Easton Airport ( IATA : ESN , ICAO : KESN , FAA LID : ESN ), also known as Easton/Newnam Field , is a county-owned, public-use airport located two nautical miles (4 km, or 2.5 miles) north of the central business district of Easton , a town in Talbot County , Maryland , United States .
6-580: Easton Airport covers an area of 615 acres (249 ha) at an elevation of 72 feet (22 m) above mean sea level . It has two asphalt paved runways : 4/22 measuring 5,500 x 100 ft (1,676 x 30 m) and 15/33 measuring 4,003 x 100 ft. (1,220 x 30 m). There are precision approaches on runway 4 and 22. Runway 4 uses an ILS approach while runway 22 uses a GPS or NDB approach. All four runways use PAPI precision approach lights to help guide pilots on their final approach on landing. As of late 2007, an Air traffic control tower has been built on field, due to
12-560: Is based at Easton Airport. 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 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
18-404: 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 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,
24-714: The increasing number of aircraft at Easton Airport. Easton is now a Class D (Delta) controlled airport with a ceiling of 2,600 feet. For the 12-month period ending June 27, 2022, the airport had 73,201 aircraft operations, an average of 200 per day: 76% general aviation , 19% military , and 5% air taxi . At that time there were 180 aircraft based at this airport: 135 single- engine , 26 multi-engine, 14 jet and 2 helicopter , and 3 gliders. On field services include: 100LL and Jet A fuel, aircraft rental, aircraft sales, aircraft maintenance, aerial photography, flight school, charter flights, car rental, oxygen and T-hangars.

30-582: The landscape at different scales. Tools inside the GIS allow for manipulation of data for spatial analysis or cartography. A topographical map 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)
36-545: 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 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
