An essential component of soil mapping is classification, a process of assigning spatial soil entities to predefined categories (classes). However, by their nature soils exist as a continuum both in the spatial and attribute domains and often cannot be fitted into discrete categories without introducing errors or at least over-simplification. One approach to mitigate this problem in digital soi...

Modeling and mapping of soil properties has been identified as key for effective land degradation management and mitigation. The ability to model and map soil properties at sufficient accuracy for a large agriculture area is demonstrated using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery. Soil samples were collected in the El-Tina Plain, Sinai, Egypt, concurren...

Mapping and dating soil organic material is of great importance in soil use and evaluation. Yet the most common mapping method of these features is based on visual, qualitative interpretation of air-photos. In this study we examine the feasibility of mapping soil organic material content by using airborne hyperspectral reflective remote sensing methodology. This technique was tested in Henshan ...

Soil Security includes dimensions, soil capability, condition, capital, connectivity and codification (the “five C's”). This article provides a short review on how mapping, digital mapping monitoring systems (SM, DSM SMS) over large areas contribute to these five C's at scales ranging from country globe. Changes the evolution in aims of SM, SMS were driven both by main issues related policy pri...

Sensing and mapping element distributions in plant tissues and its growth environment has great significance for understanding the uptake, transport, and accumulation of nutrients and harmful elements in plants, as well as for understanding interactions between plants and the environment. In this study, we developed a 3-dimensional elemental mapping system based on laser-induced breakdown spect...

In this study, it is attempted to analyze sensitivity and reliability in order to evaluate the liquefaction potential in soil layers in Tabriz. 62 boreholes that had possible conditions for liquefaction were selected. Seismic mapping was simulated using finite fault method and then the effect of soil layers on PGA was estimated. In continue, the liquefaction potential index was estimated and th...

Soil moisture information is of critical importance to real-world applications such as agriculture, water resource management, flood, fire and landslide prediction, mobility, soil hydraulic parameter estimation etc. Many of these applications require soil moisture information at high resolution. While this may be estimated from land surface models, the predictions are often poor due to inadequa...
