    Abstract: A system for analyzing remotely sensed photos of a forest or other areas of interest uses a computer system to increase the variation in NIR data having values that represent items of interest. In one embodiment, a computer system applies a stretching function to the NIR data to increase their variation. The objective spectral stretched NIR data is used to differentiate different types of vegetation in the remotely sensed image. Objective-based Vegetation Index (OVI) values are calculated from the objective spectral stretched NIR data that allow different types of vegetation to be distinguished. In one embodiment, the OVI values are used to differentiate hardwoods from conifers in a digital aerial photo of a forest.

    Abstract: A system for remote quantitative detection of fluid leaks from a natural gas or oil pipeline by use of an airborne platform; including at least one laser light source for nearly simultaneous illuminating two or more target fluids and a background, wherein the two or more target fluids are characterized by two or more absorption wavelengths, and wherein the background has a different wavelength than either of the two or more target fluids. The illumination source is pointed based on a positioning system while in a geometric area along a path two or more target fluids are scanned for using the illumination sources. A signal detector detects the two or more target fluids using quantitative signal processing. Also included are a controller, a path planning and path finding tool for the positioning of the airborne platform, and a communicator for communicating the presence of the detected leak.

    Abstract: From the crop of a predetermined area in a plant field under exposure to natural light, a reflectivity of the light having relation to crop information such as nitrogen content rate is measured by a camera; the crop information as first crop information is obtained from the first crop related formula established in advance for obtaining the crop information from the reflectivity; light is irradiated on crop leaf blades in the same area as the predetermined area and an amount of the light is measured; the crop information as second crop information is obtained from the second crop related formula established in advance for obtaining the crop information from the amount of the light; differences are calculated from the first crop information and the second crop information; the first crop information is obtained from the unknown crop in the predetermined area within the crop field of the same area; the first crop information is corrected based on the differences; and the nutritious diagnosis of the crop in the field is conducted by the corrected first crop information. In conducting diagnosis of crop by measuring the reflection light amount from the crop, since compensation or correction is performed, no great errors occur caused by differences in the measurement locations and the planting densities, and the diagnosis of the crop is simple and easy and, more over, the precision in the measuring is enhanced.
