This article presents a review of the combined analysis of digital terrain models (DTMs) and remotely sensed data in landscape investigations. The utilization of remotely sensed data with DTMs has become an important trend in geomatics in the past two decades. Models of more than ten quantitative topographic variables are employed as ancillary data in the treatment of images. The article review...

Abstract Thanks to the ability perform imaging and manipulation at nanoscale, atomic force microscopy (AFM) has been widely used in biology, materials, chemistry, other fields. However, as common error sources, vertical drift illusory slope severely impair AFM quality. To address this issue, paper proposes a robust algorithm synchronously correct image distortion caused by slope, thus achieving...

When ordering very high resolution (VHR) imagery of IKONOS or QuickBird a cloud coverage up to 20 % within the scenes has to be accepted. This indicates the high impact of atmospheric conditions to VHR imagery. Beside clouds the images are influenced by haze oftentimes. This haze could be removed using new atmospheric correction algorithms, which were not available for VHR data so far. Furtherm...

This is the User s Guide to the GTM Toolbox a set of Matlab functions and scripts that implements and demonstrates the generative topographic mapping a method for density modelling dimensionality reduction and data visualisation This document gives a brief description of the GTM the content of the toolbox and what is required to use it It describes how to use the toolbox and provides a section ...

Unanticipated and unknown changes in an aircraft’s aerodynamic stability derivatives may cause undesirable effects that render pre-designed control laws unsuitable for maintaining stability. Gradual changes in the stability derivatives may be due to icing on lifting surfaces, whereas structural damage may cause a sudden change. For this study, we use the nonlinear NASA Generic Transport Model (...

PURPOSE To develop a criterion for determining the topographic progression of keratoconus and to analyze the prognostic factors of progression. METHODS Medical records of 211 eyes of 128 patients who had been followed up for more than 2 years on three or more occasions were retrospectively reviewed. Topographic parameters, including simulated K, corneal astigmatism, irregular astigmatism at 3...

Grounded theory method (GTM) is increasingly used in HCI and CSCW research (Fig. 1 ). GTM offers a rigorous way to explore a domain, with an emphasis on discovering new insights, testing those insights, and building partial understandings into a broader theory of the domain. The strength of the method—as a full method— is the ability to make sense of diverse phenomena, to construct an account o...

An edge network deployment consists of many (tens to a few hundred) satellite data centers. To optimize enduser perceived performance, a Global Traffic Management (GTM) solution needs to continuously monitor the performance between the users and the data centers, in order to dynamically select the “best” data center for each user. Though widely adopted in practice, GTM solutions based on active...

The correction of atmospheric effects on optical remote sensing products is an essential component Analysis Ready Data (ARD) production lines. MAJA processor aims at providing accurate time series surface reflectances over land for satellite missions, such as Sentinel-2, Venμs, and Landsat 8. Centre d’Études Spatiales de la Biosphère (CESBIO) the National (CNES) share a common effort to maintai...
