Here's a little QGIS python function that implements this. It requires the rasterlang plugin (the repository has to be added to QGIS manually). It expects three mandatory parameters: The points layer, a raster layer (to determine the size and resolution of the output), and a filename for the output layer. You can also provide an optional argument to ...

I envision a "Farmland Suitablility Database" that can analyze land suitablility conditions for various crops and make crop yield projections. Information from the database could be used to help assess the risk of an investment, or for marketing financial instruments among land owners with the right stuff.

As scw says in his comment the code itself seems to make use of some basic processing and loops so could probably be rewritten quite quickly in Python and Shapely. However if you are looking for a script take a look at the following written in R..and German: http://www.reymann.eu/wp-content/uploads/2010/06/GravitationsgesetzHuff.R Google Translate seems ...

Some reasons that came into my mind: -Check for frauds related to land size, crop extents, etc. -Analise the extents of the damage in case of an insurance claim. -Be able to retrieve fast data to build prognostics make future planning and make and answer questions like: "how much area is in this tornado danger zone?" "What is the expected crop losses if ...

If you are in an academic institution ESRI Business Analyst is very affordable. It costs approximately $3000, but it has full US coverage based on the Dunn & Bradstreet data, and is geocoded. It is also available for specific years. The downside is that the licensing is ridiculously complicated and restrictive (so much so that despite having the money ...

Demographics are probably the most important of your data sets in geomarketing. If you are planning on using the US Census/ACS (American Community Survey) be sure to research the proper methodology for using the rolling average that is the ACS. We no longer have a true snapshot now that the census long form is gone. Additionally, there are demographic data ...

Based upon your description, I would suggest the opposite method that @artwork described. Use the same tools, but start with your block groups as your primary layer and join the customers to the polygons with a spatial join, which will give you a count field. From the Layer dialog, Right-click on the polygon layer, choose Joins & Relates->Join and ...

You may want to split your large block group data set into seperate feature classes within a file geodatabase for processing. After doing that you can run a spatial join from the ArcMap TOC. Right click the customer locations layer and select Joins and Relates>Join. On the top drop down select "Join data from another layer based on spatial location". ...

See http://www.spatialecology.com/htools/overview.php for an excellent free toolset called Hawth's Tools, which performs a raft of useful functions, including counting the number of points in each polygon (see > Analysis Tools > Points In Polygons). Once you have this value you could use the Field Calculator to calculate the percentage of the total points.

My personal experience is that 99% of the GIS projects I do involve some form of calculation. I can't remember ever having "simply put points on a map", though I'm sure I must have, even if only as a training exercise when learning a new GIS. Expanding this to a biased back-of-an-envelope survey to include all the GIS practitioners I know and have worked ...

I would like to suggest you to post this question as a discussion in LinkedIn as well. Some groups like GIS, Mapping, and Geo Technology Professionals and GIS Group have experts from various domains which would enable you to get more valuable answers. I have seen few discussions spanning several months.

In doing some additional research for sources in my state (Oregon) and found that the Secretary of State Corporation Division sells an extract for $500. I figure this is just one possible source that resides out there somewhere and there are more than likely other similar options from various government organizations. Update: This article talks about likely ...
