v3 v4 8 8 In case of mixed rectilinear/curvilinear geometries, a non-standard so-called `ReferenceableGridByArrayAndVectors` type ![1] will be used, for a more compact and convenient GML description. 9 9 10 Finally, we will assume that all the time series will be referenced by the daily-resolution (UoM=days ['''d''']) [http://kahlua.eecs.jacobs-university.de:8080/def/crs/OGC/0.1/ANSI-Date ANSI-Date] CRS along the temporal dimension, which (by default) has a '''`t`''' positive-onwards axis. 10 Finally, we will assume that all the time series will be referenced by the daily-resolution (UoM=days ['''d''']) [http://kahlua.eecs.jacobs-university.de:8080/def/crs/OGC/0.1/ANSI-Date ANSI-Date] CRS along the temporal dimension, which (by default) has a '''`t`''' positive-onwards axis. 11 12 NB. The axes labels expressed in the geometric domain of a coverage are the labels of the '''coverage''' axes, which here will be labelled as increasing numbers `(0, 1, 2, ...)`, by default. Indeed, they are independent from the axes labels of its '''CRS''', which are instead used in the WCS ''!GetCoverage'' requests. 11 13 12 14 '''Abbreviations:''' 13 15 * '''`GML`''' : Geographic Markup Language 14 16 * '''`CRS`''' : Coordinate Reference System 17 * '''`SO`''' : Single object 15 18 * '''`RTS`''' : Regular Time Series 16 19 * '''`ITS`''' : Irregular Time Series … … 28 31 [[span(In the 1D case, it is also clear how the gridded coverages can cover datasets which are not usually associated with the concept of ''grids'' (e.g. trajectories), style=color: Black; font-size: 80%)]] 29 32 30 || '''ID''' || '''DIM''' || '''Description''' || '''Single object''' || '''RTS''' || '''ITS''' || '''MRTS''' || '''MITS''' || 31 || [#a1:1Dtemporalseriesofaspatialdata 1] || 1D || Temporal series of data with no spatial reference || [#a1 link ] || [#a1-RTS link ] || [#a1-ITS link ] || --- || --- || 32 || [#a2:1Dspatialobservationsonastraightline 2] || 1D || Point measurements (''with'' spatial reference) on a straight line || 33 |||| [#a2a:...alongastraightline,paralleltoaCRSaxis 2a] || ... parallel to a CRS axis (2D space) || [#a2a link ] || [#a2a-RTS link ] || [#a2a-ITS link ] || [#a2a-MRTS link ] || [#a2a-MITS link ] || 34 |||| [#a2b:...alongastraightdiagonalline,notparalleltoaCRSaxis 2b] || ... diagonal wrt CRS axes (in 2D space) || [#a2b link ] || [#a2b-RTS link ] || [#a2b-ITS link ] || [#a2b-MRTS link ] || [#a2b-MITS link ] || 35 |||| [#2c:...alongastraightdiagonallineinthe3Dspace 2c] || ... diagonal wrt CRS axes (in 3D space) || [#a2c link ] || [#a2c-RTS link ] || [#a2c-ITS link ] || [#a2c-MRTS link ] || [#a2c-MITS link ] || 33 || '''d''' || || '''Description''' || '''Dim''' || '''SO''' || '''RTS''' || '''ITS''' || '''MRTS''' || '''MITS''' || 34 || [#Case1 1] || || Temporal series of data with no spatial reference || 1D || [#a1-SO link ] || [#a1-RTS link ] || [#a1-ITS link ] || --- || --- || 35 || [#Case2 2] || || Point measurements (''with'' spatial reference) on a straight line || 1D || 36 |||| [#Case2a 2a] || ... parallel to a CRS axis (2D space) || " || [#a2a-SO link ] || [#a2a-RTS link ] || [#a2a-ITS link ] || [#a2a-MRTS link ] || [#a2a-MITS link ] || 37 |||| [#Case2b 2b] || ... diagonal wrt CRS axes (in 2D space) || " || [#a2b-SO link ] || [#a2b-RTS link ] || [#a2b-ITS link ] || [#a2b-MRTS link ] || [#a2b-MITS link ] || 38 |||| [#Case2c 2c] || ... diagonal wrt CRS axes (in 3D space) || " || [#a2c-SO link ] || [#a2c-RTS link ] || [#a2c-ITS link ] || [#a2c-MRTS link ] || [#a2c-MITS link ] || 39 |||| [#Case2d 2d] || ... diagonal in 3D space with irregular spacing || " || [#a2d-SO link ] || [#a2d-RTS link ] || [#a2d-ITS link ] || [#a2d-MRTS link ] || [#a2d-MITS link ] || 36 40 37 41 == Examples == 38 42 39 === __1__ : 1D temporal series of aspatial data === 40 41 This section covers time series of point observations with no spatial reference (or where the spatial reference was not considered relevant): in this case the only distinction is whether there is a regular time step between observations, or not.
