Fraser River Valley
The Fraser Valley is a geographical region in southwestern British Columbia, Canada and northwestern Washington State. It starts just west of Hope in a narrow valley encompassing the Fraser River and ends at the Pacific Ocean stretching from the North Shore Mountains, opposite the city of Vancouver BC, to just south of Bellingham, Washington. In casual usage it typically describes the Fraser River basin downstream of the Fraser Canyon. The term is sometimes used outside British Columbia to refer to the entire Fraser River sections including the Fraser Canyon and up from there to its headwaters, but in general British Columbian usage the term refers to the stretch of Lower Mainland west of the Coquihalla River mouth at the inland town of Hope, and includes all of the Canadian portion of the Fraser Lowland as well as the valleys and upland areas flanking it. It is divided into the Upper Fraser Valley and Lower Fraser Valley by the Vedder River mouth at the eastern foothills of 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] |
Valley
A valley is an elongated low area often running between Hill, hills or Mountain, mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms th ...

Greater Vancouver
Greater Vancouver, also known as Metro Vancouver, is the metropolitan area with its major urban centre being the city of Vancouver, British Columbia, Canada. The term "Greater Vancouver" is roughly coterminous with the geographic area governed by the Metro Vancouver Regional District, though it predates the 1966 creation of the regional district. It is often used to include areas beyond the boundaries of the regional district but does not generally include wilderness and agricultural areas within that regional district. Usage of the term "Greater Vancouver" is not consistent. In local use it tends to refer to urban and suburban areas only, and does not include parts of the regional district such as Bowen Island, although industries such as the film industry even include Squamish, Whistler and Hope as being in "the Vancouver area" or "in Greater Vancouver". The business community often includes adjoining towns and cities such as Mission, Chilliwack, Abbotsford and Squamish wit ...

Population Centre
In demographics, the center of population (or population center) of a region is a geographical point that describes a centerpoint of the region's population. There are several ways of defining such a "center point", leading to different geographical locations; these are often confused. Definitions Three commonly used (but different) center points are: # the ''mean center'', also known as the ''centroid'' or ''center of gravity''; # the '' median center'', which is the intersection of the median longitude and median latitude; # the ''geometric median'', also known as ''Weber point'', ''Fermat–Weber point'', or ''point of minimum aggregate travel''. A further complication is caused by the curved shape of the Earth. Different center points are obtained depending on whether the center is computed in three-dimensional space, or restricted to the curved surface, or computed using a flat map projection. Mean center The mean center, or centroid, is the point on which a rigid, weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Regional District
In the province of British Columbia in Canada, a regional district is an administrative subdivision of the province that consists of a geographic region with specific boundaries and governmental authority. there were 28 regional districts in the province. History Regional districts came into being as an order of government in 1965 with the enactment of amendments to the Municipal Act. Until the creation of regional districts, the only local form of government in British Columbia was incorporated municipalities, and services in areas outside municipal boundaries had to be sought from the province or through improvement districts. Government structure Similar to counties in other parts of Canada, regional districts serve only to provide municipal services as the local government in areas not incorporated into a municipality, and in certain regional affairs of shared concern between residents of unincorporated areas and those in the municipalities such as a stakeholder role in r ...

Fort Langley
Fort Langley is a village community in Township of Langley, British Columbia, Canada. It has a population of approximately 3,400 people. It is the home of Fort Langley National Historic Site, a former fur trade post of the Hudson's Bay Company. Lying on the Fraser River, Fort Langley is at the northern edge of the Township of Langley. History Fort Langley was named after Thomas Langley, a director with HBC. and dates from a time when the boundary between British and American possession of the trans-mountain west, known as the Columbia District to the British and Oregon Country to Americans, had not yet been decided. Sir George Simpson, Governor of the Hudson's Bay Company, realized that Fort Vancouver opposite of present-day Portland, Oregon might be lost to the Americans if the border did not follow the Columbia River. Fearing the 49th parallel north could become the demarcation line, Simpson ordered the Hudson's Bay Company to construct the original Fort Langley in 1827 a ...

Salmon River (Langley)
The Salmon River is a small river in the Township of Langley in the Lower Mainland region of British Columbia, Canada, flowing northwest then northeast to enter Bedford Channel, which separates McMillan Island from Fort Langley, which is just southwest. The river is one of the only fish stock sustaining streams remaining in the Metro Vancouver area. History The Salmon River was an important route for First Nations peoples and later settlers. It was used for trade and transportation, connecting the Fort Langley settlers and indigenous peoples with Mud Bay and the Straight of Georgia via a portage to the Nicomekl River The Nicomekl River springs from the ground in Langley, British Columbia and travels west through the city to Surrey's Crescent Beach, where it empties into Mud Bay, the northernmost section of the Boundary Bay of the Strait of Georgia. It has a .... The river and its watershed provided salmon for use in trade and fostered the establishment of a prosperous comm ...

McMillan Island
McMillan Island is an island in the Fraser River, British Columbia, Canada, also known as McMillan Slough.. Geography Overview McMillan Island is located in the lower Fraser River, north of Fort Langley and south of Maple Ridge, and separated from the former by Bedford Channel. It has a total land area of 1.78 square kilometres. Geology It is composed primarily of settled silt and debris from the Fraser River and shaped by the erosive power of the river. Geologically it was (10000 years ago) a peninsula on the shore of what is now Maple Ridge. Erosion wore down the peninsula until it became an island, although one much larger than the current McMillan Island. Once there was a channel worn between this large island and the mainland, the water flow slowed and silt and debris settled on the south side of the island, eventually connecting it to what is now Fort Langley. The water eventually broke a small section of the original island off, resulting in the current McMillan Isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumas Mountain (British Columbia)
Sumas Mountain, also referred to as Canadian Sumas to distinguish it from an identically-named mountain just to the south in U.S. state of Washington across the border, is a mountain in eastern Fraser Lowland, in the Lower Mainland region of the Canadian province of British Columbia. It sits on the south bank of the Fraser River, west of the smaller Chilliwack Mountain across the Vedder River mouth, and serves as a geographic landmark dividing the Fraser Valley into "Upper" and "Lower" sections. The mountain is separated from the Vedder Mountain and the North Cascades by the drained Sumas Lake, now a flatland called Sumas Prairie that is part of the greater floodplain of the Fraser River basin, south of which is a same-named sister mountain ( American Sumas) in Washington state's Whatcom County. West of the mountain is Matsqui Prairie, another floodplain, and north of the Fraser, which lies along the mountain's north flank, are similar floodplains - Nicomen Island and Hatzic ...
