T he 1999 Purdue Land Values Survey indicates that the value of an acre of average bare Indiana cropland was $2,092 per acre in June 1999. This was $63 less than the value reported in June 1998, a 2.9 percent decrease. This decline ends 11 consecutive years of increasing values. Cash rents declined from 1998 to 1999 on average land by a little less than two percent to $110 per acre. This is the...

The spatial prediction of land cover at the field scale in winter appears useful for the issue of bare soils reduction in agricultural intensive regions. High variability of the factors that motivate the land cover changes between each winter involves integration of uncertainty in the modelling process. Fusion process with Dempster-Shafer Theory (DST) presents some limits in generating errors i...

The Passage mechanism introduced in this paper provides an easy and intuitive way to transport various types of digital objects by using also normal physical objects without any special identification tags. The current implementation of the Passage mechanism utilizes electronic scales and contact-free identification devices and thus allows for identification of arbitrary physical objects as wel...

[1] The hydrological regime of the Rhine basin is expected to shift from a combined snowmelt-rainfall regime to a more rainfall-dominated regime because of climate change, leading to more extreme flood peaks and low flows. Land use changes may reinforce the effects of this shift through urbanization or may counteract them through, for example, afforestation. In this study, we investigate the ef...

Despite numerous previous studies, relationships between watershed land use and adjacent streams and rivers at various scales in Korea remain unclear. This study investigated the relationships between land uses and the physical, chemical, and biological characteristics of 720 sites of streams and rivers across the country. The land uses at two spatial scales, including a 1-km buffer and the bas...

The aim of this study is to improve the understanding of land changes in the Jiulong River watershed, a coastal watershed of Southeast China. We developed a stratified classification methodology for land mapping, which combines linear stretching, an Iterative Self-Organizing Data Analysis (ISODATA) clustering algorithm, and spatial reclassification. The stratified classification for 2002 genera...

for an optimum use of natural resources in the sustainable development trend, there is a need to identify ecological resources in the shortest period of time and minimum possible cost. in this article, we aimed management ecosystem by assessment of plant covers changes at taleghan township in a twenty year period. percentage of landscape and number of patch were among the metrics that were calc...

extended abstractintroductionin recent years, several studies around the world have shown that land use has a strong impact on water quality, and significant correlations exist between water quality parameters and land use types. generally land use types have adverse impacts on water quality, so positive relationships exist between percentages of these land use types and concentrations of water ...

Cadastre is the essential land register and the basis for many services in the area of land administration and land management. Although European parcel based cadastral system is used in many countries, differences in business processes between countries exist. Through a long period of time these differences have been adapting to development of technology, legislation and other conditions withi...
