![]() However when I use that tool and put numbers I got into Google Maps, it pointed area where not even close to area A.Īnd this is lat and lng inside of area A, the format of expected numbers. At first I thought that those are map x and map y, because one time data source gave me that kinds of numbers and I had to find tool to convert it into lat and lng. So, the numbers very strange, the area A supposed to have like lat 35.XXXXX and lng 127.XXXXX and what I got was something like x: 12834.6278 and y:3551.5214. I have to figure it out what is it and have to convert it into lat and lng that you can use it in Google Maps. I know there are several different values like map xy, so I think those are one of the Geographic coordinate system that I don't know. I received some Excel files from a data source that supposed to contains some buildings' lat and lng in area A, and what I got was just have x and y (I don't know what does it mean). Thanks in advance for your contribution to improve this site (please correct the errors of grammar and translation).I'm new to GIS, and I have some tasks that have to work with lat and lng values.

Precision choice is of 5 decimal place is accurate to 1.11 meter (+/- 55.5 cm) at the equator. The accuracy of the latitude remains almost unchanged. The accuracy of the longitude increases the further from the equator you get. The Earth is not a sphere, but an irregular shape approximating an ellipsoid. Latitude and Longitude have the maximum error in the equator, because the earth' radius is maximum. Search on map Click on search to open the webpage Earth Coordinate, here you obtain the latitude and longitude simply by clicking on the map, and save the value by the button save. Coordinates Coordinates format is the pair of latitude and longitude, with sign minus (-) for the direction south latitude and west longitude separate by comma symbol (,), here some example: Seconds is a double value without sign, from 0 (or 0.0000) to 59.9999. Minute is an integer value without sign, from 0 to 59. Degree Degree format is composed of direction (N-S or W-E) and three sets of numbers separate by the symbols for degrees (°), minutes (’), and seconds (").ĭegree is an integer value without sign, from 0 to 90 for the latitude or from 0 to 180 for the longitude. Decimal You have to select a direction (N-S or W-E) and insert a number from 0 to 90 for the latitude or from 0 to 180 for the longitude (example 45.12345). # Sum the degrees to the decimal using the symbols for degrees (°) (-73.9874°)įormat Value range Valid value for the latitude are from -90.0° to 90.0° for the longitude are from -180.0° to 180.0°, the + sign should be omitted, while the minus sign is not necessary if there is a radio component to select the direction N-S or W-E (Degree and Decimal format). # The resulting is the decimal value of degrees (0.9874) # Sum the resulting to the minute and divide by 60 (59.244/60 = 0.9874) # The whole units of degrees will remain the same How to convert from a sexagesimal to decimal # Take your three sets of numbers and put them together, using the symbols for degrees (°), minutes (’), and seconds (") (-73° 59’ 14.64" longitude) # The resulting number becomes the seconds (14.64"). # Take the remaining decimal and multiply by 60. # The whole number becomes the minutes (59’) # The whole units of degrees will remain the same (-73.9874° longitude, start with 73°) The numerical values for latitude and longitude can occur in a number of.
