Additional Fire Focused Layers

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.

Ending Layer Licensing

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 […]

Introducing Map Sheets

We are calling this feature “Map Sheets” and it replaces the former Geospatial Images option with a lot of improvements. Map sheets are any geospatial image that can be referenced and placed on a […]
