GEMLinkW
Updates. Profile Plotting and Basic Forward Modeling for Result-Oriented
Professionals
GEMLinkW,
has been upgraded
with a variety of new features to enable easier visualization
of results and deliver basic forward modeling. Key
enhancements include profile plotting, two-profile display,
multiple profile display, profile and data linking, other profile
plotting options (scrolling, etc.), coordinate conversions,
and simple forward modeling.
Profile
Plotting
As
shown in the following image, users can now display single or
multiple plots in a Profile Window. Selection
of plotted data is controlled through the Data Window
at the top of the display. The Data Window shows the first line
of data in the file and is used to select profiles for plotting.
Plotting statistics are displayed in the area below the Data
Window.
Two
Profile Display
GEMLinkW
enables you to display two profiles in different colours (ex.
total field and gradient) in the Profile window. To set up this
kind of plot:
- Display
the gradient data (column 5 in the Data Window)
- Set the
scaling (Scroll Bar to the left of Profile Window) and move
the plot to the vertical position (Shift + Scroll Bar) in
which you want it to appear
- Right
click in the Data Window in the total field data column. The
total field data is added.
Some
quick experimentation is required because any change to the
Profile Window (i.e. rescaling it) causes only the Active Plot
to be displayed (i.e. you will then have to re-position the
second plot that you want to display).
Multiple
Profile Display
As
shown below, you can also display multiple profiles (up to 9)
in the Profile Window. Remember that the Active Plot is the
last one displayed and the scales in the window correspond to
this data.
Add
data in sequence by right-clicking on the data that you want
to display in the Data Window. You can also change colours by
right-clicking one or more times.
Profile
and Data Linking
Data
in a text file can be easily linked to a Profile Plot. This
enables detailed examination of data values shown in the Profile
Window.
To use the data linking capability:
- Open
the text file in the normal way using GEMLinkW.
- Display
the Profile Window and examine the data.
- When
you find data that you would like to inspect in more detail,
press Shift and Right-Click at the same time. The text file
re-displays the data showing the value that you have selected.
Other
Profile Plotting Options and Controls
A
variety of other controls are also provided. For more information,
please refer to the GEMLinkW help file.
Coordinate
Conversions
The
Coordinate Conversion utility is intended to convert the coordinate
system of the data contained in a file. The supported coordinate
systems are geodetic (latitude and longitude) and Universal
Transverse Mercator (UTM).
Conversion
to a different datum is also supported and it is calculated
using the Standard Molodensky transform.
The utility
creates a new file with the converted coordinates. Optionally,
the file may contain both the original and the converted coordinates.
Simple
Forward Modeling
GEM
has integrated simple block and dyke modeling into GEMLinkW
through the GEMLinkW Tools option. This approach integrates
the freeware from Geophysical Software Solutions and is intended
to provide our users with additional simple capabilities for
working with data in the field or office.
Note
that the block modeling does not accept actual GEM data but
rather creates working models for interpretation based on a
variety of input parameters. For more information, click
