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:

<code lang="bash">/path/to/lrose/install/bin/Rview -print_params > param_file_name</code>

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:

<code lang="bash">/path/to/lrose/install/bin/Rview -params orig_param_file_name -print_params > new_param_file_name</code>

==== '''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.

<code lang="bash">/path/to/lrose/install/bin/Rview -h</code>

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

<code lang="bash">/path/to/lrose/install/bin/Rview -params param_file_name</code>
