Using StoryMaps to Celebrate Arlington County’s 1920 Centennial

Up until the end of the American Civil War, both present-day Arlington County and Alexandria County were included under the Alexandria County name. Then, in 1870, Virginia's re-written Constitution called for the state’s many incorporated cities to become independent from their respective counties. Thus, Alexandria City separated from the County of Alexandria, which was renamed to “Arlington County” to avoid confusion.

Blue Raster partnered with the Arlington Historical Society to create a StoryMap celebrating Arlington County's centennial anniversary. This StoryMap highlights 115 points of historical significance throughout the county, as curated by the Arlington Historical Society. The map displays a diverse range of feature types, including bridges, farmhouses, mansions, schools, and more. Each location also features a high-quality picture, modern-day address, and informative site description.

This StoryMap also features a custom basemap, created from scratch by Blue Raster’s GIS and design teams. This basemap gives viewers a better view of what Arlington County looked like in 1920, including historic street and community names. In addition to a view of the past, this basemap also contains elements of the present. Zooming in activates a layer showing current-day building footprints that can help the viewer relate present locations to historical points of interest.

Since our inception in 2002, Blue Raster has been headquartered in Arlington County, Virginia. We always love working with local businesses and organizations, and we look forward to celebrating the county’s centennial anniversary with this StoryMap.

TNC Story Map: Planting Healthy Air

By 2050, the majority of humanity will live in cities, towns, and other urban areas. Among the most pressing of global urban environmental challenges is air quality. In cities, the most damaging air pollutant is particulate matter (PM), but another pressing problem cities face is heat: the air is simply so hot in summer that human health is impacted. At the same time, with climate change, increasing temperatures around the world are exacerbating excess heat produced by cities and causing dangerous heat waves.

To address this concern for the future, The Nature Conservancy (TNC) investigated the effect of planting trees in urban areas. The science is clear that tree leaves play a part in removing particulate matter from the atmosphere along with many other air pollutants. Also, the shade provided by urban trees along with the transpiration of water during photosynthesis can help reduce air temperatures, while also reducing electricity needed for residential cooling. From an economic perspective, TNC found planting trees produces a significant return on investment when planted strategically in certain areas of a city.

17_trees_remove_pollution_1To determine precisely where and how much trees can help, The Nature Conservancy collected geospatial information on forest and land cover, PM2.5 pollutant concentration, and population density for 245 cities and used relationships established in the literature to estimate the scope of current and future street trees needed to make urban air healthier. The resultant report, titled “Planting Healthy Air,” advises cities on where trees offer the highest return on investment for improving public health by addressing particulate matter and excess heat.

To help visualize this data and share this story, TNC came to Blue Raster for help creating an interactive story map built on the latest Esri technology. The Planting Healthy Air story map details the project’s motivation, visualizes its geographic data and geospatial analysis, and describes a simple plan for cities to reduce pollution and temperature by planting trees. The viewer can select a section of interest or scroll through all of them, exploring and interacting with maps. Viewers can see neighborhood-level analysis in any of the 245 cities included in the report or read in-depth remarks about one of 15 focus cities.

Built on ArcGIS Online, the Planting Healthy Air story map uses Cascade, a new template designed for immersive storytelling. The story map’s interactive format allows viewers to explore the data and analysis on their own terms and get personalized information about the places that matter to them.

“Thanks to Blue Raster for all their hard work. We’re really excited about this new resource for sharing our science!”
