[SGD02-P12] Development of GNSS analysis result visualization web tool
Keywords:GNSS
Kimura (2018) had developed a web tool for GNSS data for the purpose of volcano monitoring by JMA. This is a tool that draws GNSS data analyzed by JMA on a time-series graph using several methods, and can handle daily coordinate values of the Geospatial Information Authority of Japan in almost the same format. However, this web tool only displays data created in advance by another system, and it was necessary to process the GNSS data first. If it is desired to change the data to be displayed in such a processing form, it is necessary to prepare a plurality of data with slightly different processing. If you want to display the latest analysis data, processing takes time and effort.
We have developed a web tool that is not specialized for volcano monitoring and can easily change the GNSS data displayed by changing the parameters to be read. This is expected to reduce the amount of data to be prepared. Also, if it is desired to display the latest analysis data, only the analyzed data should be prepared. Supported parameters are:
・Removal of offset due to earthquakes, etc.
・Removal of Post-seismic crustal deformation (up to 3 exponential functions and 3 logarithmic functions possible)
・Removal of seasonal change (subtracting seasonal change template)
Of these, for the removal of offsets due to earthquakes, there is a function to create a parameter file for removing offsets while checking the horizontal vector diagram and the time-series diagram of each observation point. The other two are still undeveloped.
Both the map and the time-series chart can be easily enlarged or reduced. This web tool runs on the intra-site of Meteorological College or a web server on your own terminal (for example, linux on wsl2 of Windows, xampp, etc.), and is used for practice classes and student guidance. In this poster presentation, this web tool will be introduced using an actual machine using the daily coordinate values of the Geospatial Information Authority of Japan. For now, only Japanese is supported.
