stories from the Public Lab community
This past February at the Barnraising in Galveson Texas, we began the process of brainstorming about ways that we could equip ourselves better to respond to environmental disasters. We arranged our tools, methods and needs on a poster: a summary of which is below. Because many of the suggestions overlapped or fit into multiple categories, I've If you suggested something and don't see it, or would like to offer your own suggestions, please add your thoughts to the comments below. We'll be expanding this into a wiki page as well, and hope that folks will keep this conversation moving forward!
We'll also be looking to this list to see what kinds of environmental monitoring tools we can assemble so that inexpensive/DIY options exist. Please let us know what's missing!

Hello everyone ,
Public Lab takes utmost care in making sure that the location of a person is exposed to the extend he/she wants . Hence we here at Public Lab are working on giving people the power to safely share their location on the web .
I am happy to announce two new libraries that we are working for the past few weeks that helps in achieving this vision of ours .
In this post , i wish to introduce these new Public Lab open source software projects on Location Privacy .
Leaflet-blurred-location-display (LBLD) is an extension of leaflet-blurred-location (LBL) and does the following:
The demo is live :
1.) Shows Public Lab users location :
2.) Shows how some locations (markers) are not shown at different zoom levels :
So at Lower zoom levels , irrespective of the precision of coordinates you shared - your marker is visible on map . But as you zoom in to higher zoom levels , lower precision markers are removed .
To see details on how to use the LBLD library in your project , jump over to our github page : https://github.com/publiclab/leaflet-blurred-location-display
The red markers corresponds to coordinates [23.1 , 77.1] , [20.1 , 76.1] having precision of 1 . At lower zoom level 5**** , these red markers are visible on map .
But as you zoom in to level 6 , these red markers are removed from the map whereas other high precision markers are still visible .
According to the precision of the coordinates , different colors are given to the markers .
Precision = 0 , Blue colored markers .
Precision = 1 , Red colored markers .
Precision = 2 , Orange colored markers .
Precision = 3 , Green colored markers .
Precision = 4 , Black colored markers .
Precision = 5 , Grey colored markers .
Precision >= 6 , Yellow colored markers .
Also clicking the markers shows a pop-up telling the precision :
Greater the markers in a region , Darker the color .
We wanted to give an easy visualization power , so we implemented this grid heat map .
The default color of grid is : #F3F0C0
If number of markers are in range [1,10] , the color is : #FFA500
If number of markers are in range [11,15] , the color is : #faff05
If number of markers are in range [16,25] , the color is : #FF6347
If number of markers are in range [26,35] , the color is : #FF4500
If number of markers are in range [36,45] , the color is : #FF0000
If number of markers are greater than 45 , the color is :#8B0000
NOTE : Clicking on each rectangle shows the pop-up showing number of markers in that rectangle .
You can pass your own API link to fetch data and show it on the map . Also you need to pass a JSON parser function to parse your API . See our Github page to know more details !
This library is an independent module which gives many mathematical functions that one can use on any map (not necessary Leaflet map!) . The library is thoroughly tested using Jasmine framework .
Jump over to the github page for more details of each mathematical function : https://github.com/publiclab/blurred-location
The npm link is : https://www.npmjs.com/package/blurred-location
If you have any suggestions or any doubts regarding the use of this library , kindly open an issue here .
I personally thanks @warren for mentoring me and giving all these awesome ideas .

first-timers-onlyissues are those which are written in a very engaging, welcoming way, far different than the usual "just report the bug" type of GitHub issue. To read more about these, check out firsttimersonly.com, which really captures how and why this works and is beginning to be a movement in open source coding outreach! Beyond the extra welcome, this also includes getting such well-formatted issues out in front of lots of people who may be contributing to open source software for the very first time.
It takes a LOT of work to make a good issue of this type, and we often walk through each step required to actually make the requested changes -- the point is to help newcomers understand that a) they're welcome, and b) what the collaboration workflow looks like. Read more at https://publiclab.org/software-outreach !
Since early 2016, we at Public Lab are working to make our open source software projects more welcoming and inclusive and to grow our software contributor community in diversity and size. Creation of First-timers-only issues was also started at Public Lab near the end of 2016 - https://publiclab.org/notes/warren/10-31-2016/create-a-welcoming-first-timers-only-issue-to-invite-new-software-contributors
Now, as GSoC, Outreachy, and other outreach programs are seeking proposals for the upcoming summer, we put a lot of extra time and work into welcoming newcomers into our community and making sure they are well-supported. We've seen a huge increase in newcomers and wanted to report in about how this process has scaled!
Till now, nearly 409 FTO issues has been created across our projects which shows how many people have been welcomed in the Open Source 🌐 and in our community by the collaborative efforts of all of us.
From March 9, 2019, we started maintaining the list of people who want to work on various projects of Public Lab - https://github.com/publiclab/plots2/issues/4963 through
first-timers-only issues. And, we are proud to announce that in past 20 days, we all have created 55 FTO issues i.e., 13% of total Public Lab FTO issues(from beginning) are created in last 20 days. The growth is really tremendous and all this has been possible due to contribution of each community member.
The idea of maintaining the list of FTO issue-seekers is a big success. We have been able to assign issues to nearly 50 contributors in the past 20 days. And, each day the list is growing and we are opening more and more FTO issues for helping new contributors in taking their first-step in Open Source with Public Lab.
Those community members who have shown some tremendous support for creating FTO issues and they really ensured that there is a check mark next to the name of each newcomer: @cess @gauravano @warren @lekhidugtal @Harshithpabbati @divyabaid16 @IshaGupta18 @anan12 @sashadev-sky @madeofhuman @HarshK @Divy123 @Rishabh570 @gautami_gg
Thank you everyone for the great work and cheers to this awesome community growth 🎉 🥂 💯

We're part of two different summer fellowship programs this year, Outreachy and Google Summer of Code (#GSoC) -- both recruit software contributors to work on open source projects. We may also join Rails Girls Summer of Code (#RGSoC) once it opens, but would need to be accepted first.
We've done GSoC for a few years now, and are really excited to be part of RGSoC for a third year and Outreachy for a second season. Outreachy writes:
We expressly invite women (both cis and trans), trans men, and genderqueer people to apply. We also expressly invite applications from residents and nationals of the United States of any gender who are Black/African American, Hispanic/Latin@, Native American/American Indian, Alaska Native, Native Hawaiian, or Pacific Islander. Anyone who faces under-representation, systemic bias, or discrimination in the technology industry of their country is invited to apply.
So, we're asking students from both programs to start posting their proposals for comment, here. Read on!
Outreachy's application deadline is the March 26, 2019 at 4pm UTC. GSoC applications will be open between March 25, 2019 - April 9, 2019.
Once you've gotten a bit familiar with our project (see our welcome page here), the first step is to look over our ideas page, which you can find here. These were collected from the brainstorm we did earlier in the year.
For Outreachy, we will be posting a project idea soon on the Outreachy website.
Please feel free to ask questions in the comments below, or to join our chat channel at https://publiclab/chat
Our welcoming page will help you understand how we collaborate, and we'll be there to help you take your first step. And try tackling a first-timers-only issue, to get an idea of how to become a contributor!
Also, read this page carefully to understand our workflow and how we structure summer of code projects: https://publiclab.org/wiki/gsoc#How+we+work
Please ask questions! We're very friendly and we love welcoming new people into our community.
Once the term starts, we'll be asking all participants to review another person's work at least once time per week, and to either post a first-timers-only issue or help someone who's working on one once weekly. This will help us continue to support our growing community!
Once you've read through some of these ideas and become a bit more familiar with our projects, it's time to post a proposal of your own.
You don't need to have a complete or even concrete idea -- share your thoughts early and we'll help you refine your proposal, and help you choose something that's the right difficulty level as well as being something our project really needs.
We've created a template for you to post a proposal here. Click this button to begin:
Before or after you post your own draft, read through others' listed below. Your best comments and input may come from other applicants!

Across the Public Lab community, people are making their own maps using aerial photos (by balloon mapping, kite mapping, and the like) with the MapKnitter website - which helps people "stitch" or "knit" images into a combined map, using an existing satellite map base layer as a reference.
The core of MapKnitter's interface, the Leaflet.DistortableImage library, is seeing some new life as members of our coding community have started to dig in and make improvements! Its main goal of letting people distort aerial images to fit onto a map is being refined, debugged, and expanded. (This was made possible in part with support from NASA's AREN project)
Try it out in the demo: https://publiclab.github.io/Leaflet.DistortableImage/examples/
This takes the original full resolution image and distorts it in your browser (you may need to allow popups), and then downloads.
For example, the lead image generated this full-res distorted image: full.png (2304x1536 pixels)
See the preview below.
This may mean that for some smaller MapKnitter maps, you won't need to run a full export, which can take a while. This code should publish on MapKnitter within the next few days. Down the road, we're looking at more ways to refine the export process to make it even easier to make your own maps using balloon, kite, pole, or drone mapping.
