An example: Being able to model RF propagation in three dimensions for a
|
|
metro area when deploying wireless networks. By having every single tree
|
|
and building detail and similar, you can "see" even tiny dead spots due to
|
|
physical blockage and signal attenuation. Overlay this with fiber map data
|
|
for yourself and your competitors (when you can glean such data), which is
|
|
also useful at this resolution, and you have a very slick way of modeling
|
|
existing network deployments in excruciating detail and optimizing further
|
|
deployments to maximize coverage and bandwidth. Take that and tie it into a
|
|
slick geo-physically aware real-time network monitoring and management
|
|
system and you've really got something...
|
|
|
|
For many applications though, 5-meter data is probably adequate.
