This document discusses contouring, gridding, and surface mapping techniques using Surfer software. It can generate maps quickly from irregularly spaced data by interpolating the values onto a regular grid. The grids can then be displayed and enhanced in Surfer by adding layers, customizing the view, and annotating to create publication-quality maps. Surfer allows users to interpolate irregular data into grids and generate different map types for understanding fields.

2.  CONTOURING
 GRIDDING
 SURFACE MAPPING

3.  It can generate maps quickly and easily
 Maps can be displayed and enhanced
in Surfer. Adding multiple map layers
 customizing the map display, and
annotating with text creates publication
quality maps

4.  Grid based mapping program
 Interpolates Irregularly spaced XYZ data
into a regularly spaced grids
 Grids can be imported from Sources like
(USGS) United States Geological urvey

6. Gridding is the process of taking
irregularly spaced XYZ data and
generating a Z value at each grid node
by interpolating or extrapolating the
data values.
A grid is a rectangular region comprised of
evenly spaced rows and columns.

7. Several different map types can be
created, modified, and displayed with
Surfer providing XYZ Data of any field or
using different techniques for our own
understanding
