FieldMove Tutorial
Introduction
FieldMove is a digital mapping environment created to replace the paper map and field note book. The
interface is designed for simplicity in the field and optimised for light weight, ruggedized, tablet devices with
a digital stylus/pen.
A customised version of Move for digital field mapping, FieldMove integrates with both GIS data bases and
heritage paper mapping and allows data transfer to other applications and 3D visualization via MoveViewer.
FieldMove saves data by default in the *.mve format which is common across all Move components. Data
collected in FieldMove can be directly imported to Move for cross-section construction, 3D model building
and kinematic structural modelling.
For advice on suitable hardware for running FieldMove please see the installation guide and www.mve.com
FieldMove Tutorial
This tutorial will cover a typical scenario of setting up a basemap and database in FieldMove, as well as
provide tips on collecting data. Finally it will finish with exporting data to other programs.
An example dataset from Loch Eriboll, Sutherland in the NW Scottish Highlands is provided.

FieldMove Tutorial
Loading a Basemap
You have the option to work with a geo-referenced or non geo-referenced basemap when using FieldMove.
Where possible it is recommended that users work with a properly geo-referenced basemap as this allows
integration with GPS; correctly positioned exported files (such as *.kml export for viewing in Google Earth)
and easy addition of other geo-referenced data.
While geo-referencing functionality within FieldMove itself is limited to defining image extents, georeferenced formats (such as geoTiffs and shapefiles) can be imported directly. (2-point referencing is
possible in Move - please see the help page for the Transform Tool).
Files with referencing information embedded (such as *.shp and geoTiff) will automatically load in the
correct location with the referencing information preserved. (If you are exporting your basemap from a GIS
program, the recommended format is geoTiff).
Exercise 1: Loading a Basemap and DEM
File > Open – in the Files of type drop-down list select GIS Data – Raster Files. Navigate to Kempie.tif
and press Open.
In the Import window that opens you will see a preview of the file (figure 1). Here we have the option to
import a sub-region of the image; however we will import the full extent, press Next.
Figure 1. Preview of the basemap
The next window is for locating the image, as we are working with a geoTiff, “Use referencing information
in file” will be toggled on by default, press Next. (If you are working with a non geo-referenced image this
is where you can define coordinates for corners of your image).
The next screen will show the Datum and Projection that has been read from the file. Press Next to open
the file.

FieldMove
In addition, information on coordinate system and projection type can be read directly from a *.prj file. In
the Import Projection Options window select Show WKT to expand the window (figure 2). WKT stands for
Well Known Type. To assign coordinate system information in a file navigate to any *.prj file you have. For
illustration a file called Kempie.prj is provided. (GIS programs will often have the option to produce a *.prj
file when exporting images).

Transverse Mercator
Save your basemap: File > Save – call it Kempie.
Inserting DEM
Although FieldMove utilises a 2D map view, 3D objects are supported. So although surfaces cannot be
viewed, the DEM can be used to obtain z-values when digitizing certain data types (as demonstrated in
Exercise 3). Contours can also be generated from the DEM and visualised within FieldMove’s map view.
(This is especially useful if you have a satellite image, instead of a topographic map) . Another advantage of
supporting surfaces is that if you are transferring data between FieldMove and Move, data will not be lost.
To load the DEM, follow the same procedure as detailed above (to load the basemap), but instead choose
Kempie_DEM.tif (figure 3).
Save the file as Kempie_Map_and_DEM.mve

appropriate incriment and press Apply/Show Contours (figure 4). Note that the DEM is relatively coarse,
so the contours will not pick up all the subilties that are shown on the topographic map (50 feet contour
interval - to change from metres to feet choose: File > Preferences > Display Units > Elevation).

FieldMove
Transforming coordinate system
In a similar manner to setting the coordinate system on loading, objects in FieldMove can be transformed
to a new datum and/or projection system after they have been loaded. In the Data tab select Document
Properties > Change Coordinate System > Change the Datum and Projection. Select the Datum and
Projection from the drop-down list, or load from a *.prj file (Figure 5).
Figure 5. Coordinate System Window where Datum and Projection Type can be changed
Geo-referencing images in other Move components and working with non geo-referenced data
If you do not have a base map in a geo-referenced format, such as geoTiff, it is possible to geo-reference in
other Move components. It is a 2 stage process, first you add 2 points and rescale the image (see the help
page for the Transform toolbox in Move). Then secondly you define the coordinate system - as described
above. Then once you have saved the image as a *.mve file it can be loaded into FieldMove.
However it is perfectly possible to work with a non geo-referenced basemap. This may be necessary when
the user does not have the information, or time, to geo-reference the basemap, or does not require the
functionality that becomes available through geo-referencing.
Note: on Display Preferences. Depending on the size and resolution of your tablet screen, you may wish
to alter the layout of the FieldMove screen. FieldMove supports the option to have the Model Building and
Data tabs as horizontal tabs towards the top of the screen, or as a vertical panel along the right hand
edge. Users who are using a tablet with a limited number of vertical pixels may find the vertical panel
option useful. To change the layout of the screen go to: File > Preferences > FieldMove Options. Other
display preferences can be found in the Viewer Options tab of the Preferences toolbox.

FieldMove Tutorial
Working with A Stratigraphic database
Data collection can be rapidly speeded up by having a table with the rock units that you encounter in your
field area. If you know in advance the units you will be mapping then it is a good idea to set up a table before
venturing into the field. Alternatively the table of stratigraphy can be created and edited in FieldMove while in
the field.
Excercise 2a: Setting up a Database of Stratigraphy
If you have skipped exercise 1, then open Kempie_Map_and_DEM.mve.
– to open the Stratigraphy and Rock Properties table. By default
Data > Stratigraphy
FieldMove will have a have entries for horizons 1 to 10.
To load an existing database:
File > Open Stratigraphy & Rock Properties – navigate to Kempie_stratigraphy_original.csv > Open – a
database with 6 horizons will open (figure 4).
Note: Stratigraphy and Rock Propeties table is common between FieldMove and Move. For field mapping
most users will not need to make use of the Rock Properties tab. For further information please see the
Stratigraphy help page.
Figure 6. Stratigraphy database in FieldMove
Note: To load old 2DMove databases select 2DMove database (.txt) from the drop down list.
There is a great deal of flexibility in the properties that can be assigned to each horizon. For example you can
choose to add ages to each horizon and create extra attributes – such as thickness. As a minimum you need
Horizon and Colour.

Exercise 2b: Extending / Editing database
To add a new rock unit press the Add Row icon
. Edit the name and colour of this new unit by double-left
clicking in the relevant box, then typing. Change the Horizon name to Lewisian, Colour to bright red and Age
to 2500 (set to 540 by default), to match figure 7.

Save your file as Kempie_Map_DEM_Strat.mve
Configuring and Using the GPS unit
This section applies if you have either an integrated GPS unit, or you are connecting to an external unit via
USB cable or Bluetooth. In addition you must have a geo-referenced basemap with a Datum and Projection
system defined (see Exercise 1 above).
File > Preferences to open the GPS Connection Settings tab. Set the Port and Baud Rate to the
appropriate settings for your GPS device (Figure 8). For further information on this see the technical data for
your GPS device and the Move help page on GPS.

Figure 8. GPS Connection Settings - Active and showing position
Toggle on Enable GPS – you will be shown a summary of the available satellites. Press Apply and close the
Preferences Window.
Your location will be shown by way of a flashing circle on your basemap.
Running the GPS continuously will be likely to drain your battery at a faster rate. To turn the GPS on and off
as required use the icon
towards the base of the FieldMove window.
Data Collection
FieldMove allows for a wide range of data types to be digitized. In the following exercises we will
demonstrate some of the key data types that can be added to your field map. For all data types, their
(figure 9) in the Data panel as well as through:
display is controlled through the Symbols toolbox
File > Preferences > Viewer & Display - for controlling whether Pixel or Metric sizes are used for symbols

For further information on how to use the various data collection tools, please see the appropriate FieldMove
or Move help pages.
Exercise 3a: Collecting Point Information - dips, lineations, fault and fold structures
If you have skipped the first previous exercises on setting up a basemap and table of Stratigraphy then open
Kempie_Map_DEM_Strat.mve.
You are now ready to collect some data!
The Model Building panel lists all the data types that can be collected. In this exercise we will describe how
to collect various different kinds of point data.
DIPS
Below we will walk through collecting a bedding reading, as well as editing it.
Model Building panel > Dip – the Dip Data tool will open. Select the location of your measurement by leftmouse clicking on the map and/or using the position sliders and arrows in the Dip Data tool. Enter a value
for Dip and Azimuth or Strike (figure 10).
12
Midland Valley Exploration
FieldMove Tutorial
Figure 10. FieldMove window showing Dip Data Tool, on left-hand side, used when adding new bedding
readings to the map.
Select a symbol for your reading, e.g. overturned. You also have the option to open the Orientation
Symbols toolbox (
icon next to Symbol Style or through the Data panel) should you wish to edit or
change the default styles.
Select a horizon that your reading will belong to.
As this is your first measurement toggle New Group, then Create Dip (until this point the dip on your map
has been a temporary object that has allowed the dip to previewed).
Editing a bedding measurement
If the Dip Data Tool is open, it must first be be closed. Double-left mouse click on the dip that is to be
edited – this will reopen the Dip Data Tool. Make any changes (to position, orientation, horizon, etc) as
required. Right-click to exit the toolbox, your changes will be applied.
LINEATIONS
The Lineation tool works in a very similar way to the Dip tool, with the user seeing a dynamic preview of
how the data will appear on the map before they commit to creating it. Lineations can be collected according
to 2 conventions: Plunge & Azimuth or Pitch & Direction. Like the other point data collection tools, the
symbols available in the drop-down list can be controlled from the appropriate tab in the Symbols toolbox Lineations in this case.
For further information on the Lineation tool, please see the help page linked from the toolbox.

FAULT AND FOLD STRUCTURES
Faults and Folds can be recorded as points and lines. The line tools (that are demonstrated in the Exercise
3B) are intended for digitizing the course of the features across your basemap. However, the point tools are
designed for capturing the orientation of the fault planes and fold axes at any given location. As such, they
are very similar in design to the Dip tool.
Experiment with the different tools for creating all the point modes described above. An example file is
provided - Kempie_point_data.mve
Exercise 3b: Digitizing Horizons, Faults and Fold Axes
In this exercise we will explain how the 3 line types can be used to digitize horizons, faults and fold axes.
HORIZON
The Horizon line tool is designed for digitizing the boundaries between units. Open the Horizon tool and
experiment with the different creation modes. Note the Format options that allow you to draw solid, dashed
or dotted lines. If a DEM is loaded then the user has the option for the horizon to be created at a constant
z-value (i.e. flat) or along the topographic surface (figure 11). (Note that if you do not use the DEM when
digitizing features it is a very simple process to project them to a surface in Move).
Figure 11. Option to use loaded DEM to obtain z-values when digitizing horizons
FAULTS
The Fault tool allows the user to draw faults of various styles upon their basemap. For fault colour, 2
different pallets are available: right-click on the colours to choose between Default and International
Stratigraphic Chart. From the Structure drop-down list all the common fault annotation symbols are
displayed. Interval controls the distance between the fault teeth symbols. Note that all line styles can also
be easily altered after the line has been drawn. Left click on any existing line in the Map window, at the base
of the model browser a quick editor will open that allows all line options (colour (line and annotation), line
style, interval etc) to be changed. If you wish to change the side of the line on which the fault teeth appear
then press the Flip Symbol button
.
FOLD AXES
Fold axes (anticline, syncline) are drawn by using the Line tool, with different line styles accessed via the
Structure drop-down list. The Line tool can also be used to draw other linear objects, not just folds - choose
the No Style option. In addition, by using the Freehand Creation Mode, users have the option to annotate
any symbol and/or write on the map.
Experiment with the different tools for creating all the lines types described above. An example file that
contains point and line data is provided - Kempie_points_lines.mve

Exercise 3c: Collecting data into the Fieldbook
FieldMove comes with an integrated digital field book. A key advantage of having the field book embedded
is that notes can be geo-referenced on the map in FieldMove. We are going to add a photo taken in the field
into the field book and annotate it as an example of the field book’s functionality.
On the Model Building tab select the Fieldbook icon in the Data tab
or access using
Access Toolbar. Click on Create Fieldbook Pages. Enter the following coordinates:
in the Quick
East (X) – 244628
North (Y) – 957960
Notes can also be positioned visually on the basemap using left-mouse click – in this case the location is on
the shore at Kempie, just below the ‘o’ in “Broch”. Choose your preferred colour (that the note locations will
be shown with on the map) and Page Type (figure 13), press Create.

Using other Move components and Exporting data
FieldMove is designed specifically to be a very ‘light’ and easy to use application that does not have the full
functionality of the rest of the Move suite. It is anticipated that many users will use the 2-dimensional field
map as the first stage in constructing cross-sections and 3D visualisations.
As FieldMove works in map view only, building cross-sections and/or 3D models is restricted to other
components of the Move suite. 3-dimensional surfaces including DEMs can be loaded into FieldMove, but
they are not visible. They key advantage of loading 3D objects is that they are not lost from files when
transferring between Move components.
Working with your file in Move
By default FieldMove saves in the *.mve format common across all Move components. Should you wish to
use the more advanced model building and analysis tools in the rest of the Move suite, you can use any
*.mve file created in FieldMove.
Digital Elevation Models (DEMs) are particularly useful since they allow topography to be extracted along
section trace profiles. In addition, draping of images, dips and horizons will help to significantly enhance
3D understanding. All line and point data can be projected to a DEM in Move using the Project to Surface
tool in the Model Building panel. The process of draping an image to a surface is described in Chapter 5,
Exercise 1 of the Move tutorials.
A 3 dimensional version of the field map (with the basemap draped onto a DEM) is provided (Kempie_3d.mve
– figure 16) so users can explore the tools within Move. If you do not have a license for Move you can still
view the file in 3 dimensions using MoveViewer, our free visualization software.

Exporting data to other Programs
The File Export toolbox (File > Export) in FieldMove allows data to be transferred to a number of key
programs (figure 17). These export formats include:
• *.shp – Variety of GIS packages (Polygons and Polylines only)
• *.dxf – Drawing packages
• *.kml - Google Earth (there are also Google Map and Google Earth views within
Move)
