I have some queries regarding grid. What does this mean. The grid has spatial resolution of 1/2 degrees latitude × 2/3 degrees longitude.?

  • $\begingroup$ thanks alot for replying. i have already seen the link.I want to confirm one thing. The normal world grid has -90 to 90(180 points) lat & -180 to 180(360 points) longitude points. If a grid shows these point with 361 points for latitude & 540 points for longitude. Does this means the grid has resolution of 1/2x 2/3 ? $\endgroup$ – Jahangir Jan 8 '16 at 22:01
  • $\begingroup$ There isn't really any such thing as a "normal world grid". But if the whole world is covered as you describe, and the grid is a lat/lon one, then yes, it's 1/2 * 2/3 degrees. (@fred - you're using 360 degrees for latitude, which is odd :-)) $\endgroup$ – Semidiurnal Simon Jan 9 '16 at 8:42
