Starting to leave San Francisco. Photo is of Bird Island in the Marin Headlands. 39.1 unique miles.
Cases and Deaths by Country Yesterday
Cases and Deaths by US County Yesterday
This post is updated daily with global and US county level coronavirus data from Johns Hopkins University. Four videos show both cumulative and daily progression of the disease together with four images that show a snapshot for yesterday.
Cases and deaths are shown simultaneously using blue for cases and red for deaths. Where both are high a region will be a shade of purple. Regions with no data are dark gray.
The daily incremental visualization is useful to see the history and current state of the spread of coronavirus. Each region is shaded based on the highest number of daily cases and deaths for that region. For example if the highest number of deaths reported on any day in San Francisco county is 3, then any day that has three deaths will be the brightest shade of red. This shows where COVID-19 is relatively bad but should be used to compare regions.
The cumulative visualization is shaded relative to the highest total death and case count for any region. This does show the relative severity between regions (based on total deaths and cases, not relative to population).
As the location and date of the peak in daily and cumulative cases and deaths change over time the videos will be different each time you watch. Bookmark this post and check back for daily updates.
(This is the third version of this post as I have changed the data source and methodology several times. I usually preserve the previous version of any post but the changes are large enough that in this case I have removed them).

Cases and Deaths by US County
37.2 unique miles in May. Photo is the fog shadow behind Grand View Park.
36.4 unique miles in April (I'm not using the GPS for repeat hikes). Bagged Twin Peaks, wider paths than Mount Davidson.
Not getting far from home any time soon so all hikes for now will be local. I found a great web app, Routeshuffle, that will generate a random hike from the starting location of your choice. It's a great way of seeing streets you'd never venture down normally. The map is generated with some software I wrote to combine multiple KML files for easy rendering in Google Earth (oh, and Google Earth, I guess that does the heavy lifting). I'll post these every month while we're locked down. March is 15.6 miles total.
