Apex Mountain Resort is a ski resort in southwestern Canada , located in the Okanagan region on Beaconsfield Mountain, just west of Penticton , British Columbia . Its first Pomalift was installed in 1961, with a vertical rise of 370 m (1,200 ft).
15-495: Beaconsfield Mountain has a summit elevation of 2,178 m (7,146 ft) above sea level and receives an average of 600 cm (20 ft) of snow a year. It has 4.5 km (1,112 acres) of groomed, skiable terrain, 50 km (20 sq mi) of backcountry skiing terrain, and 50 km (30 mi) of groomed cross-country terrain. There are 79 named trails accessed by four chairlifts , including one high-speed quad . The resort also offers four terrain parks and
30-589: A geodetic datum that binds the coordinate system to actual locations on the Earth. The ECEF that is used for the Global Positioning System (GPS) is the geocentric WGS 84 , which currently includes its own ellipsoid definition. Other local datums such as NAD 83 may also be used. Due to differences between datums, the ECEF coordinates for a location will be different for different datums, although
45-1996: A tube park. Apex currently operates twelve snow guns that provide top-to-bottom snowmaking capability. The mountain's main accommodation providers include Stay at Apex, Apex Lodge, and Apex Mountain Inn. Other activities that the resort provides include a 1.0 km (0.6 mi) skating loop and a hockey rink. Nearby, Nickel Plate Nordic Centre also offers snowshoeing and cross-country skiing.

60-479: A 3D Elevation Program (3DEP) to keep up with growing needs for high quality topographic data. 3DEP is a collection of enhanced elevation data in the form of high quality LiDAR data over the conterminous United States, Hawaii, and the U.S. territories. There are three bare earth DEM layers in 3DEP which are nationally seamless at the resolution of 1/3, 1, and 2 arcseconds. ECEF The Earth-centered, Earth-fixed coordinate system (acronym ECEF ), also known as

You can help Misplaced Pages by expanding it . Elevation The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid , a mathematical model of
90-475: Is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge , the summits of Mount Everest and Chimborazo have, respectively, the largest elevation and the largest geocentric distance. In aviation, the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of
105-448: Is the main type of map used to depict elevation, often through contour lines . In a Geographic Information System (GIS), digital elevation models (DEM) are commonly used to represent the surface (topography) of a place, through a raster (grid) dataset of elevations. Digital terrain models are another way to represent terrain in GIS. USGS (United States Geologic Survey) is developing
120-456: The Earth 's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum ). The term elevation is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface. Elevation
135-403: The geocentric coordinate system , is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface , interior, atmosphere , and surrounding outer space) as X , Y , and Z measurements from its center of mass . Its most common use is in tracking the orbits of satellites and in satellite navigation systems for measuring locations on
150-461: The aerodrome. It is not to be confused with terms such as the altitude or height. GIS or geographic information system is a computer system that allows for visualizing, manipulating, capturing, and storage of data with associated attributes. GIS offers better understanding of patterns and relationships of the landscape at different scales. Tools inside the GIS allow for manipulation of data for spatial analysis or cartography. A topographical map
165-436: The difference between the two aforementioned quantities: h ′ = R − R 0 ; it is not to be confused for the geodetic altitude . Conversions between ECEF and geodetic coordinates (latitude and longitude) are discussed at geographic coordinate conversion . As with any spatial reference system , ECEF consists of an abstract coordinate system (in this case, a conventional three-dimensional right-handed system), and

#1732781072984180-560: The differences between most modern datums is relatively small, within a few meters. The ECEF coordinate system has the following parameters: An example is the NGS data for a brass disk near Donner Summit, in California. Given the dimensions of the ellipsoid, the conversion from lat/lon/height-above-ellipsoid coordinates to X-Y-Z is straightforward—calculate the X-Y-Z for the given lat-lon on
195-573: The point is within 10,000 meters above or 5,000 meters below the ellipsoid. Geocentric coordinates can be used for locating astronomical objects in the Solar System in three dimensions along the Cartesian X, Y, and Z axes . They are differentiated from topocentric coordinates , which use the observer's location as the reference point for bearings in altitude and azimuth . For nearby stars , astronomers use heliocentric coordinates, with
210-423: The surface of the Earth, but it is also used in applications such as tracking crustal motion. The distance from a given point of interest to the center of Earth is called the geocentric distance , R = ( X + Y + Z ) , which is a generalization of the geocentric radius , R 0 , not restricted to points on the reference ellipsoid surface. The geocentric altitude is a type of altitude defined as
225-439: The surface of the ellipsoid and add the X-Y-Z vector that is perpendicular to the ellipsoid there and has length equal to the point's height above the ellipsoid. The reverse conversion is harder: given X-Y-Z can immediately get longitude, but no closed formula for latitude and height exists. See " Geodetic system ." Using Bowring's formula in 1976 Survey Review the first iteration gives latitude correct within 10 degree as long as
