summarize_errors_by definition definition ...
The error summary in the listing file presents error statistics compiled for groups of observations. The groups defined by observation classifications including the default classifications data_file and data_type.
The summarize_errors_by command is followed by one or more summary definitions. Each definition consists of one or more classifications separated by the slash character /.
The default output is created by the command
summarize_errors_by data_type data_file
This creates two separate error summaries. The first shows the statistics accumulated for each data type, and the second the statistics for each data file.
If the command were changed to
summarize_errors_by data_file/data_type
then the listing would show the statistics for each data file, and accumulations for each data type within each data file.
By default the data type summary includes east, north, and up components for vector observation types. This can be suppressed by specifying the classification as "data_type:no_enu".
