a colleague and I try to analyze the visibility of wind turbines from several places in ArcGIS Pro.
In a first step we constructed “sight lines” by using the tool “Construct Sight Lines“between our observation points and the wind turbines (see figure 1).
Afterwards we tried to analyze the visibility of the wind turbines from our observation point by using the „Line Of Sight“ tool. We inserted the following datasets:
- „in_surface“: a Digital Terrain Model
- „in_line_feature_class“: the mentioned sight lines between the observation point and the wind turbines
- „in_feature“: a multipatch-feature of buildings
As you can see in figure 2 the output is just a single, uncut line, which crosses the multipatchbuildings.
We also tried to use as “in_surface” a Digital Surface Model and didn’t enter any “in_feature”. The result was a distorted line in a far too high position (see figure 3).
Our last idea was to cut our generated “sight lines” from figure 1 manually by deleting vertices or cutting lines on the points where they are touching the multipatch buildings. But the selected lines were moved upwards so that they are not touching the building anymore as you can see in figure 4.
Can someonehelp us with some proposals to solve our issues?
Thank you very much in advance!
