Header file format is:id The identification string DSAA that identifies the file as an ASCII grid file.nx nynx is the integer number of grid lines along the X axis (columns)ny is the integer number of grid lines along the Y axis (rows)xlo xhi xlo is the minimum X value of the gridxhi is the maximum X value of the gridylo yhi ylo is the minimum Y value of the gridyhi is the maximum Y value of the gridzlo zhi zlo is the minimum Z value of the gridzhi is the maximum Z value of the gridgrid row 1grid row 2grid row 3 -these are the rows of Z values of the grid, organized in row order. Each row has a constant Y coordinate. Grid row 1 corresponds to ylo and the last grid row corresponds to yhi. Within each row, the Z values are arranged from xlo to xhi. Blanked grid nodes are given a Z value of 1.070141E+038. Rows are 39.855 m apart, Columns are 40 m apart.dem_11.xlsExcel file with all points used to calculate the dem_2003.xls grid (refer to A2).The folder also contains high resolution jpeg images of Fig. 16 and the data distribution figure (A2).Lagoon bathymetry folderFolder containing Excel files with Easting, Northing (acquired using Garmin GPS V; WGS84, UTM zone 43) and depth (acquired using Garmin 'Fishfinder' depth sounder) for each lagoon surveyed.
