This dataset represents freshwater streams on the Chugach National Forest, Alaska. Streams were digitized from 1:31,380 orthophoto quads. Estuarine channel types may extend beyond shoreline. Selected stream arcs on Cordova Ranger District updated October and November 2002. Presence of fish species and stream class were updated.
Existing timber type mylars were developed by the Alaska Regional Office in 1978 using 1:15,840 aerial photography flown in the 1950's-1970's, and digitized primarily under contract. The North Slope Borough digitized the Big Islands and Gravina Management Areas. Other full quads were done primarily by the Brodie Group. The remaining quads were done by the Chugach NF staff using LIDES or ARC/INFO. Additional mapping was done by Bob Green for the BLM Window and Whittier. Warren Oja did mapping for Cooper Landing. The forty quads under contract were as follows: Anchorage A1-A4, Bering Glacier A8 & B8, Cordova A1-A2, Cordova B1-B5, Cordova C3-C4, Middleton Island D1/2, Seward A3-A4, Seward B2-B8, Seward C1-C8, Seward...
This dataset represents wetlands on the Chugach National Forest, Alaska. The underlying data were received from US Fish and Wildlife Service. Wetlands interpreted stereoscopically and transferred to USGS base maps at 1:63,360 scale. Field verification/ground truthing in 8/79, 6/84, 8/85, 8/87, 6/88, 8/90. Total ground truthing time for the Chugach was 5 weeks. Coverage for the Chugach is only about 95% complete. There are no plans at this time to map these areas.
An ASD FieldSpec 4 Hi-Res NG Spectroradiometer was used to collect the reflectance properties of soil and rock in southcentral Alaska, USA (Figure 1) around the city of Anchorage (Figure 2) and the Prince William Sound (Figure 3). Reflectance is a property of the material being observed, being the ratio of the amount of light leaving a target to the amount of light striking the target. Reflectance is a unitless value from 0 to 1, where a value of 0 indicates that the material absorbs all energy and 1 indicates total reflectance. Additionally, samples were collected from the field and later measured using the spectrometer in the laboratory. Both field and laboratory data were collected in the summer and fall of 2022....
