Convert Albers HPGN/HARN to GCS HARN

Last Published: April 25, 2020


The following article demonstrates how to convert the projection of a shapefile from Albers HPGN/HARN meters to Geographic Coordinate System HARN.


Base Projection: Albers
Units: Meters
Central Meridian: -84.0
Central Parallel: 24.0
Standard Parallel 1: 24.0
Standard Parallel 2: 31.5
Geographic Coordinate System (Datum): GCS North American 1983 (HARN)
False Northing: 0
False Easting: 400000
Datum: HARN

Projection Name: Geographic Coordinate System NAD83 HARN
Units: Decimal Degrees
Datum: HARN
  1. Load the shapefile and initialize the Projection Utility.

    A. Start ArcView.
    B. Select File > Extensions.
    C. Check 'Projection Utility Wizard' and click OK.
    D. Create a new view and add the shapefile to be projected.
    E. Select File > ArcView Projection Utility.

    The shapefile should be listed in the ArcView Projection utility 'Step 1' dialog box if the shapefile is selected in the Table of Contents. If the Coordinate System field in the 'Step 1' dialog box shows 'Unknown', you need to define the input projection parameters (as shown below). If the content of that field is other than 'unknown', you can skip the input projection parameters definition.
  2. Click Next on the 'Step 1' dialog box. The 'Step 2' dialog box will appear.
  3. Define input projection parameters using the parameters shown above.

    C. Set the Name dropdown list to Custom.
    D. Set the Units for your projection.
    E. Switch to the Parameter tab.
    F. Set the Base Projection.
    G. Set base projection parameters (Central_Meridian, Central_Parallel, and so forth).
    H. Set the Geographic Coordinate System.
    I. Set False Easting and False Northing.
    J. Set the Prime Meridian.
