Effect of the sampling design of ground control points on the geometric correction of remotely sensed imagery
The acquirement of ground control points (GCPs) is a basic and important step in the geometric correction of remotely sensed imagery. In particular, the spatial distribution of GCPs may affect the accuracy and quality of image correction. In this paper, both a simulation experiment and actual-image analyses are carried out to investigate the effect of the sampling design for selecting GCPs on t...
متن کاملGround Control to Major Tom: the importance of field surveys in remotely sensed data analysis
1. BACKGROUND Recent increases in the availability of remotely sensed data have created a remarkable opportunity to measure fundamental indicators of human well-being at a global scale. These new data sources, such as satellite-derived climate variables and remote sensing imagery, are particularly valuable in locations where direct on-site data are rarely collected, such as developing countries...

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...
