How to use Free Gold Maps

This website allows users to select one or more mineral commodities from a list on the 'Select' page, and have the results displayed on the 'Map' page by then using the 'Fetch' button.

Useage proceedure is to first visit the 'Options' page and set your desired vales. Marker Size allows the user to choose how large each map marker is. The Maximum Records To Retrieve At Once slider allows the user to adjust how many records each 'Fetch' returns based on how slow their Internet connection is, and how slow their web browser is. Automatically Fetch More Records can be set so that when the map is zoomed out, or the map boundaries change, or if the map center is changed, new records will be fetched automatically without the need to use the 'Fetch' button. Data Size may be set depending on how much detail the user wants from the database: data size set how much information is displayed when the user 'left clicks' on a map marker. To recenter the map and zoom in, use 'right click' on the mouse.

Once commodies are selected from the 'Select' page, the user may use the 'Fetch' button to return records, if any. The records nearest the center of the map are placed first. The user may retrieve more records (up to 2,500) by changing the zoom level on the map, or by moving the center of the map, and use 'Fetch' again.

The 'Clear' button removes all markers from the map.

The 'Location' option will recenter the map based upon the user's location, if the user's browser is allowed to do so.

The 'Info' page shows the user information about the map, including total record count.

To reduce your browser's memory and CPU usage, the total number of markers placed on the map has been set to 2,500. If you zoom in or out when the map holds many markers, the map will take several seconds (each time you do so) to update.
