When I use the concentric buffer tool that is packaged
with MI 5.5 I get all kinds of errors I never heard of and are not documented.
One I get is "too many open files" (3 are open) , I have .5 gig RAM , when
I try to use the statistics part. Another error is "Cannot include datatype
clause if updating existing column" and others. Also the feature to set the
appearance of the buffers( color, fill pattern) doesn't work. Generally it
appears that the concentric ring buffer tool is not all that good. Would anyone
have another one?
I need to be able to make concentric rings around a point or
polygon and then estimate the covariates on the buffers from data underneath,
sum for sure, average and weighted average and count as well - like population
from overlaying buffers over census tract data, etc.
Thanks a lot
