The problem: Sometimes you have geographic data that consists only of latitudes and longitudes, but you want to know the altitudes as well — because, for example, you want to colorize points by height above sea level, or draw a profile of a track. Here are some common reasons why you might have flat or incomplete data
- The GPS uses height (h) above the reference ellipsoid that approximates the earth's surface. The traditional, orthometric height (H) GPS uses an ellipsoid coordinate system for both its horizontal and vertical datums. The GPS receiver uses a theoretical sea level estimated by a World Geodetic System (WGS84).

For example, if the +/-0,0000 level of your project is at the height of +110,5000 meters above sea level, you would enter -110,5000 for value in this field. Sea Level reference level.

Many KML features can contain an <altitude> element or coordinate, which specifies a distance above the ground level, sea level, or sea floor for that particular feature.<AbstractView> elements also can contain altitude. Any altitude value should be accompanied by an <altitudeMode> element, which tells Google Earth how to read the altitude value The GPS Height tab is used to specify heights and height units to be used by ArcPad when calculating z-coordinate values. ArcPad calculates heights in one of two formats: Height above ellipsoid (HAE). This is the default. Height above Mean Sea Level (MSL) if a geoid separation value is specified Find Elevation. Find elevation by searching a locations address or latitude longitude. Bellow shows the top 100 mountains with the highest elevation

Values for antenna height above average terrain (commonly abbreviated HAAT) can be calculated using this form. Two terrain databases are available here: the FCC's legacy 30-second terrain database, and the GLOBE 1 km Base Elevation database from the National Geophysical Data Center. Using GLOBE, HAAT values can be calculated for any location on Earth, given coordinates an The height of the geoid above the ellipsoid, N, is sometimes called the geoid undulation. It can be used to convert a height above the ellipsoid, h, to the corresponding height above the geoid (the orthometric height, roughly the height above mean sea level), H, using the relations h = N + H; H = −N + h Distance **above** **sea** **level** (8) Synonyms, crossword answers and other related words for **HEIGHT** **ABOVE** **SEA** **LEVEL** [altitude] We hope that the following list of synonyms for the word altitude will help you to finish your crossword today Historically in New Zealand, heights have been defined in terms of 13 local vertical datums referenced to local mean sea level (MSL). The 13 local vertical datums were established by determining mean sea level at a tide-gauge and then transferring this level to benchmarks in a network

This information can be useful to travellers, sailors, tourists, students, teachers and other people who need to know the geographic coordinates of and its height above sea level The height of 800 meters is detrimental to health of some people. measurement by the satellite map is that there is no need in independent determination and computation of geographical coordinates and altitude above sea-level with the aid of barometer, tables or formulas Please also see ele =* for tagging elevation data. Altitude is usually referred to as the height above ground. NOTE: This page calls for using WGS84 height compared to the ellipsoid while the ele =* page calls for using meters above above mean sea level as defined by the EGM96 geoid model.. OSM currently records points with their latitude and longitude (x/y coordinates); elevations are. Measuring heights with GPS and GPS internal barometers is a common issue. Here are some of our own measurements and thoughts on this issue. The test case was a well known coordinate 46.5 m above sea level. The GPS was a GARMIN etrex VISTA HCX (which is for rent here)

Earth radius at sea level is 6378.137 km (3963.191 mi) at the equator. It is 6356.752 km (3949.903 mi) at the poles and 6371.001 km (3958.756 mi) on average.

This specifies whether values are positive up, representing heights above a surface, or positive down, indicating that values are depths below a surface. The following diagram shows two vertical coordinate systems: mean sea level and mean low water

In aviation, atmospheric sciences and broadcasting, a height above ground level (AGL or HAGL) is a height measured with respect to the underlying ground surface.This is as opposed to height above mean sea level (AMSL or HAMSL), or (in broadcast engineering) height above average terrain (AAT or HAAT). In other words, these expressions (AGL, AMSL, AAT) indicate where the zero level or. (Benchmarks are stable marks placed on the ground which have known heights above sea level - they are sometimes called vertical control points.) Therefore heights that are given in relation to the national height datum are heights above the Geoid (or very close to this) Instead, Y=63 is the Overworld water sea level, Y=31 is the Nether lava sea, and Y=11 is the overworld lava flood sea. To clarify: The sea level is 63, 11, or 31, which refers to the block position of top water/lava is 62, 10, or 30. The player's coordinates are actually the coordinates of the center at the bottom of player's collision box Ellipsoidal heights have to be adjusted before they can be compared to orthometric (mean sea level) heights. Geoid undulations (N) are used to adjust the ellipsoidal heights (H = h - N). Height h above the reference ellipsoid and height H above the Geoid for two points on the Earth surface

It also transforms GPS ellipsoid heights to orthometric (mean sea level) heights on the relevant Ordnance Survey mapping datum (Ordnance Datum Newlyn for mainland Britain), using the National Geoid Model OSGM15. For more information on coordinate systems and transformations see our publication A guide to coordinate systems in Great Britain You can assign more accurate altitudes for your saved locations, called placemarks, in Google Earth for your computer. You can change altitudes for a single placemark or all placemarks in a folder. Note: Folders can have placemarks with different altitude settings.In this case, the folder's altitude setting shows as Mixed Modes Mean Sea Level (MSL): It is the arithmetic mean height of the sea in reference to a surface such as a chart datum, ellipsoid or geoid. It is determined from hourly observations over an 18.6 year cycle to average out the tidal lows and highs caused principally by the gravitational forces from the moon and sun ele =*. Elevation (height above sea level) of a point, in metres. This is mainly intended for mountain peaks but could also be used for elevation of airport runways and many other objects. For OpenStreetMap, this value should be in metres above above mean sea level as defined by the EGM96 geoid model. This elevation is usually very close to national above sea level systems with differences < 1m Heights. Heights are usually shown on maps by contour lines or spot heights and they give the height above Mean Sea Level (MSL). MSL can vary slightly with time and from place to place, so in Australia a Mean Sea Level value measured in 1966-1968 at 30 tide gauges around the country is used as the reference for height measurement

Other systems are placed under the water and measure the water pressure which is converted to the height of the water column above the sensor. At a particular port the level of the water is expressed as a height above a local datum which is also the datum used for the depths of the sea on nautical charts The vertical distance of a level, a point, or an object considered as a point, measured from mean sea level (ICAO). In the case of aircraft in flight, it is normally expressed in flight levels or hundreds of feet.

GCOOS 52North Sensor Observation Service - Data Access for the Sensor Web This station provides the following variables: Sea surface height above sea level sos JPE SEA LEVEL or, as it is more usually called, mean sea level, is the average height of the surface of the sea. As the tide rises and falls, hourly observations of the height of the sea on an open coast are conducted over a 19-year period. When people talk about elevation, they mean the height of a point above or below mean sea level The Reconstructed Sea Level dataset contains sea level anomalies derived from satellite altimetry and tide gauges. The satellite altimetric record provides accurate measurements of sea level with near-global coverage, but it has a relatively short time span, since 1993. Tide gauges have measured sea level over the last 200 years, with some records extending back to 1807, but they only provide.

For clarity I would refer to this true altitude as height above mean sea level. - Brian Nixon Mar 17 '11 at 22:29 @Brian Nixon - I disagree that the word altitude has any intrinsic relation to a barometric measurement other than the fact that it is frequently calculated that way in certain domains The vertical datum is similarly realized through a collection of specific points on the Earth with known heights either above or below a nationally defined reference surface (e.g., mean sea level). Geodetic vertical datums are generally used to express land elevations When it is stated that sea level is rising, this usually refers to mean sea level, which is the average sea level around the earth based on numerous measurements over a long period of time. The elevation of mountain peaks are measured as the height of the peak of the mountain above mean sea level Its height, in meters, above sea level, as a function of time, in seconds, is given by h(t)=-4.9 t^{2}+229 t+234 .
