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 grid
xhi is the maximum X value of the grid
ylo yhi ylo is the minimum Y value of the grid
yhi is the maximum Y value of the grid
zlo zhi zlo is the minimum Z value of the grid
zhi is the maximum Z value of the grid
grid row 1
grid row 2
grid 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.
