Several attribute rows have been added using the Add button (Manhole No., Type, Cover Duty, etc.). Consider the Type attribute, which has been set up as a List to allow the user to pick from drop down menu when surveying (Circle, Square, Triangle, Rectangle). All attribute information can be saved as *.csv files which can be reloaded or loaded into other feature library / projects.

20 17

21 18 Once the attributes have been assigned the feature library should be resaved. Select 'FILE > Save feature file' Enter Name 3 Transferring Files From SCC and CAD To PocketDTM The following explores several options of transferring files to PocketDTM: 3.1 Transferring SCC Model To PocketDTM As Background Mapping Prior to exporting model it is necessary: To transfer SCC library to PocketDTM (as outlined in Transferring SCC Feature Library to PocketDTM 14 ) to PocketDTM, to ensure that when the model is drawn within PocketDTM features are represented correctly Within SCC, open Project and Model Step 1: Export SCC Text File From within the model, select 'FILE > Export Model > SCC Text File' Select 'Ok'to export file to project folder The file should be copied and pasted onto Storage Card Step 2: Importing Background Mapping to PocketDTM Begin a new job as outline in previous steps Select feature library suitable for the data within 'FILE > General Options' Go to the Plan View, select 'FILE > Import /Export > Import survey from SCC' Select 'No'to Connect to SCC prompt (as file is already transferred to card)

22 19 Pick '16095.Model.sio'from the Open dialog and press 'Open' The background map is imported into the Plan View Sample Image of Models Transferred from SCC to PocketDTM!" 3.2 Transferring Client DXF to PocketDTM There are a number of steps to importing a dxf to PocketDTM. Step 1: Import DXF into SCC Two options are available when SCC is opened, either open an existing project or start a new project. When using SCC for the first time, it is necessary to start a new project. Starting the Software Double click the SCC Icon On first entry to the software, or if there is no active projects, the following dialog will be shown on screen

23 20 Select 'Cancel' From the Main Menu Bar within SCC, select FILE >New Project Enter in a Project/Job name Select a Project Template from the list / specific utility survey template Select OK The project template contains all the feature coding, layering, string labelling, modelling, symbology and annotation standards that will be applied to the project. The project itself consists of a spreadsheet containing the control stations used in the project, along with a feature library spreadsheet. Importing DXF Select 'FILE > Model > DWG / DXF File' Using the Pick button select dxf

24 21 Select Layer to Feature Mapping>> This option allows the user to map layer present in the dxf file with feature in the SCC Feature Library Select 'Import layer map from DXF' The table should be examined so that layers from the dxf are mapped to the correct feature code from the SCC library. Often layers which are not needed in the model are mapped to an IGNORE feature. This IGNORE feature would be set up in the users library to have a DTM status of Ignore and therefore not modelled. Select OK within the DWG/DXF Input Layer to feature map Dialog Select OK within the Import DWG/DXF file Dialog Set the Plot Scale

25 22 Pick 'Create the Model and triangulation Press 'Ok'to model attribute dialog Save Model Step 2: Export SCC Text File From within the model, select 'FILE > Export Model > SCC Text File' Select 'Ok'to export file to project folder The file should be copied and pasted onto Storage Card Step 3: Importing Background Mapping to PocketDTM Begin a new job as outline in previous steps Select feature library suitable for the data within 'FILE > General Options' Go to the Plan View, select 'FILE > Import /Export > Import survey from SCC' Select 'No'to Connect to SCC prompt (as file is already transferred to card) Pick 'Sample.Model.sio'from the Open dialog and press 'Open' The background map is imported into the Plan View Sample Images of Client Data Transferred from SCC to PocketDTM!"

Additional Manhole features have surveyed using tape and distance measurements which will be added to the main survey as follows: Open Job within PocketDTM Pick Manhole feature from drop down feature menu Select 'EDIT > Intersection by Distance' Press '>>'button alongside Point A Select 'Pick from screen'within Pick A Point dialog

28 25 Select point on screen using stylus pen PocketDTM will prompt with the selected point and press 'OK'to confirm In the same manner pick Point B Press 'Ok'to confirm point

29 26 In this instance, it is know that the new feature point is 6m to A and 4m to B Set intersection to Pick to allow interaction on screen Moving the stylus whilst keeping contact with the screen either point left or right of line can be set Tap screen with the stylus to confirm new point Depending on how a feature is set up in the library, additional information may be prompted as shown below If there is no deviation from the settings in the feature library simply select 'OK' Note the library can be set up to always use defaults and therefore not prompt for additional information

30 Sketching In Points On Screen Using The Pen Consider that a topographic survey has been completed. Additional service information has been obtain and therefore added as follows: Open Job within PocketDTM Pick USTE Underground Survey feature from drop down feature menu Pick 'Active Elevation'button from the Toolbar If required enter height Press 'OK'

31 28 Turn on Snap controls 'VIEW > Snap Controls' Press stylus on first point A for example, then B, C, D etc to form required line

32 29 Note: While string information is being sketched the user can add additional information such as line connection tags of curve, straight, arc quickly by using keyboard shortcuts as shown in Keyboard Shortcuts Surveying Points Using Taped Right Angle Offsets Consider that a topographic survey has been completed. Additional Manhole features have surveyed using measurements taped from a reference line which will be added to the main survey as follows: Open Job within PocketDTM Pick PAV feature from drop down feature menu Select 'EDIT > Tape Measurement' Press '>>'button alongside Point A Select 'Pick from screen'within Pick A Point dialog

33 30 Select point on screen using stylus pen PocketDTM will prompt with the selected point and press 'OK'to confirm In the same manner pick Point B Enter the known offset from the baseline C point 67 to C point 68

34 31 Press Store point In the same way, a string can be generated from the baseline and the reference line updated (select 'Use last two survey obs as base line') as new points are entered, as shown below: 4.4 Collection Of Attribute Information As shown in Setting Up Extra Database Fields Against Specific Features 15, GIS information can be set up against various features within the library. This options can be used during initial capture of topographic information or as a additional task once the survey has been completed.

35 Entering Attribute Information As Part of Survey When surveying with PocketDTM with a feature that has attribute information set up in the library, once the observation has been taken the attribute information dialog can be filled in. As shown in Setting Up Extra Database Fields Against Specific Features Within PocketDTM Library 15, lists can be set up and default values assigned depending on requirements; Entering Additional Attribute Information After Initial Survey Once a survey has been completed additional attribute information can be added. From the Plan view, select 'EDIT > Query & Edit' Pick point with stylus Select 'GIS Attributes for selected point'

36 33 The user then has access to the GIS tables set up against that feature in the feature library 5 Downloading to SCC Export from PocketDTM Select 'FILE > Import / Export > Export to SCC' Select 'No'to Connect to Comms At this point, the file is exported as a.sio file onto the storage card (\PocketDTM) Exit the Job and shut off unit Take the card out of unit and transfer to PC card reader

37 34 Copy the file to the PC SCC Open SCC From the Main Menu Bar within SCC, select FILE >New Project Enter in a Project/Job name Select a Project Template from the list Ideally this template would correspond to the feature library used in PocketDTM Select OK Select 'FILE > Download Survey' Pick 'PocketDTM'as the Survey data logger drop down menu Set 'Detail Topography'as the 'Data Type' Set 'Disk'as the 'Data logger input device' Select 'OK' Pick file and press 'Open' The file is download as a dataset for analysis and then can be modelled Generating Reports and CAD Drawing from Survey SCC produces high quality reports from all SCC documents using the industry acclaimed Crystal reports engine. These reports can include data, charts, bitmaps and other rich content, and can be output to printers, PDF, Excel, HTML and Word files. Sample reports are available within the SCC directory. These templates can be used to regenerate project specific report data directly from SCC. The Crystal reports also have the advantages that they allow the report layout to be readily changed without affecting the content, they allow automatic highlighting of out of spec values such that they can be easily picked up by anyone reading the report, and they can be readily exported to a range of formats including Word, PDF, Excel and HTML. Note that while creation of new report formats requires a Crystal reports license, creation, viewing, printing and export of reports is included within the SCC license. To view a report, click 'FILE > Reports'and select sample report.
