ارائه روشی سریع برای حذف اثر هوآویزها از تصاویر ماهواره‌ای MODIS

Yusef Reazaee; Mohammad Reza Mobasheri

Volume 42, Issue 3 , July 2008, Pages 301-311

https://doi.org/10.22059/jac.2013.7753

Abstract
  Due to the effect of aerosols present in the atmosphere on the satellite images, the study of the effect of local aerosols distribution on the satellite images is important. On the other hand, the study shows that the effect of aerosols on the greenhouse gases and consequently on climate is also undeniable ...  Read More

جانمایی دوربین در طراحی شبکه‌های فتوگرامتری صنعتی با استفاده از بهینه‌سازی تکاملی چندگانه

Mohammad Sa'adat Seresht; Farhad Samadzadegan

Volume 42, Issue 3 , July 2008, Pages 313-326

https://doi.org/10.22059/jac.2013.7754

Abstract
  Nowadays, the subject of vision metrology network design is local enhancement of the existing network. In the other words, it has changed from first to third order design concept. To improve the network, locally, some new camera stations should be added to the network in drawback areas. The accuracy ...  Read More

ررسی شرط پیکارد در مسأله انتقال به سمت پائین در تعیین ژئوئید بدون استفاده از روش استوکس

Abdorreza Safari; Yahyallah Tavakkoli

Volume 42, Issue 3 , July 2008, Pages 339-352

https://doi.org/10.22059/jac.2013.7755

Abstract
  The problem of downward continuation of the gravity field from the Earth’s surface to the reference ellipsoid arises from the fact that the solution to the boundary value problem for geoid determination without applying Stokes formula is sought in terms of the disturbing potential on the ellipsoid ...  Read More

تعیین و پهنه‌بندی نرخ ممان لرزه‌ای ژئودزی: مطالعه خاص شبکه سراسری ژئودینامیک ایران

Zahra Mousavi; Behzad Vosoghi

Volume 42, Issue 3 , July 2008, Pages 361-370

https://doi.org/10.22059/jac.2013.7756

Abstract
  A new and significant source of information on earthquake studies has been provided by space geodesy. The data which are gathered by various techniques of space geodesy, can quantify potential of seismic activity in the region of interest. To achieve this goal, the main advantage of extra-terrestrial ...  Read More

مدل سازی خطای تروپوسفری برای مشاهدات تعیین موقعیت ماهواره‌ای

Ali Reza Azmoudeh Ardalan; Marzieh Jafari

Volume 42, Issue 3 , July 2008, Pages 269-278

https://doi.org/10.22059/jac.2013.7757

Abstract
  In this paper a practical method for tropospheric effects on GPS derived coordinates in absolute mode is presented. GPS observations at the permanent GPS stations can be used as source of information for the modeling. The developed model is a time-dependent model and as such differs from usual tropospheric ...  Read More

تخمین جهانی پتانسیل ژئوئید، توپوگرافی سطح دریا و ژئوئید بر اساس مشاهدات ارتفاع‌سنجی ماهواره‌ای

Ali Reza Azmoudeh Ardalan; Hassan Hashemi Farahani

Volume 42, Issue 3 , July 2008, Pages 279-286

https://doi.org/10.22059/jac.2013.7758

Abstract
  Using satellite altimetry derived mean sea level (MSL), geopotential coefficients in terms of ellipsoidal harmonics from recent satellite gravimetry missions, gravity potential values over a grid consisting of 33,486 points at global sea areas are computed and the mean value of the gravity potential ...  Read More

استفاده از الگوریتم ژنتیک در مسائل کوتاهترین مسیر چند معیاره بر پایه سیستمهای اطلاعات مکانی

Parham Pahlevani; Mahmoud Reza Delavar; Farhad Samad Zadegan

Volume 42, Issue 3 , July 2008, Pages 287-299

https://doi.org/10.22059/jac.2013.7759

Abstract
  Multi-criteria shortest path problems (MSPP) are called as NP-Hard. For MSPPs, a unique solution for optimizing all the criteria simultaneously will rarely exist in reality. Algorithmic and approximation schemes are available to solve these problems; however, the complexity of these approaches often ...  Read More

انجام یک مرحله پیش پردازش قبل از مرحله استخراج ویژگی در طبقه بندی داده های تصاویر ابر طیفی

Bahram Salehi; Mohammad Javad Valadan Zoj; Mohammad Reza Sarajian

Volume 42, Issue 3 , July 2008, Pages 327-338

https://doi.org/10.22059/jac.2013.7760

Abstract
  Hyperspectral data potentially contain more information than multispectral data because of their higher spectral resolution. However, the stochastic data analysis approaches that have been successfully applied to multispectral data are not as effective for hyperspectral data as well. Various investigations ...  Read More
