Each map covers a minimum area of 0.5 degrees longitude by 0.5 degrees latitude or about 54 kilometres by 54 kilometres. The contour interval is 20 metres. Many maps are supplemented by hill shading. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours, localities and some administrative boundaries. Product Specifications Coverage: Australia is covered by more than 3000 x 1:100 000 scale maps, of which 1600 have been published as printed maps. Unpublished maps are available as compilations. Currency: Ranges from 1961 to 2009. Average 1997. Coordinates: Geographical and either AMG or MGA coordinates. Datum: AGD66, GDA94; AHD Projection: Universal Transverse Mercator UTM. Medium: Printed maps: Paper, flat and folded copies. Compilations: Paper or film, flat copies only.

    The map title is Happy Valley-Goose Bay. Tactile map scale. 2 centimetres = 3 kilometres North arrow pointing to the north. Happy Valley-Goose Bay and surrounding area. Goose Bay is shown with a wavy symbol to indicate water. The Churchill River, shown with a wavy symbol to indicate water, flows left to right into Goose Bay. Main road, Trans Labrador Highway. A circle with the shape of an airplane in it indicates Goose Bay Airport to the west of the city. Tactile maps are designed with Braille, large text, and raised features for visually impaired and low vision users. The Tactile Maps of Canada collection includes: (a) Maps for Education: tactile maps showing the general geography of Canada, including the Tactile Atlas of Canada (maps of the provinces and territories showing political boundaries, lakes, rivers and major cities), and the Thematic Tactile Atlas of Canada (maps showing climatic regions, relief, forest types, physiographic regions, rock types, soil types, and vegetation). (b) Maps for Mobility: to help visually impaired persons navigate spaces and routes in major cities by providing information about streets, buildings and other features of a travel route in the downtown area of a city. (c) Maps for Transportation and Tourism: to assist visually impaired persons in planning travel to new destinations in Canada, showing how to get to a city, and streets in the downtown area.

    Description

    The Franklin Bluffs patterned-ground grids are located in Subzone D, on the coastal plain of the Alaska North Slope, just west of the Sagavanirktok River. There are three 10 x 10 m grids: one near the rim of an abandoned river terrace (dry), one on the same terrace, but further back from the edge and a little lower in elevation (mesic), and one on the lower abandoned river terrace below the first two (wet). All three have a complex of vegetation types created by non-sorted circles, with sparser vegetation in the circles and more continuous vegetation between the circles.

    Description

    The Howe Island biocomplexity grid is located on a 1.5 x 0.5 km island off the delta of the Sagavanirktok River, west of the Endicott Causeway in the Prudhoe Bay oilfield, AK. There is one 10 x 10 m grid, with a complex of vegetation types created by 10 to 30-m polygonal cracking due to permafrost ice-wedges, smaller 1 to 3-m non-sorted circles, and small 10-20 cm surficial desiccation cracking. There is sparse vegetation on the sorted circles and more continuous vegetation between the sorted circles and in the troughs between the polygons.

    Description

    This dataset includes vegetation cover maps, Normalized Difference Vegetation Index (NDVI) maps, snow depth and thaw depth data that were obtained as part of a biocomplexity project on the North Slope of Alaska, USA, and the Northwest Territories (NWT), Canada. In Alaska, seven sites are located along the Dalton Highway and in the Prudhoe Bay Oilfield area, forming a transect across the climate gradient of the North Slope. From South to North, the sites are Happy Valley, Sagwon (an acidic and nonacidic site), Franklin Bluffs, Deadhorse, West Dock and Howe Island. Four sites are in the NWT, forming a latitudinal gradient from South to North; the sites include Inuvik, Green Cabin, Mould Bay, and Isachsen.

    Description

    The Sagwon patterned-ground grids are located at the northern edge of the rolling foothills, at the boundary with the flatter coastal plain. This is also the boundary between Subzones E and D, and between the acidic tundra to the south and the nonacidic tundra to the north. There are three 10 x 10 m grids, one with acidic tussock-sedge, erect dwarf-shrub, moss vegetation (MAT), and two grids in the nonacidic nontussock-sedge, prostrate dwarf-shrub, moss tundra (MNT). The two MNT grids are similar. The Sagwon patterned-ground grids are located at the northern edge of the rolling foothills, at the boundary with the flatter coastal plain. This is also the boundary between Subzones E and D, and between the acidic tundra to the south and the nonacidic tundra to the north. There are three 10 x 10 m grids, one with acidic tussock-sedge, erect dwarf-shrub, moss vegetation (MAT), and two grids in the nonacidic nontussock-sedge, prostrate dwarf-shrub, moss tundra (MNT). The two MNT grids are similar. Back to: Patterned-Ground 10 x 10 m Grids (Raynolds et al. 2005) Go to Website :: Biocomplexity of Frost Boil Ecosystems below for more information.

    Description

    list("Snow is a crucial resource for billions of people on Earth. We proposed a study of snow drifts. Drifts can comprise more than half of the local snow water equivalent (SWE) and play a large and widely overlooked role in snow hydrology. They melt slowly, resulting in a crucial shift in the timing of water delivery that syncs snow melt directly to agricultural and ecosystem needs, yet we know little about drifts on either local or global scales. The overall goal of the research was to better understand the role and importance of snow drifts in hydrology. Using lidar and structure-from-motion (SfM) photogrammetry, we conducted an airborne study of drifts coupled with extensive ground validation in search of preliminary answers to questions on the importance of drifts and the percentage of SWE found in drifts in a variety of terrain types.", "The snow depth maps hosted here represent six years of drift records from northern Alaska and enable the analysis of the relationships between drifts and the surrounding snowcover and the landscape below, as well as drift persistence over time.", "Snow depth mapping was done using airborne SfM photogrammetry (2015 through 2018) and lidar (2012 and 2013) and then adjusted to ground-based probe measurements of snow depth. The area mapped each year over two swaths was about 130 kilometer squared (km^2). To produce the maps, we: (1) conducted an airborne survey (snow-free) in June that was used to produce a snow-free digital elevation model (DEM) for each swath, (2) conducted airborne surveys at near-peak snow cover each April that were used to create digital surface models (DSMs) of the snow cover, then (3) generated annual high resolution (1 m) snow depth maps by subtracting the snow-free DEM from the DSMs. Six such depth maps were produced for each swath between 2012 and 2018, comprising over 600 million individual geospatial snow depth records. Acquiring the snow-free DEM required careful timing because tundra plants leaf out before all snowdrifts melt. The snow depth maps were field-validated and adjusted using 141,207 ground-based probe measurements collected concurrently with the airborne surveys.", "There are twelve (12) snow depth raster maps deposited here. Each map represents the near-peak annual snow depth across a swath of Arctic tundra. There are two swaths: CLPX (a zone that was part of a Cold Land Experimental Site - a NASA snow measurement program that rotates through several different field areas) and HV (Happy Valley). Map years include 2012, 2013, 2015, 2016, 2017, and 2018. Maps are raster data GeoTIFF file formats where each pixel is one by one meter square. The file naming convention is swathdepthDOY_*YYYY*_corrected_*correction_amount*.tif.")

    Description

    The West Dock biocomplexity grid is located near the water pumping facility at West Dock in the Prudhoe Bay oilfield, AK, within 1 km of the Beaufort Sea coast. There is one 10 x 10 m grid with nontussock sedge, prostrate dwarf-shrub, moss tundra on sandy soils.
