Rview

Rview visualizes radar or lidar data.

Overview

Rview visualizes radar or lidar data.

Prerequesites

The following items are required:

• Radar or lidar data (MDV format)

Parameter file

Rview uses one parameter file that determines the display set up. Unlike most LROSE applications, Rview uses a key/value model instead of TDRP.

Ensure file is up to date

To obtain the default parameter file, use the following command:

/path/to/lrose/install/bin/Rview -print_params > param_file_name

If you already have a parameter file and simply want to check for (and add) updated parameters while retaining current parameters, use the following command:

/path/to/lrose/install/bin/Rview -params orig_param_file_name -print_params > new_param_file_name

Important parameters

Mode and requested time

• mode: determines if the program waits for new files (realtime) or looks for a time specified on the command line (archive)

Geographical extent

• projection: map projection (flat or latlon)
• grid_lat: latitude of the map origin
• grid_lon: longitude of the map origin
• full_min_x, full_min_y, full_max_x, full_max_y: boundaries of viewer, either in km or lat/lon

Colorscale directory

• colorscale_dir: path where color scales are located

Running Rview

To check all command line options for Rview, including debugging options and file paths, type the following command into a terminal.

/path/to/lrose/install/bin/Rview -h

Once your parameter file is complete, use a command similar to the following to run the application:

/path/to/lrose/install/bin/Rview -params param_file_name
