Maps stacks are time series of grid data Three data formats are supported: - usgs bil, bip - pcraster native format - ascii format In the usgs format all timeSteps are in a single file. In the other two formats each time step is stored in a separate file. The order of the maps is determined by the file extension and the last two characters of the first part of the filename: (e.g. evap0000.001, evap0000.002 …. evap0000.999, evap0001.000). This limits the size of a stack of maps to 9999999. Maps stacks are time series of grid data Three data formats are supported: - usgs bil, bip - pcraster native format - ascii format In the usgs format all timeSteps are in a single file. In the other two formats each time step is stored in a separate file. In this case it is required to indicate the position of the file number by a ??? pattern. Only one pattern may exists. The number of question marks in the pattern is user defined. e.g. pattern is evap.??? results to evap.001 …. evap.999 e.g. pattern is evap????.asc results to evap0001.asc …. evap9999.asc If non equidistant map stacks are used the date time elements are required date/time of the first event date/time of the last event Link to one of the three supported file formats. For each file another file with the positions of the cell centre points most be present. See cells.xsd Date and time of each event in the stack. This is needed for non equidistant data. The number of event elements MUST match the number of maps/profile etc use this field as a notebook to add comments, suggestions description of data entered etc. Link to one of the three supported file formats. For each file another file with the positions of the cell centre points most be present. See cells.xsd eg: temp????.??? See map stack description eg: temp????.??? See map stack description Required file with xyz co-ordinates(lat-long) for each centre-point of the grid. the format of the file is described in cells.xsd
