| Good day.I am working with the SQLGeography class and objects to do some work with distance. The area where I am coming up a bit short of finding a clearly defined example of the methods need to achieve finding the bounding box from a lat/lon point.As an example I have a give coordinate point (1,1) and want to find the Max/Min Lat & Lon 50 miles away.I would then use these two points to find all records that fall within this box (circle). I have 8,100 locations in which to do this and the 250 million candidate records this will help get the dataset into a manageable size before calculating the actual distance.We have our own functions that we use now but I would like to try an leverage the SQL Server functionality because from what I am reading it seems to be more accurate in.Thanks.
