Summary

The Maine GeoLibrary Board (MEGIS) has developed a statewide, 5-year, rotating orthoimagery acquisition program for Maine to facilitate state, regional and local government GIS base mapping in an efficient and cost effective program. The State of Maine will use digital orthoimagery for the development of various base map products in a computerized GIS that will support the needs of the state and multiple stakeholders through applications, such as, multi-jurisdictional homeland security mapping applications, state and county emergency management applications, regional and local planning, state and local public safety applications, economic development and other GIS business objectives.

Description

Maine Statewide Orthoimagery Project - All imagery was collected during the 2014 Spring flying season during leaf-off conditions for deciduous vegetation in the State of Maine. The sun angle was at 30-degrees or greater, and streams were within their normal banks. During the flight planning and acquisition, a significant effort was made to limit clouds, snow, fog, haze, smoke, or other ground obscuring conditions in the imagery. In no case does the maximum cloud cover exceed 5% per image. Within the immediate areas of power plants, factories, or controlled agricultural burns some steam or smoke and/or shadows may be visible on imagery.

Lineage 

Process step
When the process occurred 2014-05-13 00:00:00
Description The imagery was acquired using Leica ADS80 (Airborne Digital Sensor) SH81 and SH82. The Leica ADS80 series records all objects, with equal resolution as a 12-bit image, in panchromatic from three different viewing angles as well as additional viewing angles in RGB color and near infrared (4-band) color aerial imagery. Leica GeoSystem’s XPro 6.1 software program was used to perform image processing and aerial triangulation. This package provides the capability to perform digital image processing, aerial triangulation and image rectification. Image mosaicking and final tiling was performed using OrthoVista software.
