Introduction
The ENVIMAP software
The ENVIMAP processing system is a PC-based software system designed to
specifically process Scintrex ENVI-MAG ground magnetometer data into report
quality maps. The system can produce contour maps of total magnetic field or
vertical magnetic gradient data on a variety of printers.
The processing system works with spatially positioned data—that is, data that
have a ground location (X,Y) and one or more associated readings (Z values) at
that position. For ENVI-MAG data, there are two possible Z values:
1. Total-field—the total magnetic field in nanoTeslas (nT).
2. Gradient—the gradient (rate of change) of the total magnetic field in
nanoTeslas per metre (nT/m).
Processing system steps
The sequence of steps in using the processing system are:
1. Prepare the data
The data must first be collected using the ENVI-MAG (see Section B -
Applications). The ENVIMAP system will copy the data from the ENVI-MAG
and create a file on your computer. This file can be directly processed to
produce a map. If you are surveying a large area and have to dump your
data several times, ENVIMAP will also allow you to merge your data files
quickly and easily before you make a map.
