Mis-perceptions

[zoidberg]

A once-upon-a-time pro navigator, I was used to juggling map/chart projections according to the job in hand - and understanding the inevitable distortions that each and every projection impose on us and our perceptions. I've been amused by sailing colleagues' blank incomprehension when I search out the survey, updates and projection data on the electronic chart packages bundled with their plotters - especially those with Far Eastern origins - and the childlike blind faith that everything that appears ( or doesn't appear ) on a screen is true, right and reliable.

Here's a Youtube video that might amuse - and/or trigger a 'heads up' moment.....

I thought those were slide shows in Tel Aviv.

And I bet they never got round to the hundred or more datums, each chosen to be a good compromise for a particular country's projection. Until we started converging on WGS84...

Very much a part of my professional career!
