Automated Analysis of Spatial Grids: Motivation and Challenges,ems (GIS) are software systems that are capable of storing and carrying out spatial operations – operations that make use of geographic coordinates – on spatial grids. However, a GIS is typically employed interactively. Remote sensing offers substantial benefits in observing the environment, but the

Geospatial Grids,arth (such as to an ellipsoid) and results in distortion. A variety of map projections are available, and pointers are given on choosing the appropriate map projection to handle trade-offs in the type of distortion associated with each projection. To analyze multiple geospatial grids, it is necessar

Global and Local Image Statistics, In this chapter, different definitions and methods to obtain distances are considered. These include distances between points, distances from a point to a cluster of points, and distances between two clusters. Fast Euclidean distance transforms are introduced, and considerations of when to choose o

Identifying Objects,of pixels that together form a real-world entity such as a mountain range, city, or a thunderstorm. Commonly, objects are formed by combining high-valued pixels that are connected into objects. This is done using a process called region growing. Once candidate objects have been identified, it is pos

D. K. Likhi,C. Sabita,Akanksha Rao encode every relationship. Another challenge with creating automated algorithms to analyze spatial grids is that low-level image processing operations are rarely sufficient, so domain knowledge needs to be incorporated. Hence, in order to create an automated algorithm to operate on geospatial data,
