I have a table of strike and dip symbols in MapInfo. I need to export these to ArcView but ArcView starts the symbol at a different angle and rotates in the opposite direction that MapInfo does. (ArcView starts at horizontal 0 degrees and rotates counterclockwise while MapInfo starts at vertical 90 degrees and rotates clockwise.) I figured out the formula to transform the coordinates and had to do it by quadrant, which means I had to query and update in 4 separate segments. My question is this, is there a way to do this in one mass update?
Here are the formulas that I used to get the correct ArcView strike angle Strike Formula 0-90 180 + (90 - Strike) 91-180 90 + (180 - Strike) 181-270 (270 - Strike) 271-360 270 + (360 - Strike) Willie Wangberg Information Tech Rio Tinto Exploration 52 Glen Carran Circle Sparks, NV 89431 P: (775) 358-9500 F: (775) 358-9529 email: [EMAIL PROTECTED] --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 12025
