Amplified Directions: you must enter your Latitude-Longitude pair in only one of the four options listed. When you have done so, click your mouse on "Find C.A.P. Grids."
You can get the Latitude-Longitude pair from any source, but GridFinder is designed around SARSAT hits.
Option 1: You must enter the Latitude and Longitude in WHOLE Degrees and Minutes with decimal minutes. Example: 44 in the degrees (º) block, then 59.34 in the Minutes (') North (N) block. LONGITUDE is entered in the same way. Example: 092º 44.82' West (W).
Option 2: In this option you enter the Latitude and Longitude in Degrees with decimals (DEGREES.deg). Example: 44.989º N Longitude 92.747º
Option 3: If you choose this format you must enter Latitude and Longitude in whole Degrees, whole Minutes, and Seconds with a decimal afterwords (if desired or needed). Example: Latitude 44º, 59' (whole minutes) 20.4'' (decimal seconds) N and Longitude 092º 44' 49.2''W.
Option 4: This is similar to option 2, except instead of using West Longitude we use a minus sign-to the left, or West, of the Prime Meridian (0º Longitude) being negative. For the Western Hemisphere, the area of the Earth that GridFinder covers, simply take the West Longitude and add a minus sign to get the equivalent. In any case, enter the Latitude and Negative Longitude in Degrees with decimals. Example: 44.989º N Longitude -92.747º
All Options: With this small menu you can determine which things you want to include or eliminate from your final output box, in other words, your OPTIONAL OUTPUT. If the square next to "Maps" has a check in it (which is the default) you will view four maps of increasingly larger scale for the point you select. This option requires a connection to the internet to function properly. The next check box is for the simplified Grid Diagram. This option will output a simplified grid chart of the entire Sectional with the grid that contains your point being highlighted in red. This feature is optional because in older web browsers such as Microsoft Internet Explorer 3.0, it might take a minute or so to display the diagram. The last check box option is "No Extras & Offline." You can check this if you don't want to see any of the internet links, maps, or even the grid diagram. Note, however, that even if your computer is NOT connected to the internet when your links are generated by GridFinder, you can connect to the internet at a later time and click on the link to navigate to that desired feature.
Feel free to play around with GridFinder. You really can't hurt anything!
PLEASE SEND IN YOUR SUGGESTIONS!
efforts are underway to resolve these problems but you can avoid them with knowledge.
Currently Alaska grids are not supported by GridFinder™. The coordinate conversion to UTM and MGRS work correctly, as doCell, GARS, and USNG grid location. This is a high-priority fix and will be addressed as soon as possible.
GridFinder works best when you don't try to fool it. That is, if you enter points outside of the continental United States you won't get complete results. If the information that you enter is incomplete you may be required to reenter it. You should not mix coordinate data types; you may get an erroneous result with no error indication.
There are two requirements to run GridFinder. If you don't meet either one you should see a message similar to the two requirements below on your screen on the data entry page.
