The Concise Introduction to the OpenStreetMap Project

Speaker: Steven Johnson

For those who know nothing about OpenStreetMap, this five minute introduction will feature a brief history of OSM, how it works, and the significance & impact of the project worldwide.

10 Years of OSM in the Classroom

Speaker: Richard Hinton

In this lightning talk I’ll present the why, how and results of incorporating OSM in the curriculum of GIS classes at George Washington University. Introducing OSM into the GIS classes was part passion for the instructors and part exposing students to a non-proprietary means of data creation and application in the context of humanitarian efforts.  Many of the initial challenges have been abated with new technology over the last 10 years, but some still persist.  This short talk will briefly talk about our origins, the incorporation of OSM, what outcomes have emerged and issues that continue.

The Latest and Greatest from Mapillary

Speaker: Christopher Beddow

Mapillary is the platform that makes street-level images and map data available to scale and automate mapping. With nearly 1.5 billion images and waves of recent change, we have many new things to discuss in 2021: the new API, an updated website, improved OpenStreetMap tools, expanded focus, and upgraded camera compatibility. Join us to learn more about the current state of Mapillary, whether you are a longtime user looking to get the same great features or a new user wondering how Mapillary can help you make better maps.

Florida : State of the (Conservation) Map

Speaker: Valerie Anderson

Florida's roads & cities are fairly well mapped, but the conservation lands, trails, forests, grasslands, scrubs, sandhills, & wetlands are generally sparse in OSM. From 1990-2008, Florida had one of the best land protection programs in the state & has protected ~2.5m ac, most publicly-accessible properties of high recreational value. Since 2008 the program has been basically defunded & existing conservation land is facing threats from direct & indirect development pressure & other human impact. Mapping Florida's conservation land & environ helps people discover its value & act to protect it.

Using high resolution topography to update OSM

Speaker: Emmor Nile

In the last 20 years there has been a tremendous growth in the use of lidar technology to develop surface models of the earth and vegetation. The State of Oregon has a WMS service that can be used as a base in the OSM iD editor as well as JOSM. This presentation will cover how lidar surfaces are created and how to use them to improve the accuracy of OSM.

The Daylight Map Distribution

Speaker: Jacob Wasserman

The Daylight Map Distribution (www.daylightmap.org) is the result of Facebook’s process to build an OSM dataset corrected for vandalism, profanity, and other harmful edits. We publish a planet PBF every 4 weeks to S3 for anyone to use that may be worried about exposing their users to these harmful edits. This is the same dataset Facebook uses in its widely published basemap. We also release OSC “sidecar” files that add ML-derived roads and buildings to the map. This presentation will describe how we create the Daylight Map dataset and the types of harmful edits we try to protect against.

3:00 - 3:45 pm ET
Using OSM to Quantify Local Economic Disparity Resulting from Traditional Racial and Class Segregation

Speaker: Willem Lee-Stockton

Lubbock Texas's history of racial and class segregation has modern impacts. Texas Tech YouthMappers and a local NGO apply OSM to further quantify local inequality and disparity. We hosted a 3-day livestream map-a-thon, part of our twitch.tv mapping series. We are also mapping disparity in our greenspaces on OSM. Inaccessibility to greenspace has lasting social, biological, and economic impacts to communities. We are identifying and tagging individual trees with species wikidata using FieldPapers, to examine species diversity. This work aids in policy decisions directly impacting our community.

Microcosms in OSM

Speaker: Brian DeRocher

Microcosms supports the activities of local groups of volunteer mappers. Learn how it can support your team and help you create one.

Mapping USA's History on OpenHistoricalMap

Speaker: Jeff Meyer

We will showcase the progress of the OHM platform for use in historical mapping, focused on US history-related topics. We can talk about any scale of project or focus, with an emphasis on supporting storytelling and enhancing and building a larger historical dataset.|-

Supporting and Engaging Community Groups and Contributors to Leverage OSM Data and Tools for Positive Social Impact

Speaker: Arnalie Vicario

We believe that an improved community is one which collaborates to achieve goals, and which fosters and supports the growth of other local groups around the world. In this lightning talk, we will talk about initiatives and projects of local communities and contributors that the Community Working Group support, such as promoting and celebrating community/contributor achievement and successes, and conducting community webinars to provide open and inclusive spaces for dialogue and discussion with the global open mapping community.

Welcoming New Mappers

Speaker: Clifford Snow

Studies have found that welcoming new users to OpenStreetMap help improve retention. This talk will demo a website that allows anyone to welcome new US mappers. The demo tool tracks who has been contacted and if they responded and makes sending welcome messages easy as copy and paste.

Fostering a Mapping Community in St. Louis

Speakers: Matthew Gibb, Dr. Freddie Wills, Dana Stuckey

In March 2020, Harris-Stowe State University partnered with Maxar and other organizations local to St. Louis, to introduce students to careers in the geospatial industry. At our event, we focused on mapping several neighborhoods in downtown St. Louis, identified as priority communities through St. Louis' GeoFutures Strategic Roadmap. Future opportunities to improve the map and utilize OSM data in St. Louis are in the works! This talk will highlight this event and help us draw attention to a new group of mappers in St. Louis!

Integrating OSM into an undergraduate cartography curriculum

Speaker: Bill Wetherholt

This talk provides a brief overview of introducing cartography students at Frostburg State University to OpenStreetMap since 2019. Attention is paid to rationale, initial lesson plans, student impressions, and future directions. A warm reception by students has the potential to mitigate Western Maryland’s OSM deficiencies as well as provide students that struggle with more technical lab exercises an inroad to mapping that resonates with them.

4:00 - 4:45 pm ET
Road Quality Trends in the USA, 2018-2021

Speaker: Monica Brandeis

Critigen’s OSM team developed the Map Quality Measurement (MQM) process to rate and rank the quality of OSM data in cities throughout the USA. In 2019 we analyzed roads data for 51 major US cities and published our findings on osmquality.io. Building off this work are using the MQM process to analyze trends in road data from 2018 - 2021 in a select number of cities. Which city’s data has improved the most and which have gotten worse? Where in the city are the most errors concentrated? Which features are most affected? Our team will answer these questions plus more at Mapping USA 2021.

Mapping Community Connections: Hudson Valley Mappers' Work in Poughkeepsie

Speaker: Benjamin Bachman

Hudson Valley Mappers (HVM) is a local chapter of YouthMappers, a project of the USAID GeoCenter. HVM is based at Vassar College, and most of our projects focus on mapping in our community, the City of Poughkeepsie, NY and the wider Hudson Valley. For this lightning talk, we aim to share some of the work we've engaged with in the last year. In particular, we will highlight our work with youth through the Dutchess County No Child Left Inside (NCLI) program and our work with Hudson River Housing (HRH), an affordable housing group in Poughkeepsie.

University Education and OpenStreetMap - Creating Service Learning Opportunities

Speaker: Tom Mueller

OpenStreetMapping is easy and requires little GIS knowledge.  This makes it the perfect tool to incorporate into classes. This presentation will examine OSM at California University of Pennsylvania (CalU) by describing the author’s integration into classes. He will also highlight local and international work and discuss using this technology to push GIS Service into the classroom.  CalU hold mapathons within classes and a collaborative mapathon with West Virginia University.  Finally, there will be a discussion on the best practices of incorporating OSM into courses.  

Mapping History in the Pacific Northwest

Speaker: Nathan (Nat) Proudfoot

In this talk, I plan to talk about mapping history on Open Historical Map where I have been working on mapping time within the northwest. I would also like to go over how to map with enough time. I would showcase some of the work that has been being done the Seattle area with the results from a 1936 data set and more details from today.

OpenStreetMap Standard Layer: Who's using it?

Speaker: Paul Norman

Mappers see the OpenStreetMap Standard layer every time they view OpenStreetMap.org, but who else is using the layer? With usage logs, who is accessing what is broken down for this important OpenStreetMap service. This talk covers the goals of the service, it’s history, how it's designed, and dives deep into how it's used. Using improved logging functionality, we’ll get answers to these questions specific to the US.

Teen Maptivists

Speakers: Celeste Reynolds & Greg Hill

MapMeetup, an Open Source Community Organizing Tool

Speaker: Scott Anecito

In this talk we quickly cover what federation is, the purpose of the Mobilizon platform that MapMeetup is based on, and features like the platform using OSM's Nominatim as a provider

5:00 - 5:45 pm ET
Maine: State of the State

Speaker: Alex Hennings

An update on recent history, current status, active mappers and work in progress in the great state of Maine. There will be a focus on mistakes, lessons learned, and hopes and dreams.

The YouthMappers Network: Broad and Narrow Perspective

Speakers: Dara Carney-Nedelman & Sophia Rapp

YouthMappers is an international network of 264 university-student-led chapters in 58 countries. We organize, collaborate, and implement mapping activities that respond to actual development needs around the globe - creating and using geospatial data and information that is made publicly available through open platforms.  This presentation will be an overview of the YouthMappers network with a direct example of chapter activities from Clemson Mappers President.

How Could OSM Data Help City Agencies Manage Their Curb?

Speaker: Daniela Waltersdorfer

We always think of the curb as just the minute space that separates a road to a sidewalk, but what really is the curb? My talk will go over how the curb that barely anyone paid attention to (other than parking meters), to a prime real estate area with a myriad of uses and assets. So, what actually makes up the curb? How could OSM data help agencies manage? Ever thought about how the signs and trees we map on OSM could help out a city enforce loading zones? What about double parking on bike lanes? I would like to share my theories, research, share some samples, and have an open discussion.|-

What is new on OSMCha?

Speaker: Wille Marcel

The last months have been very active on the OSMCha development. This talk will show some main new features and what we have in mind for the future of OSMCha.

YouthMappers Validation Hub

Speakers: Katherine O'Byrne & Noelle Dwyer

Since 2014 YouthMappers has been teaching university aged students about OSM and generating lots of data. In 2019 YouthMappers formed the Validation Hub to address potential data issues with YouthMappers projects, provide leadership and training to the YouthMappers network and deepen our commitment to the OSM community by being conscientious stewards of the data we produce.  This talk will focus on the origins, work completed to-date and the path ahead for the YouthMappers Validation Hub.

Mapping Campus Bike Infrastructure with Students

Speaker: Innisfree McKinnon

Working with the campus sustainability office, I have been working on mapping campus bike and transportation infrastructure with university students using OSM. UW-Stout is a small university campus without a campus GIS database, so OSM provides a user-friendly way to map sustainability infrastructure. In this talk I discuss my first attempts to teach novice students how to use OSM to document biking, transportation, and other sustainability related infrastructure on campus.
