It's also interesting on the web too. Try queries like mountain climbing, nuclear testing, steel mill, or drilling for oil and you should see the correlation between the physical locations that match your query.

This example demonstrates our unique ability to easily perform complex text-retrieval and relational database interactions. This GIS application was done in less than 250 lines of Texis Web Script code.

If you are interested in doing something similar yourself then read the "How it Works" below, and also read through the section in the tutorial on geographic searches

How it Works:

We have two Texis tables:

The first has Domain Registration data and distilled Web site content that was obtained with our web-crawler (Webinator) .

The second table has a list of US cities, their longitude, latitude, and population.

1: We search the Web site table for your keywords.

2: The City and State are extracted from each match.

3: Group the answers by matches per city.

4: The Longitude and Latitude of each City is looked up.

5: Create a GIF image of North America and plot red-dots that correspond in size to the number of matches.

6: Create the image hyperlink data so you can click on the dots.
