| Zusammenfassung |
| SnopViz is a visualization tool for both simulation outputs of the snow-cover model
SNOWPACK and observed snow profiles. It has been designed to fulfil the needs of
operational services (Swiss Avalanche Warning Service, Avalanche Canada) as well as offer
the flexibility required to satisfy the specific needs of researchers. This JavaScript
application runs on any modern browser and does not require an active Internet
connection. The open source code is available for download from models.slf.ch where
examples can also be run. Both the SnopViz library and the SnopViz User Interface will
become a full replacement of the current research visualization tool SN_GUI for
SNOWPACK.
The SnopViz library is a stand-alone application that parses the provided input files, for
example, a single snow profile (CAAML file format) or multiple snow profiles as output by
SNOWPACK (PRO file format). A plugin architecture allows for handling JSON
objects (JavaScript Object Notation) as well and plugins for other file formats may be
added easily. The outputs are provided either as vector graphics (SVG) or JSON
objects.
The SnopViz User Interface (UI) is a browser based stand-alone interface. It runs in every
modern browser, including IE, and allows user interaction with the graphs. SVG, the XML
based standard for vector graphics, was chosen because of its easy interaction with JS and a
good software support (Adobe Illustrator, Inkscape) to manipulate graphs outside SnopViz
for publication purposes.
SnopViz provides new visualization for SNOWPACK timeline output as well as time
series input and output. The actual output format for SNOWPACK timelines was retained
while time series are read from SMET files, a file format used in conjunction with the open
source data handling code MeteoIO. Finally, SnopViz is able to render single snow profiles,
either observed or modelled, that are provided as CAAML-file. This file format
(caaml.org/Schemas/V5.0/Profiles/SnowProfileIACS) is an international standard to
exchange snow profile data. It is supported by the International Association of Cryospheric
Sciences (IACS) and was developed in collaboration with practitioners (Avalanche Canada). |
