![]() ![]() If you have 91.456 degrees you can see that your measurement is 91 whole degress plus 0.456 of a degree. One degree has 60 minutes and one minute has 60 seconds. Why multiply decimal degrees by 60 to get minutes and seconds?Ĭircles and spheres have 360 degrees in a complete rotation. If your resulting seconds is something like 31.9 you may round up to 32. Decimal degrees 156.742 converts to 156 degrees, 44 minutes and 31 seconds, or 156° 44' 31".īe sure to follow math rules of rounding when calculating seconds by hand.If there is still a decimal remaining you can round up or down to the whole number of seconds.Įxample: Convert decimal degrees 156.742 to degrees minutes seconds.Multiply the decimal part by 60 to get seconds. The decimal of this result is decimal minutes which you want to convert to seconds.The whole number part of the result is minutes. The decimal part is decimal degrees which you want to convert to minutes.The whole number part of your decimal degrees gives you degrees.So the conversion factor for each decimal is to multiply by 60. There are 60 minutes per degree, and 60 seconds per minute. Input decimal degrees ( DD) and click Calculate to convert the decimal to degrees, minutes, seconds ( DMS) and degrees, decimal minutes ( DMM). The function convertProjectedToLatLon will return the latitude and longitude in the WGS84 coordinate system.Convert degrees in decimal form such as GPS coordinates in latitude and longitude to degrees, minutes and seconds ( DMS). Just replace x, y, and sourceEpsg with your coordinates and EPSG code, respectively. import pyprojĭef convert_projected_to_latlon(x, y, source_epsg, dest_epsg=4326): You can change these codes according to your requirements. In this example, I am using the UTM Zone 32N (EPSG:32632) as the source coordinate system, and WGS84 (EPSG:4326) as the destination coordinate system. Make sure you know the EPSG (European Petroleum Survey Group) codes for both the source and destination coordinate systems. Next, you can use the following Python script to perform the conversion. First, you need to install the library if you haven’t done so already: pip install pyproj To convert projected coordinates to latitude and longitude using Python, you can use the pyproj library, which is a wrapper around the PROJ library. Want to stay ahead of the geospatial curve? Listen to our podcast! Converting projected coordinates to lat/lon using Python Libraries like pyproj in Python, sf in R, and proj4js in JavaScript are commonly used to perform these conversions. The conversion process requires knowledge of the source (projected) and destination (geographic) coordinate systems, and sometimes additional parameters, such as the datum or projection parameters. ![]() This conversion is essential when you need to perform tasks that involve geospatial data in different coordinate systems, such as overlaying data from various sources, calculating distances, or performing spatial analyses. When you convert projected coordinates to latitude and longitude, you are transforming coordinates from a flat, Cartesian grid to a curved coordinate system that takes into account the Earth’s shape. ![]() The most commonly used geographic coordinate system is the World Geodetic System 1984 (WGS84). In this system, latitude is the angle measured from the equator to a point on the Earth’s surface, while longitude is the angle measured from the Prime Meridian (which passes through Greenwich, England) to a point on the Earth’s surface. Latitude and longitude (lat/lon) are part of a geographic coordinate system that represents points on the Earth’s surface using angles. Examples of projected coordinate systems include Universal Transverse Mercator (UTM), State Plane Coordinate System (SPCS), and Lambert Conformal Conic. They are especially useful for regional or local mapping, where distortions introduced by the projection are minimal. Projected coordinate systems are used to represent the Earth’s curved surface on a flat plane. What is the difference between projected coordinates and latitude and longitudeĬonverting projected coordinates to latitude and longitude (lat/lon) means transforming coordinates from a two-dimensional, Cartesian coordinate system to a geographic coordinate system based on a sphere or ellipsoid (such as Earth). ![]()
