Hamstermap.com is a good site for dropping in a formatted set of late longs and
getting as many points on a map as possible. I use it to generate my maps for
the contest.

Looking at the scope of the effort it may not be that hard for a single
contest. In January there were 918 logs and 62,000 exchanges. If one were to
plot the location (6 digit grid) and band capabilities of just those who
submitted logs I think it's a managable manual task.
As a point of reference it took me 2 months of evenings and weekends to plot
the location and send a personal email to every ham on QRZ with an email within
250mi of my station, about 4,000 requesting an FM Q for Sept 2016. Doing just
918 without emails should take less time.
If the .csv file listing preliminary scores is still available then most of the
needed data, call sign and bands would be in a single file so there is no need
to download all the logs. Getting the 6 digit grid would still require going
to QRZ.
Using the logs to capture ALL stations in the logs whether they submitted logs
or not would be a much more arduous task. It calls for some level of
automation, a code to harvest, sort and plot the data which is beyond my
capabilities. Probably a simple task for a good software writer. I will ask a
couple of "my IT guys" at work just how hard/expensive this would be. The
jewel here would be to have the code in hand to repeat the task and update the
map after every contest.
Another useful data set is available from the W3SV and K1RZ database of vhf uhf
stations. This is "crowd sourced", ie people enter their own data and it has
several hundred stations in it. It includes bands, calls and 6 digit grids.
It wont catch the casual contester and may be biased to the east coast, not
sure.
Your thoughts?

Another aspect of what your talking about is something that I have always
thought would be cool to do with all that data would be to compare as much
geophysical data against the log data and plot/observe the logged activity vrs
what was really happening physically and look for trends that might actually
predict the formation of Es, etc. With a database that large the possibilities
are endless.

I have been thinking for a while now about grabbing contest logs for as
far back as I can find and importing them all into a database and then
doing... something with them. Plotting where they were made. Figuring
out which bands are useful in which areas. Seeing how scores change
over time.
I hadn't really decided exactly what I would do, and I've got enough
other projects occupying my time that I haven't gotten around to it.
