|
Mean Seal Level is a tidal datum that is arithmetic mean of hourly elevation observed over a specified 19 year cycle.
|
|
What does MSL average out?
|
It averages out tidal highs and lows caused by the chaining effects of the gravitational forces of the sun and moon.

|
|
What impact does shadow have on target marker placement?
|
Shadows can help identify what you are looking at.
|
|
What impact does light have on target marker placement?
|
Washout (too much light) can inhibit image resolution
|
|
What impact does image angle/obliqueness have on target marker placement?
|
Obliquity and error can skew the coordinates of an image increasing the search time in terrain recognition.
|
|
What happens with look angle adverse and obliquity in mountainous terrain?
|
In mountainous terrain, look angle adverse and obliquity can be challenging
