Where can I find polygon data of wine (viticulture) areas and their main grape or varietal? I opened the dbf. There are 20,000 polygon areas of vineyards accross Europe--very comprehensive-- but I did not see any attribute information associated with the vineyard areas, just alpha-numeric ids. Any chance you know where the data that links to these alpha-numeric ids might reside? |

How do I figure out if there are clusters of one set of points around another set of points from a different layer? @whuber You're right. After reading your above comment, I have decided my Simple Plot Idea will not provide much information, at least as it was described, so I have removed it so as not to confuse people. I now believe Joint Count Statistic is the simplest method to approach the problem. |

Spatial statistics tools : clustering analysis on raster data A measure of artificial light would be a good proxy for urban conditions. A google search should find example studies. |

How do I figure out if there are clusters of one set of points around another set of points from a different layer? @whuber 1st thanks for the explanation of the problem of Ripley's K function. 2nd, when we see a plot of stock prices over time, we can look for general trends up or down or random, also we can pick-out times that there were large decreases or increases and ask why. A plot of how the concentration of buildings changes as distance changes can be used in the same manner. It can be used to search for spikes in concentration, which is evidence against a random distribution, also it can be used to focus further investigation of curious spikes. |
