I need to calculate the population statistics within a 10 minute drivetime catchment from a point and within 1 Km Buffer from a point in MapInfo, how can I do that can someone please elaborate? I have a population thematic map and I have made a buffer on one location and I need to find the total population living within that area? I am also using a Drivetime addon with MapInfo for drive time catchments and Mapinfo to make Buffers. Many thanks
You should use the Table > Update Column command to calculate the population. Depending on how your population data is stored (point or polygon), how the dialog is filled out will differ:
In the examples:
CatchPopn is the attribute in the drivetime catchments table DTCatch that will receive the calculated population count
PopnCol is the population count attribute in the population source table Population
