Abstract

Mapping of the microrelief structures using multitemporal very high resolution Space imagery

Highlights

  • Many types of big-scale environmental research demand information about microrelief [9], [12]

  • Studies of other authors show that the very high resolution space imagery collected in the stereo mode makes it possible to produce the Digital Surface Models (DSMs) with 5 meter accuracy of height measurements in the case of images georeferenced without ground control points (GCPs) [1]

  • In the result of DSM extraction produced for both stereo pairs, we generated two surface models

Summary

Introduction

Many types of big-scale (i.e., detailed) environmental research demand information about microrelief (landforms with dimensions from few meters to a few tens of meters) [9], [12]. Studies of other authors show that the very high resolution (sub-meter spatial resolution) space imagery collected in the stereo mode makes it possible to produce the DSMs with 5 meter accuracy of height measurements in the case of images georeferenced without ground control points (GCPs) [1]. GCPs help to reduce errors and to produce DSMs with sub-meter accuracy [8], [11], and with accuracy higher than 10 cm in the case of Evgeny Panidi et al.: Mapping of the microrelief structures using multitemporal very high resolution Space imagery additional reduction of systematic biases [2].
