Digital Images on the Dime

About this technology

Overview

In 1997, Positive Systems received technical assistance on algorithm research for radiometric corrections, specifically to address bi-directional reflectance in aerial photography. This work was conducted under a Space Act Agreement with Stennis, coordinated by the Montana State University TechLink Center. The prototype software developed under the agreement was subjected to rigorous testing and subsequently deemed ready for commercialization under the Digital Images Made Easy (DIMER) moniker. Now marketed worldwide, DIME significantly increases the usefulness of satellite and aerial information by resolving major problems associated with digital imagery. Like piecing a jigsaw puzzle together, DIME can integrate a series of raw aerial or satellite snapshots into a single, seamless panoramic image, known as a mosaic." The "mosaicked" images serve as useful backdrops to GIS maps-which typically consist of line drawings called "vectors"-by allowing users to view a multi-dimensional map that provides substantially more geographic information. In addition to its mosaicking capabilities the software reconciles color differences between like features in neighboring images. The technology is helping to map illegal immigrant and smuggler trails along the United States-Mexico border."
