Processing remote sensing imagery for accurate and complete information extraction requires specialized software and methodologies; GISmatters has decades of experience in this field, using off-the-shelf tools and developing custom image-processing software with a wide range of data and formats, from black-and-white aerial photos to hyperspectral imagery - even medical imagery! We can take the data from raw digital values to fully rectified, georegistered, and processed information products.
Remote Sensing: Transformations
The images at right show a natural-color (when you roll the mouse pointer over the image) and Principal Components version of a Landsat scene. The PCA version displays the first 3 principal components with red, blue, and green colors, respectively. This transform maximizes variance in the first components and eliminates correlation between the components, making it well suited for information- rich image display, image classification, and image compression.
