About ADOP

1 Meter Resolution Color Infrared Sample

As each day passes, information about our surroundings becomes out of date or incorrect. New subdivisions are built, cities are annexed, and roadways are enhanced or changed all together. Aerial Digital Orthophotography (ADOP) is a special type of photography that is encoded with correct latitude and longitude coordinates, enabling it for use in a number of applications. Photos are taken from a plane above a specified location that allows for coverage of a large area at one time, which is ideally suited for mapping. The image is then loaded into a computer and overlaid onto a base-map for analysis and processing of clear and precise images of the location. The maps that result from Aerial Digital Orthophotography are known as Digital Ortho Quads (DOQ). When data becomes out-dated, a new flight mission is arranged to recapture new photographs and data for the location. Current, comprehensive, and precise map information is a crucial part of the decision making process and analysis of land formations, geographic features, and locations.

The State of Arkansas launched a new state-wide digital ortho-imagery mission to produce an updated version of the popular database. The update process began in winter 2006. When completed, it will become the base layer for subsequent development and maintenance of other geospatial data throughout Arkansas. The images provide one-meter resolution and are built in a GIS compatible format. This fundamental layer serves as the foundation for digital overlays of industrial parks, infrastructure such as water, power, and gas lines, or administrative boundaries, such as school districts or city boundaries.
