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 |
