Disussion Forum added to help everyone with their visualization work

Also check out the new Lawrence, KS wireless network Distribution Study

Procedure
Graphical representation of a point data file produced by Netstumbler of a single wireless network.
High-resolution black and white aerial photography of the same area.
Point file and image file are put into the same map projection/ coordinate system and layered on top of one another in a Geographic Information System (GIS).
Signal strength values, collected for every point by Netstumbler, are used to indicate the relative strength of each data point.
Blue = strong and
Orange = weak.
Using the Inverse Distance Weighted (IDW) interpolation technique, values are generated between the existing point data to recreate what that signal strength should be for the entire network.

The final map shows a visual representation of the field of signal strength emitted by a wireless network device. The gradient from dark blue to orange represents both strong to weak signal reception and high to low network speed.
Coming Soon: Discussion Forum to get everyone aquanted with
the proecess in greater detail
