"Native Land Digital is a Canadian not-for-profit organization, incorporated in December 2018. Native Land Digital is Indigenous-led, with an Indigenous Executive Director and Board of Directors who oversee and direct the organization. [...] Maps potentially function as colonial artifacts and represent a very particular way of seeing the world – a way primarily concerned with ownership, exclusivity, and power relations."

"An idea in 2007 to make geographic data easily accessible and understandable to policy makers grew into what is now PolicyMap: a data warehouse of over 50,000 indicators accessible through a state-of-the-art mapping and analytics platform."

"This information has been meticulously sourced from the three largest, most comprehensive and impartial crowdsourced databases on police killings in the country: FatalEncounters.org, the U.S. Police Shootings Database and KilledbyPolice.net. We've also done extensive original research to further improve the quality and completeness of the data; searching social media, obituaries, criminal records databases, police reports and other sources to identify the race of 90 percent of all victims in the database." Provides map and infographics as well as raw data download as spreadsheet.

"Redlining directed both public and private capital to native-born white families and away from African American and immigrant families. As homeownership was arguably the most significant means of intergenerational wealth building in the United States in the twentieth century, these redlining practices from eight decades ago had long-term effects in creating wealth inequalities that we still see today. Mapping Inequality, we hope, will allow and encourage you to grapple with this history of government policies contributing to inequality." The data are available as shapefiles and GeoJSON, and are searchable by description, transcription, city, and state.

"D4BL has worked to consolidate state level data to explore the disproportionate impact of COVID-19 on Black people in the US. The D4BL COVID-19 Dataset captures state-level COVID-19 cases and deaths for Black people in the United States. D4BL established a team of volunteer data scientists to develop a codebase for automating the data extraction from state websites and storing it into this dataset."

"A group of Inuit experts, community researchers, and university researchers, have worked together over the past several years to document specialized Inuit knowledge about sea ice. Inuit elders and hunters are the local experts on sea ice. Through long term observation and experience with the sea ice, they have developed deep and rich understandings of the marine environment"
