Onx vs. Trails offroad vs?

[KC Masterpiece]

Wait a minute…. Explain “daily satellite imagery.” So if I am camped for 2 nights, by night 2 I see my truck?

It is daily imagery updates but the resolution is no where near good enough to see something that small. I find it very useful in the spring for determining snow coverage. It is definitely not like having your own access to a spy satellite. There are also weekly images available in a better resolution but you are always running the risk of cloud coverage.

I use Gaia as my map system and trails offroad for tracks and way points uploaded to Gaia.

Base Map


NASA MODIS over past few days. Clear days show snow coverage (note slight change between 17th and 23rd in valleys) and a cloudy day on the 21st. All the satellite layers are shown at 50% so it's not an accurate representation of overcast on the cloudy day.

But to give you some idea of resolution I put a view at 62,500 scale over the Forest Service topo around Georgetown and Loveland. You can get a sense of snow coverage but you're not going to be able to tell the exact day when a trail clears. Each daily satellite pixel on that image is about 750' x 750'.
