Geometric optical reflectance models provide a physical linkage between image data and forest structure. We developed a “Multiple-Forward-Mode” pseudoinversion modeling approach to produce structural lookup tables for Landsat Thematic Mapper images before and after 1993 partial harvests in New Brunswick Canada. Modeling results validated for stand density, crown radius, and stem counts enabled ...

This study* investigated computer classification performances for forest and other cover types using Thematic Mapper Simulator (TMS) data collected by NASA's NSOOI scanner. Specifically, results based on the use of a common feature selection measure -transformed divergence (TD) were compared to those based on a principal component transformation for the purpose of evaluating the capabilities of...

One of the most prominent tourist destinations in Adriatic coast, city Opatija, is facing a problem concerning seasonal drinking water shortages. The existing resources are no longer sufficient, and attention being given to alternative such as underlying karstic aquifer several coastal springs itself. However, potential area still cannot be estimated due insufficient hydrological data. goal thi...

This paper predicts potential improvements offered by thematic mapper data over multispectral scanner data when utilized in regression estimation of crop .areas. A study comparing LANDSAT data and simulated thematic mapper data is described. Quantitative measures of potential improvements in crop-area estimates of corn, soybeans, and dense woodlands are calculated, and the sensor characteristic...

We investigated the optimal spectral bands for the identification of lighting types and the estimation of four major indices used to measure the efficiency or character of lighting. To accomplish these objectives we collected high-resolution emission spectra (350 to 2,500 nm) for forty-three different lamps, encompassing nine of the major types of lamps used worldwide. The narrow band emission ...

This study involved the evaluation of the characteristics of multispectral scanner data relative to forest cover type mapping, using NASA's NS-OOI multispectral scanner to simulate the proposed Thematic Mapper (1M). The objectives were to determine: (1) the optimum number of wavebands to utilize in computer classifications of TM data; (2) which channel combinations provide the highest expected ...
