I have one ASCII text file with eight columns. The first four provide the x-coordinates (e.g. longitude) of the four corners of a grid cell, while the last four provide the y-coordinates (e.g. latitude) of the four corners of the same cell in the same order. Furthermore, the fourth x-coordinate of line k is equal to the first x-coordinate of line k + 1, and the third x-coordinate of line k is equal to the second x-coordinate of line k + 1; similarly for the y-coordinates. This means that the cells described in lines k and k + 1 are adjacent having two corners in common. In this context, the number of lines in the file is the number of grid cells.
Is there a way to draw in QGIS the grid cells described in this way?
