What are remote sensing maps, aerial maps, electronic maps and image maps? What's the difference?

1. Different properties

1. Remote sensing map: It is a map that uses remote sensing images and certain map symbols to express the geographical spatial distribution and environmental conditions of mapping objects.

2. Aviation map: It is the collective name for various special maps used in aviation.

3. Electronic map: It is a map that uses computer technology to store and consult digitally.

4. Image map: refers to a map with ground remote sensing images.

2. Different characteristics

1. Remote sensing maps: Image maps have rich ground information, clear content, and clear and easy-to-read images, fully demonstrating the dual advantages of images and maps. .

2. Aerial maps: Aerial maps only represent geographical elements related to flight, such as oceans, rivers, lakes, terrain, main residential areas, forest ranges, railways and major highways, etc.

3. Electronic map: It can be quickly accessed and displayed; it can realize animation; it can display map elements in layers; it uses virtual reality technology to make the map three-dimensional and dynamic, allowing users to have an immersive experience. feel.

4. Image map: The characteristic of image map is that it uses surface images to directly display physical geographical elements and certain easily identifiable features, such as terrain, landforms, water systems, forests, cultivated land, residential areas, and road networks. wait.

3. Different elements

1. Remote sensing maps: In remote sensing image maps, the map content elements are mainly composed of images, supplemented by certain map symbols to express or explain the mapping objects.

2. Aviation map: represents the geographical elements related to flight.

3. Electronic maps: In the early days, bitmap storage was used, and the map scale could not be enlarged or reduced. Modern electronic map software generally uses geographic information systems to store and transmit map data.

4. Image map: Using aerial photos or satellite remote sensing images, through geometric correction, projection transformation and scale normalization, certain map symbols and annotations are used.
