Community Mobility Reports

Check out Google’s Community Mobility Reports that provide insights into how people’s movements in countries around the world were altered during the lock down period of COVID-19.  Also you can see mobility change since countries have eased movement restrictions.

The reports use aggregated anonymized data from mobile phones to chart trends in movement over time.  They show how visits to different venues (like retail, groceries, parks, transit stations, etc.) have been effected by government lock downs.  Check it out!


An overview and how to understand the data can be found here.

Huntington Digital Map Collection

The Huntington Digital Map Collection is an internet catalog of over 8,000 maps of California and the World from The Huntington Library, Art Collection & Botanical Gardens.  The maps range from 16th century European portolan charts to 20th century land use maps, including maps owned by British explorer Sir Richard Burton; the Solano-Reeve collection of surveys of Los Angeles and Southern California tracts; and printed tract maps from the Rare Book Collection.  You can see all of the available maps in the Huntington collection with thumbnails and short descriptions so you can easily choose the ones you want to view more fully.  Check it out!


Neglected Dam Map

Thousands of people in the U.S. may be at risk from dams that are rated in poor or unsatisfactory condition.  An Associated Press investigation has identified at least 1,680 dams in 44 states and the U.S. territory of Puerto Rico that are considered to be high hazard and in poor or unsatisfactory condition.  A dam is listed as high hazard if its failure is likely to result in people being killed.  The dams and their date of last inspection have been plotted on an interactive map.  Looks like there is only 1 in California.


US Flood Risk Map

A new online flood risk map has been released by the nonprofit organization First Street Foundation.  The online tool can tell you the current flood risk for your home and possible future risks.

The flood model used by Flood Factor is based on models of flood risk from rainfall, overflowing rivers high tides, and coastal storm surge.  It takes into account such as factors as flooding history, elevation and proximity to water.  To predict future risk of flooding other factors are also taken into account, such as different climate models and predicted sea level rise and predicted future precipitation patterns in the local area.  Check it out!


COVID-19 Trends for US Counties

While we slowly open up again, there is that looming possibility of a COVID-19 second wave.  Data analysts have been crunching the numbers to see if they can identify any signs of a pending resurgence.  Check out this interactive map that shows daily data by US Counties, which include trends, days since last new case, recent outbreaks, active cases per 100,000 people, mortality rate by trend, deaths per 100,000 people, deaths as % of total cases, and state summaries.


Forest Inventory & Analysis Factsheet

If you are interested in exploring forestry statistics in your home state, you might enjoy the Forestry Inventory & Analysis Factsheet.  The resource provides “a brief overview of forest resources in each state based on an inventory conducted by the FIA program in cooperation with each State forestry agency.”  Factsheets were created using data from the USDA Forest Service’s Forest Inventory and Analysis database.  To explore the data, toggle over the map and click on a state, or use the dropdown bar in the lower left-hand corner to select a state from the alphabetized list.  Check it out!
