Analysis, Part I A review of spatial interpolation, specifically spline and trend methods, along with natural neighbors, which we saw in lab last week. LAST LECTURE TODAY In-Situ measurements acquire information about an object when the distance between the object and the sensor is comparable to or smaller than any linear dimension of the sensor. Spatial Interpolation is the process by which we generate continuous raster data from discrete vector (i.e., point-based) measurements using remote and in-situ techniques. The beginnings of terrain analysis, which will be this week’s lecture and lab topic; we probably won’t get all the way through terrain analysis today!
