Three Types of Maps

 

Geographic information systems and cartographic techniques have become more advanced over the years, making it easier than ever before to get specialized maps. But the next challenge is getting these new maps into the public’s hands faster. What’s the best way to get specialized maps into the hands of everyone? Keeping in mind the three main types of maps will make your search easier and your map purchases more rewarding. Read on to learn more about these types of maps.

General reference maps

A general reference map shows the location of various locations on Earth. It highlights certain features and divisions of the land to help you locate places of interest. The road network is also highlighted on these maps. You can use the colours and widths to distinguish the major and minor roads. The following are some of the uses of a general reference map. There are numerous different types of maps. All are available in the catalogue 92-143-G.
Thematic maps

Thematic maps are a useful tool for analyzing the spatial distribution of data themes. They show the geographic distribution of data that is not representative of the area itself. Thematic maps can be qualitative or quantitative. To understand the benefits of thematic maps, you need to ask yourself the question: What is my end-user trying to accomplish? How do I choose the best type of map to meet this purpose? I recommend consulting with a Data Specialist.

Orthophotographic maps

The production of orthophotographic maps requires a process called orthophoto correction, which involves removing relief displacement from an aerial photo and assigning it X & Y coordinates. These photographs can be blended into a map by radiometric or tonal adjustments. The process is complex, and it requires knowledge of the geometric properties of conventional vertical aerial photography. Nevertheless, it has many useful applications in the field of infrastructure assessment, vegetation management, and environmental impact assessments.
Geodesic domes

Geodesic domes are circular, irregularly curved structures that are based on multiple basic triangles. They are also known as omni-triangulated structures. Each basic triangle has a fixed number of vertices, and can be subdivided into multiple smaller ones using the gridlines of a partial great circle. These structures are generally named based on how many vertices would form a complete sphere if the vertices were placed at regular intervals.
Planar projections

There are a number of planar map projections, including orthographic, Mercator, and cylindrical. The choice of a particular projection depends on the final use of the map. Some projections are used for smaller areas, while others are used for large ones. In either case, the projected map coordinates are important for the visual analysis of the map. If you plan to use a map to measure distances between two locations, the projection will be a factor in your decision.

Symbols

Symbols on maps represent areas, points, and other features of the earth’s surface. The symbols on maps help people interpret the information contained on them and relate them to real life. Maps are used for gathering spatial data, such as the location of rivers and lakes. These data are either qualitative or quantitative. To convey the information on a map, the symbols are chosen according to the type of data. Here are a few tips for mapping the world with maps.
Scale

The scale of a map is a way of determining the size of features and illustrating their geographical distances. Using scaled maps allows map readers to easily learn about land features and distances without spending time studying the details of land forms. In addition, scaled maps help tourists better understand the locations of landmarks by visually depicting the distance between these landmarks. Here are some tips to use scale in your maps. Listed below are a few of the ways to make the scale of your maps better.
