Mappers, I'm attempting to write a program that produces three circular buffers around a point (a water well), BUT the buffers need to be offset a certain number of feet in a certain direction. The distance and direction of offset need to be calculated from data input by the user. If I were using a coordinate system whose unit of measurement was feet I could just query the centroid of the water well, do the math, and create a new dummy point surrounded by a buffer at the correct offset. My problem is that the tables I'm working with are in Lat/Long NAD27. I'm assuming that if I query a point object in this case, the centroid will be returned as a Lat/Long value, which isn't much use in calculating offset distances. Is there some way to use the Set Coordsys command so that my location and distance calculations will work in feet rather than degrees? TIA and will sum. _____________________________ Tim Warman Geologist & GIS Specialist Richard C.
