
Index variables are initialized (via Static.Import and
TimeSeries.import for the PointID and dates respectivly)
Inputs
study study object
studyshp input study area shapefile
cellsize study cellsize
startdate starting date of the study
enddate ending date of the study
dateinterval max length of sampled intervals
Procedure
assign study parameters
copy and format study area polygon
create study area raster
Import index variables
PID point id number
SDATE sample interval start date
EDATE sample interval end date
Outputs
studyarea.shp study area shapefile
studyraster study area raster
pointgrid.shp study area point grid

Create a randomly sampled subset of study points to export to
easily readable comma separated format (.csv).
Inputs
study study object (after a call to ExtractData() )
outdir subset folder to be created in the study directory
n number of sample points (large n for all points)
Outputs
Variable data tables ( [varname].csv )
For each study output variable a table is produced which is
organized with study sample points in rows and study sample
dates in columns.
Combined case history table ( casedata.csv )
Additionally, a second data table is produced which is a
combination of all the data in the variable data tables. In this
file each row corresponds to a single point at a single date
with each study variable in columns. This table is simply a
combined reorganization of the individual tables
