This step is used to tell RockWorks the coordinate system and units used in the import files for the drillhole locations; if they are different from the project units, RockWorks will translate them to the data coordinates you've defined for your project.
- Current Project Settings: For your reference, the map (X,Y) and elevation (Z) coordinates for the current RockWorks project are displayed here. These cannot be here, they are for your reference only.
- Borehole Data: Use these settings to choose the Coordinate system in which the imported data file locations are recorded.
If you do not know what the import coordinates represent, you should select the same units as your project coordinates, and they'll be imported with no changes. Later, should you need to relabel or reproject the data, you can do so.
- Horizontal Coordinate System Settings: Use these settings to detail your selected coordinate system.
- Lon/Lat: No additional settings need to be made.
- Local: The system origin should equal the project's system origin.
- SPC: Choose the State Plane Zone. If your project is set up to State Plane, that zone will be used.
- UTM: Choose the UTM Datum and Zone. If you project is set up to UTM, that datum and zone will be used.
- Other: Choose this if the imported data are recorded in another coordinate system not listed here. (More info)
- Vertical (Z) Units: Use these to define the units in which the depths and elevations in the imported LogPlot data files are recorded. If the imported data are recorded in different units, the program will automatically convert them during import.
- Multiple Depths by a Constant: Check this box if all of the LogPlot depths in all of the files being imported are to be multiplied by a constant. Enter the value into the prompt.
