How does this work?

Just wondering if someone could advise how to enter co ordinates correctly into the following grids? I must admit I struggle a bit with the varying formats and can never remember which is which, and the NW/SE bit has me completely confused. I'm sure I suffer from dyscalcula.

No matter which combination I try it comes back with what I assume is an error message.





The grids above are off the Landgate website. For those that arent aware, their images of WA are generally far superior to Google Earth and Nearmaps (outside of metro areas).

The first one is like 34 degrees 38 seconds 12 minutes.

The second one would be like 34.5346 degrees.

NW will be a point at the north-western corner of a square/rectangle and SW will the be south-eastern corner of the square/rectangle. The result will give you a shape that has the points as the NW and SE corners. You also need to make sure you are using the same datum as the mapping system (probably WGS84).

Hope this helps.

Makes sense now, instead of being able to enter a specific point you have to select an area you want to look at. I wonder how long it would have taken me to work that out. :?
