Thematic images, best done when there is equal area (Albers maps), are maps that show a specific theme in an area. This is a map that shows the different types of soil throughout the forty-eight contiguous states. Many times thematic maps use colors to indicate certain characteristics. For instance, in this map red indicates the driest soils in the country. This particular map will help people in the agricultural business find which places are best for growing crops without using artificial watering techniques.
