Landsat Thematic Mapper (TM) data and spectral mixture analysis have been used to estimate vegetation green cover in the Great Basin, western United States, to 4.0% green cover (%GC). In this paper, we compare estimates of percent green cover derived from EO-1 Advanced Land Imager (ALI) data to estimates derived from field-based analyses and to results derived from Landsat Enhanced Thematic Map...

When crops senescence, leaves remain until they fall off or are harvested. Hence, leaf area index (LAI) stays high even when chlorophyll content degrades to zero. Current LAI approaches from remote sensing techniques are not optimized for estimating LAI of senescent vegetation. In this paper a two-step approach has been proposed to realize simultaneous LAI mapping over green and senescent cropl...

Recent studies have highlighted the ecological, economic and social benefits assured by green roof technology to urban areas. However, green roofs are very hostile environments for plant growth because of shallow substrate depths, high temperatures and irradiance and wind exposure. This study provides experimental evidence for the importance of accurate selection of plant species and substrates...

The importance of small urban green areas has increased in the context rapid urbanization and densification tissue. analysis these through remote sensing been limited due to low spatial resolution freely available satellite images. We propose a timeseries on 3 m Planet images, using GEOBIA vegetation indices, with aim extracting assessing quality two different climatic biogeographical regions: ...

This paper will concentrate on the result of a research based on comparative study between two Persian gardens in different micro climates in arid regions. Sustainability could be observed in many aspects and elements of traditional Iranian architecture and landscape architecture, and this method of design has used to solve many problems for many centuries. Gardens of Iran have had special role...

An embedding scheme is developed for the Dirac Hamiltonian H . Dividing space into regions I and II separated by surface S, an expression is derived for the expectation value of H which makes explicit reference to a trial function defined in I alone, with all details of region II replaced by an effective potential acting on S and which is related to the Green function of region II. Stationary s...

The green coverage region is a relevant information to be extracted from remote sensing agriculture images. Automatic methods based on threshold and vegetation indices are often applied to address this task. However, sub-orbital remote sensing images have elements that can hinder the automatic analysis. Also, supervised methods can suffer from imbalance since there is often many more green cove...

The H20 line emission (rest frequency equal to 22235. 08 MHz) regions in W49 and Orion A were measured during June 1970, at three radio astronomical receiving stations: the 120 ft antenna of the Haystack Observatory in Tyngsboro, Massachusetts, and the 140 ft and 36 ft antennas of the National Radio Astronomy Observatory at Green Bank, West Virginia, and Kitt Peak, Arizona. The Haystack-Green B...

It has been suggested that there are two types of chromatic motion mechanisms: signed chromatic motion, in which correspondence across successive frames is based on chromatic content of image regions, and unsigned chromatic motion based on movement of chromatically-defined borders. We investigate whether signed and unsigned red-green chromatic motion are mediated by a genuinely chromatic mechan...
