Evaluation of the level land suitability for rice crops is used in planning agricultural use so that inhibiting factors and solutions can be found processing to planted. This study aims evaluate crop plants by implementing a geographic information system facilitates accelerates data process research output consideration Tanjung Selor Subdistrict Bulungan District. The variable this was temperat...
In recent years, the advancement of digital technology has led to an increase in data transmission on the Internet. Security of images is one of the biggest concern of many researchers. Therefore, numerous algorithms have been presented for image encryption. An efficient encryption algorithm should have high security and low search time along with high complexity.DNA encryption is one of the fa...
soil salinity is a limiting factor for plant growth and a serious cause of land degradation. field sampling and statistical analysis for estimating soil salinity is expensive and time consuming. estimating soil salinity by spatial statistical models and geographic information system (gis) is recommended, because it saves labor and time. this study was conducted to evaluate the performance of sp...
Amazonia combines semi-continental size with difficult access, so both current ranges of species and their ability to cope with environmental change have to be inferred from sparse field data. Although efficient techniques for modeling species distributions on the basis of a small number of species occurrences exist, their success depends on the availability of relevant environmental data layer...
Comparison of the land suitability variations among the soil map units in viewpoint of pedodiversity indices may provide a good assessment of the soil mapping precision. The main objective of this study was to assess the significance of functional pedodiversity thorough two detailed map units for irrigated wheat and potato for class and subclass levels of suitability in the Faradonbeh plain, us...
چکیده شناسایی رقومی خاک ها بهعنوان ابزاری برای ایجاد اطلاعات مکانی خاک، راه حل هایی برای نیاز رو به افزایش نقشه های خاک با تفکیک مکانی بالا را تأمین می کند. بنابراین، باید روش های جدید بهمنظور بهدست آوردن اطلاعات مکانی خاک با تفکیک مکانی بالا توسعه پیدا کند. به همین منظور مطالعه ای جهت پیش بینی کلاس های خاک با استفاده از مدل های رگرسیونی در منطقه زرند کرمان طراحی گردید. در این مطالعه، مدل های ر...
Proxy information is used to stratify larger areas, and then measurements within each of these strata are agCarbon storage in soils is important to forest ecosystems. Moreover, gregated and multiplied by the area of each stratum forest soils may serve as important C sinks for ameliorating excess (Schimel and Potter, 1995). Soil survey maps and laboraatmospheric CO2. Spatial estimates of soil or...
This paper presents the use of multitemporal remote sensing data for monitoring land cover changes in Acre State, Brazilian Amazônia. The 2000 Landsat ETM+, the 1990 Landsat TM, and 1980 Landsat MSS were used. The 2005 and 2007 MODIS images were also used to map deforestation occurred during the recent years and to map burned areas occurred in the 2005 dry year. The Landsat and MODIS images wer...
in order to determine optimum landuses (in accordance with natural capability) and improve the current land management, landuse planning process was applied by using gis. within the framework of system analysis approach basic ecological and socio-economic , data were mapped. the mapped data were digitized and imported to idrisi and arc/info to build a database ,along with other descriptive data...
