Correction of topographic distortion in gravity data
نویسنده
چکیده
The numerical equivalent source is used to correct distortions in gravity anomalies caused by topographic relief. The error involved in the topographic correction is a function of the depth of the equivalent source. The optimum depth of the equivalent source is that which maximizes the smoothness of the calculated anomaly between control points. The technique is straightforward and can be incorporated easily into a standard data processing sequence.

Evaluation and Comparison of Topographic Correction Models Is Applied on the Series Landsat Images Using Spectrometery Data
The effect of topography on the radiance record in satellite image, probably reduce the accuracy of algorithem impliementation on the images . Therefore, to reduce the effect of topography, various correction models based on interaction between light and object needs to be defined. This research introduces lombertin correction model (Cosine model) and non_lombertin correction model (mineart and...
متن کاملInvestigation of the Roughness of the Australian Gravity Field Using Statistical, Graphical, Fractal and Fourier Power Spectrum Techniques
As one of the world’s oldest continents, Australia has experienced a complicated geological and geomorphological history. As such, the gravity field of Australia behaves differently to that reported in other countries. This paper investigates the relative roughness of three types of gravity anomaly (freeair, refined Bouguer and topographic-isostatic) using statistical and graphical comparisons,...

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...

The critical maturation time of central otolith neurons in processing spatial orientations was examined in Sprague-Dawley rats. With the use of immuno-hybridization histochemical methods, we observed c-fos expression in vestibular nuclear neurons responding to transverse movement on the horizontal plane as early as P7 and those to antero-posterior stimulation as early as P9. In the inferior oli...
متن کاملAn Estimation of The Impact of Economic Sanctions and Oil Price Shocks on Iran-Russian Trade: Evidence from a Gravity- VEC Approach
Abstract This article is an empirical attempt to explore the relationship between sanctions (financial and non-financial), oil price shocks and Iran-Russian bilateral trade flows over the period 1991–2014. In contrast to earlier studies in which a gravity model has been estimated through a panel data approach, in this paper the authors apply a gravity model for only two countries and do the es...
