OFFSHORE RRERS IN WRTER DEPTHS OF LESS THRN 200 METERS 



THE CONSTRUCTION OF THIS CHART 



This chart is conslrucied on the Lambert 



conformal conic projection, with standard par- 



l latitudes 33° and 45'. 



neridians appear on the chart as straight 



and the parallels as concentric circles; 



and parallels intersect at right angles 



and the angles formed by any two lines on the 



earth's surface are correctly represented- 



Along the two sundard parallels the scale is 

 exactly 1.3.000.000; between ihcm, the scale is 

 slightly smaller, and beyond ihem it is shghtly 

 .urposcs i( will be sufficiently 

 accurate to use the scale at latitude 43° for the 

 measurement of distance. For long dista 

 wholly without or wholly within the sian 

 parallels greater precision may be attained by 

 usmg the scale of miles for the average latitude 

 of the hoe to be measured.
