Turning Data Into Information with Geo- Ontologies Justin Lewis - TerraFrame

A bit about us

Some Basic Requirements Remote data collection (no internet) Data syncing across systems Data manipulation & analysis Dynamic data mapping & charting Report generation Complex domain models Mapping data with NO geometries Expansive configuration...

Not Easy

Some Common Challenges 1.Disparate data sources 1.Limited organizational resources (no GIS staff) 1.A lack of quality GIS data 1.Need for robust data + vis manipulation tools

DATA

Turn messy & incomplete data into useful data

How do we meet these needs?

FOSS + 4G Community And many others

A Different Approach A method for modeling data as ontologies that can help turn messy and/or incomplete data into useful data.

Ontology Crash Course

Ontologies | User Data

What are ontologies? A style of programming that allows you to define human-like inferences about data objects.

To Elaborate Ontology is a has a Geo-Ontology is a located in

An Ontology Model for Geo Universal A collection of geographic locations representing a common political hierarchy. Ex: Countries GeoEntity A single geographic entity within a Universal collection. Ex: South Korea

GeoEntity

Universal

Purpose of Universals / GeoEntities Provide a central geographic context for the system

Strengths Of This Approach 1.Well defined spatial and non-spatial relationships 1.No dependency on geometries (less GIS)

Ontologies in the OPEN RunwaySDK An ontology based data engine. GeoDashboard A visualization layer that sits on top of RunwaySDK.

What about user data?

User Data Is Different User data can maintain relationships to GeoEntities and Universals giving user data spatial context.

JSON { "sales":[ {"product":"widget 1", "amount":"2", "loc":"denver"}, {"product":"widget 2", "amount":"5", "loc":"seattle"} ] }

GeoJSON { "type": “feature”, “geometry”:{ “type”:”point”, “coordinates”:[124.6, 10.1] }, “properties”:{ "location":"denver" }

Common GIS Formats

Spreadsheet

The Reality of User ALL Data Incomplete Messy Non-Existent (geometry)

Why is this valuable? Generic data integration, manipulation and visualization

What do I mean by “generic”?

My data, Your data, Everyone’s data

No Problem No Geom?

How does this work in a web application?

What about geometries?

Geometries Are Used To Visualize GeoEntities Visualize lowest level data points Algorithmically enhance data Validate spatial relationships However, geometries are optional
