Guide: PF 115 – Optimum Gridding Spacing


This module illustrates the importance of acquiring gravity and magnetic data at the appropriate spacing, then gridding that data using a grid increment to capture the shortest appropriate wavelength (Nyquist frequency) without introducing longer wavelengths (aliasing). It will also be emphasized that even though there are numerous gridding algorithms, it is the interpreter's responsibility to honor the data and keep its integrity intact by virtue [...]

Guide: ST 110 – Map Title and Legend


  In general, a map is an aggregate of elements having a common relationship in a distinct space or environment. The maps use coordinate systems to translate three-dimensional real surfaces into dimensional platforms. There are several types of maps such as climate maps, political maps, street maps, weather maps and geophysical maps just to name a few. These maps are tools to relate [...]

Guide: ST 114 – Hand vs. Computer (grid) Contouring


  There is controversy when it comes to data contouring and most of the time one is left wondering "what is my best option?" In this module we discuss the relative benefits of having an interpreter contour “by hand” vs. letting a computer control the contouring of random data points.  In order for the computer to contour a surface containing the data points, [...]
