MapGrids

MapGrids is a program for converting between the Mapping Grids used in Australia, including AMG, MGA & WGS.

MapGrids may be used just for converting data for WGS84 - converting between Lats, Longs & Eastings & Nothings.

(Microsoft Windows version only)

The program performs immediate conversions between Latitude / Longitude and UTM - Zone, Easting & Northing
It converts between Decimal Degrees and Degrees, Minutes & Seconds
It converts between Australian Mapping Grid 66 (AMG / AMG66 / AGD66) and Map Grid of Australia 1994 (MGA / MGA94 / GDA94)
The Geocentric Datum of Australia (GDA94) is equivalent to commonly used World Grid System 84 (WGS84)
MapGrids is Microsoft Windows based
MapGrids Converter Program is freeware

Using Mapgrids

Just download the Zip file and extract the executable to a folder.
Run the program.
As you begin entering data and move from field to field the conversion will be performed
and the other fields will be filled with data. E.g. If you entering data for Lats and Longs for
AMG data the conversion is automatically done to UTM (Eastings and Northings) for AMG, and also to Lats & Longs / Eastings
& Northings for WGS84.
So from what ever mapping system you start with, conversion is done to the others systems automatically.

Remember to enter Australian Latitudes as negative values.

A printed report is produced by clicking the Print button. The Report title is taken from the text in Site Title field,
so that you can label and keep individual conversions as required.

If required, selecting the Stay On Top box, will keep MapGrids on top of any other programs you are using. Useful if you
converting lots of data, and switching between two programs.

FAQ

Question 1. Why only AMG and WGS84?
Answer: The need for this program came from dealing with various paper maps where I work. And also applications and database systems
that used the multitude of grid systems as references. From what I researched AMG66 is used by most of our older maps and systems,
and WGS84 was now the world standard as far as GPS systems go. The newer GDA closely corresponds to the WGS84 system.

Question 2. Why didn't program calculate the correct values?
Answer: Remember to enter Latitude values for south of the Equator as negative.

Online Version is available here
     Only converts AMG Lat / Longs to UTM Zone, Eastings, Northings.
     Experimental and under development but the current conversions are accurate.

Mobile versions
July 2009 - I am considering creating a mobile version of the Mapgrids program, Probably initially for the Apple iPhone and
then maybe for the Nokia mobile, if possible. If you have any suggestions or specific requirments let me know using the feedback form.
