Remember that x is longitude (East/West), and y is latitude (North/South)-the same order in which coordinates are listed in the status bar. These apply to Absolute XY and commands such as Move To that allows you to move a vertex or topology element to an exact location. Below are some guidelines for specifying these values. These are the same formats used by the Go To XY command. Map units are the default, but you can click the Units button to choose the units in which to enter coordinates. National Grid (USNG) location, or a Universal Transverse Mercator (UTM) coordinate. In commands that require you to enter a specific location when editing, you can specify the location as a longitude-latitude coordinate pair, a Military Grid Reference System (MGRS) grid location, a U.S. survey units Entering specific locations (DD, DMS, DDM, MGRS, USNG, and UTM) An exact conversion to meters can be accomplished by multiplying U.S. In the United States, fundamental survey units, such as rods, chains, statute miles, acres, sections, and townships, all depend on the U.S. survey foot is used in the state plane coordinate systems. In ArcGIS Desktop the United States nautical mile is used, whichġ/100 international chain, or 66/100 international feet. The nautical mile is defined as the averageĭistance on the earth's surface represented by one minute of The nautical mile is a unit of distance used primarily in sea countries before the metric system.Īlso referred to as a statute mile, equal to 5,280 international feet. Metric units Imperial or international units Distance unitsĪlso known as international foot or imperial foot that was used in most non-U.S. The following sections outline all the unit abbreviations supported when editing and describe how to implement them. Unit abbreviations only work when your data frame uses a projected coordinate system rather than a geographic coordinate system. Whenever you are typing a distance into one of the editing tools, you have the option to specify the linear units or simply type a number, which the tool will interpret as being in map units. survey feet, you can type the abbreviation for meters, m, after the measurements, and the tools will convert the distance correctly. Rather than convert all the measurements to U.S. When you input measurements, in many cases it is possible to enter values in units other than map units by specifying a units abbreviation with the value.įor example, suppose your data is in a State Plane coordinate system and the linear units are U.S. Sometimes when creating features, you need to enter values that were recorded in different distance units than the coordinate system of your data. You can find out the map units used by your coordinate system on the Data Frame Properties dialog box > General tab. When editing, all the values you enter will be in map units by default. The map units are determined by the coordinate system of the data frame. The map units are the units in which the spatial data in the data frame is drawn. When editing, the map units of your data frame are used when reporting and entering measurements and distances. Entering specific locations (DD, DMS, DDM, MGRS, USNG, and UTM).
