This application can check the contents of WIN and WIN32 format file and display waveform data. Basic usage of this application is just to choose WIN and WIN32 files using a select button. Then, waveform data is displayed in the panel within the browser. Duration and displayed stations can be selected and changed at the details field within the browsing window. If a channel table file is specified, information of station, component, and physical amplitude is reflected in the panel.
WIN system contains some programs to handle the content of a WIN file. “wck” in the WIN system is a tool to check the content of channels. “dewin” in the WIN system is a tool to decode the seismic data of a specified channel from a WIN format file. This web application has similar functions to these two programs, when these operations are specified within the details field. I note that organization ID and network ID information are displayed for WIN32 files. This is a newly added feature to the original “wck” program.
This application is, however, sometimes slow in the case of handling large files which is larger than several tens of megabytes. Memory usage should be improved in the future. In addition, appearance should be also refined for better user experiences.
