The Aqueduct 4.0 Global Water Risk dataset from the World Resources Institute (WRI) is now available in ArcGIS Living Atlas of the World. Aqueduct 4.0 translates complex hydrological model outputs from PCR-GLOBWB 2 into intuitive water risk indicators at HydroSHEDS v1 level 6, with aggregations at provincial, state, and national levels. This comprehensive framework assesses both current conditions and future projections of water resources to inform decision-making. For more information about this dataset and how to map it within ArcGIS, visit the full blog by @EmilyMeriam1 and @GonzaloEspinoza-Davalos here.  ... View more

How the next Census could reshape the Congressional Landscape Every decade, the U.S. Census provides updated population counts that directly impact the allocation of political representation. Following the 2030 Census, the fixed total of 435 seats in the U.S. House of Representatives will be redistributed among the 50 states through a process known as apportionment.  Over the last 20 years, Esri has leveraged its Esri Updated Demographics population estimates to forecast congressional seat allocations in anticipation of the decennial U.S. Census. To learn more about Esri Demographics' projections and how they coincide with the upcoming Census, visit this blog by Esri's Chief Demographer @KyleRCassal, @JimHerries, and @AlexHenesy.  ...

The CHELSA bioclimate projections in the Living Atlas have been incredibly popular with the GIS community, and now we have enhanced the collection to include Growing Degree Days above 10 °C, Net Primary Productivity, Snow Cover Days, and Snow Water Equivalent. The new layers provide crucial insights into the future impact of climate change on ecosystems and human wellbeing. The new layers include projections for the early, mid, and late 21st century under several greenhouse gas scenarios (SSPs). As we continue to expand and refine our data collection, we invite everyone to leverage this resource for their work in climate science and environmental management. To learn more about accessing the layer and to see change over time examples, check out this blog by @EmilyMeriam1 and Raf Antwerpen.  ... View more

Did you know that Living Atlas Elevation Layers are updated quarterly with high-resolution elevation data from federal agencies, open sources, and the Community Maps Program? These updates are used within the Terrain, TopoBathy, and Basemap items, which improve your maps and visualizations of elevation across ArcGIS. To see some of the newest lidar-derived updates for this release, check out this blog  by @RajinderNagi. ... View more

The National Land Cover Database (NLCD) has long been the standard for land cover mapping in the United States. This year, the USGS announced a major advancement in land cover mapping with the release of the Annual NLCD products. Harnessing the full Landsat data record, Annual NLCD provides a scientific suite of land cover data from 1985 to present. The data products are the result of a confluence of methodologies from past land cover projects together with modern innovations in geospatial deep learning technologies to create the next generation of land cover and land change information. Esri and the ArcGIS Living Atlas team are providing accessibility to this data in the form of a ready-to-use imagery layer and a web mapping application, the NLCD Land Cover Explorer. Change analysis is essential to deriving information from a land cover time series. One of the foremost capabilities of this app is dynamic change analysis, providing dynamic visual and statistical change across annual slices of the NLCD Land Cover data archive.

Have you ever needed to perform a local water quality assessment? Getting started with that process is now made easier by having the EPA Impaired Water Bodies dataset available in ArcGIS Living Atlas of the World. Under Section 303(d) of the Clean Water Act, states and Tribes are required to assess and report water bodies that do not meet water quality standards. These hydrologic features are classified as impaired if they are affected by pollutants or conditions that limit their designated uses—such as drinking water supply, fish consumption, recreation, and more. Each state or Tribe submits its assessments to the U.S. Environmental Protection Agency (EPA), and in many cases, they also develop restoration plans that include Total Maximum Daily Loads (TMDLs)—the maximum amount of a pollutant that a water body can receive while still meeting standards.

ProtectedSeas, a pioneering project committed to mapping and sharing global ocean protection data, is now part of ArcGIS Living Atlas. By providing detailed, standardized, and up-to-date information on marine protected areas and their regulations, ProtectedSeas empowers decision-makers, researchers, coastal communities, and advocates worldwide.  ProtectedSeas’ data in the Living Atlas is already making a difference. Researchers are leveraging these layers to identify gaps in protection, assess compliance with international agreements, and track conservation outcomes. Coastal planners and local governments use the data to align development with ecological priorities. Educators bring the ocean to life in classrooms, and NGOs use the maps to engage the public and advocate for stronger protections. For more information about the ProtectedSeas and their new Living Atlas layer, check out this blog by @KeithVanGraafeiland.  ... View more

Understanding how temperature and precipitation may change in the future is a key part of the Steps to Resilience and building more climate-smart communities. We are excited that NOAA has contributed the latest climate projections, LOCA2, to the Living Atlas that were developed for the 5th National Climate Assessment (NCA5). Which climate data should you use? This blog helps address when to use LOCA2, CHELSA, NCA5 Atlas, or Global Wet Bulb Temperature in your work.  For the full blog by @DanPisut and @rantwerpen, click here.  ... View more

Understanding where and how fatal motor vehicle crashes occur is crucial to making roads safer, informing public policy, and supporting transportation planning. A new feature layer sourced from the National Highway Traffic Safety Administration (NHTSA)’s Fatality Analysis Reporting System (FARS) is now available in ArcGIS Living Atlas of the World, providing data on motor vehicle fatal crashes from 2019 through 2023, across the United States. The FARS Fatal Motor Vehicle Crashes 2019 to 2023 layer, along with several web maps and an accompanying dashboard are all available in Living Atlas to help support the GIS community in advancing transportation safety toward the goal of zero motor vehicle deaths. This goal, shared by Vision Zero and the U.S. Department of Transportation’s Federal Highway Administration’s Safe System Approach, acknowledges that while reaching zero deaths may be an ambitious goal, no loss of life on our roads is acceptable—and it is a collective effort to systematically eliminate traffic fatalities and serious injuries. For more information about FARS and to learn how to use and access the content from Living Atlas, read the full blog by Steven Aviles here.  ... View more
