I’m a little confused by your question. LIDAR data is going to show you line-of-site locations which is not what TVWS gear is best used for servicing.
LIDAR data only makes sense in identifying the areas you can’t serve with other gear. I suppose it gives you a ’negative’ view of the area to identify area you might want to serve with TVWS.
