This book had its seeds in 2011, when I found myself at Esri’s annual User Conference in San Diego, California. There, with 15,000 self-proclaimed map geeks, I was astonished to discover a whole community of people who understood the power of visuals to create understanding and trust—and to solve the world’s pressing problems.

Information on the amount of water flowing in streams and rivers is critical to the management of water resources, emergency response to flooding, fisheries management, and many other uses. This layer provides access to real-time stream gauge readings compiled from a variety of agencies and organizations.Dataset SummaryThe Live Stream Gauges layer contains real-time measurements of water depth from multiple reporting agencies recording at sensors across the world. This layer uses GeoEvent Processor to ingest and consolidate the many live sensor feeds, and updates itself every hour. At some gauges, flow in cubic feet per second is estimated using a stage-discharge rating curve. Flow forecasts are also provided where available. These sensor feeds are owned and maintained by the GIS community. For details on the coverage in this map and the users who contributed data for this map via the Community Maps Program, view the list of Contributors for the Live Stream Gauges Service. If you want to contribute your organization's gauges, read more about the program here.

Safe, secure, and abundant bicycle parking is necessary to support the District’s growing number of people using bikes for transportation, commuting, and recreation. Providing sufficient bicycle parking is part of DDOT's strategy to promote bicycling in the District of Columbia and reduces the number of bikes locked to trees, benches, and railings.

When rain falls over land, a portion of it runs off into stream channels and storm water systems while the remainder infiltrates into the soil or returns to the atmosphere directly through evaporation. Physical properties of soil affect the rate that water is absorbed and the amount of runoff produced by a storm. Hydrologic soil group provides an index of the rate that water infiltrates a soil and is an input to rainfall-runoff models that are used to predict potential stream flow. For more information on using hydrologic soil group in hydrologic modeling see the publication Urban Hydrology for Small Watersheds (Natural Resources Conservation Service, United States Department of Agriculture, Technical Release–55).

This layer is derived from the 30m rasters produced by the Natural Resources Conservation Service (NRCS). The value for hydrologic group is derived from the gSSURGO map unit aggregated attribute table field Hydrologic Group - Dominant Conditions(hydgrpdcd). The seven classes of hydrologic soil group followed by definitions:Group A - Group A soils consist of deep, well drained sands or gravelly sands with high infiltration and low runoff rates.Group B - Group B soils consist of deep well drained soils with a moderately fine to moderately coarse texture and a moderate rate of infiltration and runoff.Group C - Group C consists of soils with a layer that impedes the downward movement of water or fine textured soils and a slow rate of infiltration.Group D - Group D consists of soils with a very slow infiltration rate and high runoff potential. This group is composed of clays that have a high shrink-swell potential, soils with a high water table, soils that have a clay pan or clay layer at or near the surface, and soils that are shallow over nearly impervious material.Group A/D - Group A/D soils naturally have a very slow infiltration rate due to a high water table but will have high infiltration and low runoff rates if drained.Group B/D - Group B/D soils naturally have a very slow infiltration rate due to a high water table but will have a moderate rate of infiltration and runoff if drained.Group C/D - Group C/D soils naturally have a very slow infiltration rate due to a high water table but will have a slow rate of infiltration if drained.

This Dashboard presents results from Hoffman et al. (2020) which showed that formerly "redlined" neighborhoods are predominantly warmer today than their non-redlined neighbors in 94% of the cities studied. This relationship is accompanied by a similar, although opposite, trend in tree canopy, whereby redlined neighborhoods have systematically less tree canopy today - and more impervious, hard surfaces - than their non-redlined neighbors. Finally, we have included estimates of the neighborhood demographics - indicated by its % non-white population and median house value - to show that, as many studies have shown previously, that these formerly redlined areas remain relatively lower-resourced and primarily communities of color, underscoring the need to address climate change equitably in these cities which were redlined in the 1930s and 1940s.The web map for this Dashboard can be accessed here.

The cities included in the app are - Chelsea, Everett, Lynn, Malden, Peabody, Quincy, Revere and Salem.The Improvement Ratio is an interesting way to look at a city as it immediately reveals land parcels that are under-utilized. It is calculated as a ratio between value of all improvements built upon a land parcel to the value of the land contained within the parcel boundaries. Data Source: DataCommon, MAPC Boston

The segregation of public schools was a common practice throughout many decades of U.S. history. During the Reconstruction period after the Civil War, Congress passed three constitutional amendments to protect newly-freed Black Americans. While racial segregation was forbidden in some regions, in other areas, namely the southern states, racial segregation was enforced by law. The transition to a more diverse and inclusive public education system was fueled by families, activists, and the NAACP who used litigation to make sure that all students were afforded access to an equitable education. On May 17, 1954, the Supreme Court of the United States ruled segregation in public schools was unconstitutional in Brown v. Board of Education. The ruling was a pivotal point students, educators, and the ongoing fight for civil rights.

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Trust Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats may be excluded because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition.The U.S. Fish and Wildlife Service (Service) is the principal Federal agency that provides information to the public on the extent and status of the Nation's wetlands. The Service's strategic plan for our vast national wetland data holdings is focused on the development, updating, and dissemination of wetlands data and information to Service resource managers and the public.For more information visit: https://www.fws.gov/wetlands/index.htmlView Wetlands Data on the Wetlands Mapper at: https://www.fws.gov/wetlands/Data/Mapper.htmlWetlands Web Services are available at: https://www.fws.gov/wetlands/Data/Web-Map-Services.htmlWetlands Data available as a KML at: https://www.fws.gov/wetlands/Data/Google-Earth.htmlWetlands Data Downloads available at: https://www.fws.gov/wetlands/Data/Data-Download.htmlWetland Data Standards available at: https://www.fws.gov/wetlands/Data/Data-Standards.html

The NOAA Climate Prediction Center generates monthly to seasonal forecasts of the probability of temperature and precipitation being greater or less than "normal" (the historical average). These layers show the probability of whether temperatures in the United States will be above or below normal over the next 6-10 days, 8-14 days, 30 days, and 90 days ("season"). TemperatureThe color palette uses orange to blue to represent higher or lower than average temperature probability. Dark orange colors imply a greater probability that temperatures will be higher than normal - but the color implies nothing about the actual amount. In other words, dark orange does not mean that these areas will receive higher temperatures than light orange areas, just a greater chance that the areas will be warmer than normal.The National Weather Service maintains a variety of ArcGIS services via their CloudGIS system. The REST endpoints for all of these services can be found here: https://www.weather.gov/gis/cloudgiswebservices

Water Filter DistributionBrain Trust for Tropical Disease Research and Prevention is beginning to facilitate the distribution of water filters and outreach information about safe drinking water to Puerto Rico’s communities post Hurricane Maria. The filters will be distributed home to home in collaboration with the Federally Qualified Health Centers and the Department of Health. At each home visit a team will teach about filter assembly, use and maintenance, provide educational outreach materials and conduct a brief survey about the community, the household, their access to potable water and general health information.We would like to provide your home with one filter that will provide water for six family members for approximately six months. It is recommended that the filter’s cartridge be cleaned by rubbing it gently with white sugar or other non-toxic abrasive material. If water no longer drains out of the filter system, after cleaning, the filter should be replaced. A replacement cartridge can be obtained at the Utuado Community Health Center or purchased at your local hardware store.Collaborators:PRiA, PRDOH, Federally Qualified Community Health Centers, Utuado Community Health Center, Brain Trust for Tropical Disease Research and Prevention, and the Puerto Rico Science, Technology and Research Trust.

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.

Important Note: This item is in mature support as of June 2023 and will retire in December 2025. A new version of this item is available for your use.The layers going from 1:1 to 1:1.5M present the 2010 Census Urbanized Areas (UA) and Urban Clusters (UC). A UA consists of contiguous, densely settled census block groups (BGs) and census blocks that meet minimum population density requirements (1000 people per square mile (ppsm) / 500 ppsm), along with adjacent densely settled census blocks that together encompass a population of at least 50,000 people. A UC consists of contiguous, densely settled census BGs and census blocks that meet minimum population density requirements, along with adjacent densely settled census blocks that together encompass a population of at least 2,500 people, but fewer than 50,000 people. The dataset covers the 50 States plus the District of Columbia within United States. The layer going over 1:1.5M presents the urban areas in the United States derived from the urban areas layer of the Digital Chart of the World (DCW). It provides information about the locations, names, and populations of urbanized areas for conducting geographic analysis on national and large regional scales. To download the data for this layer as a layer package for use in ArcGIS desktop applications, refer to USA Census Urban Areas.

Summary:The Fire Event Data Suite, or FEDS, algorithm uses high resolution VIIRS observations to map fire perimeters, identify the active portion of fire fronts, and track the progression and attributes of individual fires every 12 hours. For individual fire events, FEDS contains information on the latest active fire detections, as well as the total fire event history in 12 hour increments. The vector output from the FEDS algorithm is produced within approximately 4 hours following the availability of VIIRS 375 m active fire data in FIRMS. The FEDS algorithm was originally developed and tested for large fires in California (Chen et al., (2022)). The EIS Fire team has scaled the production of the fire event tracking approach to cover CONUS and Canada, with data available via OGC API. Data for additional regions, including Alaska and Hawaii, will be released through FIRMS when available.Information on this data and FIRMS can be found here.Suggested Usage:Perimeter data are helpful for understanding the time series progression of a fire event, as observed via the VIIRS sensor. Given the source data, the same considerations that must be taken for FIRMS active fire data are applicable here. All data are experimental and should always be verified with supplementary sources of information when available.The VIIRS Modeled Fire Perimeter Data product provides situational awareness for large fire events in CONUS and Canada every 12 hours, based on the FEDS algorithm and available 375 m VIIRS active fire detection data from Suomi-NPP and NOAA-20. The modeled perimeter is an estimate of the fire-affected area, active portion of the fire perimeter, and metrics of fire behavior. The VIIRS Modeled Fire Perimeter data also provides a history of modeled large fire growth every 12 hours for all fire events detected by VIIRS in CONUS and Canada. By contrast, the USA Fire Perimeter layer is the most recent official incident perimeter data. Official incident data provide a more precise estimate of the perimeter of large fire events in the US than the VIIRS Modeled Fire Perimeter data. The USA Fire Perimeter layer is updated periodically with new official incident perimeter data.Date of Next Image:Updates available at approximate 12-hour intervals.Satellite/Sensor:Suomi NPP and NOAA-20 satellites carrying the VIIRS sensor.
