What projection uses decimal degrees?

Geographic coordinate systems
Geographic coordinate systems (GCS) use units of decimal degrees for coordinates. These units are often referred to as ‘lat’ and ‘long’. Decimal degrees (DD) are angles, and these units of measure are often used with GIS data but rarely with CAD data.

Why are decimal degrees used in GIS?

A value in decimal degrees to 5 decimal places is accurate to 1.11 meter at the equator. Because the earth is a spheroid and not flat, the accuracy of the longitude part of the coordinates increases the further from the equator you get. The accuracy of the latitude part does not increase.

How to convert degrees to decimal in ArcGIS 10?

The formula for converting Degree Minutes and Seconds to Decimal Degrees is discussed in the ArcGIS 10 Help. Another common method is to use a projected coordinate system and X and Y coordinate pairs, that is, two sets of numbers in a planar Cartesian system.

How to convert state plane coordinates to decimal degrees?

Under “Coordinate System of Input Coordinates” select “Edit…” and choose the correct coordinate system. 3.) Once your points are plotted, right click your plotted data in the table of contents and select data -> Export Data. Save the plotted points to a shapefile and add it to your map. 4.) Reproject the shapefile to the desired projection.

How to convert XY coordinates to decimal degrees in Excel?

Since you have ArcGIS 10.1 available, it would be easy to import your current data in excel format, plot the XY coordinates in the current coordinate system, reproject your points to your desired coordinate system, and then export the data back to a new spreadsheet. 1.) Add your existing spreadsheet to ArcMap

How do you convert latitude to longitude in ArcMap?

Create a table in a file geodatabase with the field names Latitude and Longitude, with Long Integer as the data type. Edit the table and enter in the points in decimal degrees. Manually convert the degrees-minutes-seconds to decimal degree values using the Field Calculator in ArcMap.
