Creating horizon line

Michele

Hello,
I was wondering if it's possible in some way to create a list of points describing the horizon line as seen from a specific point based on terrain data. It should be a list with a column of azimuth values and a column of angle values where the angle is the one at which you can see the sky over the terrain.
Example:

-180 1

-175 1

-170 1

-165 1

-160 1

-155 0

-150 0

-145 0

-140 0

-135 0

-130 0

-125 0

-120 0

-115 0

-110 0

-105 0

-100 0

-95 0

-90 0

-85 0

-80 0

-75 0

-70 0

-65 0

-60 0

-55 0

-50 0

-45 0

-40 0

-35 0

-30 0

-25 0

-20 0

-15 0

-10 0

-5 0

85 4

90 5

95 6

100 6

105 7

110 7

115 7

120 7

125 7

130 7

135 7

140 6

145 5

150 3

155 2

160 2

165 2

170 1

175 1

180 1
The sampling for this calculation should ideally be 1 degree for both columns. Also a scripting solution is fine.
Any help in this matter is welcome,
Thanks and best regards.
