   One of the most difficult aspects of the real estate market is estimating the value of a home. With local market conditions changing all the time, it can be hard to accurately price a property. In ...

3. Triangulation (surveying) - Wikipedia

   en.wikipedia.org/wiki/Triangulation_(surveying)

   Triangulation of Kodiak Island in Alaska in 1929. In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline by using trigonometry, rather than measuring distances to the point directly as in trilateration.

4. Triangulation - Wikipedia

   en.wikipedia.org/wiki/Triangulation

   Measuring the height of a building with an inclinometer. Triangulation today is used for many purposes, including surveying, navigation, metrology, astrometry, binocular vision, model rocketry and, in the military, the gun direction, the trajectory and distribution of fire power of weapons. The use of triangles to estimate distances dates to ...

5. Altimeter - Wikipedia

   en.wikipedia.org/wiki/Altimeter

   Reference pressure of about 29.92 inHg (1013 hPa) is showing in the Kollsman window. An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. [1] The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water.

6. Benchmark (surveying) - Wikipedia

   en.wikipedia.org/wiki/Benchmark_(surveying)

   A benchmark is a type of survey marker. The term is generally applied to any item used to mark a point as an elevation reference. Frequently, bronze or aluminum disks are set in stone or concrete, or on rods driven deeply into the earth to provide a stable elevation point. If an elevation is marked on a map, but there is no physical mark on the ...

7. Total station - Wikipedia

   en.wikipedia.org/wiki/Total_station

   Total stations are the primary survey instrument used in mining surveying. A total station is used to record the absolute location of the tunnel walls, ceilings (backs), and floors, as the drifts of an underground mine are driven. The recorded data are then downloaded into a CAD program and compared to the designed layout of the tunnel.

8. Digital elevation model - Wikipedia

   en.wikipedia.org/wiki/Digital_elevation_model

   A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems (GIS), and are the most common basis ...

9. Height above mean sea level - Wikipedia

   en.wikipedia.org/wiki/Height_above_mean_sea_level

   Height above mean sea level. Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and ...
