Section 1 Document Information This document includes the systems integration information and implementation in order to facilitate the flow of

data between field collected data managed by ArcGIS Online externally hosted by Esri, as well as image

integration and storage. Generally, Systems integration is defined as facilitating the communication of

information between two (2) or more different applications, systems, platforms and/or products. This document

includes the details for the following types of components in an effort to provide sufficient to identify the method

of information flow among systems:

• Web service integrations

• Data integrations

• Mobile field data integrations

However, this document does not include information for the following components as they are considered

Universal across most applications:

• Active directory because it is done to provide security, not to achieve specific reusable functionality

• Database connections made by an application to perform CRUD transactional operations as these

connections do not qualify as integration efforts among different systems

1.1 Information

The Pavement Management and Materials programs require a technology based solution for agency-wide data

collection and management system whose primary function is to expedite and streamline the process of collection,

storage and reporting on pavement core sample data.

In order to accomplish the above articulated need, VDOT requires an agency-wide data collection and

management system that includes the following functionality:

• Coring Data Management Services

o tracking of pavement core sample data (core location and business data)

o share pavement core sample data across the agency

o ability to store and search image files

o store core sample location data on GIS

o ability to define extent along a route and link report files

o utilize mobile technologies for data collection

o capacity to export business data to support District information needs (e.g. pavement coring

report generation)

• Exporting Capacity

o capacity to select from map and export the associated data

o access to image files and reports

o capacity to generate a map output of current extent

• User Interface

o provide a visual indication of required data elements in online screens

o provide a save option for data editing

• System Interfaces

o Pavement Management System

o Azure Cloud

• System Access and Security

o Integrated technical safeguards to ensure a level of privacy and security, including

Administrator controlled user name and password access

Administrator controlled user level read, write, edit and delete capabilities

o Capable of supporting 50 concurrent users (collection at multiple paving locations across

multiple Districts, with simultaneous data entry/review in office)

o Capable of supporting single sign-on

Section 2 Integration Conceptual View

2.1 Diagram and Description The Pavement Core Sample data will reside in ArcGIS Online, and will provide a feature service for field collection of data

through Survey123 for ArcGIS – which includes attribution and photographs – and will be accessible from the PMS front-

end. Tools will provide the ability to export data from an interactive map to CSV.

Pavement Coring Report Location data:

• Office Materials Users will access the GIS pavement core records and select and export data to manipulate and use for analysis

• Office Materials Users will manually create Pavement Coring Reports, and then manually define a start and end point along a route, and attach the coring report to the location definition

• An automated process will create a route segment as a GIS line feature, using the user-created start and end points and the LRS Route dataset

• An automated process will export the coring reports to CSV every morning at 10AM

• On demand import tool will be run by Maintenance Division admin to import CSV into PMS Staging Tables and finally PMS Tables through PMS front-end. Data will remain in GIS for viewing, but will not be pushed again after moving to PMS.

Information about the new PMS table needed to support the PMS Report Location:

• Table will contain at minimum the basic information listed below: o District o County Maintenance Jurisdiction o Report Date o Link to the report itself (file path in cloud-based file storage solution) o Location Information (as stored in PMS SETUP LOC IDENT table)

• Table may be expanded to include other information deemed useful

viewing and editing of data via in office applications

Section 3 Logical View

3.1 Diagram and Description For pavement core workflow, the process is initiated through mobile field collection which then writes this collected

data to ArcGIS Online via a published feature service, this includes the collection of image data. The Materials user

accesses the field collected data via a Web Mapping App, exports data to create a report, defines a Report Start and End

point in GIS data, and attaches the report to the Report Start point. A scheduled python script creates GIS line features

from the Start and End points and the LRS data (visualizing the extent of the report along a route). A PMS admin user

can run import tools on demand to import data from GIS to PMS through the PMS front-end.

3.3.1 Pavement Core Sample: Update RNS Intersection and RNS Route Name (Figure 1-a)

Scheduled process (Python) that updates the RNS Intersection and RNS Route Name attributes of Pavement Core Points.

Field data collection users will not be able to manually enter these attributes. Instead, users will populate attribute

fields to indicate the Route associated with the data (including Route Prefix, Route Number, and Route Suffix), and the

update process will take that information as well as the spatial location of the point and match that against the LRS to

Scheduled process (Python) that creates a GIS line feature as a segment of an LRS route, using the user-defined Report

Start and Report End points (and attribution on the data, including Route Prefix, Route Number, and Route Suffix) and

the LRS dataset. This tool will create Reference lines for newly created Report Start and Report End points, as well as

update any lines if the Start and End points have been modified.
