TwitterForest Ecosystem Dynamics (FED) Project Spatial Data Archive: Elevation Contours for the Northern Experimental Forest
The Biospheric Sciences Branch (formerly Earth Resources Branch) within the Laboratory for Terrestrial Physics at NASA's Goddard Space Flight Center and associated University investigators are involved in a research program entitled Forest Ecosystem Dynamics (FED) which is fundamentally concerned with vegetation change of forest ecosystems at local to regional spatial scales (100 to 10,000 meters) and temporal scales ranging from monthly to decadal periods (10 to 100 years). The nature and extent of the impacts of these changes, as well as the feedbacks to global climate, may be addressed through modeling the interactions of the vegetation, soil, and energy components of the boreal ecosystem.
The Howland Forest research site lies within the Northern Experimental Forest of International Paper. The natural stands in this boreal-northern hardwood transitional forest consist of spruce-hemlock-fir, aspen-birch, and hemlock-hardwood mixtures. The topography of the region varies from flat to gently rolling, with a maximum elevation change of less than 68 m within 10 km. Due to the region's glacial history, soil drainage classes within a small area may vary widely, from well drained to poorly drained. Consequently, an elaborate patchwork of forest communities has developed, supporting exceptional local species diversity.
This data layer contains elevation contours for the 10 X 10 km area located within the Northern Experimental Forest. Contours and elevation benchmarks from the United States Geological Survey 7.5" Maine quadsheets for Howland and Lagrange were digitized, and elevation data in feet were added.
The data was revised by projecting it into NAD83 datum by L. Prihodko at NASA Goddard Space Flight Center. Although the data was received at GSFC with an undeclared datum, it was assumed to be in North American Datum of 1927 (NAD27) because the original map from which the data were digitized was in NAD27. Also, the data fit exactly within the bounds of the FED site grid (even Universal Transverse Mercator projections) in NAD27. After projecting the data into NAD83 it was checked to insure that the change was a linear translation of the coordinates.

Howland DEM is a digital elevation model of the 10km X 10km area located within the Northern Experimental Forest. The contours and elevation benchmarks from the United States Geological Survey 7.5'quadsheets for Howland and Lagrange were digitized and then rasterized into a 10m X 10m grid.

Also, the data fit exactly within the bounds of the FED site grid (even Universal Transverse Mercator projections) in NAD27. After projecting the data into NAD83 it was checked to insure that the change was a linear translation of the coordinates only and that the gridded values did not undergo any changes.

TwitterThe main contents of the map include rock (ore) core recovery rate, horizon and thickness of rock or ore body, description of rock (ore) core characteristics (including material composition, structure and structure of rock and ore, contact relationship of rock or ore layer and dip angle of bedding plane, etc.), sampling and testing, etc. After the completion of drilling construction, according to the lithologic distribution of geological logging, combined with the results of sample analysis, according to REO ≥ 1%, Mo ≥ 0.03%, the rare earth ore bed and molybdenum ore bed are re divided by comprehensive research, which is completed by using MAPGIS software. The map reflects the information of borehole lithology and mineralization in the form of graphics, which is the main basis for compiling comprehensive maps and delineating rare earth ore bodies.

TwitterThis map is a mineralization element map of the southern mining area of Geji Town in the western section of the Gangdise Mountains on the Qinghai Tibet Plateau, drawn on a scale of 1:250000. The drawing software includes MAPGIS and CorelDRAW. This map system reveals the regional ore controlling elements and the geological background of mineralization. The map is clearly divided into lithological units through multi-color blocks, where yellow green and light green bases represent surrounding rock strata such as sandstone and granite, and red block areas are marked with mineralized bodies and ore controlling structures, visually presenting the contact relationship between veins and surrounding rock. The mineral types are mainly copper and gold mineralization points, with a small amount of iron, lead, zinc and other mineral points. The spatial distribution of mineral deposits (points) is controlled by faults and fold structures, indicating the key role of tectonic activity in mineralization. This map integrates geological, structural, and mineral information, providing important basis for regional prospecting and exploration, indicating that the southern mining area of Geji Town has significant potential for copper and gold polymetallic mineralization. Subsequent research can focus on the mechanism of structural magmatic coupling controlling mineralization. There is no elevation point or other information in the figure.

TwitterBased on the collection of GPS and stress data of the Qinghai Tibet Plateau, this paper combs the movement rate and stress deformation system of the Qinghai Tibet Plateau, displays the direction and size of each point through MAPGIS software, and then superimposes it on several main tectonic units of Songpan Ganzi flysch belt, North Qiangtang Changdu Simao plate, South Qiangtang Baoshan block and Gangdise Lhasa block. This paper tries to reflect the similarities and differences of the specific deformation modes of each block under the overall stress of the Qinghai Tibet Plateau, and further define the specific deformation style and deformation state of each local area. This is of great significance for a deep understanding of the Cenozoic deformation model of the Qinghai Tibet Plateau, as well as for guiding local disaster prevention and relief and engineering construction.
