Standard Grid System
Topographic 1:30,000 mapsheets are based on the 1:25,000 Printed Topographic Map Series.
In the example below, a standard double-format 1:50,000 mapsheet is shown.
This shows the relationship between 1:30,000 (A4 and A3), 1:25,000 and 1:50,000 mapsheets.

Custom Maps
This allows you to draw a rectangle on the map, which will then be divided into individual sheets.
These sheets can be A4 or A3, portrait or landscape, as you select.
Note - These custom mapsheets are created as pieces of a large (state-wide) map.
Labels, such as road and town names, are not placed to fit within each individual sheet
- so they may be chopped off or not visible.

Magnetic Declination
All mapsheets are created using MGA (Map Grid of Australia) coordinates and are aligned to Grid North.
To convert a bearing calculated from the map to a magnetic bearing (as shown on a compass)
requires a correction for the magnetic declination.
|
Grid Convergence is the value to be subtracted from a Grid Bearing (as measured from the map)
to obtain an azimuth (calculated from True North)
- if Grid North is west of True North grid convergence is positive
- if Grid North is east of True North grid convergence is negative
Magnetic Declination is the angle between True North and Magnetic North
(which is always east of True North in Victoria)
The Grid Magnetic angle is calculated from the magnetic declination and the grid convergence,
and is the angle between Grid North and Magnetic North
- this value must be subtracted from a grid bearing to obtain a magnetic bearing
The magnetic poles move with time, and the Magnetic Variation is the amount the magnetic declination changes each year

To find the magnetic declination values for any point,
use the 
above the index map - which you use to select your maps.
You can download a spreadsheet
or a text file
of values calculated for each 1:25,000 mapsheet.

Pricing and Payment
Standard A4 mapsheets are $2.00 each.
Standard A3 mapsheets are $4.00 each.
Custom A4 mapsheets are $2.50 each.
Custom A3 mapsheets are $5.00 each.
A $1.10 Service fee applies to each order.
This means if you were to purchase 3 x standard A4 mapsheets and 6 x standard A3 mapsheets you would pay:
(3 x 2.00) + (6 x 4.00) + 1.10 = $31.10
All prices quoted are inclusive of GST.
Payment is by credit card (VISA, Mastercard, American Express and Bankcard)
