Aerial photomap of Belize Open Source

I flew the Mavic Mini around the property at 400 feet (~129 meters).

At Belize international Airport I had WiFi and was able to upload the images from my laptop to Drone Deploy’s cloud-based software which processed 486 photos to make an orthomosaic map and 3D model. Here is a screenshot from my phone.

Leaving Gamboa, Panama

I’m was at Canopy B&B, waiting for ride to airport. Now I’m in line at the airport.

I had great time here. I came to visit Andrew Quitmeyer, at Digital Naturalism Laboratories (DINA: https://www.dinacon.org) via invitation from Shannon Dosemagen, long-time Public Lab friend. You can see what Public Lab is about at: https://publiclab.org/

I’d been intrigued by a map and 3-D model of Gamboa that Andy had made from a drone flight. I brought my new Mavic Mini that I had maybe 6 min of flight time with. Andy coached me, and we flew a section of Gamboa Marsh where a music festival had fumigated and dumped a load of gravel inappropriately. So it was a live, real use case. We took over 300 photos, at 2-second intervals, from 100 m, flying manually.

We started a map in Mapknitter, then I used Drone Deploy’s trial offer to make a map and 3D model.

Andy also introduced me to Andrew Coates. His firm Cresolus (http://www.cresolus.com/) specializes in architecture and construction in the tropics. We were able to talk briefly and he’s interested in helping come up with an open source design with very simple IKEA-like instructions for building houses that might be used at the Belize Open Source – Sustainable Development site. It is convenient that he is already working in Belize for a government of Belize project funded by World Bank, to renovate a repurpose an old forest station with ~ 40 buildings, on the way to the Carocol Mayan ruins. He’s also renovated the facilities at The Thousand Foot Falls in the mountain pine ridge area of Belize. Andrew had great ideas about how one might approach this similar to a boat building company out of Chesapeake Bay. They offer

kits that you can buy and make yourself

classes where you can come and learn and build your own

or they build and deliver to you

Andrew talked about his Panama hut initiative which has trained builders to fabricate and then be able to flat pack and send the small very nice units. See: https://www.thepanamahut.com/

I emailed Andy and Andrew that I was sure glad we were able to chat for a few minutes. Very productive!

I sent a PDF of the dual vault composting latrine design package, as well as the bill of materials, for the ones that we’ve been doing for ~ $415 per unit cost in Nicaragua (111 to date, with another Rotary global grant nearing approval to do 80 more in seven communities.)


I also sent link to the drum-based composting toilet system I spoke of separately.


I stressed I appreciate what Andrew is doing and the opportunity to try and partner on a vision for the little Belize place.


I think the open source construction manual, training workshops, sponsorship for the local Belizeans to become certified builders, all really sounds terrific.

After, Andrew wrote, “Good to talk to you.I love the idea of creating a simple tropical home that is kit built from an “IKEA” guide. Available to all.”

I also used another cloud based software to process a test set of photos from our El Llanito, Nicaragua water supply aerial image contractor who flew tests from up the hill to sector 5 in the community, just reaching our areas of active trenching (visible on far right side) in this scaled small sample aerial map. The preliminary results are encouraging for being able to map our project.

Phil Bowman, our responsible engineer in charge (REIC) indicated winds that stopped them have stayed too high, so they will coordinate with EWB Nica Country Office and the water committee (CAPS) on when to return.

Phil and the team have continued to make great progress on the well support building and other tasks.

We were able to coordinate with Martin and Maribel today on trench digging. Our UC Berkeley chapter colleagues were assigned a stretch of trench to dig near Zeleyda’s house

On our way to Nicaragua

We’re on the Avianca flight from SFO, with stop in San Salvador, due into Managua a little after 9am.

We will have two teams of six people, traveling for about a week, with couple days overlap, returning 18. January, to get started on this project. Our travel teams will include UC Berkeley students who are participating in the project.

I am also bringing water filters from Darrell Ward, a Rotarian from Oklahoma. He’s been working with Alcance And the Rotary Club of Masaya to distribute them to communities who need them

I’m also bringing Foldscopes for a person at the University of Nicaragua.

We will have two teams of six people, traveling for about a week, with couple days overlap, returning 18 January, to get started on this project. Our travel teams will include UC Berkeley students who are participating in the project.

In addition to constructing a small well-support building, we will be training and documenting proficiency of community members to trench, install pipe, pressure test, backfill, and construct other elements of the system including pressure break tanks, and tap stands.

They will continue on these tasks after we leave. In this visit, the team and community will be laying out and flagging the ~3.5 km distribution system

We then plan to return in the March timeframe to complete and commission the system.

Some of the photos and the diagram of the distribution system give a sense of the place. these in Nicaragua

About $15k worth of materials have been purchased, and deliveries are under way.

Guest writer

My friend Peggy Schimmelman was gracious to feature a short piece of mine on her site. It’s set in Belize.

Thank you Peggy.

Public Lab/citizen science

I’ve been involved with Public Lab (and Grassroots Mapping) since 2010, when I wrote to Jeff Warren after seeing the diydrones post showing his map of a settlement outside Lima, Peru. 

Public Lab is doing a Kickstarter campaign for aerial photomapping kits, from small lifting kites and balloons to the classic larger ones.

Jeff, Stewart Long, Mathew Lippincott, and others in the Public Lab community helped me learn simple aerial photo mapping techniques. 


They also helped me start a grassroots mapping program to map the 40-acre Belize Open Source – Sustainable Development (BOSSD) site at high resolution to support site development work and progress reporting, to make this methodology accessible to local landholders, to engage schools to develop capabilities for educational and community mapping and make an initial set of maps.

I’ve presented at Engineers Without Borders (EWB) workshops and poster sessions on Simple, Inexpensive Aerial Photomapping


In 2013, I applied these techniques at the BOSSD site and sessions at the August Pine Ridge RC school and Muffles College.

I’ve not been as active with Public Lab due to other priorities, but I am looking to get back to it.

CWC TVW Critique groups run year round

At our last meeting of the California Writers Club Tri-Valley Writers Branch this season, President, Patricia Boyle, asked me to speak about our STEM critique group.

I was happy to. As my members page indicates, in part:

Patrick D. Coyle journals and writes memoir and personal stories about travel and sustainable development. His short memoirTime of Your Life, won first place in Impressions, the Las Positas College 2015 anthology.

Other memoirs have been published in the Voices of the Valley: Word For Word, Encore, and First Press, California Writers Club Tri-Valley Branch anthologies (2015, 2013, and 2011); 4th Street Studio’s Livermore Wine Country Literary Harvest and Saturday Salon Literary Harvest anthologies.

I’ve been involved in critique since I joined the Tri-Valley Writers Branch in 2005 as a charter member. My good friend and mentor, Hector Timourian, led this group until he he handed it off. I picked up the responsibility to “clerk for us,” getting the announcement out to people about when the monthly meetings are coming up, letting people know who has submitted pieces, and showing up to facilitate the critique session discussion.

I’ve benefited from the feedback from others, reading the diversity of others pieces, and offering comments about what I liked, what gave me pause, and suggestions.

The monthly critique sessions also encourages me to write, to get a piece ready to submit for critique. I don’t like to be empty handed.

I joke with others that my only hope is that writing is a learnable craft.

We continue the STEM critique group through the summer.

I encourage you to write, to check out our CWC TVW branch, and to consider the critique groups as a way to improve your writing.
