SPOT and InReach Evaluation

The Colorado Center Excellence for Advanced Technology Aerial Firefighting published an evaluation of satellite messaging devices in many of the environments that we encounter. They have even made the geospatial data available.

SAR Loses Another of its Own

The San Bernardino County Sheriff's Department is mourning the death of one of their own tonight. Moments ago, Deputy Lawrence “Larry” Falce succumbed to injuries he sustained from the violent attack on Sunday, December 31, 2017.

Larry is remembered as an honorable man, who began his career with the San Bernardino County Sheriff’s Department in 1981 as a deputy sheriff. Larry started his career working in corrections at the Glen Helen Rehabilitation Center and the Central Detention Center. The 36-year veteran worked patrol at Central Station for the past 32 years. Before joining our department, Larry served his country in the Army. He prided himself as being a lifelong public servant, who cared deeply about this profession.

Larry was loved by his peers and the community members he served. More importantly, he cared about so many people he called family. Larry is survived by his sister, Marjorie, and his girlfriend of many years, Deborah. He also leaves behind many extended loved ones.

The San Bernardino Police Department is conducting the criminal investigation. We will not be releasing or confirming the identity of the suspect at this time due to the active investigation. Anyone with information or questions related to the criminal investigation should contact the San Bernardino Police Department.

California Region of the MRA Comes to San Bernardino Co

The first weekend in March, the California Region of the Mountain Rescue Association, descended upon the desert in San Bernardino County for their annual reaccredition. Many thanks to West Valley SAR for organizing this year's effort. It takes a lot of time and effort to host an event that calls for hundreds of SAR team members from more than 20 teams to arrive at a single location with all of their vehicles, and related equipment. Not to mention, setting up all of the scenarios, arranging for "missing hikers", "missing evidence", food, etc. A special thanks to nearby San Bernardino teams: Morongo Basin SARVictor Valley SAR and the Barstow Desert Rescue Squad for assisting with logistics and missing people. Until you have attended an MRA reaccreditation, it is difficult to understand the amount of work that it takes to host one of these events.

 

The Cave Team, West Valley SAR, and Wrightwood SAR successfully completed their reaccreditations after tracking and locating a missing hiker, and completing an evidence search. All the while, the command post and field teams are under the watchful eyes of MRA evaluators.

 

The Mountain Rescue Association is the only nationally recognized body that accredits search and rescue teams. To be a fully accredited member, the team must complete 3 accreditations: Search Management/Tracking, Winter Snow and Ice Operations, and Technical Rope Rescue. To obtain these accreditations, prospective teams are mentored by a fully-accredited team until they are ready to test. The test is then completed by the team, and evaluated by other MRA team members from across the state. To complete a single MRA accreditation often requires multiple years of planning and preparation. For example, the Cave and Technical Rescue Team completed their technical rope accreditaion in 1999 after nearly 2 years of preparation. A few years later, the team decided to complete accreditation in the remaining two disciplines, and successfully completed them in 2006 and 2008. San Bernardino County has two fully-accredited teams (West Valley SAR, and the Cave Team), and one associate member team (Wrightwood SAR) who has completed the Search/Tracking accreditation.

Wireless File Sharing Without Internet Access

TP-Link MR-3040 wireless router. Tootsie Pop for scale.The smartphone continues to play an increasingly important role in search and rescue with all manner of apps available to assist SAR members in the field. More than anything else, I use my phone for land navigation. In fact, unless the weather is really bad, I rarely pull my dedicated GPS out of my bag. With my phone I can easily enter waypoints, scroll around on a map, and even use a decent compass. Earlier, I've mentioned specific apps that are handy, as well as ways to keep your phone powered throughout multiple operational periods, but there still remains the problem of moving data on and off the phone outside of cellular networks, and with minimal client-side requirements. Sure, it is relatively easy to provide FTP access to some command post files, but that would require that end users understand how to FTP and have the proper software loaded. This is not easily accomplished when there is no cell coverage. Enter Piratebox.

Piratebox, and its fork LibraryBox, allow file sharing outside of any internet connection. LibraryBox is a fork of the Piratebox project, and has similar functionality. The differences primarily lie in the ability to upload. Piratebox has a provision for file uploading by others, while LibraryBox is a, primarily, one-way operation; there is no provision for upload. Since it would be nice to be able to easily collect things like GPS tracks from phones, I figured that the ability to upload files would be helpful. 

There are a handful of routers that are known to work with the Piratebox software, and I chose the TP-Link MR3040 because it comes with an integrated battery, and charges via a micro USB cable. To build your Piratebox, you flash the router with new firmware (OpenWRT) that has been modified to work with Piratebox, then install the Piratebox software. I won't replicate the directions here, but I followed them on the Piratebox site, and they worked fine.

I changed my Piratebox SSID to be "SAR-Files SBSAR"When you are finished, you are able to share any files on an attached thumb drive. People access the files by connecting to the wireless router (Connect just like you would any WiFi hotspot. This one won't have internet access, though.). Once they are connected, they will be redirected to a browser window that shows a place to view files, and a box to upload files.

Landing page with customized header image and textThe whole install and configuration took about 30 minutes. I did make a few modifications, however. I modified the landing page text to reflect the use in SAR, and I changed the header image. I used the instructions from this thread to accomplish this. I changed the default SSID to "SAR-Files SBSAR" and configured file uploads to go to a different directory using the instructions on this page. Since I didn't want just anybody accessing the files on the Piratebox, I also put a password on the WiFi access using these instructions.

My goal with this project is to make .GPX/.KML files for all search assignments available for download to searcher's phones. Also to be included are PDF maps and other documentation such as photos, track prints, etc. So, rather than getting an assignment, and spending time entering in waypoints and such, the searcher can quickly download his/her area to include on the mapping program on their phone (Backcountry Navigator, Locus, Gaia, etc). The command post would load up the flash drive with the files, plug it into the Piratebox, and set it on the check-in table for SAR members to access at their leisure. 

When the team returns, and has tracks and/or photos on their phones, they can connect to the Piratebox again, and upload their files. Later, the command post can pull the thumb drive and download all the files uploaded by the teams. Since everything is done with a web browser, no special software needs to be installed on the end-user's phone. This is key. Any solution that is designed to work outside of internet access, can't require a special app download since there will be no way to download the app without prior planning.

I have yet to try my Piratebox on an actual search, but it won't be long before the call arrives, and I will be able to give it a whirl. I will continue to update the links that I have found useful with this project at https://pinboard.in/u:jlehman/t:Piratebox. All of the links mentioned in this article are there. Drop me a line if you have any questions.
