RGB ORTHOIMAGERY
Orthoimages provide the benefits of both aerial photography and maps, giving a bird’s eye view with the element of scale.
ORTHOIMAGERY SERVICES
The constantly changing conditions in the world around us highlight the importance of having an accurate, up-to-date understanding of the environment and it’s resources. Orthophotography delivers a geospatially accurate representation of your chosen area; a map to what’s there now to help you get where you’re going.
Orthoimages provide the foundation for most public and private GIS systems and is crucial in many mapping and assessment projects.
WHAT IS AN ORTHOIMAGE?
Aerial Photography
An orthoimage is an image collected using aerial photography that has then been corrected to ensure scale, terrain relief, and tilt are represented accurately.
Image Processing
Getting a quality orthoimage is a mathematical process. Ground points, sensor information and digital models all help inform the geometric elements of this type of image. The final product is likely the result of analysis of several photographs.
Resolution and Scaling
Orthoimage resolution represents distance, with each pixel equaling the same space on the ground. This type of scale allows you to make informed decisions about placement and routes.
Top-down imagery taken during peak daylight hours. Available in one to 1000 square mile increments. Geospatially-accurate images of the land surface at 4-inch resolution.
TYPICAL USES FOR ORTHOPHOTOGRAPHY:
• GIS basemaps
• Engineering and routing plans
• Asset management
• Right-of-way mapping
• Alignment maps
• Environmental assessment
Aerial photography as cloud-based web map service (WMS) or cloud-based web map tile service (WMTS).
