  2. GIS POST-PROCESSING • PREPARATION • Power, USB/PC cable, Active Sync Connection • Install MobileMapper Today on MobileMapper 6 • ftp://ftp.ashtech.com/Mobile Mapping/MobileMapper 6/Software/MobileMapper Software/MobileMapper Today/MobileMapper Today.zip • File on FTP site is zipped and must be extracted prior to installation • Execute MobileMapperTodaySetup.exe file on PC while MobileMapper 6 is connected via ActiveSync • MobileMapper Today is installed on to PC and then on to the MobileMapper 6 • Install MobileMapper Office on PC • ftp://ftp.ashtech.com/Mobile Mapping/MobileMapper 6/Software/MobileMapper Software/MobileMapper Software.zip • File on FTP site is zipped and must be extracted prior to installation • Execute Setup.exe file on PC to install MobileMapper Office to PC

  3. GIS POST-PROCESSING • PREPARATION (Continued) • Install MobileMapper Field on MobileMapper 6 • ftp://ftp.ashtech.com/Mobile Mapping/MobileMapper 6/Software/MobileMapper Software/MobileMapper Software.zip • File on FTP site is zipped and must be extracted prior to installation • Execute Setup.exe file on PC to install software while MobileMapper 6 is connected via ActiveSync and install the MobileMapper Field software to MobileMapper 6. MobileMapper Field is installed to the PC and then on to the MobileMapper 6 • Versions • MobileMapper Today (MobileMapper 6) – V 1.0.0.15 • MobileMapper Office (PC) – V 1.0.1.3 • MobileMapper Field (MobileMapper 6) – V 1.00 • GNSS Toolbox (MobileMapper 6) – V 1.00 • Installed as part of MobileMapper Field

  4. GIS POST-PROCESSING • PREPARATION (Continued) • Licensing • MobileMapper Office (PC) requires no license • MobileMapper Field (MobileMapper 6) must be licensed with activation code • Program will not open without license • Post-processing for MobileMapper Field must be licensed with activation code • Code requested when selecting “Record raw data for post-processing” box inside the “Recording” tab under the “Options” dialogue boxes

  5. GIS POST-PROCESSING • OUTDOOR FUNCTIONALITY TESTS • Outdoors cannot be simulated using GNSS Toolbox • Satellites tracking • Raw data logging – Has this option been licensed and is there sufficient memory? • Ground truth against known data – Does the computed position appear correct?

  6. GIS POST-PROCESSING • DATA COLLECTION • Advice • Software activation codes require the user to put the MobileMapper 6 into suspend mode or the code will be lost. With that task done once, it can be powered on and off without losing the code. • Use MobileMapper Today to set the clock every time it is turned on to ensure that the clock is set properly before using MobileMapper Field. It is the first clue that the MobileMapper 6 is ready for work. Manually setting the clock does not ensure that the clock is set properly. • Good PDOP does not ensure good accuracy. Consider the quality of the GPS signal. One customer who complained about accuracy sent photos showing the receivers lying on the ground. Signals bouncing off the ground are multipath.

  7. GIS POST-PROCESSING • DATA COLLECTION (Continued) • Advice (Continued) • Do not expect CORS reference data on the same day of recording. • Accuracy has as much to do with the 10 minutes before and after the feature was recorded as it does the ten seconds spent recording a point feature. • Common mistakes and things you should NOT do: • Raw data recording begins before the clock is set or before there is a stable DGPS solution. • Raw data recording is halted between feature mapping resulting in dozens of tiny raw data files, none of which will process properly. • Raw data recording of such short duration that it will not process. Many of these contain ephemeris files too tiny to have recorded the current ephemeris. Good rule of thumb is that a file less than 20 minutes long is wasted effort. • Feature mapping that begins within seconds of starting the raw data recording. • Put receiver in pocket while walking between features to be logged..

  8. GIS POST-PROCESSING • DATA COLLECTION (Continued) • Orient GPS unit against the local sky • Ensure satellite tracking • Ensure DGPS solution if in an SBAS coverage area • MobileMapper Field basics • Main screen • Position icon • DOP • Solution type • Easting/Northing • Scale • Menu • Log

  9. GIS POST-PROCESSING • DATA COLLECTION (Continued) • MobileMapper Field basics (Continued) • Menu • Pause/Resume • Stop • Layers • Job • Options • Status • Exit (not the “X”)

  10. GIS POST-PROCESSING • DATA COLLECTION (Continued) • Create New Job

  11. GIS POST-PROCESSING • DATA COLLECTION (Continued) • Create New Layer • Point Feature

  12. GIS POST-PROCESSING • DATA COLLECTION (Continued) • Create New Layer (Continued) • Point Feature (Continued)

  13. GIS POST-PROCESSING • DATA COLLECTION (Continued) • Add another layer • Line Feature

  14. GIS POST-PROCESSING • DATA COLLECTION (Continued) • Add another layer (Continued) • Line Feature (Continued)

  15. GIS POST-PROCESSING • DATA COLLECTION (Continued) • Add another layer (Continued) • Polygon Features

  16. GIS POST-PROCESSING • Data Collection (Continued) • Turn on raw data recording • Menu / Options • Choose memory location • Check box and then OK • Wait a few minutes in clear view of the sky before recording features.

  17. GIS POST-PROCESSING • Data Collection (Continued) • Collect (Log) four points describing a rectangle

  18. GIS POST-PROCESSING • Data Collection (Continued) • Collect (Log) four points describing a rectangle (Continued)

  19. GIS POST-PROCESSING • Data Collection (Continued) • Collect (Log) four lines describing the same rectangle

  20. GIS POST-PROCESSING • Data Collection (Continued) • Collect (Log) a polygon describing the same rectangle

  21. GIS POST-PROCESSING • Data Collection (Continued) • Turn off raw data recording • Wait a few minutes after recording last feature • Menu / Options • Deselect check box and then OK

  22. GIS POST-PROCESSING • Post-Processing • Submit raw data files to Joe Sass for pre-analysis • jsass@ashtech.com • All shape files (*.shp, *.prj, *.shx, *.dbf) in targeted directory • GPS Raw Data in its own folder (*.grw and *.crw) • Reference data – Preferably 1 second data rate • Rinex data from local CORS • “G” file from ProMark/ProFlex 500 base station • Create new or open existing Map project in MobileMapper Office • Activate collected SHP files from the data collector • Import Rover raw data from the data collector • Import Reference raw data from file or internet • Enter correct reference station position • Post-process data • Export or transfer data to destination software
