W7 Protect Critical Infrastructure

The location of the heliport within the three-mile buffer of NORAD along with roads in the area.

The ingress and egress routes within 500 feet of the heliport and the points of intersections of the buffer and the roads

Line-of-sight for points of surveillance around the entrance to NORAD with a 3D graph of one of the LOS

The 3D representation from ArcScene which didn't work out exactly right for me.

The Calculate Area scripting tool provided in the toolbar above will give you the ability to calculate acres and hectares of shapefiles and add the field to the attribute table with the click of one button instead of the many steps required to the old fashioned way of adding each field separately and computing the acres and then repeating the process again for hectares.

Map shows location of aftershocks with a magnitude greater than 3 in relation to the main quake.

 Map shows railroads vulnerable in New Madrid seismic zone X

 Maps shows aftershock magnitudes of any size for a period of about 1 1/2 years in relation to the main quake with intensity

Python Programming

Python is a powerful general purpose programming language developed in 1991 to let you work more quickly by automating tasks.  Its ease of code readability emphasizes it design philosophy and it has a large standard library to work from.  Being able to run on multiple platforms along with it being a a free open source tool greatly enhances its appeal. 
It features a dynamic type system that is checked as a run-time instead of at compile-time.  This speeds up the verification process. As a dynamic language it can be used as a scripting language or as a standalone executable program using third-party tools.
This tool will be very useful in automating task that have to be performed multiple times such as setting up buffer zones around features for analysis.
