I have a road network as a table and another table which has a series of regions - a bit like a set of concentric circles which form donut regions, with each region not over lapping. what I need to do is calculate the length of roads within each donut region. I have several tables of historic road network (e.g. 1950 network, 1960 network 1970...) and would need to the same calculations for each historic road network table.
I do not have MapBasic, is this something I can do easily in MapInfo through queries?
