A three day symposium was held in honor of the late Maurice Ewing at Arden House, Harriman, New York on March 28-31, 1976. The symposium is the first of a planned Maurice Ewing series of symposium to be held biennially. The American Geophysical Union has agreed to publish the proceedings of the symposiums in a special Maurice Ewing series. This volu…
The assumption of lognormal (parent) field size distributions has for a long time been applied to resources apprasisal and evaluation of exploration strategy by the petroleoum industry. However, frequency ditributions estimated with observed data and used to justify this hypotesis are conditional. Eximination of various observed field size distribut…
A feedback or validation procedure is an essential feature of petroleum resource evaluation methodology. The purpose of such a procedure is to provide assessors with a mechanism which enables them to validate input data and challenge geological interpretations. In our method, pool sizes can be estimated by rank from the pool size distribution and th…
In the usual geostatistical practice, global estimation of a deposits is made by running the estimated values obtained by kriging for each individual block in the deposits. When all blocks are identical in size it is equivalent to simply accepting the average of all the estimated values as the global estimated value. Variance of this estimator is ex…
This third issue of the Asian-Pacific Remote Sensing contains 17 articles on topics as varied as the detection of aeolian sand accumulations via satellite images, urban green spaces study through aerial photography and the usefulness of a contextual classification algorithm for land-use/land-cover mapping. we feel confident that each reader will fin…
Early microscopic examination of coals and coal macerals began with the use of transmitted and then reflected light microscopy. These methods were limited by the resolution and optical quality of the microscopes used. Improved microscope technology and the development of oil immersion techniques led to advancements in coal petrology. Introduction of…
The regional Remote sensing Programme (UNDP/RAS/86/141) was initiated in March 1983 and is a project of the governments of Asia and Pacific. The United Nations Development programme is providing financial support to this project. National agencies for remote sensing and related ministries in the in the region are the co-ordinating agencies for the R…
