Data and Format Description
Published in Taesam Lee, Vijay P. Singh, Statistical Downscaling for Hydrological and Environmental Applications, 2018
The format of downloaded data is mostly “nc” (i.e., NetCDF format file). This NetCDF format is an open international standard of the Open Geospatial Consortium developed by the University Corporation for Atmospheric Research. The extraction of the NetCDF format is available through various programs, such as C, C++, Fortran, R, Matlab, and Java (http://www.unidata.ucar.edu/software/netcdf/).

netCDF (network Common Data Form) is an interface-oriented format developed for the atmospheric sciences community but widely used in many branches of science. The netCDF library also defines a machine-independent format for representing scientific data.

The time–space cube model is a 3D geographic visualisation technology, and the method can identify the spatiotemporal patterns of data by mapping the data into a cube. A space time cube is created by summarising the data into space–time bins that are stored in the netCDF format. NetCDF (i.e. network common data form) is a file format used to store array-oriented data (Sarah 2017). The geographic location of each bin in the time–space cube is represented by an ID. In the time–space cube model, x and y represent the two-dimensional space, and z represents time. The time–space cubes obtain the longitudinal bin time series through the spatial positioning, and these time series consist of a unit cube (i.e. bar). The data contained in each bar denote the count of geographic event within a unit time step. The structure of time–space cube model is shown in Figure 6. . Each bin has a time-step ID that is shared among all bins within the same time slice.

As described in an earlier section, environmental data in general can be modeled as gridded coverages as well as point vector data. Binding both types to a web environment would require a combination of multiple services since no current service standard represents an overall solution. Common web service standards by the Open Geospatial Consortium (OGC) are for example the Web Map Service (WMS, Open Geospatial Consortium Inc 2006), Web Feature Service (WFS, Open Geospatial Consortium Inc 2010) and Web Coverage Service (WCS, Open Geospatial Consortium Inc 2012). These are implemented by common open source server software like Geoserver or Mapserver. NetCDF is a current standard for working with scientific data. It is, however, not well supported by the previously mentioned implementations. The Geoserver WCS, for instance, cannot return subsets of data in NetCDF while the Mapserver WCS documentation in general recommends to convert NetCDF data to GeoTiff before providing it.
