View analysis: what viewshed means
Viewshed calculates which areas are visible from a point; it turns view quality from a guess into a map layer.
Views are often described subjectively: sea view, valley view, forest view. Viewshed analysis turns that language into a spatial layer. From a selected point, it calculates which areas can be seen according to terrain and which areas are blocked by the land surface.
First check: photo or field of view
A photo shows only one moment and one angle. Viewshed reads the terrain surface. Visibility can change for a cabin, house, terrace, lookout point or security camera because each has a different viewing height. A view decision should not rest on one frame.
- Place the viewpoint at the real use location; the center of the parcel is not always the right point.
- Read aspect and slope together; a good view is not always the same as good sun exposure.
- For privacy, think not only about what you see, but also where you are seen from.
- Remember that trees, buildings and seasonal vegetation can change the practical result.
A view is not a sales claim, it is a placement input
Viewshed does not declare a parcel more valuable. It strengthens placement decisions instead: where a building should sit, where open space should remain, which angle matters in a marketing video, and where visual contact with neighboring parcels appears. View quality enters design and presentation as data.
Soft boundary statement: Parselo does not present viewshed output as valuation, development right or official view guarantee; it shows it as a decision-support layer based on the terrain model.
Where Parselo uses it
Parselo Eco uses viewshed logic for view and privacy decisions, Urban uses it for building placement and amenity reading, and the video layer uses it to choose stronger presentation angles. The same analysis gives both design teams and sales presentations a clearer base.
