Useful links
Here I provide a list of links to web pages and programs that I use on a regular basis, or occasionally just for something a little different...
All links open in a new window.
GPS
- Scripps Orbital and Permanent Array Center ("SOPAC") is useful for many things GPS but below are some utilities I find particularly useful:
- Date converter between calendar date (e.g. YYYY MM DD), ordinal date (YYYY DoY), decimal year (YYYY.0), GPS week (WWWW D) and Modified Julian Day (MMMMM)
- Site ID checker (against SOPAC's database, so not perfect) for when you're installing and naming new sites
- Antenna calibration from the National Geodetic Survey (most useful for their collection of antenna specification diagrams, I find)
- UNAVCO Data Archive Interface (for searching the UNAVCO archives and generally a good place to gather information on publicly available sites in any given area)
- Raw and RINEX conversion utilities:
- Trimble's runpkr00 raw conversion utility (now maintained by UNAVCO)
- teqc
- Ashtech RINEX Converter (Windows executable)
- Trimble Convert to RINEX (Windows self-extracting installer)
- Trimble DAT to RINEX (Windows executable)
InSAR
- Matt Pritchard's (Cornell University) ROI_PAC web page has many hints and further links on the ROI_PAC software.
- Rob Mellors' (now at Lawrence Livermore National Laboratory) provides information and programs on pre-processing of ALOS data.
Geology
- The International Commission on Stratigraphy's International Stratigraphic Chart
- The Geological Society of America Geologic Time Scale (Walker, J.D., and Geissman, J.W., compilers, 2009, Geologic Time Scale: Geological Society of America, doi:10.1130/2009.CTS004R2C)
Weather
