They include many different layers such as boundaries, surface cover, roadways, and hydrography and are used in GIS mapping applications. This map layer shows the waterways on Beaufort, SC along with roadways, railroads, and parcel boundaries.
DRG
Description: DRG stands for Digital Raster Graphic. A DRG is a scanned image from the a United States Geological Survey made for computer usage. This is a type of topographic map so it shows relief using contour lines. This computer map shows us a surveyed area generated on a computer and shows both aspects of the landscape and the relief.
Isopleths
Description: Isopleths are lines on a map connecting points that have a given constant variable. These maps are viewed statistically and are usually used for mapping surface elevations, atmospheric pressure, and amounts of precipitation. This maps constant variable is the amount of precipitation across the United Stares and shows us these values in centimeters.
Isopach

Description: Normal aerial photography can make it hard to decipher different colors and shades of the landscape. Infrared Aerial Photos use colors to make the landscape easier to make out. Black and White Aerial Photos do the same thing except a black and white scale is used. We are able to see is what is reflected from the landscape. In this picture the black and white aerial photo clearly shows roads, water ways, and neighborhoods using black and white.
Infrared Aerial Photo
Description: Normal aerial photography can make it hard to decipher different colors and shades of the landscape. Infrared Aerial Photos basically make seeing and deciphering what makes up the landscape easier. Our eyes can not see infrared. What we are able to see is what is reflected from the landscape when a infrared aerial photo is taken. Trees, plants, and beaches reflect light well making it easier for us to see them on maps. In this picture the infrared photo makes it easier to pick out areas of the landscape such as wooded areas, open space, and areas with sand.
