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 > Format Version,1.0.1 > 4-character ID,ELKO > Station name,ELKO_BRGN_NV1997 > Begin Date,2004-01-07 > End Date,2008-07-28 > Release Date,2008-07-30 > Reference position,40.9146904918 North Latitude,-115.8171979278 East > Longitude,2016.89028 meters elevation, > Date,North (mm),East (mm),Vertical (mm),North Std.

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. -Jeff Ticket Details =================== Ticket ID: GCJ-735707 Department: Support IDV Priority: Normal Status: Closed
