Astronauts on board the International Space Station (ISS) take hundreds of night-time pictures each year of cities around the globe. Cities at Night is a “citizen science project that aims to create a map, similar to Google maps, of the Earth at night using night-time color photographs taken by astronauts onboard the ISS.” Check out the photographs that have been geo-referenced to the Earth, or join in and help the project team geo-reference new photographs!

Burbank received the LARIAC5 2017 imagery and I must say it looks great! Click to enlarge.
Also, this time around the imagery has 4 bands, band 4 being near infrared, so you can display color infrared (CIR) to make the vegetation pop. Just set the Red band to 4, the Green band to 1, and the Blue band to 2:

Back in August 2015 I posted information about how you can extract features from a map service. Since then, I have had many contact me about modifying the code so it can extract features beyond the record limit set in the map service. So today I decided to work on one that does!
To test the script, I headed over to the map services provided by the State of California GIS. Specifically, the one for wildfires:

The USGS Library provides reference services and instructional sessions to library users on finding print, digital, and online library materials. They are offering two webinars.
The first will focus on how to find and use information sources and products related to water use, surface water, groundwater, water quality, floods, droughts, and hurricanes (data, databases, publications, maps, and field and laboratory methods). Click here for more info and to register.
The second will focus on how to find and use information sources and products related to long-term and short-term land changes from natural-hazard events, land-use change, and example reference inquiries related to finding current and historical land information. Click here for more info and to register.
Both webinars will also cover education tools available from the USGS and other geoscience stakeholders.
