Map is a visual representation of an area or selected features of Earth, typically on a flat surface with the help of traditional symbols on the scale which is reduced as compared to actual scale because various types of natural and man-made features are located on Earth and their collective representation is not possible on a single map. Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. Projects and activities currently undertaken by Geoscience Australia as part of the work program. Map scale is often confused or interpreted incorrectly, perhaps because the smaller the map scale, the larger the reference number and vice versa. Scale is important simply because the magnitude of the problems faced in areas such as poverty reduction, the environment, gender issues and healthcare require solutions at scale. Maps are the primary tools by which spatial relationships and geographic data are visualized. A map that is drawn to scale/has a scale means that you can measure a distance on the map and it will be the same on the ground according to the scale.
