What is Digital Mapping ?
Conducting mapping with digital electronics and
information technology (IT) tools:
(pen tablet portable PC’s, GPS, and digital base maps)
GeoMapper is the data capture or mapping “front end”
Visual User Interface to the PenMap 3-D GIS system
A good place to start is with the maintenance
of the system: Charging of tablet PC and Li-ion
batteries- in a secure place
A mapping vest is an excellent field tool to protect
the system outdoors as the tablet can be conveniently
carried in an inside pocket of a vest thus providing
both convenience and protection for the pen tablet
leaving both hands free while meeting ANSI visibility
standards

PCMCIA
Flash Card
DGPS
An external GPS antenna on the shoulder of
A vest keeps a more continuous GPS fix
even when the tablet is placed in the
inside vest pocket for walking.

GPS accuracy depends on:
The number of satellites visible to the receiver
Strength of satellite signals (S/N)
Geometric position of satellite in the sky (constellation)
Differential corrections- require an unobstructed view of the
southern sky- suggestion: put your external GPS
antenna on your shoulder and face north when taking
GPS readings- this gives you the best chance of receiving
the Differential GPS signals from a geo-stationary
satellite in the southern sky
The Globalsat BC-337 uses only WAAS differential
corrections which are available only in the USA

Mathematical requirements
x, y, z, time are 4 unknowns
Need 4 independent equations
At least 4 satellites are needed to get a 3 dimensional location of
x, y and z
The more satellites the better
Our GPS units required at least 4 satellites with a signal to noise ratio
about 32

The quality of GPS varies during the day with the constellation of
Satellites available at any one time
Satellite Geometry given as:
HDOP = Horizontal dilution of precission

Good GPS fix but
Not differentially

HDOP =1 is ideal
Have to pposition yyourself so that the
GPS receiver is in direct line
with a satellite sending down the

To find which COM port your card GPS unit is using,
go to Start> Control Panel>System>Hardware>
Device Manager>Ports (COM & LPT)>Then
Read what COM port is shown at the end of

Click Status Box to see satellites
2 main modes of using the GPS:
(1) Averaged fix for a static position (stop and count 15 seconds)
(2) Minimum distance and out-putting locations as you walk;
set to 10 meters, 50 meters etc, at least the distance of the
likely uncertainty of the GPS fix
15
Create a new Project Legend
Decide on the name of your new Project.
Create a new Directory (folder) with the same name as your new
Project in the PenMap 5 Directory.
Within the new Project Folder create two more directories:
Rastermaps and Vectors Maps
All of the subsequent files for this Project Area should go inside
this Project Directory, for example: digital base map files
such as ortho-images, topographic map files, etc.
Then start up GeoMapper and go to the Project Legend screen
and click on Create New Project Legend
For each new Project, repeat this process
16
GeoMapper Project Manager lets the user
define the local stratigraphic column
Start a new Project Legend
Plan the Legend on paper showing the stratigraphic column in terms of
Formations and also Lithologies. That way you can map individual
outcrops by lithology, then later make a colored overlay showing the
formations if you wish. Keep formation is time-stratigraphic order
Decide on the name of the Project Folder. Then click on GeoMapper
and instead of going to a green button, go the lower right and click on
Create New Project Legend. To the right of Project Legend
Description, type in the new Project name. Beneath this to the right of
Project Legend Name: GM-type a 4 letter abbreviation of the Project
name, eg GM-XXXX. The lowest entry should say Project Seed Name:
GM-Geo. If it doesn't type Geo. Then hit OK
You should see now on the bottom of the List of Project areas on the
bl screen your new Project

With the pen stylus, drag the lower right corner down and to the right to
maximize the screen. Use the right hand scroll bar to go down to the
lowermost buttons for the Oldest formations. These will appear in
GeoMapper on the left hand side of the button array so the buttons get
younger to the right.
17
What customization means is editing the buttons on the Formations
tool bar to: (1) appear with age and formation abbreviations instead of
numerical sequence 1, 2, 3 etc. and making the color of the formation
on the map what you want
(2) edit the Lithology tool bar to show the lithologies you desire either
in areal infills of closed polygons for outcrops
Or lithological symbols plotted along lines
as in a open pit bench
18
GeoMapper Legend Maker
Takes less than 1 hour using only point and click skills
A hard copy of the legend can be printed
Buttons are edited
Change infill color Buttons are edited
Formations replace numbers
Lithologies are replaced
User-selected color infill
patterns
Selectable pre-programmed lithology
patterns (Compton, 1985)
Example: A customized Formation tool bar for a statigraphic section
is shown below running from oldest formations on the left to youngest
on the right with unedited button still represented by numbers

Each Formation button now shows the map color and the Formation
symbol abbreviation in correct stratigraphic order youngest to the right
Before making a new stratigraphic section, plan it out carefully so you
do not omit formations and have to insert them later. It is much easier
to place them in the correct order at the outset.
19
On the pull down menu, go View to Zoom to Custom to 800%
Now using the Paint tools on the left, make this button look the way you
want. Typically we use a time stratigraphic symbolism, eg Pp for
Permian Phosphoria Formation. Customize all the colored button you
want and type in their formation name. Also click on the colored
rectangle to the immediate right of each Formation name and select the
color you wish for display on the map.
Now the right hand half of the Legend screen is for you to make
analogous changes to the Buttons, lithologies, and select the pattern you
wish to have shown for your outcropt. Do it step by step as before.
When you are done, click the Pink Save Legend button and hit Exit

g
yyou jjust made. Wait until the hard drive stops.
p This
may take several minutes.
To Make sure that the Symbols rotation option is ON, Click on the great
SETUP button shown below that is in the Upper row second from the
upper right.
21
Then click ON the Prompt for orientation and click OK and close this
screen. Hit a red SAVE button
Loading Digital Base Maps
The Project Manager creates a new directory each time you
make a new Project Legend in the C: PenMap 5 directory.
To load digital base maps, you need to navigate to the Project directory
where you wish to upload digital base maps.
For example, if you created a Project Legend for the Whitehall area,
a new GeoMapper Project legend would appear.
Navigate on the C: drive to the Penamp5 folder and find the directory
for the project you want, eg Whitehall.
Inside this folder, create 2 new directories, one labeled Rastermaps
and a second labeled Vectormaps
22
GeoMapper/PenMap can use four different types of base map files
simultaneously so that any of the 4 layers can be hidden or shown
The four types of graphics files are and the folder they go are are:
Vector
Vectormaps folder
Raster (bmp type)
Rastermaps
DRG (digital raster graphics eg geo-tiff)
Rastermaps
Shapefiles
Vectormaps
Load you digital graphics files into the correct folder, either Vectormaps
or raster maps for the Project directory of interest.

Vectormaps and Rastermaps. This helps keep your files organized
For using tif files as base maps, the raw tiff file needs to have been
georeferenced to the same UTM and reference ellipsoid that
you are using in the field with the GPS.
23
Click on the blue Select Base button
This frame appears showing the 4 different map types; each of these has
a Browse button to local the files you want to load
For Vector maps which are usually line graphs or vectorized topography,
after you copy the vector files into the Vectormaps folder, you can
use Gazeteer button to assemble a collection of vector maps.
Name this collection with a 4-letter name.grp
The Browse button is to select from these vector groups after they
have been made.
24
Raster Map group is accessed by first pressing the Convert bitmap
type
Four different types of bit mapped image files can be used:
Tif, PCX, BMP, and JPEG. You can if you wish, convert
your bitmapped file to a DRG list so that two different layers
can be used, one as a Raster map, and another as a DRG
DRG List Used is started by pressing Create/Edit DRG list
Then Add new sheets
Select the files you want
Hit Open, then Save and Exit
25
Shapefile list used is done in the same way as with the other file types.
Now that you have loaded your digital base maps, you can hide them
as you wish to display only 1 one more.
Click the Blue Option Base button
26
To hide any of the 4 types of base maps, click on the Hide buttons
shown below- them hit the redraw button
When the DRG and Shapefiles are loaded, hit OK, then YES twice when
asked to update the current survey area. Disregard the message
Division by Zero.
To Save this collection of maps, go to File and Do a Save As to save the
combined map file as assembled. The next time you open GeoMapper,
go to the green Open Map button and you can click on this file so that
you need only load these base maps once.
Note on naming files: Any filename should be 8 characters or less long
in front of the ".pts" eg 12345678.pts
27
Mapping -now that you have base maps ready to go
Go to the Project you want and click on a
green Start Mapping button
28
Each of the button icons in the StartGeo tool bar menu activates
specific functions. No pull down menus are necessary
The buttons read like a book: start at the top left, move right & down.
They are also colored coded like a traffic light:
Green: Go Ahead, the most commonly used buttons
Yellow: Caution, less commonly used
Red: Dire situations for Saving your work and Exiting.
Color coding classifies the buttons into similar groups and also shows
which ones are most commonly used and which are used
only under special circumstances
Most mapping is done with Green buttons: all others are special
functions:
Blue: select base maps files (topography, ortho-image)
Purple: GPS

Button Tool bars
Tool bars are arrays of green buttons which can be touched by
the pen stylus to bring up groups of buttons
organized that do most of the work of geological mapping:
Lithology
Structure
Formations
Mineralization
Alteration
These tool bars can be used in whatever sequence a mapper decides

33
Once you are panned and zoomed into the area of interest where
mapping can begin, we will show how to map an outcrop by
drawing a perimeter around the area of exposed rocks of one
lithology.
Click on the Lithology button
The Lithology toolbar opens up and draws the map shown before
Notice that on Lithology Toolbar, other common features remain:
Contacts, faults and strike and dip (both azimuthal and down dip)
This saves time by not having to change tool bars very often
Notice the red box around the
Lithology button. This shows that
the Lihtology tool bar is open
Now select an Area fill type for the lithology you want
Using the pen stylus touch the screen in a number of points demarking
the perimeter of the outcrop but do not complete the pattern.
To complete the polygon, click on the Gray Complete button and hit OK
34
Always after hitting a Complete button, click on OK to complete
entering the data into the GIS data base
A closed polygon is now filled in the selected lithology showing the
outcrop.
Next map a contact. Click on the well-located (solid line) contact
button and touch sevel points along the contact.
Hit complete
when done
35
Select a second aerial lithology button and draw another polygon
using Complete to close the last gap of the polygon.
Now let’s map a fault (in blue).
Click on the well-located (solid blue) fault button
Click on severla points along the idealized fault
Assume that the fault cuts off the contact shown in black. As you
continue to use the pen style to put in points along the fault,
you can snap onto the SE end of the black contact lie to share
that one node. Simply click on the SNAP button
36
Click on the end node of the black contact line, then hit Free Node
to go back to inputting nodes using the stylus rather than
snapping on existing nodes. Hit complete when done, then OK
Let’ add a Color infill to show
the Rock Formations
Click on the Formations
tool bar button
Formations are colored infill areas. Select one of them, eg Formation 1
and start to outline an area. When you want to snap onto
Existing nodes on

Plotting a Strike and dips involves a symbol in GeoMapper
Most of the Green colored toolbars for Lithology, Structure, and
Formations all have the Strike and Dip symbols as well as the
most common kind sof contacts (solid and dashed lines) plus
faults so it is unnecessary to change tool bars to use a common
symbol.
Some of the symbols occur twice without and with a “D” notation
which refers to down dip direction. Symbols without a “D”
use an aziumth and dip or plunge.
Use the Right Hand Rule is determining the azimuth of the strike line,
ie, as you look along the strike line, if the bed dips towards
39
Your right, then read the north arrow of your compass. If the bed dips
to the left, read the south end of your compass or add 180 degrees to
the former reading.
Click on the Strike and Dip symbol (without the “D”)
Zoom in so that the map scale is about 1:1000 or so.
40
Click on the Azimuth field and enter

Explanation of WAAS GPS system:
http://en.wikipedia.org/wiki/WAAS
Geostationary satellites used for WAAS in the US
See satellites # 48 and 51 in the map on the next page which are
located above the earth’s equator
Satellites with PRN numbers greater than 32 are geostationary

to its ability to acquire and maintain a signal lock in urban or densely

time it takes for a GPS receiver to lock onto the satellite signals and
determine the initial position. The enhanced abilities of the SiRFstarIII
chips are made possible by several features:
A 20 channel receiver,
receiver which can process the signals of all visible GPS
and WAAS satellites simultaneously.
Reviewers have praised the SiRFstarIII chipset for its superior sensitivity
and tracking capabilities.[4]
Changing Symbol Sizes
To change the symbol size retroactively within a library of PenMap
symbols is to reset the symbol. So for the strike and dip symbol you will
need to reset the symbol within the symbols library for the GeoMapper
legend(s). Specifically...
Phase 1
1. Open the PTS file you want to edit.
2. Export the Map File (export a UNV file).
Phase 2
1. Open a PTS seed file, such as Geology.pts or Berk2005.pts (A PTS

2. For relevant scale click on the Strike N Dip button and plot a strike
and dip symbol.
3. Create a strike an dip symbol that is twice as big by using the
Graphic>>Line with Method>>free selections from the menu bar and
pull-down the Default GIS Name selection.
75
4. Click on the Set Symbols button.
5. Scroll-down and select the STKNDIP GISname symbol-box.
6. From the menu select the Wipe option found within one of the menu
items in the symbol toolbox menu.
7. Scroll-down to select the STKNDIP GISname symbol-box, again.
8. Then select the Add symbol graphic from window option from the
menu items.
9. Click and Drag to select the new (twice as large) strike and dip symbol
made.
10. Select File>>Save
11. Toggle-on to Replace existing file.

Phase 3
1. Copy the symbols file just updated/created named GM-Geo.slb into
the Configs folder of the pertinent legend folder found within the
GeoMap directory. (if it is a map file of the Berkeley Hills project then
the corresponding legend folder is named GM-Berk.)
2. Also copy the file into the Configfiles directory of Penmap.
Phase 4
1. Start GeoMapper
2. Click on the Load Legend to load the legend configuration pertinent to
the Project. (if the file is a Berkeley Hills Project, project load GM-Berk)
3. Click on the Compile Map button and select the Map file (unv file) of
your map you exported earlier.
4. The symbols for Stike and Dip should be recreated with the new size.
