As a way to celebrate GIS Day and OpenStreetMap, we are encouraging everyone to go online either during this week or on GIS Day and contribute to the OpenStreetMap basemap. You may consider improving the basemap in your own community. Here are several projects to consider:
Public Lab Mongolia – https://tasks.hotosm.org/projects/9560/ Public Lab Mongolia (PLM), a local non-governmental organization in Mongolia, is leading the Mongolian chapter for volunteer mappers through the HOTmicrogrant COVID-19 project, as part of their mission to promote open data and disaster preparedness. This mapping will also help with COVID-19 response efforts. This project is to map Ulaanbaatar capital city of Mongolia, is organized by PLM in collaboration with the Mongolian Geo-spatial Association and local universities.
Hurricane Eta – Nicaragua – https://tasks.hotosm.org/projects/9765 Hurricane Eta brought wind, rain and storm surge to the coast of Nicaragua. This project is to finish the basemap of Bilwi (Puerto Cabezas) by digitizing buildings from MAXAR imagery. Available to beginners, there may be tricky tasks in this project as some areas have been partially mapped with older imagery and vegetation can often hide parts of structures. Make sure to review the instructions for tips on how to overcome these challenges and provide high quality data.
The second part of Earth Observation Day was dedicated to using OpenStreetMap to remotely map Wayland, Iowa and Mindanao region of the Philippines.
Amy Logan, an IowaView staff member, gave a brief introduction to remote sensing and OpenStreetMap. Then mappers began working on a TeachOSM task – Improving the Iowa OSM Basemap: Wayland, Iowa (https://tasks.teachosm.org/project/981). Beverly Conrad, the city clerk of Wayland came for the mapathon and was able to provide local knowledge about the areas participants were mapping. New mappers were encouraged to do the OSM iD Editor Walk-through before they began mapping. It provides users with a nice hands-on introduction of the OpenStreetMap interface and how to create data.
Wayland is a small town (population: 966) in southeast Iowa that has wanted to move towards a GIS asset management system, yet much of their city needed to be mapped. As a result of the volunteer efforts of our 22 mappers during the Earth Observation Day mapathon event, partcipants mapped over 70% of the city, including over 470 buildings as well as sidewalks, alleys, parks, and other points of interest. Below is a before and after screenshot of the OpenStreetMap basemap for the City of Wayland, Iowa.
Thank you, Mappers!
The second project was a Humanitarian OpenStreetMap Task improving the basemap in the Philippines to promote food security. This project added details to the basemap such as minor roads and path, buildings, and farmland.
