We are going to show you how to work with Maps.
Following are the point.
1. Map basic elements 2. Additional graphics elements 3. Map finalization
Map Basic element:-Definition of Map Elements. A map usually contains the following elements: Title (and subtitle): Usually draws attention by virtue of its dominant size; serves to focus attention on the primary content of the map.
- Title the heading of a map
- Compass a part of a map that shows the cardinal directions/other directions (north arrow).
- Key a part of a map used to define symbols on the map and easily find the locations.
- Grid the horizontal and vertical set of lines that show coordinates values on a map.
- Scale the part of the map used to show how big it is in actual size small and large maps adjust in required paper size.
Additional graphics elements:- Maps are the primary tools by which spatial relationships are visualized and analyze . Maps are important documents. There are several key elements that should be included each time a map is created in order to aid the viewer in understanding the communications of that map and to document the source of the geographic information used.

Map finalization:-
- You can turn off some map layers for data that we do not need for this map. Un-check the box next to extra layers. Before we make a map suitable for printing, we need to choose an appropriate projection. This dataset comes in Geographic Coordinate System (GCS) where the units are degrees. This is not appropriate for a map where you want the distances to be in kilometers or miles. We need to use a Projected Coordinate System that minimizes distortions for our region of interest and has units in meters. Universal Transverse Mercator (UTM) is a decent choice for a projected coordinate system. It is also global, so it’s a good default that you can rely on and choose a UTM zone that contains your area of interest to minimize distortions for your region.
- Once you are satisfied with the map, you can export it as Image, PDF or SVG. For this tutorial, let’s export it as an image. Click Composer ‣ Export as Image.
- Save the image in the format of your liking. Below is the exported PNG image.
