[1] The spatial distribution of subsurface soil textural properties across the landscape is an important control on the hydrological and ecological function of a watershed. Traditional methods of mapping soils involving subjective assignment of soil boundaries are inadequate for studies requiring a quantitative assessment of the landscape and its subsurface connectivity and storage capacity. Ge...

Airborne electromagnetics (AEMs) is increasingly being used across the globe as a tool for groundwater and environmental management. Focus is on ensuring the quality of the source data, their processing and modeling, and the integration of results with ancillary information to generate accurate and relevant products. Accurate processing and editing of raw AEM data, the topic of this article, is...

This is the second of a two-part tutorial, the first part of which is in Curtis (2004). Between Parts A and B this tutorial provides a theoretical framework from the field of Statistical Experimental Design (SED – a field of statistics) within which modelbased survey and experimental design problems and methods can be understood. Specifically, these tutorials describe methods that are pertinent...

Busstop, a spatio-temporal GIS prototype for geophysical studies, is presented. It includes a metadata representation system, a visualisation subsystem, and a spatio-temporal extension of a classical map algebra. It also takes an active approach to integration with existing non-GIS data handling and analysis programs. Busstop has been used for minor geophysical case studies with some success, b...

A series of digital data sets were compiled for input into a geophysical data base for a one degree quadrangle in Arizona. Using a Landsat digital mosaic as a base, information on topography, geology, gravity as well as Seasat radar imagery were registered. Example overlays and tabulations are performed. The role of remote sensing in environmental inventory has evolved into an important supplem...

the study area covers the northern part of the baft geological map (scale of 1:100 000 ). several porphyry and vein-type mineralization are reported from this area. a topic that is discussed in the mineral exploration community is the use of remote sensing and airborne geophysics for porphyry type mineralization. which one is more reliable and efficient in hydrothermal alteration mapping? airbo...
