3. Today’s agenda ArcGIS Collector Pros and cons of dedicated GNSS units
Trimble Catalyst
How ArcGIS Collector handles metadata associated with data collection

4. Poll Do you currently use Collector?
Do you use high accuracy with Collector?
Ask individually what do you use

5. What is ESRI Collector?
A smart device application used in the field to collect and update spatial data
Puts mapping in the hands of field workers to improve the accuracy of your spatial data
Use your smartphone or tablet to collect in real time or disconnected

6. Uses for Collector Track emergency vehicles during the Boston Marathon
Manage large events such as NASCAR
Tree Inventory
Asset Location
Disaster Relief
Customer in IL who did a tree inventory for a project. Customer then found out that the area was sprayed incorrectly and ended up killing about 75% of the trees, customer came back in and was able to use collector to inventory the trees that were still alive and ones that had perished.
Missouri Botanical Gardens, one of the nation’s oldest botanical institutions uses Collector. From Mapping plant species, to their sprinkler heads. Even have used Collector in Russia and Madagascar to map plant species.

Why are you interested in Collector?

8. ESRI Collector for ArcGIS
System Requirements:
Android 4.2 or later
iOS 8 or later
Windows 10

9. ArcGIS Online Account Requirements
Level 2 Member
Can view, create, and share content
Portal for ArcGIS is supported
Level 1 only has the ability to view maps and not edits them

10. Limitations with Consumer-Grade Smart Devices
Availability (network)
Accuracy level
Assisted GPS (A-GPS)
~ 5-8 m
Wi-Fi Positioning
~ 74 m
Cellular Network Positioning
~ 600 m
Accuracy is relative; your phone can get you to the grocery store, but once you’re there can it get you to the salt or bread?

12. How do we bridge the gap to Achieve higher accuracy?

13. What are my options? Bad Elf GNSS Surveyor, GPS Pro, and GPS Pro+
Dual XGPS150A and XGPS160
Eos Arrow Lite, Arrow 100, Arrow 200, and Arrow Gold
Garmin GLO¹
Geneq SxBlue II and SxBlue III²
Juniper Geode
Leica GG03¹, GG04, and Zeno 20¹
Septentrio Altus NR2 and Altus GeoPod²
Spectra Precision SP60¹ and MobileMapper300¹
Trimble Catalyst
Trimble R1, R2, R8s¹, and R10¹

14. Accuracy vs Precision

15. Catalyst Solution Trimble Catalyst is a solution that includes:
a software GNSS receiver and subscription service that runs on Android smartphones and tablets
a small, lightweight antenna for quality GNSS signal reception
Trimble or 3rd Party apps that use the Catalyst position

16. Catalyst Solution Software GNSS Technology
A software GNSS receiver allows for users to access a range of GNSS accuracy levels on their mobile device, from 1 meter to a few centimeters, on-demand.
Many applications need higher precision than a phone or tablet’s internal GNSS solution can provide, but they don’t need it all the time or can’t justify an up front capital investment. Catalyst is available as a subscription to meet this type of demand.

17. Catalyst Solution DA1 Digital Antenna
High accuracy GNSS needs to have high quality signal reception from GNSS constellations.
Trimble created the DA1 digital antenna to plug directly into Android phones and Tablets to achieve this, while remaining lightweight and compact enough to fit into a backpack or vehicle glove box.

City of Centennial, CO and CH2M

22. GNSS Metadata
Besides geographic coordinates, you might also want to save other GPS metadata associated with a feature such as its accuracy and fix type
This metadata can be valuable to assess data quality and ensure data collection standards have been maintained
You can add GPS metadata fields to a point feature service so Collector can write GPS metadata to the respective fields when editing point features.

23. Publish a Map with GNSS Metadata
Configuring a feature service to store GNSS metadata
Create two domains in your database
Note: Hosted feature layers created in ArcGIS Online or Portal for ArcGIS do not support adding domains.

24. GNSS Metadata

25. Keep in Mind GPS metadata fields are populated on point layers only.
If a point feature is created or updated by long pressing the map instead of using GPS, the GPS metadata fields are cleared.
If a point feature is created or updated and GPS metadata information is not available for the GPS position, the GPS metadata fields are cleared.

26. The Aurora Project Better maps Improved user experience Smarter Forms
Support for vector basemaps
Improved user experience
Better layout and easier to capture accurate data locations
Smarter Forms
Conditional logic, grouping, and ordering of attributes
Enhancements to High Accuracy 3D Data Collection
Vertical Datum Transformations
Target Release is Q2 2018
