[IDV #GCJ-735707]: csv time data files of GPS position time series

Hi Stu,

> Description of problem: Here is part of a csv file from UNAVCO for the 
> position time series at one GPS station. The position values show crustal 
> deformation with time.
> 
> Can this format be read by the IDV directly? If not, can a simple header be 
> made that will allow the IDV to understand the file? The goal is to show 
> three time series plots of "North,East and Vertical" at a station in the 
> popup box when the station is clicked in the map display. Each station has 
> about 1000 lines (times).
> 
> The data is online at http://pboweb.unavco.org/?pageid=88 as "Position Time 
> Series."
> 
> PBO Station Position Time Series

With some modifications the IDV can read this. The point csv format is 
described here:
http://www.unidata.ucar.edu/software/idv/docs/userguide/data/TextPointData.html
First, the non data lines should removed or commented out. Then, you need the 2 
header lines as described in the above doc.

For the lat/lon you don't need them on every line. Look in the section "Fixed 
values for several observations" for a way to define them once.
