###A straight-forward guide to data collection using Terrasync

#Part 1 - In the Field

  1. Open Terrasync
    • Tap on Start
    • Tap on TerraSync
  2. Data Mode
    • In the top left, you will see you are in the ‘Status’ mode, for data acquisition we want to be in ‘Data’ mode.
    • Tap the arrow next to status and select ‘Data’
  3. New file
    • By default, selecting data should bring up ‘Create New Data File’ dialogue and options. If not, click the arrow belonging to the button below ‘Data’ and select ‘New File (T)’
    • A dialogue with options is brought up. Here, the default settings are fine, but it helps to enter a memorable name for the file and to remember the location of where you are saving the file, which is either on the card or on the device (Default / SD-MMC card). A folder can be specified later.
    • Tap ‘Create’
  4. Antenna Height
    • You are prompted to enter the height of the antenna
  5. Type of Geometry – Point, Line, Area
    • Which type of geometry would best represent the feature you are GPS’ing?
    • Once you select, data recording begins.
  6. Recording
    • Data points are being collected now, so either walk if you are representing a line or an area, or stand in place if you are collecting data for a point. For a point, 40 seconds may be required for sufficient accuracy.
  7. Multiple features
    • If you have a single feature to collect you may tap ‘OK’ and then ‘Close’ the file. Otherwise, keep on collecting data for the feature using multiple geometries if needed.
    • Once you have collected enough data, you may tap ‘OK’ and ‘Close’
  8. Multiple Features
    • Once you have acquired data for one feature, another may be created (by selecting again ‘New File) And existing features may be added to (by selecting ‘Existing File’ > choosing the file > selecting ‘Open’)

#Part 2 - At the Computer

  1. Open Terrasync

  2. Enter ‘Data’ Mode

  3. File Manager
    • Below ‘Data’ select ‘File Manager’ (same place you’d see ‘Existing’)
  4. Find data
    • “Choose File Type” should be “Data Files”
    • “Location” is where you saved your files to when you were in the field. If you don’t see your data, change it.
  5. Convert data
    • Select one of the files you created
    • Tap on ‘Options’ in the top right and select ’Write data to Shape’
    • The prompt asks for a location of the file, enter a new name and this will create a unique folder for the file*
    • Prompt says, “The folder __ does not exist. Would you like to create it?” Select ‘Yes’
    • Results should read “Shape conversion complete” you may select “Close”
    • Repeat for other files naming new folders each time to avoid overwriting data.
  6. Transferring data
    • Plug in GPS to computer
    • Open folder where data was saved
    • Copy to desktop
    • Open QGIS
    • Drag and drop data folders into QGIS
    • Select Coordinate Reference System (Usually WGS 84 – EPSG: 4326)

#####*The shapefile that is created is given a generic name based on its geometry e.g. ‘Line_gen.shp’. If saving multiple files to one folder, matching geometries will be overwritten. Unique names for each file will subsequently create unique folders and avoid overwriting data.
