Tech Tip


SETTING UP ESRI'S COLLECTOR FOR HIGH-ACCURACY DATA COLLECTION

Requirements:

  • High-Accuracy receiver such as Trimble R2
  • Mobile Device
    • iOS 9 or newer
    • Windows 10
    • Android 5.1.1 or newer
  • ArcGIS online account with edit-enabled web map
  • Esri's Collector App (app store-platform dependent)
  • Trimble GNSS Status app (app store-platform dependent)
  • VRS subscription account
  • Internect connection

Steps:

1. Establish Bluetooth connection with receiver

2. Establish connection with Trimble GNSS Status app

3. Configure R2 for real-time connections other than SBAS using the GNSS Status app.*See Configuring R1 with Collector for info on using SBAS (Duncan-Parnell Success Center)

4. Configure R2 to use VRS real-time corrections
• Tap the menu button and choose "Real-time Config":

• From the Real-time Config screen tap "Edit" at the top right of the screen:



• Tap the "Primary Source Type" field. Choose Internet from the list of correction types. *In most cases you must have a subscription to use any real-time correction methods other than SBAS.For high-accuracy a VRS or Trimble RTK subscription is required. Inquire with your Trimble dealer for more information:

• Tap "Save". Then tap the menu button and return to the Home Screen
• Once the GNSS Status app is connected to the R2 receiver and the VRS service is in use, you will see "NTRIP" ("RTK" is using Trimble service) populated in the bottom right-hand circle and the Estimated Accuracy will drop to <6 inches:

5. Configure the Location Provider in Collector for ArcGIS
• From the Collector home page, tap the 3 dots to access the settings
• Click on the Location Provider to change it from the internal GPS to the external receiver:


6. Set up the Location Profile for high-accuracy collection
• From the settings dialog, click on Location Profile
• Click (+) Add Profile:


• Select the correction service's coordinate system. Most services use GCS NAD 1983 2011. Use the filter and type "NAD 1983" to narrow options
Select the coordinate system used by your map. This is referring to the coordinate system of the webmap, not the mxd the data was published from. ArcGIS Online uses WGS 194 Web Mercator for hosted web services. Type "wgs 1984 web" to filter results. There are two, either will for for 10.x users
Specify area for data collection. Zoom into work area to decrease the number of available datum transformations - more in the next step. Click Next
• Select the datum transformation. For most users in the Continental US and Alaska, use "WGS_1984_(ITRF00)_To_NAD_1983_2011" :


• Click Done
• Enter a name for the profile. Name it something like correction coordinate system to map coordinate system so that you can easily identify it later. For the above example, name it "2011 to webmercator":


• Click OK
• Once added, click on the new Location Profile to use for high-accuracy collection

7. Return to the Home Screen and resume working
