It is pretty slick, but I just started using it about an hour ago, so I haven't thought much about what to do with it. I did see a comment where someone from Google said that reverse geocoding is not possible yet.
I am going to have to get up to speed with PostGIS, but this is a pretty simple operation. I didn't number the addresses, but each event has a real address and a "cleaned" address column in a table. The CSV that I uploaded to Fusion was just a "select distinct..." of the cleaned addresses, so it will serve as a lookup table for all the addresses in the original table. I'm not sure how I am going to reorganize the tables afterward, but I want to interpolate temperatures for each data point based on other data that I have, and I think PostGIS only does simpler operations right now, so I might have to export the points into shapefiles for each day an event occurs and do splines in another package, then copy the interpolated values back into the database. I am sure there is a more elegant way to do that, I really need to think about it some more. (Oh, hey, I just saw that you can compile R into Postgres. That is pretty crazy, but potentially totally awesome: http://postgis.refractions.net/pipermail/postgis-users/2009-March/022894.html ) Cheers, JP On Sat, Feb 5, 2011 at 12:17 AM, Dan Putler <[email protected]>wrote: > Glad to be of help, I'm just curious about what the licensing / terms of > use on the KML files that come out of fusion tables.
