Definición

Raster maps, also known as bitmap or image maps, are digital maps that are made up of a grid of pixels. Each pixel contains a value that represents a specific feature or characteristic of the area it represents. Raster maps are commonly used to display satellite imagery, topographic maps, and other types of geographic data.

The pixels in a raster map are typically square and uniform in size. The number of pixels in a map determines its resolution, with higher resolutions providing more detail and accuracy. For example, a high-resolution satellite image might have millions of pixels per square kilometer, while a lower-resolution topographic map might have only a few hundred pixels per square kilometer.

Advantages and Applications

Raster maps excel in conveying detailed information about the environment. They enable users to visualize terrain intricacies, vegetation cover, water bodies, and geological formations accurately. Moreover, raster maps serve as the foundation for creating immersive 3D models, facilitating simulations, analyses, and planning activities.

  • Better User Experience: Raster map tiles impose minimal strain on end users' hardware, enhancing the speed and responsiveness of web maps, thereby making them more user-friendly.
  • Easier to Use: Raster map tiles are easier to use since they come pre-formatted for mapping platforms. This eliminates the need for users to convert their data into the correct format, ensuring no loss of information during the process.
  • Better Integration: Raster maps seamlessly integrate with multiple data sources and display across various web and mobile platforms. This is attributed to the fact that raster map tiles are essentially images, devoid of any computational components.
