CDM-ArcView Manual Views

National Parks 2m View

This is a view of the US National Parks, with NPS shields locating all parks, and white borders surrounding the larger parks. Point park locations are from ArcUSA, while park boundaries are from ArcUSA and NPS combined sources. At this regional scale, a physiographic background appears as a gray hillshade, along with ArcUSA rivers from the 1:25 million scale version. Physiographic data is from the USGS Digital Elevation Model. The other detailed layers, although active, do not appear at this scale.

National Parks Closeup View

This is a view of the Yellowstone area with the detailed rivers, roads and USGS 24k quad sheets showing. All detailed data are from the ArcUSA 1:2 million datasets.

National Parks Biomes View

This is a view of the Pacific northwest parks showing vegetation biomes against physiography. Biome data are from ArcAtlas and comprise a global vegetation classification of about 750 types developed by the Russian Academy of Sciences. The naming convention includes a list of major species, as seen in the 3 example names shown above.

Assateague Park View

This is a view of Assateague Island National Park vegetation data. Assateague is the first prototype park in the National Biological Service/National Park Service vegetation mapping program. This view shows plant communities delineated by the ESRI team during the ecological mapping process with the color infrared aerial photography as a backdrop. Data sources used to determine the plant communities include the color IR aerial photos, field reconnaissance plots, and quantitative field plots, all with locations shown in their respective layers. Plot photographs taken by the ESRI team can also be displayed for any plot or any community, as shown above.

Sequoiah Park View

This is a view of the Sequoiah-Kings Canyon area with data from California conservation agencies. The solid backdrop is the Jepson bioregions for the state. The detailed polygons are from the Calif. GAP Analysis dataset from the US GAP Program. Circular data are endangered species locations randomly buffered to protect their security while still signifying areas of threat. Roads and Place names data come from the park itself.

US Geology 2m View

This is a view of US Geologic types taken from ArcAtlas, with colors randomly assigned by ArcView. The complete global geological classification used and mapped includes about 300 rock types, but the view here shows only the 45 major geological systems.

US Geology Closeup View

This is a view of US Geologic types from ArcAtlas, here symbolized as transparent shades to show the underlying physiographic patterns in relation to geology. In this scheme, precambrian rocks are shaded black, blue/purple indicate paleozoic, greens signify mesozoic, and yellow/red show cenozoic. The parks shown in this area are from the southwest region from Canyonlands at lower left to Rocky Mountain at upper right.

US Wildlife 2m View

This is a view of wildlife data from ArcAtlas, here showing only the range of Pronghorn antelope. About 100 indicator species from all kingdoms are included in this global database, stored as a single coverage using the Arc regions model. As a single coverage, it can show a single speciesí range, or a combined range for any combination of species. It also allows a species list for any delineated area to be produced instantly.

US Wildlife Closeup View

This is a view of the pacific northwest region showing Pronghorn antelope range superimposed against physiography and parks, indicating a general preference for plains in this part of its range.

California 2m View

This is a view of California showing county boundaries in yellow and the Jepson Bioregions for the state, used as the basis for locating the CNPS (California Native Plant Society) vegetation series for the state. The US Forest Service will be applying the CNPS classification to itís ECOMAP polygons, resulting in improved state vegetation maps in the coming year.

California Closeup View

This is a view of northern California showing parks for the area against a backdrop of Jepson bioregions, country boundaries and physiography.

California Specimens View

This is a view of Modoc county in the northeast corner of California, with place names, roads, rivers and federal lands from the California Natural Diversity Database against the Jepson bioregions and physiography. The large yellow dots signify points where botanical specimens were collected, from data at the herbarium of the California Academy of Sciences.

Sinkyone Closeup View

This is a view of the Sinkyone wilderness area in northern coastal California, showing roadless area buffers and stream buffers used to identify critical core wilderness areas in this reserve. These data and analysis are from the Sinkyone Project, a non-profit conservation group active in this region.

Trinity Specimens View

This is a view of Trinity County in northwestern California, showing detailed place name data from the US Geological Survey, Township and Range grids from Californiaís Teale Data Center, and elevation and contour data from ESRIís Digital Chart of the World. The table at the top shows a location description typical of specimen data. The lat-lon data shown in the table is created by a CDM function which allows pointing on the map according to a location description from which it generates the unprojected lat-lon point and posts it to the table.

Global Biomes View

This is a view of North America showing Holdridge Life zones from the World Conservation Monitoring Centre in Cambridge, England. National and subnational boundaries from ESRIís ArcWorld and ArcWorld supplement are shown. The black dots are global specimen points for fire ant (Polystichoetes) collections over the last century, from the Invertebrates collection at the California Academy of Sciences.

Nantucket 2m View

This is a view of the Massachusetts region with basemap data from the ArcUSA database, to show the setting for Nantucket Island and land use patterns analyzed by The Nature Conservancy.

Nantucket Island View

This is a view of Nantucket Island showing land use and sensitive species data from The Nature Conservancy. Candidate reserve areas were created by the ESRI Conservation Program and are shown in white, with Roadless areas drawn from unroaded land left over after buffering around local roads, and land use candidates drawn from buffers around different categories of wild land.

Nantucket Closeup View

This is a view of Nantucket Island showing land use within areas of special concern. Land use polygons were indexed according to a new fragmentation integrity analysis developed by the ESRI Conservation Program, where lowest scores appeared for large, single, rounded areas like ponds and bogs as shown in the green area at right center, and highest scores appeared for fragmented, linear areas like the riparian communities shown at center.

Nantucket Shape Analysis View

This is a view of Nantucket Island vegetation types showing the results of a shape integrity analysis developed by ESRI. This analysis produces an index which gets closer to 1 as all polygons in the class approach the ideal of a single large circular polygon. The more a class is broken into smaller separate polygons or is linear or crenulated in shape, the closer this index will be to 0. Red indicates the lowest value, and it is readily apparent that the red classes are very fragmented in the northeast part of the island, as well as very linear along the islandís beaches. Yellow is the highest score, and in this case included agricultural fields and ponds which tended to form contiguous single blocks of relatively simple shape.
