Methods and systems for providing a real-time viewshed visualization

A method for generating viewshed map, comprising:

• (a) receiving a first set light source data associated with an area;
• (b) obtaining a set of point cloud data indicative of a surface feature associated with the area;
• (c) generating a shadow map based at least in part on the first set light source data and the set of point cloud data associated with the area;
• (d) receiving interactive position data, wherein the interactive position data comprises a location of a reference point in the area;
• and
• (e) generating a viewshed map visualization of the area as visible from the location of the reference point based at least in part on the shadow map and the interactive position data.

A non-transitory computer-readable medium comprising machine-executable code that, upon execution by one or more computer processors, implements a method for generating viewshed map, comprising:

• (a) receiving a first set of light source data associated with an area;
• (b) obtaining a set of point cloud data indicative of a surface feature associated with the area;
• (c) generating a shadow map based at least in part on the first set of light source data and the point cloud data associated with the area;
• (d) receiving interactive position data, wherein the interactive position data comprises a location of a reference point in the area;
• and
• (e) generating a viewshed map visualization of the area as visible from the location of the reference point based at least in part on the shadow map and the interactive position data.
