INTERACTIVE DIGITAL TERRAIN MODEL ANALYSIS IN ATTRIBUTE SPACE

Digital Elevation Model Error in Terrain Analysis

Digital Terrain Analysis

The development and application of the TAPES: Terrain Analysis Programs for the Environmental Sciences software tools described in this book was motivated by our view of the world as a stage on which a series of hierarchically scaled biophysical processes are played out (Figure 1.1). This approach is useful because it can handle the complexity of individual landscape processes and patterns as w...

A Systematic Classification Research of Topographic Descriptive Attribute in Digital Terrain Analysis

Topographic attributes (TAs) play an important role in quantitatively describing the characteristics of landform and its structure. At present, TAs are classified from different views by many scientists being from various fields. However, there are still some urgent problems that need to be clarified about TAs. The relationships and differences of various TAs are not revealed and a mature, wide...

Digital Terrain Model Data Structures

This paper describes pertinent digital terrain model data structures, namely, grid/raster, quadtree, and triangular irregular network. A basic concept of DIM data structure is also explained. The aspects of TIN storage, TIN data structure conversion, advantages and disadvantages of each structure are discussed. A complete data structure conversion program is also presented. n. 1.0 INTRODUCTION ...

Using Interactive Search Elements in Digital Libraries

Background and Aim: Interaction in a digital library help users locating and accessing information and also assist them in creating knowledge, better perception, problem solving and recognition of dimension of resources. This paper tries to identify and introduce the components and elements that are used in interaction between user and system in search and retrieval of information in digital li...
