Cruise plot comparisons are useful when the user wants to compare a series of continuous sampling data with model output over some distance in the domain. In the 2DH View the or external to EE, the user should create a polygon to define a "cruise line", which corresponds to the location of data sampling transects that have been undertaken on the waterbody. EE will extract the data from this user defined line and compare it with the measured data. This tool can be accessed by RMC on Cruise Tracks sub-menu as shown in Figure 1.

Figure 1 Cruise Plot Comparisons Form.
Right mouse click on the cells to obtain Station Information form to set the cruise plot data as shown in Figure 2. EE allows the use of two different kinds of cruise plot data. These are defined by station or by track. The user should define a cruise number ID for each data set. This ID will correspond to the USGS defined station IDs. If using native USGS data sets the user should select type 1 for the cruise data type. In this case the format is as shown in Figure 4. If using track data the data form should be as shown for type 2.
The data path should be set for text files that are tab delimited format required for the following parameter as explained above and shown in Figure 2. All the common parameter type codes are based on the list shown in Figure 3.
