The module declares and initializes the weather station parameters and does not have a run part. After getting the parameters, the initialization part of the module checks if the input values of location (X,Y) for the weather sites and the HRUs are in decimal degrees or state plane coordinates (or any other consistent distance in feet coordinates). The check is based on the value of kzone, which is the National Oceanographic Survey number (listed in Appendix 3 of documentation report) for the projection for each state (larger states may have 2 numbers). If kzone is less than 1, the module assumes the X,Y-values are in a state plane type of coordinate system. Otherwise, a call to the subroutine plane is made. Plane takes the latitude and longitude (always positive) and converts these values to state plane coordinates. Plane is the U.S. Geological Survey’s General Cartographic Transformation Package (generalized plane coordinate conversion package). For this application, the package has been modified to only complete forward transformation from geographic to plane, and for only the continental United States.
With the general availability of Geographic Information Systems, it is suggested to preprocess the required input X,Y-values from geographic to plane coordinates. The pre-processing will save execution time and allows the input values to be analyzed external to the modeling process.
