If you are a SkyTruth Alerts subscriber, you may have noticed that there have been no new NRC reports lately. This is because the NRC has not published any new reports since November 18. We’ve contacted them to try and find out what’s going on, and we’ll have them back in SkyTruth Alerts as soon as we can.
For the last year or so we’ve been working to revamp SkyTruth Alerts, an app we built for ourselves in 2011, and then opened up to the public a year later. The Alerts lets you see environmental incidents and notifications on a map as they are reported, and allows subscribers to sign up to receive email notifications about reported environmental incidents in areas they care about (aka “Areas of Interest” or AOIs). Technology has made a few leaps since then, so it was time for an overhaul. We’ve added some new features too. We’re excited about the changes, and we hope you will be too.
In a lot of ways, the new SkyTruth Alerts app works the way it always has: anyone can view the map and see the latest reported alerts for a particular area. These notifications come from federal and state websites that we have “scraped” to obtain the reports. The largest source of data is the nationwide oil and hazardous materials spill reports collected by the National Response Center (i.e., NRC Reports). Anyone can sign up to receive email notifications about incidents in their AOIs.
New and Restored Sources of Alerts
As part of the Alerts revamp, we’ve restored and/or added the following sources of alerts:
- West Virginia oil & gas drilling permits – restored
- Colorado oil & gas drilling permits – new
- Florida Pollution Reports – new
We’ve also added account management so you can update your AOIs or change your email address more easily. Signing up for an account will also let you take advantage of new tools we’ll be rolling out in the coming months (we’ll keep you posted after the launch).
This is what SkyTruth Alerts looks like right now:
This is what you’ll see when you first open the revamped SkyTruth Alerts (subject to some possible changes over the next few weeks, as we respond to feedback and suggestions from our alpha testers):
Here are a few of the new features we’ve added:
New Ways to Create AOIs
Right now, SkyTruth Alerts lets you create AOIs that are a square or rectangle, but that’s not always the ideal shape. In the new version, we’ve added some tools that give you a little more control: you can draw a polygon, take a “snapshot” your current map view, or select a state or county boundary from a list of pre-defined AOIs):
After you create an AOI, you can edit your AOI (or delete it and start again) before giving it a name and saving it to your My Areas list.
Filter Out the Noise
We’ve added several ways to filter what you see in Alerts, so that you can focus on what’s important to you. SkyTruth Alerts shows you the 100 most-recent incidents in your map view (double what’s shown in the current version), so filtering has the added benefit of showing you more of the types of alerts you want to see. You can filter alerts by:
Type of Alert
Select from a couple of different map backdrops (“base layers”) so you can focus on what’s important to you. Below is a screenshot of SkyTruth Alerts using the “Minimal” base layer.
Alerts Within AOI Only
This can be useful if there are a lot of alerts in the surrounding area that are more recent than the alerts within your AOI.
In the image below, there are only a few alerts are shown in the West Virginia AOI:
However, once alerts are limited to within the AOI, the picture changes:
New Ways to View Alerts Markers
In some places, there are many, many alerts in the same location. This can make it hard to move around the map because you end up clicking or tapping an alert marker when you wanted move around in the map view. It can also be hard to “grab” a particular alert marker from a stack of them.
In the first screenshot, clustering is turned on, making it easier to move around the map. Click on a cluster marker to zoom in on that area and see more alerts.
Once you’ve zeroed in on your area of interest, it can still be hard to see the forest for the trees in some locations. In the next image, clustering is turned off. You can see that there are a lot of alerts in this area, but how many exactly?
The image below shows the same area as the one above. If you click on one of the alert markers, it will “explode,” showing you all of the alerts in that location. Click on any of the exploded markers to view the report.
So when’s the Launch?
We’re getting ready to begin alpha testing in in mid-November. Lots of our current subscribers have volunteered to be testers and will be helping us put the finishing touches on the app. A big thank you to all of you who are helping us with that! Testing will last four weeks, and during that time we’ll be making continuous updates based on feedback we receive. We expect to go live with the new version by the end of the year.
