W atching the bars appear and turn solid on the screen, you can progressively see the unit lock onto satellites. Once the first pos iti on fix has b een computed, the Map screen is au[...]

9 GIS Dat a Logging Functions Feature Librar ies Feature libraries contain lists of featu res that you should b e visitin g during your field sess ions. Features are four types: - Point feature: The geo m etrical representation of this fea- ture is a point. Logging this type of feature requires static occupatio n at the point. - Line feature: The g[...]

10 Logging New G PS/GIS Data Prior to starting logging GIS da ta, be sure MobileMapper is computin g your position w hen you s tand near the first fea- ture yo u want to log. Press NA V until you display the Map screen. If an arrow is displayed at the center of the Map screen and y ou can see that your position on the screen is the expected one, th[...]

11 The Logging screen is now displayed where you can see the list of attributes pertaining to this feature. Y ou will now enter the “Description” phase of the feature - W ith the first attribute highlighted, press ENTER and choose the right attribute value descr ibing the feature near you an d press ENTER. This t akes y ou back to the Logging s[...]

12 After highlighting a line feat ure from the Feature List screen (for example a road) and press ing ENTER, MobileMapper s tarts logging GPS positions from t he position where you are. Th e firs t time you log a lin e area, and then every t ime you think this is necessary: - P res s ME NU, hi ghl igh t Logging I nterval and press ENTER. T wo optio[...]

13 4. Loggin g and Describin g an Area Feature Basically , you use the same procedure as when you log a line feature, esp ecially regarding the n eed for defining a logging interval (see 3. abov e). What is new when yo u log an area featur e is that you can use one o f the following tw o methods: - The first meth od sh ould be used when cont ours o[...]

14 By the time y ou are done with the description, MobileMapper will probably have logged th e GPS position o f the corner . - N ow , pr ess MENU , high lig ht Pau se <feature name> and press ENTER. This pauses the logging of the feature. - Move to the next corner of the area where yo u can now resume logging the feature - T o do thi s, pres [...]

15 6. Nes ting a Featu re When you are lo gging GPS positions to a feature, you may fin d another feature that you also w ant to log. Rather than log the entire feature and come back to record this other feature, you can simp l y pause the fea- ture bein g logged, log the other feature, close it and resume logging the first feature. Logging o ne fe[...]

16 7. Of fset tin g a Poi nt F eat ure Sometimes the feature you wan t to put on t he map is in area of poor GPS reception or is not accessible. This is when you can map th e feature using the offset utility . By combining the receiv er ’ s posi tio n with the bearing and distance to the feature, MobileMapper will automatically calculate and reco[...]

17 8. Offs etting a Line or A r ea Featur e For the same reasons as a point feature (see previous page), you may need to use the offset utility to map a line or area feature. B y combining t he receiver’ s position with the direction and the distance to the feature, MobileMapper will automatically calculate and record the location of th e feature[...]

18 9. Log ging GI S Da ta on a P reset Grid N etw ork MobileMapper's grid mapping uti l ity is an easy way to automatically set up a series o f GPS waypoints to facili- tate the logging of data in an orthogonal grid. This utility assures that you gathe r measurements made using field sensors such as chem ical detectors, d epth sounders and mag[...]

19 - Record an observation or measur em ent : W ith the OK field highl ighted, just press ENTER. This takes you to the Loggin g screen that indicates that you have begun logging data to t he feature and that the receiver is ready to lo g the feature's attributes. Remember that you remain stationary for all point features. Describe the feature [...]

20 Each grid way point is a geographi c coordi nate you should make every effort to occupy so that the d at a you record is evenly spaced and complete. However , each grid waypoint is merely an aid for n avigating to the ideal location for an ob servation or measurement. All the data you record is ascribed to the position of the MobileMapper receiv[...]

21 In the open job, do the following: - On the Feature List scr een, select t he grid featur e and press ENTER. On the Grid Setup screen that is now displayed, set the parameters lis ted below . Spacing : Distance between any two con s ecutive way- points in any row or column (default: 50 meters or 100 feet , dependin g on the uni ts used) Columns [...]

22 GPS Accuracy MobileMapper pr ovides better than 10-m au t onomous accu- racy around the globe assuming the receiver is t racking five GPS satellites and the PDOP < 4 (which is almost all the time). If you average p o sitions for a point feature for a few minutes, even better accuracy is poss ible. MobileMapper will w arn you if your accuracy [...]

23 Revisiting and Upd ating Existi ng GPS/GIS Jobs Y ou can use Mobil eMap per no t onl y to po sit ion an d de - scribe new GIS features but also to update in formation gat h- ered previously . This is particularly useful when collecting data on things that change over time: streetligh t bulbs burn out, new ro ads are added to housi ng development[...]

87 However , line and area featur es diff er from grid features in two important ways: - The positions making up line and area fea tures mark the locations of real things like roads, lakes, etc. But the points making up a g rid feature are imaginar y target locations that you navigate to. - The attributes y ou record fo r a road or a lake pertain e[...]

88 Name: Feature names like “pole,” “road” or “lake” make it easy to id entify the geomet ry of point line and area fea- tures. This is not so easy with grid features. Y ou might find it helpful to insert the word “grid” into the name of grid features. However , ther e is a 10-character limit to the name length so you may p refer to[...]

89 When changing fro m t he default 50 meters, keep in mind that the selected v alue will determine the density of mea- surements. If this number is less than 5 meters or so, there is no point in using a Grid f eat ure. Simply walk around and take samples by visually estimating the require d density . If you increase th e spacing, be sure the spaci[...]

90 Using the W aypoint/Route Editor Introduc tion The W aypoint/Route Editor allows you to easily create a list of wayp oints that might b e useful for the field operator when she/he is perfo rming a GIS job.

94 Background Map s Introduc tion Backgroun d maps are design ed to provide useful details on working areas. Field operators mi ght like to see these d etails on their hand held screens as th ey progress in th eir jobs so that they can mor e easily go to the places they h ave to visit. Backgroun d maps are for viewin g only . Y ou cannot edit them [...]

95 A backgrou nd map gene rally consis t s of a ba se map, plus ad- ditional details that you can for example import from your GIS system. Thus, a background map is a st ack of several layers, b ut as oppos ed to layers in a job f i le, which you can select on the Map Display area, the layers compo s ing a back- ground map result in a single, mer g[...]

96 Creating a New Background Map Project - On the menu bar , select T ools an d then Ba ckground Map . This opens the Background Map s window - Click on the Cr eate New ... button.

97 Adding Layers to a Background Map Pr oject (Cont inued from previous p aragra ph.) Y o u can add as many layers as necessary to b u ild a back- grou nd ma p. Lay ers may be SH P file s or MIF f iles . For example you co uld export to SHP ou MIF the features of a completed job an d then add them as layers to create a back- ground map. In this cas[...]

98 Changing the Order of Layer s When you build the backgr ound map, the first layer you placed in the table will be brought to the front, and the last one will be sent to the back. Intermediate layers will occupy intermediate positions in the layer stack. If one of your layers contai ns area features , it is important that this layer be placed at [...]

99 Changing the Visual Aspect of Layers Y ou can customize each layer by clicking on the corres p ond- ing left most cell in the table . This opens a dialog box in which you can ch oose the aspect you want for th e layer when the background map is built up later . As you wi ll probably notice, the available options are much similar to those avail- [...]
