Fraser Lowland
The Fraser Lowland is a landform and physiographic region in the Pacific Northwest of North America, shared between the Canadian province of British Columbia and the U.S. state of Washington. The region includes much of the Lower Mainland region of British Columbia, and the coastal plains of Washington's Whatcom County. As a physiographic region, the Fraser Lowland is part of the Georgia Depression, which in turn is part of the Coastal Trough.''Landforms of British Columbia: A Physiographic Outline'', by S.

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Plain
A coastal plain is flat, low-lying land adjacent to a sea coast. A fall line commonly marks the border between a coastal plain and a piedmont area. Some of the largest coastal plains are in Alaska and the southeastern United States. The Gulf Coastal Plain of North America extends northwards from the Gulf of Mexico along the Lower Mississippi River to the Ohio River, which is a distance of about . The Atlantic Coastal Plain runs from the New York Bight to Florida. The Coastal Plains of India lie on either side of the Deccan Plateau, along the western and eastern coasts of India. They extend for about 6,150 km from the Rann of Kutch in the west to West Bengal in the east. They are broadly divided into the Western Coastal Plains and the Eastern Coastal Plains. The two coastal plains meet at Kanyakumari, the southernmost tip of the Indian mainland. The eastern coastal plain is located between The Bay of Bengal and the eastern Ghats and the western coastal plain is located between ...

Nooksack Valley
The Nooksack Valley refers the collection of mountain valleys within the North Cascades centered around Mount Shuksan, Mount Baker and the Twin Sisters, formed by the catchments of the upper Nooksack River and its alpine tributaries (primarily the North Fork, Middle Fork and South Fork). Roughly covering the western half of Washington state's Whatcom County and a small northern fringe of Skagit County, the Nooksack valleys expands between the Sumas Mountain and Stewart Mountain (between which the valley ''proper'' is located) to the west; the Red Mountain, Church Mountain and Goat Mountain in the north; the Ruth Mountain, Icy Peak and Nooksack Cirque in the east; and the Lyman Hill and Mount Josephine in the south. Out of the three main tributary valleys, the North Fork Valley communicates with the Columbia Valley in the north via a decently wide mountain pass between the Sumas and Red Mountain, where the Washington State Route 547 goes through from Kendall to Peaceful Valley ...
