Mapping Parklands

    In their most basic form, maps show us where things are and how to get there. We pore over wrinkled road maps on summer vacation. We print out Internet directions to the nearest post office or supermarket. At the mall, we check the wall map to save our tired feet from a wrong turn. In our national parks, maps point us to the geyser basin, natural bridge or waterfall we came to experience. Maps and geographic information have always served another, larger purpose in the National Park Service, to preserve America’s most special places for our benefit, enjoyment, and education.
      In the early days, cartographers created hand drawings of parks to illustrate such features as wagon trails, cattle grazing areas, wildfire perimeters, battlefield topography, and stream meanderings. Some of the earliest maps came from John Wesley Powell and his expedition through the Grand Canyon and from the U.S. Army Fifth Cavalry at Yosemite in 1896. Field maps from military cartographers and surveyors have helped national parks recreate authentic landscapes for visitors to see where their ancestors fought and died during the Revolutionary War, War of 1812, and Civil War.
     Today, the park service combines the best of early cartography with the latest technology to collect and display geographic information. Relatively new mapping tools include GIS software, global positioning systems, satellite photography and storage of national park maps on computers for easy access and review. The park service now spends more than $17 million annually on geographic data. It is a grand endeavor of more than 11,000 topographic map sheets representing more than 84 million acres. The park service and other partners together are mapping soils, plant life, geology, and other earth science themes at more than 388 national parks. The ongoing program eventually will produce the first standard set of digital national park base maps.
    Using GPS and hand-held computers in the field, the park service can more accurately pinpoint locations of archeological sites, endangered species, and nesting areas and then download them into GIS maps for review.  A GIS map can show the geographic relationship of bird nest areas to soils, erosion rates, elevation and vegetation in that area. The ability to display all the information layers on a single map helps park managers as they decide where to release captive-bred California condors into the wild, close a trail to protect newborn bighorn sheep, or increase patrols against artifact theft.
     Most mapping and geographic studies now extend beyond national park boundaries. They might display the relationship of the park to streams, coastlines, glaciers, rock formations, hazardous waste cleanup sites, and even cities. The park service works with several federal agencies and other groups to collect geographic information using sophisticated sensors on satellites, aircraft, balloons, ships, and submarines. Displaying the information on GIS maps helps the park service compare different types of data. GIS technology can help park managers predict how various factors, such as drought, shoreline changes, or increased thermal activity, might affect a park. The power of GIS helps us relate, analyze, and model historic and current features and phenomena within a particular study area. Without new technology and geographic information, the National Park Service would face a difficult and sometimes impossible task to measure, map and understand America’s changing landscape and environment.

Tim Connors, Capitol Reef NP's not just for scenery anymore

GIS and cartographic tools are particularly important to the geologists working in national parks. Geology, often scoffed at as merely being attributable only to scenery, actually play a much wider role in the ecosystem. The importance of geology to our everyday activities is obvious to the geologist: it ranges from shaping the earth’s surface to controlling where we eventually settle in communities. With GIS, the geologist can illustrate the importance of the science of geology to others, including soil scientists, botanists, and ecologists, and national park visitors. Capitol Reef National Park in Utah uses GIS maps help predict habitat for threatened and endangered species, including Winkler’s cactus, Barneby reed-mustard, and Jones cycladenia. The park also found a direct link between the presence of several plant species and Navajo sandstone. Geologic maps describe underlying conditions of natural systems and are key in the study of ecosystems, earth history, soils, and environmental hazards such as fires, landslides, and falling rocks. When combined with GIS technology, these maps have advantages over traditional paper geologic maps. GIS maps display the relationship between the earth’s surface and bedrock to data on soil, vegetation, water and other features. It allows study of all these features on a single precise map for fast, easy review and creates a powerful database. The park service has developed many of its digital maps using ArcView software developed by ESRI.

Data Access

Glacier Bay National Park and Preserve connects us to wild Alaska, now and for all time. Its tidewater glaciers, deep fjords, mossy rainforests, rugged coastline, and snow-capped peaks provide a living laboratory to explore the natural world. Its diverse landscapes and seascapes support wildlife ranging from humpback whales, porpoises, and harbor seals, to black bears, wolves, and tufted puffins. A mosaic of plant life blankets the coastal and alpine regions, including alder, spruce, heath, spongy muskeg, and a few species in areas released from the grip of glaciers. These complex ecosystems present park managers with scientific information ranging from detailed undersea profiles to the distribution of bear habitat. The national park at Glacier Bay uses GIS technology to display complex and voluminous information in map-enabled databases for fast and easy access to data, aerial and ground photographs, sound files, and video. These databases provide instant spatial access to tens of thousands of photos, many taken in remote areas that the average park manager may never visit. A manager can zoom in on the map, click on a point, review all the photos taken there, see graphs of scientific data, view a species list specific to that site, even read the notes taken by the field crew at the site. One database stores information about the distribution of whales in Glacier Bay, helping managers decide where and when to restrict sea-going vessels in the summer tourist season. Another database on bear sightings and bear-human interactions helps managers decide when to close remote campsites to protect visitors and their belongings. Another project includes a talking map that helps Native American students learn the traditional names of local places and provides them a crucial link to the cultural landscapes of Glacier Bay. These are just some of the ways the national park uses databases supported by GIS technology.

FMSS and LCS Integration at Kalaupapa NHP

Kalaupapa National Historic Park contains the setting for two tragedies in Hawaiian history. The first was the forced removal of indigenous people in 1865 and 1895 from an area where they had lived for more than 900 years on the island of Molokai. The second was the forced isolation of thousands of Hawaiians sick with leprosy between 1866 and 1969, first at Kalawao and then at Kalaupapa. Many surviving patients of Hansen’s Disease, or leprosy, still live at Kalaupapa. Hundreds of historic buildings remain, and distinct neighborhoods support many activities of daily life. The National Park Service and state of Hawaii have been putting these historic buildings under the park’s care since its creation in 1980. The park reviewed the historic value of each structure and identified more than 200 buildings as a high priority for preservation. ArcView software developed by ESRI displayed the location of each historic building on an interactive GIS map. The map contains data on the condition of each building, and the work and money needed for restoration. The ability to join GIS data to other databases has given managers a new tool to preserve history at Kalaupapa.

Flexible Image Classification With ARCGIS

The 15 national parks of Alaska cover 54 million acres of some of the most pristine lands in America. From glaciers to grasslands and from polar bears to reindeer, these parks feature an incredible variety of, habitat, wildlife, and plant species across vast ecosystems. Mapping the health and analyzing trends in these theses ecosystems has become a job for GIS. At Katmai National Park and Preserve, GIS specialists used ArcGIS software developed by ESRI, satellite images and other technology to map the types of vegetation in a study area of more than 4 million acres of rugged, remote wilderness. As a result of this work, Katmai produced a final, generalized map showing the land cover of the entire park. These GIS-based maps help park managers evaluate the condition of ecosystems and make planning decisions to guide their preservation.

The unique GIS map, “Existing Public Recreational Lands in Alaska and Yukon Territory” shows all the public lands of Alaska on one sheet. The map provides vital information for regional planning in the state’s national parks, based on data collected from state and federal agencies and the Internet. It is one of a series of digital maps distributed to national parks in Alaska that helps scientists and managers use GIS technology in their daily work. Another popular GIS map shows the national parks of Alaska in relation to federally designated “Wild and Scenic Rivers.” The park service also produces GIS maps on paper, including several statewide maps and a series of park maps for many uses, including wilderness and fire management.

Enhanced Wetlands Mapping at Point Reyes National Seashore

Point Reyes National Seashore in northern California offers haven to thousands of migratory birds and more than 50 animal species, including elephant seals, gray whales, and tule elk. Its ocean views, winding trails, and historic lighthouse offer inspiration and recreation. Its rare coastal wetlands feature salt, brackish, and freshwater marshes, meadows, and seasonal ponds. This national park aims to preserve, protect and restore these invaluable wetlands from hazardous material spills, failing septic systems, beef and dairy operations, construction, and from historic neglect and abuse of the land. As a preservation tool, GIS technology helps the National Park Service accurately map the location, size, and type of wetlands as a way to evaluate environmental damage and plan restoration. In one case, field crews identified plant species found in wetlands of the 4,000-acre Abbotts lagoon. The park displayed the botanical inventory on a detailed GIS map for research, planning and public review.
