Converting Rw3D Coordinates

RockPlot3D | Utilities | Convert Coordinates

This program is used to convert the coordinates in an existing Rw3D scene from one coordinate system to another.

Related Topics:

• Setting the View Dimensons, Coordinates/Units, and Vertical Exaggeration for information about assigning the coordinates and units in an existing Rw3D scene.
• Reprojecting project coordinates for information about converting the coordinates in the database.

Menu Options

• XY Units:
  • UTM Coordinates: Select this to reproject the scene's X,Y coordinates to a Universal Transverse Mercator system.
    • Datum: Click to the right to view the available projections.  The two most common projections for the U.S. are:
      • Clark 1866 (NAD-27): Used within most USGS maps. NAD-27 coordinates may be as much as 200 meters from WGS-84 (NAD-83) datum of the exact same coordinate.
      • WGS-84 (NAD-83): Used by GPS (Global Positioning System) units and more recent USGS maps.
    • Zone: Click on the button to the right to display an interactive map where you can click on the UTM Zone for the data.
    • Units: Choose whether the UTM coordinates are to be represented in Feet or Meters.
      
      
  • State Plane Coordinates: Choose this to reproject your scene's X,Y coordinates to the US State-Plane system.
    • Zone: The State Plane systems are zone-specific, so you need to define the zone to which the coordinates apply. Click to the right to select the zone from the drop-down list.
    • Units: Choose whether the State Plane coordinates are to be represented in Feet or Meters.
      
      
  • Local: Choose this to reproject your scene's X,Y coordinates to a local coordinate system. RockWorks will assume a Cartesian coordinate system whereby X coordinates increase in value to the east, and Y coordinates increase to the north.
    • Units: Specify whether the Local coordinates are to be represented in Feet or Meters.
    • Reference Point: You can geo-reference your local coordinate system by entering the longitude and latitude coordinates in decimal degrees that exist at the local coordinate "origin" of 0,0. Note that western longitudes and southern latitudes are negative.
      If you don't know these global reference coordinates, you can leave the Local Origin set to a Longitude of 0.00000 and a Latitude of 0.00000.
      
      
• Elevation Units: Choose Feet or Meters for the reprojected scene.
  
  

Step-by-Step Summary

1. If necessary, open the RockPlot3D scene to be converted or click in the current RockPlot3D window containing that scene. 
2. You can double-check the scene's current coordinate system by selecting the View | Dimensions menu option and clicking on the Units tab.
3. Select the RockPlot3D Utilities | Convert Coordinates menu command. 
4. Enter the requested menu options, described above.
5. Click the Process button to proceed.

The program will translate the coordinates of all of the entities within the scene from the existing coordinate system to the new system. The reprojected scene will be displayed in a new plot window.
