DISCLAIMER

When it comes to FME…I, Scott McQuarrie, am not a guru, expert, especially

skilled individual or any other term that describes anything more than a barely

adequately equipped individual. The information portrayed in this presentation is

pretty much what I learned while cobbling together a solution that works and,

except by pure chance or coincidence, follows no best practices or most efficient

means. I cannot condone its use by any other organization and can barely

condone it’s use by my own.

Consider yourselves warned!

THE PROBLEM(S)

1

Update

Feature Services

GIS Data

Update Stand-Alone

Items

Zipped CAD Files

New Open Data Site

ArcGIS Online

2

Load Large Number

of Items

Zipped Aerial Photos

3

THE SOLUTION(S)

1 – Update Feature Services

• Use the ESRI ArcGIS Online (AGOL) Feature Service

Writer! Simple and Easy

• Publish to FME Server

LESSONS LEARNED:

- Create feature service in

AGOL first!

- Fast enough to just truncate

and load every time

2 – Update Stand-Alone Items

• Use the httpCaller

• Publish to FME Server

Your 3 Best Friends

LESSONS LEARNED:

- HTTP Method

- Query String Parameters:

need f & Token

- Headers: let me know

3 – Load Large Number of Items

• Use the httpCaller

• Keep track of returned unique URL’s for later use

• Loaded ~4200 zipped tiff images (180 Gb)

LESSONS LEARNED:

- Multipart / Form Data req’d

- Query String Parameters: f,

token, type (Image, etc.), title

req’d

- QSP: optionally add

description, tags, licenseinfo,

access

REST Easy…1. If I can do it…so can you!

2. OR…Be patient…FME will likely

come out with writers to make this

easier

3. This can be applied to other REST

API’s

SHARE IT

CREATE IT

SOMEONE WILL

MAKE IT BETTER
