The Basics

What is the Data Interoperability Extension?All About Moving Data From A to B

• What formats?

• From A,B,C… to D,E,F… at once?

• Local data or web too?

• What can I do on the way?

• Is this part of Geoprocessing?

• Can I automate this on a schedule?

• Does it understand OAuth2?

• Do I have to code?

• Can I work with FME?

Where is the Data Interoperability Extension?ArcGIS Desktop, ArcGIS Enterprise

• Desktop means ArcGIS Pro, ArcMap, ArcCatalog…

• Licensed like any other extension

- Named user, concurrent, single user

- Don’t forget to install it

• Analysis Tools includes Quick Tools

• Author Spatial ETL workspaces

- Directly from the ribbon

- Within a toolbox

• Import a Spatial ETL or FME source FMW file

How can I use the Data Interoperability Extension?

• Traditionally three workflows – Direct Read, Quick Conversion, Spatial ETL

• Web GIS and the API economy adds the requirement for Services

Emergent themes: Connectivity, Transformation, Automation

How Do We See People Using Data Interoperability?Top Use Cases

• Migration

- Adoption of ArcGIS, Working with ArcGIS

• Connection

- Apps with an API

• Collaboration

- Generate data in a business-friendly format

• Validation

- Feature-Level Business Rule Enforcement

• Detection

- Cross-Format Feature Interaction

• Synchronization

- Feature Services and other repositories

Formats and Repositories

• Formats are data structure

• Web formats are semantic

- JSON

- XML

• Data can be/go anywhere

- Downloaded on demand

- Uploaded to Server, Cloud

- Not tied to ArcGIS Project Catalog

• Increasingly network accessed

• Decreasingly file system

File, Connection, Web – pick any three

APIs too

Direct Format ReadDesktop 10.x Experience

• ArcGIS is Geo-Relational

- Feature classes are database tables with an ObjectID and a geometry column

- Tables have ObjectID but no geometry

• Some file formats can be automatically interpreted this way

- Recognized by file extension (.gml, .geojson, .kml, .gpx, .xlsx, .osm, .xyz….)

- Default behavior assumed

• Many data sources are out of scope for Direct Read

- Not visible in the Catalog

- Interpretation is required

- Custom formats are an option (advanced topic)

• Not feasible in a fully Web GIS

Quick Import and Quick Export

• Easy Button

• When you need data to participate in:

- Editing

- Geodatabase behavior

• Quick Import

- Writes to Geodatabase, Create or Overwrite

- Default Schema

- Postprocessing often required

- In Modelbuilder the Select Data tool accesses feature classes

- Project or Define Projection

• Quick Export

- Writes Any Format (300+ available)

- Default Schema

Multiple FormatsSometimes intermediate data is read or written

• Read Many

• SQL Interact Many

• Spatial Interact Many

• Expression Interact Many

• Write Many

What’s a Transformer?Extract Transform Load

• Transformers are analogous to a geoprocessing tool in ModelBuilder

- Can be grouped, nested, iterated

• Have input and output port(s)

• May read & write filesystem, database, web

• May operate per feature, per group of features or whole dataset

• May operate on attributes and/or geometry

• May operate with parallel concurrency

Transformer Basics

Bruce (but I bet Dale chimes in)

Authoring Workspaces

Environment & Options

• FME 2018.0.0.2 Engine

- 300+ Formats

- Feature Caching

- FME Compatible FMW Source

- Database Connections

- Web Connections

- FME Hub Connectivity

• Python Compatibility

- Inherit Pro’s Conda Environment

- Custom Interpreter can be set

Data Interoperability

We could argue all day about how many formats…

What’s FME Hub?In-App Function Download

• Community Platform

- Transformers (in Transformer Gallery)

- Formats

- Templates

- Web Connections

• Search by keyword

• In-App Browsing

- https://hub.safe.com

Custom Transformers

Assemble transformers into logical unit

Declutters the workspace

Looping mechanism

Like grouping in Modelbuilder HTTP Pagination Example

• Get Background Maps

• Work With Feature Services

- Existing Feature Service

- Create New Feature Service

- Add, Delete Features

- Update Features

- Truncate Services

• Coming in 2019

- ArcGISOnlineConnector

- File upload & download

Integrating ETL Tools and Geoprocessing

• ArcPy access is the same as core geoprocessing

- ImportToolbox

- arcpy.<toolname>_<alias> or arcpy.<alias>.<toolname>

• Wrap ETL tools in ModelBuilder

- Interaction with GP environment and processes

• ETL tool parameters may not match geoprocessing parameter types

- Cast the type in ModelBuilder

A Tool is a Tool

Automation within Geoprocessing
