How do you convert NAD 83 to WGS 84?

How to convert coordinates from NAD83 to WGS84

Select input\output spatial references.
Input coordinates using decimal format.
Click on ‘Transform’ button to convert coordinates.
Your coordinates will be converted using the output spatial reference.

Are NAD83 and WGS84 the same?

Answer: There are a number of difference between the NAD83 and the WGS84 datum. The North American 1983 datum (NAD83) uses the Geodetic Reference System (GRS80) ellipsoid while the World Geodetic System of 1984 (WGS84) uses the WGS 84 ellipsoid. The dimensions of these ellipsoids differ slightly.

How do you convert coordinate systems in ArcGIS?

Change a Coordinate System in a Map Layer

Open ArcToolbox.
Open Data Management Tools → Projections and Transformations → Feature → Project.
Choose the Projected Coordinate System folder or the Geographic Coodinate System folder, depending upon the Coordinate Systems of your other files and how you want to match them.

How do I change my datum in ArcGIS?

Procedure

In ArcMap, go to View > Data Frame Properties dialog.
Select the Coordinate System tab.
Click the Transformations button at the bottom of the dialog (in older versions of the software, the Transformations button appears on the right.)
Select one of the listed transformations.

How far off are NAD83 and WGS84?

If you are involved with such a precise project where the 3-4 feet of difference between WGS84 and NAD83 are important, you are probably using an RTK GPS system, hence you have to set-up a base station.

Which is better NAD83 or WGS84?

WGS84 has error less than 2cm from center of mass which is better than NAD83. 5. One other main difference between WGS84 and NAD83 is points over Northern American plate for NAD83 does not change whereas WGS84 is defined with respect to average of stations all over the world. 6.

How do you convert between coordinate systems?

To convert a point from cylindrical coordinates to Cartesian coordinates, use equations x=rcosθ,y=rsinθ, and z=z. To convert a point from Cartesian coordinates to cylindrical coordinates, use equations r2=x2+y2,tanθ=yx, and z=z.

What is NAD83?

The North American Datum of 1983 (NAD 83) is the horizontal and geometric control datum for the United States, Canada, Mexico, and Central America. NAD 83 was released in 1986. State-by-state adjustments were completed in the 1990s, an effort referred to as the High Accuracy Reference Network (HARN).
