Why we called it Waveshed

Watershed → viewshed → waveshed: where the name comes from, and why a terrain-based RF-coverage tool earned a word of its own.

Coming soon

  • A viewshed for radio: LOS vs RF, and when to use each
  • Resolution, range, and speed: the three-way trade-off
  • ITM on the GPU vs the CPU
  • Which earth radius? 6371 km, WGS-84, and the 4/3 radio horizon
  • How accurate is browser terrain, really?
  • Buildings as obstructions: what the model includes, and what it leaves out
