3.3.1 Identifying Source Types and Locations

     The LOCATION keyword is used to identify the source type and the location of each source to be modeled.  The LOCATION card must be the first card entered for each source since it identifies the source type, and dictates which parameters are  needed and/or accepted.  The syntax, type and order of the LOCATION keyword are summarized below:

Syntax:

SO LOCATION  Srcid  Srctyp  Xs  Ys  (Zs)

Type:

Mandatory, Repeatable

Order:

Must be first card for each source input

where the Srcid parameter is the alphanumeric source ID defined by the user (up to eight characters), Srctyp is the source type, which is identified by one of the secondary keywords ‑ POINT, VOLUME, AREA, or OPENPIT - and Xs, Ys, and Zs are the x, y, and z coordinates of the source location in meters.  Note that the source elevation, Zs, is an optional parameter.  If the source elevation is omitted, it will be given a default value of 0.0, but the source elevation is only used if the CO TERRHGTS ELEV option is selected.  While the default units of Zs are meters, the user may also specify source elevations to be in feet by adding the SO ELEVUNIT FEET card immediately following the SO STARTING card.  The x (east‑west) and y (north‑south) coordinates are for the center of the source for POINT and VOLUME sources, and are for the southwest corner of the source for AREA and OPENPIT sources.  The source coordinates may be input as Universal Transverse Mercator (UTM) coordinates, or may be referenced to a user‑defined origin.
