  1. This error can occasionally occur if you are using a newer license file with an older version of the program. Try downloading the latest version of your software and reinstalling.
  2. Rockworks2004 will honor the "Regional Settings" that you have established in the Windows Control Panel, specifically the way that real numbers are entered. While "," is the digit grouping symbol and "." is the decimal symbol used in the U.S., this is not the case for other regions where the symbols may be reversed. When RockWorks is first started on anycomputer, it will look at the number formatting established in Windows, translate the tutorial data files and system library files into that number format, and write them to the My Documents\RockWorks2004\Samples and System folders. As long as your own data is also entered using the indicated numbering format, RockWorks should work fine. It will be able to read the numbers correctly as well as use the appropriate characters in contour and point labels, in legends and computations, and so on. Important note: If you CHANGE the number formatting after you've worked inside RockWorks, you will need to reset the program's defaults prior to running RockWorks again. The easiest way to do this is to rename the existing "My Documents\RockWorks2004" folder to another name, such as "My Documents\RockWorks2004_old", and restart RockWorks. It will think it's a new installation and will rebuild the sample files and system libraries for the new numbering system.
  3. RockWorks offers point and line digitizing into the Geological Utlities datasheet, interfacing with an external digitizing tablet. RockWorks does not provide stream digitizing in order to prevent huge amounts of data from being captured. With stream digitizing, points are entered at a constant rate whether the puck has moved 10 inches or 1/2". This can lead to a large amount of data that has to be processed by the program. By contrast, with point digitizing you can place as many points as you need to accurately trace a line, capturing more points for sharp inflections and fewer points where the line is relatively straight. RockWare offers other programs for tablet and screen digitizing which generate data that can be imported into RockWorks. You can search for "digitizing" on the RockWare home page for a listing of the current products.
  4. You can import data from Excel into both the Borehole Manager and Geological Utilities windows in RockWorks. For the Borehole Manager, you must be sure to set up the Excel worksheets EXACTLY as documented in the RockWorks help messages. (There is an Excel template, with all possible worksheets, on RockWare's main support page. You can use this to lay out the data in Excel.) To import the data, use the File / Import / Into Borehole Manager / XLS (Excel). There are some options regarding borehole file replacement/renaming, etc. It's important to note that this process does not append data to existing borehole files, it creates entire borehole files with the full complement of Excel data. If you need to append data from Excel onto existing borehole files, you must first export the borehole data to Excel, add the new data, and then re-import. For the Geological Utilities, a single Excel worksheet can be imported. Use the File / Import / Into Geological Utilities / XLS (Excel).
  5. The RockWorks Grid > Import tool can be used to import USGS 30-meter, USGS 3 arc-second, or Canadian Government Digital Elevation Models (DEM's) directly. However, the newer USGS "SDTS" format is not supported. If you wish to import DEM's that are stored in an SDTS format, RockWare sells a really cool program called "Global Mapper" that will read such files, display them on the screen, even panel multiple quadrangles, and then export them directly to a RockWorks grid file format. See http://www.rockware.com/catalog/pages/globalmapper.html for details.
  6. At the time of this writing, the USGS web site offers a number of different aeromagnetic and gravity data sets for free download. (Go to www.usgs.gov and click the link for "geophysical products".) We recommend downloading the zipped "gxf" format grid models. After downloading, unzip the grid model, and then use the RockWorks Grid menu's Import command to import the Geosoft GXF model, saving it as a RockWorks "GRD" format. You can create either 2D or 3D maps of the geophysical measurements. If you wish to analyze multiple geophysical models of your study area to determine those areas where all parameters are favorable, use the Grid > Filters > Boolean tool to create Boolean (true/false) grids of each model, and then use the Grid > Math > Grid & Grid Math tool to multiply the Boolean grid models. (This requires that the models have the same number of nodes along the X and Y axes.) Those areas not zeroed-out meet your criteria for all of the data.
