Abstract: Disclosed is a method using an environmental-friendly and artificial freezing technique for sealing and displacement of a soil pollutant. The method for displacement of the soil pollutant comprises: performing an artificial freezing technique on an area and depth of a surveyed contaminated site to form a sealed frozen wall along the perimeter of the contaminated site, by using the excellent permeation resistance function of the frozen wall to seal the contaminated site and to prevent the pollutant from spreading further; selecting a freezing temperature of ?10° C. to ?30° C. according to characteristics of the freezing temperature and precipitation rate of the pollutant, by controlling the freezing rate to 1 cm/day to 10 cm/day, and performing freezing displacement of the soil pollutant from outside to inside using a principle of freezing purification, to concentrate the pollutant; and subjecting the remaining high concentration of contaminated soil to chemical treatment.

Abstract: A method and system are disclosed for creating a real-time, high accuracy mosaic from an aerial video image stream by applying orthorectification of each original video image frame using known ground control points, utilizing a photogrammetric model resolving the object image into pixilation, applying shading to the pixellation, and mosaicking the shaded pixilation of several orthorectified images into a mosaicked image where the mosaicked image is then scaled to the known original image dimensions.

Abstract: A method, system, and computer readable medium for producing orthoimages of the images of a (typically) high-resolution imager of an urban area, the orthoimages of high buildings being imaged with improved accuracy by increasing constraint conditions on the building edges, such as perpendicularity, collinearity. These constraint conditions are merged into an orthorectification model for orthorectifying the images captured at a predetermined elevation, whether by airborne or spaceborne. Constraint conditions may be formed by the building edge points, such as corners, and may be used with a digital building model. Thus, an aspect of embodiments is that the constraint conditions may be directly formed from the building themselves. The higher the buildings, the more effective the constraint controls.
