Analysis of Remotely Sensed Data for Detecting Soil Limitations
During 1971 and 1972 a detailed study was conducted on a fallow field in the proposed Oahe Irrigation Project to determine the relationship between the tonal variation observed on aerial photographs and the properties of eroded soil. Correlation and regression analysis of digitized, multiemulsion, color infrared film (2443) data and detailed field data revealed a highly significant correlation ...
متن کاملUncertainty Characterisation in Remotely Sensed Soil Moisture
Cover: A convective thunderstorm arrives near the small town of Hombori (Mali) during the AMMA field campaign (August 2005). This region is located in the Sahel, a transition zone between the Sahara and the Sudanian Savannas and stretches across the African continent. In this region, the spatial distribution of soil moisture affects the regional climate system including the spatial distribution...

متن کاملCommercial Remotely Sensed (CRS) Data
Natural disasters can severely impact transportation networks. In the hours and days following a major flooding event, knowing the location and extent of the damage is crucial for incident managers for a number of reasons: it allows for emergency vehicle access to affected areas; it facilitates the efficient rerouting of traffic; it raises the quality and reduces the cost of repairs; and it all...
متن کاملVerification Using Remotely Sensed Data
Soil moisture is an important hydrologic variable that controls various land surface processes. In spite of its importance to agriculture and drought monitoring, soil moisture information is not widely available on a regional scale. However, long-term soil moisture information is essential for agricultural drought monitoring and crop yield prediction. The hydrologic model Soil and Water Assessm...
