Circum Posted October 30, 2002 Share Posted October 30, 2002 An interesting quirk... The altitde of the Sandy Hook Lighthouse Finial is listed at 2ft. The Sandy Hook Lighthouse Light is listed as 3ft. Presumably, the light is near the top of the Lighthouse which is 103 ft. from bottom to top and the finial is on the roof, above the light. Since both are listed as Second Order Horizontal controls, I assume the altitude is actually a "don't care". Why though, do they bother to list an altitude, which is obviously incorrect for the light and finial? Quote Link to comment
+rogbarn Posted October 30, 2002 Share Posted October 30, 2002 I almost always see no altitude listed for these landmark type of benchmarks. All I can guess is that they are listing the ground level even though the point being used is 100+ feet in the air. But what I find most interesting is that there are over 30 benchmarks listed within a mile of the flagpole. Anyway want to add to their numbers quickly?? Quote Link to comment
survey tech Posted October 30, 2002 Share Posted October 30, 2002 Thats correct, while some points have precise horizontal and vertical data most have only one or the other. Quote Link to comment
