This dataset is not just a collection of footprints; it’s a narrative of the regions it covers, telling stories of urban development, demographic changes, and architectural evolution. The partitioning by admin boundaries in cloud-native formats like PMTiles and GeoParquet enhances its usability, making it a go-to resource for urban developers and demographers.
Taxi Zones from TLC Trip Record Data
This dataset provides a unique perspective on urban transportation, detailing the Taxi Zones of New York City. It’s like having a street-level view of the city’s bustling taxi network, transformed into a format that’s ripe for analysis in urban planning and transportation studies. The inclusion of GeoParquet and PMTiles versions of the original Shapefile exemplifies the adaptability of GeoParquet in various urban datasets.
Overture Open Buildings
Overture’s experimental re-distribution of their buildings dataset in ‘Cloud-Native Geospatial’ formats is a step towards democratizing building data. It’s an initiative that provides detailed building footprints, essentially sketching the urban landscapes in a digital format that’s easily accessible and analyzable. This dataset opens up new avenues for urban studies and planning, offering a fresh perspective on the built environment.
GLanCE: A Global Land Cover Training Dataset
The GLanCE dataset is a chronicle of the Earth’s changing landscapes, spanning from 1984 to 2020. It’s a digital time capsule that contains nearly 2 million training units for land cover classes globally. For those involved in environmental monitoring, land use research, and climate studies, this dataset offers a medium-resolution window into the past, presenting an opportunity to study the evolution of global ecosystems over three and a half decades.
National Surface Depressions
This dataset delineates depressions from 10-m DEMs across the nation, offering a unique perspective on geological formations and environmental features. It’s akin to having a detailed contour map of the nation’s terrain, providing invaluable data for geological and environmental studies.
Detailing the extent of Geographically Isolated Wetlands in the US, this dataset is a vital tool for conservationists and ecologists. It’s like having a digital magnifying glass over the country’s wetland ecosystems, offering a detailed view of these critical habitats.
National Wetlands Inventory
The NWI offers an exhaustive look at US wetlands, providing a comprehensive resource for conservation and ecological research. This dataset is not just a collection of data; it’s a narrative of the country’s wetland ecosystems, their distribution, and characteristics.
Energy Performance Certificate Ratings (Domestic) – England and Wales
This dataset provides a window into the energy efficiency of properties across England and Wales. It’s an essential tool for understanding the environmental impact and energy consumption patterns of domestic properties. The dataset not only offers data on energy efficiency but also includes recommendations for energy-efficient improvements, making it a valuable resource for environmental studies and energy conservation initiatives.
