Arc GIS Collector and Accuracy of Location and

Arc. GIS Collector and Accuracy of Location and Data 2017 Indiana GIS Day and Conference Joe Madej Seiler Instrument October 24, 2017

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

Poll

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

Uses for Collector • • • Track emergency vehicles during the Boston Marathon Manage large events such as NASCAR Tree Inventory Asset Location Disaster Relief

ESRI Collector for Arc. GIS • Simple toolbar • Common smart device zoom and pan methods • Swipe • Pinch to zoom and Expand • ESRI Background Maps

ESRI Collector for Arc. GIS System Requirements: • Android 4. 2 or later • i. OS 8 or later • Windows 10

Arc. GIS Online Account Requirements • Level 2 Member – Can view, create, and share content • Portal for Arc. GIS 10. 4. 1 is supported

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

A Comparison: Mapping-Grade GNSS Devices vs. Consumer-Grade Smart Devices

HOW DO WE BRIDGE THE GAP TO ACHIEVE HIGHER ACCURACY?

What are my options? • • • Bad Elf GNSS Surveyor, GPS Pro, and GPS Pro+ Dual XGPS 150 A and XGPS 160 Eos Arrow Lite, Arrow 100, Arrow 200, and Arrow Gold Garmin GLO¹ Geneq Sx. Blue II and Sx.

Accuracy vs Precision

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 3 rd Party apps that use the Catalyst position

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.

Catalyst Solution DA 1 Digital Antenna High accuracy GNSS needs to have high quality signal reception from GNSS constellations. Trimble created the DA 1 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.

Customer Story – Collector & Catalyst • City of Centennial, CO and CH 2 M

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.

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 Arc. GIS Online or Portal for Arc. GIS do not support adding domains.

GNSS Metadata

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.

The Aurora Project • Better maps – 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 3 D Data Collection – Vertical Datum Transformations
