We are frequently asked about our maps, their accuracy, and the accuracy of tracks, routes, and lines. This is part one of a two part series to help explain some of the nuance in mapping. Inherently this can be a bit of a dense topic so we’ve broken it down with some clear sub topics […]
We’ve just launched two more fire related layers. The first is a false-color visualization based on the Sentinel weekly high-resolution layer. By using Sentinel’s upper infrared bands, we discovered that we were able to provide a clear picture of burned areas and active hot spots, even when the visual imagery is entirely obscured by smoke. […]
We just added live satellite imagery from GOES 16 and 17: https://caltopo.com/map.html#ll=40.07807,-113.81836&z=6&b=mbt&o=goes_0&n=1 CalTopo has a dual mission. Normally, we try to be “the right tool for a good day”, helping you plan and execute amazing adventures in the backcountry. Sometimes, particularly for professional users, we become “the right tool on a bad day”, helping provide […]
CalTopo has always made its map layers available to other apps and websites, but we’ve decided it’s time to phase that out. Our slope angle shading layer will no longer be available outside of CalTopo on Oct 1, with all other layers no longer available in other apps and sites in January 2021. We know […]
In response to the recent California fires, we’re launching a new, highly experimental layer: live fire detections from the GOES 17 (West) satellite. GOES 16 and 17 are geostationary satellites positioned over the eastern US (16) and western US (17), streaming images back to Earth on a near-real-time basis. You’ve probably seen their imagery used […]
