When I receive a new point or line-based dataset, often my first action is to use Oasis montaj or Target to look at the channel profiles in a Geosoft database (after importing the data into a Geosoft database, if required). This is a valuable way to check the data quality and get familiar with the data.
Profiles of the coordinate channels (x,y) help to quickly identify location errors from missing values, reversed x and y coordinates, or simple typos. Line data coordinates usually have smooth and consistently increasing (or decreasing) profiles.
Profiles of the data can be used to look for strange values and noise. Selecting any suspicious locations in the profile window will jump to that location in the database table.
I often select the line header cell and use the Page Up and Page Down keys to scroll between adjacent lines in the database for a quick way to review the data.
If this data format is being collected regularly, then saving the database view (Database > Save Working View...) makes the review of data channels more efficient next time.
