Search of historic map collection of Queensland by coordinates

The Qld Govt has digitised over 10,000 historic maps of Queensland. One of them may be perfect for your historical research, but you aren’t going to look through 10,000 maps to see if they cover the place you want.

This tool allows you to specify where in Queensland you are interested in using latitude and longitude and it will return you a list of maps that include that place. Depending on the information provided with each map, we either know exactly if it includes the place (works for about 2/3rd of the maps) or we have to do some guesswork (about 1/3rd of the maps). If the map suggested was based on guesswork, it will be indicated in the Approx field.

The maps are always returned to you ordered by scale, so the most “close-up” map covering a small area will be returned before the “broad brush” maps covering a large area. Generally close-up maps will show more detail. But different types of maps show different kinds of information, so you should check the less detailed maps if the detailed maps don’t help.

Please enter the latitude and longitude of the place of interest in decimal format. Latitudes for Queensland are negative (South) and Longitudes positive (East).

How to get latitude and longitude in decimal degrees using Google Maps.

Navigate your way to your place of interest on Google Maps. Then right-click and choose “What’s here”. A small pop-up will appear with the decimal degrees displayed. To copy the decimal degrees, click on them and then in the panel on the left of screen, it will display the location you choose in both degrees/minutes/seconds (in a larger font) and decimal degrees immediately below (in a smaller font). Copy the decimal degrees from the left panel.

If you already have your latitude and longitude in degrees/minutes/seconds, go to Google Maps and and paste your DMS latitude and longitude into the Search box, and Google Maps will show you the applicable map AND display the decimal degrees in the left-hand panel for you to copy.

Using Queensland Place Names database

If you are using the Queensland Place Names database, search for the placename you want. When you have found its entry, it will be displayed in DMS. Copy and paste this DMS data into Google Maps search box. But before, you hit Enter, click in the Search box and delete the “/” (Google Maps doesn’t like it), and the decimal degrees will be returned in the left panel for you to copy.
