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 […]

GOES Live Fire Detection Layer

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 […]

Summer Wildfires

Note: This post was updated on 9/11/20 to include information about the GOES Live Fire Layer as well as the GOES Live Satellite Imagery. We also attempted to address some of the most frequent questions we’ve gotten over the last few weeks in our help forums. With the increase in wildfires across the Western US […]

Beta Testers

As our app has evolved we are moving away from the our mass beta test and into a more stable update cycle! What does this mean to our users? More regular, stable, incremental releases with features and bug fixes as well as a much more polished app than 1 year ago. It also means that […]

Introducing Map Sheets

Today we’re taking a major step forward with improved support for local data that doesn’t fit well into our nationwide layers. 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 […]

SARTopo Training Opportunities

As many SAR teams are using online and remote trainings to maintain physical distancing, CalTopo is offering a free, 2-hour SARTopo webinar training. This training is designed to help search and rescue personnel get started using SARtopo to create effective maps for planning and executing missions. Specifically the training will cover the following items: 1. […]

Parcel Data

We’ve made a few changes to map layers including a major new addition! We’ve added a parcel overlay for the US. This data set contains property boundaries and addresses (left image) for a majority of the US, and ownership information (right image) for many of those properties as well. This new overlay is live now […]
