RockWorks requires that you define coordinate systems and units for any spatial data (map X and Y coordinates) listed in the Utilities datasheet. This is a 2-step process:
- Specifying the coordinate system and units for the columns.
- Specifying the coordinate system details in the metadata section of the file.
Step-by-Step Summary
- Open the datasheet you wish to edit, or create a new datasheet.
- Define the coordinate system and units for the columns:
- Click the Columns | Column Properties menu option to access the Column Properties window. (You can also right-click in the datasheet and select Column Properties.)
- Set up the column titles and units. Use the green arrows to access previous/next columns. See Changing Column Titles, Styles, and Units for details.
- Click OK to close the column properties window.
- Define the coordinate system details.
- Access the Additional File Information pane to the right of the datasheet. If it is not visible, click the small "+" button in the upper-right corner of the data window. (See the green arrow in the picture, above.)
- Define the projection information. (See Coordinate Systems for more details.)
- For UTM coordinates, you'll need to define the Datum and the Zone.
- For State Plane coordinates, you'll need to define the Zone.
- For Local coordiantes, you'll need to define the reference longitude and latitude, if known. (If not known, just set these to 0 and 0.)
