Introduction to the MobileMapper SystemThe MobileMapper system from Thales Navigation is com-posed of two main elements: the MobileMapper receiver and MobileMapper Office software running on a PC-type com-puter.The MobileMapper receiver is a handheld navigation and positioning device that enables you to describe the features being mapped and then format the data so that later it can be uploaded to a GIS. It offers an easy-to-use and easy-to-de-ploy solution for general mapping and for asset manage-1

has three differentfunctions:

It is used to move thecursor in the chosen

direction, from a datafield to another, from anoption in a menu to the

previous or next option. In a highlighted field,

the left/right arrowmoves the cursor back-ward/forward; The up/

6Initialization for First-Time UseMobileMapper will walk you through the process of setting up the receiver for first time use. This procedure is common-ly referred to as Initializing the Receiver. The purpose of this initialization is to provide MobileMapper with a general knowledge of its approximate location.This may seem a little confusing at first as why does a device that is used to compute its position need to know where its at? MobileMapper uses information from the GPS satellites that orbit the Earth and if MobileMapper has an approximate

ization process by press-ing the NAV key anytime

MobileMapper to useand accepting the agree-

GIS Data Logging FunctionsFeature LibrariesFeature libraries contain lists of features that you should be visiting during your field sessions.Features are four types:- Point feature: The geometrical representation of this fea-

ture is a point. Logging this type of feature requires static occupation at the point.

- Line feature: The geometrical representation of this fea-

A feature library is ahierarchical structure

that guides you throughthe description process

so you know you willdescribe thoroughly andquickly each feature you

visit. You will not have toremember what

attributes of each featureyou should record: thefeature library will tell

you!

Logging New GPS/GIS DataPrior to starting logging GIS data, be sure MobileMapper is computing your position when you stand near the first fea-ture you want to log.Press NAV until you display the Map screen. If an arrow is displayed at the center of the Map screen and you can see that your position on the screen is the expected one, then you can start your job. Follow the instructions below to log GIS features.

Entering a job name

The keyboard is fittedwith special keys such as

the CLEAR key to clearthe job name field, the

Shift key to switchbetween upper and

lower-case, the back-space key to delete thelast entered character

and a space key.

Note that a Genericlibrary containing

default features is cre-ated in MobileMapper at

power on. This librarycontains a point feature,

a line feature, an areafeature and a grid fea-

ture. Each of these fea-tures has a single text-

4. Logging and Describing an Area FeatureBasically, you use the same procedure as when you log a line feature, especially regarding the need for defining a logging interval (see 3. above).What is new when you log an area feature is that you can use one of the following two methods:- The first method should be used when contours of

areas are irregular. This method is similar to logging a line area in that you have to move along the con-tour, but you also have to come back to the start point

7. Offsetting a Point FeatureSometimes the feature you want to put on the map is in area of poor GPS reception or is not accessible. This is when you can map the feature using the offset utility. By combining the receivers position with the bearing and distance to the feature, MobileMapper will automatically calculate and record the position of the feature.To input an offset for a point feature, assuming the Fea-ture List screen is now displayed, do the following:- Highlight one of the listed point features available Point Offset screen

9. Logging GIS Data on a Preset Grid NetworkMobileMapper's grid mapping utility is an easy way to automatically set up a series of GPS waypoints to facili-tate the logging of data in an orthogonal grid. This utility assures that you gather measurements made using field sensors such as chemical detectors, depth sounders and magnetometers at an evenly distributed set of locations. This in turn assures the creation in your GIS of contour maps with a prescribed density of data and without any gaps that might force you to return to the field.

To operate the grid map-ping utility, you will need

a measurement device -anything from a depth

sounder to a ruler, yourown sense of smell or

your ability to makevisual observations. You

will also need a compass.

Each grid waypoint is a geographic coordinate you should make every effort to occupy so that the data you record is evenly spaced and complete. However, each grid waypoint is merely an aid for navigating to the ideal location for an observation or measurement. All the data you record is ascribed to the position of the MobileMapper receiver and NOT to the grid way-point.

GPS AccuracyMobileMapper provides better than 10-m autonomous accu-racy around the globe assuming the receiver is tracking five GPS satellites and the PDOP < 4 (which is almost all the time).If you average positions for a point feature for a few minutes, even better accuracy is possible.MobileMapper will warn you if your accuracy of your posi-tions has cropped below the level you selected during Setup

MobileMapper is alsocapable of providing 3-m

Revisiting and Updating Existing GPS/GIS JobsYou can use MobileMapper not only to position and de-scribe new GIS features but also to update information gath-ered previously.

Satellite Status ScreenAlthough the Satellite Status screen is part of the navigation screen sequence, it is not actually a navigation screen. For more details on this screen, refer to page 8.When MobileMapper is computing your position, an addi-tional information appears in the right-upper corner with two possible values: 3D or 2D. 3D means the computed position is 3-dimensional (elevation computed). In 2D (2-dimension-al), elevation is not computed. Mobile Mapper assumes that the last computed or entered elevation is the elevation for all
