The Chinese space station Tiangong-1 was launched in 2011. It stopped communicating with ground control back in March 2016. With no way to bring it down into a controlled descent, it is now slowly falling closer to Earth’s atmosphere. Scientists have only been able to wait for its orbit to decay and now it’s expected to tumble to the ground or ocean in the next few days.
Both amateurs and government agencies are trying to figure out where and when it will arrive. Some sites like SatView are running live streams of Tiangong-1’s current location and predict where it might fall to Earth.
The most current prediction at the time of this writing is Monday April 2 at 01:05 UTC. Check it out!
Use ArcGIS Server? Want to edit data out in the field with disconnected editing capability but don’t want to be forced into the ArcGIS named user model just to use Collector? Webmapsolutions.com might have an answer for you! They have built an offline-enabled ArcGIS data collection app which works with ArcGIS Server (no named user required), but can also work with Portal and ArcGIS Online! Check it out.

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:
Very cool. Great job LA County! -mike
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:
When you scroll down a quick look will reveal that there is a maximum record count of 1000:
The California Earthquake Hazards Zone Application (“EQ Zapp”) is an online map that allows anyone with a computer, tablet, or smartphone to conveniently check whether a property is in an earthquake hazard zone. Earthquake hazard zones include fault rupture areas, liquefaction areas, and earthquake induced landslides. Check it out!

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.
