Authorized Service Center
Intro
• Who – Bluefield Sanitary Board, Steve Duffy, Engineering Manager
• Why - SSES Sanitary Sewer Evaluation Study completed by Thrasher
Engineering impetus for overhauling GIS
• CAD converted to GIS LGIM
• Setup of smoke test dataset in GIS
• CCTV processor module implemented and video data linked
• What – After updating GIS BSB sought to improve the quality of the
GIS data with high accuracy positions and increase access throughout
the organization with cloud hosted technologies for both field users
and upper management.
Data Collection - Criteria
• Utilize existing mobile devices (Android) tablet/phones.
• Simple easy to use interface
• Desire for sub-meter to sub-foot accurate data locations.
• Access to free WVDOT VRS network and reasonable coverage of cellular
network in the BSB territory.
• Ability to both collect new features and update existing datasets.
• Ability to link data directly to the Esri LGIM
• Prefer to wirelessly sync data.
Hardware & Software
• Android tablet
• Trimble TerraFlex Advanced Subscription
• Update as well as collect new data
• Access VRS for real-time sub-foot accuracies in the field.
• Trimble TerraFlex for ArcGIS Plug-In
• Forms for data collection generated from Esri LGIM schema to include domains and
sub-types.
• Need to check-out existing assets directly from ArcGIS as a task to be updated
• Add GNSS Metadata fields to Geodatabase during project setup.
• Trimble R2 – Sub-foot GNSS Receiver
• Increased accuracy with limited budget (over 7x)
• Can share GNSS receiver with different users/different mobile devices.
Trimble R2
Trimble R2 GNSS Receiver
• Released in September 2015
• Sub-foot positioning accuracy
• Compatible with VRS and RTX networks for
real-time correction
• Connect to devices with Bluetooth or USB
• Configurable NMEA and GSOF data outputs

New Features
• TerraFlex Plugin for Esri ArcMap:
• Include standalone geodatabase tables in a
project and optionally transfer geometry back to
fields in the table
• Create auto-fields from the add-in
• Upload features without having to directly assign
them to a task
• Set accuracy thresholds

Check-in New/Updated data
How This Benefits You
• Productivity:
• Pause and collect for more efficient
field data collection
• Collect with more field device
configurations
• Edit more geometry types, rather
than having to recapture an entire
line or area geometry from scratch
• Integrity:
• Keeping your TerraFlex templates
tightly synced with your ArcMap
schemas
How This Benefits You
• Flexibility
• Option to use Esri geodatabase tables. Tables may be the method data is synced
with other external databases that do not readily accept spatial references
• Add TerraFlex auto-fields on the fly. Uneditable meta-data capture including:
• Collected by
• Device type
• Device ID
• Correction status – method of GNSS correction
• Correction source – SBAS, VRS, etc.
• Creation date and time
• Update date and time
• Estimated accuracy
• Geometry capture type – GNSS or digitized
• PDOP/HDOP – traditional GNSS accuracy parameters

Office Processes
• CCTV processing
• Tap Sheet import
CCTV & Televised Mains
• CCTV camera & inspection activities being performed
throughout the system
• Using Esri’s CCTV Processor to ingest & process incoming data
• Photos stored as Feature Attachments
Goals:
• Share CCTV data via ArcGIS Online
• Export photos from attachment tables
• Create local and web-accessible links to photo video files
Exporting Feature Attachments…

Feature Attachment Export - ArcToolbox
Feature Attachment Export - Script
Open in NP++
Feature Attachment Export – ArcGIS Online
Tap Sheets
• Historic system documents
• Valuable information, often not
reflected in the GIS data
• Goal: make available through GIS
Tap Sheets – Document Organization
• Documents organized by Street & Block Number
Tap Sheets – Block Points
• ‘Block Points’ created from available addressing information
Tap Sheets – Database Schema
Tap Sheets- Script
Open in NP++
Tap Sheets- Collector for ArcGIS
Field Operations
• Additional ArcGIS Online-only workflows have been implemented
• Sanitary & Stormwater Action Item Inventory
• Sanitary Manhole Inspections
• Map Change Request
Summary
• Utilize existing best practices; standard data models & capture GPS
metadata.
• Review fit of field requirements for field environments.
• GPS and GIS don’t work alone consider end value of data first.
• The best solution is often not achievable with one product but an
integration of hardware and software from various vendors.
• Web hosted solutions bring greater access to GIS data at a price many
organizations can afford.
