How To: Convert GCS HARN to Florida State Plane East NAD83

Summary

The following article demonstrates how to convert the projection of a shapefile from GCS HARN to Florida State Plane East NAD83 meters. This example assumes the Input shapefile has an accompanying projection definition file (*.prj).

Procedure

INPUT:
Projection Name: Geographic Coordinate System NAD83 HARN
Units: Decimal Degrees
Datum: HARN

OUTPUT:
Projection Name: NAD_1983_Florida_East
Units: Meters
Projection: Florida State Plane
Datum: NAD83
Zone: East

  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. Since the Coordinate System is known in the 'Step 1' dialog box, the Name tab should be filled in with the correct Input parameters.
