Converting Rw2D Map Coordinates

RockPlot2D | Utilities | Convert Map Coordinates

This program is used to convert map coordinates in an existing Rw2D file from one coordinate system to another.

Setting the Diagram Type, Units, and Projection for information about assigning diagram coordinates and units to an existing Rw2D file.
Reprojecting project coordinates for information about converting the coordinates in the database.

XY Units:
- Lon/Lat: Choose this to reproject your map to a decimal longitude and latitude coordinate system. (WGS 84)
- Local: Choose this to reproject your map 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.
- State Plane Coordinates: Choose this to reproject your map 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.
- UTM Coordinates: Select this to reproject the map coordinates to a Universal Transverse Mercator system. (WGS 84)
  - Datum: Click to the right to view the available projections.
  - 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.
- Other: Click in this radio button if you want to choose from an expanded list of projections. (More info)

If necessary, open the map to be converted (see Opening Plot Files) or click in the current RockPlot2D window containing that map.
You can determine the map's current coordinate system by right-clicking anywhere in the map, and selecting the Projection option from the pop-up menu.
Select the RockPlot2D Utilities | Convert Map Coordinates menu command.
Enter the requested menu options, described above.
Click the Process button to proceed.

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