What does a red line on a line of sight graph mean?
A red line indicates a line-of-sight that is blocked while a green line indicates a clear line-of-sight between the points. After the initial graph is created, the users will have the ability to modify the graph by specifying heights for the antennas. As the antenna height changes, the path will recalculate to determine line of sight.
How does the line of sight work for SCADA?
RF Line-of-Sight provides radio path information for mapping long distance SCADA radio communications by using antenna height and topography.
How to calculate the RF line of sight?
RF Line-of-Sight. This free online tool takes antenna height and the topographical formations of the earth to calculate the line-of-sight of a radio path. This RF Line-of-Sight tool is exceptionally helpful in mapping long distance radio communications for remote monitoring applications such remote shutdowns and data acquisition.
Which is the correct equation for stopping sight distance?
Therefore: Stopping Sight Distance = 1.47Vt + 1.075V2 / a (2011 AASHTO, Equation 3-2, 3-4) Or simplified: SSD = 3.675V + 0.096V2 When the highway is on a grade the braking distance is increased and the equation is modified as follows:* Braking Distance = V2 / [30((a / 32.2) ± G / 100)] (2011 AASHTO, Equation 3-3, 3-5)
Can a straight line be set out between two obstacles?
Sometimes, a straight line has to be set out between two points (A and B) which are one on each side of a hill, dyke or any other high obstacle (see Fig. 14); standing at point A it is impossible to see point B. A procedure by trial and error is used, which requires two observers and one, or preferably two, assistants.
Which is the best definition of a straight line?
2.1 Definition of a Straight Line. A straight line is the shortest distance between two points on a map or between two points on the field (see Fig, 9).
