Why Open Data? And Why Now?
Citizens are demanding access to open data like never before.
We want it.
Great advances have been made in technology. Citizens are tech
savvy and aware.
We have the ability.
Better decisions are being made by the mass population.
Benefits are undeniable.
Why does this matter?
Build innovations on top of institutes and empower citizens across the globe.
What is Open Data?
“Open data and content can be freely used, modified, and shared by anyone for any purpose”
opendefinition.org
“Open Data is free, public data that can be used to launch commercial and nonprofit ventures, do research, make data-driven decisions, and solve complex problems.”
Open Data 500
Open Data Audiences● Citizens who want to examine the data
and answer questions they have.● Researchers and journalists who want to
gather and analyze the data to tell stories.● Developers who want to use the data to
build applications

Ingredients for Open Data Portal Success
UpdatingDatasets should not be static and
should be regularly updated.
How to keep your data up-to-date:
Provide your data as a published feed (e.g. RSS) or API.
Connect your open data platform directly to the master database.
Enlist the help of FME to sync your master data store with your open data repository.
Coordinate SystemProjections
(Spatial Data Only)
Projection Support● Advanced users should be able to choose their
projection. ● Local (e.g. State Plane or British National Grid)
and global projections should be provided. ● Globally we would recommend:
● WGS 84 Lat/Lng (EPSG: 4326)
● Spherical Mercator (EPSG: 3857)
Ensure Data Quality
Pay Attention To Data Quality● Ensure you’ve covered off our Data Quality
Checklist○ FME can automate the checking
● Check out csvlint.io -- a free CSV quality checker
Delivery MechanismsFormats / APIs
Data should be available in...
Tabular:● CSV● JSON (API)
Spatial: ● GeoJSON (API)● Shapefile
Tabular:● Excel● XML
Spatial: ● AutoCAD DXF/DWG● Esri File Geodatabase● GML● KML● Mapinfo TAB
