Data Visualization

Purpose of group:

Keep up to date on data visualization technologies;

Assess tools and keep a list of required functionalities;

Be informed and prepared should a funding opportunity arise.

Mandate

Two data portals (limited visualization)

Spatial portal displays data as single symbol (i.e. mapping of location, soil classifications)

Numeric data portal (some categorical charting)

Visual and data literacy

Find patterns in data

Convey messages

Interact with data

Support teaching and learning through visuals

Why visualize?

Visualize attributes of spatial data

mapping of locations and spatial attributes (boundaries, rivers, terrain, soil classifications)

Visualize numeric data geographically

spatial distributions of geographic characteristics (species, disease, demographics)

Visualize statistics

wide variety of graphic methods used to portray patterns, trends, and indicators.

Desired Functionality

Visuals

What is possible?

Include an image allowing user to create a map from spatial data on the fly

Visualizing spatial data and attributes

Geological classifications

Spatial analysis using buffer zones

Visualizing attribute data -

spatially

Population density

Language distribution and perceived health

Visualizing

attribute data –

spatially, on the fly

1.

2.

3.

Create indicators, indexes; to visualize statistics

Custom maps, symbology, and filtering

Visualizing numeric data and statistics

Charts, graphs, diagrams, tables

Visualizing numeric data -

in charts, graphs, on the fly

Community profiles

Visualizing microdata and

other data

GAP area?

Simple frequencies…..

Tool Type of data

Geocommons/GeoIQ Spatial and numeric data

Beyond 2020 Server (and other OLAP cube servers)

Beyond 2020 format (.ivt), aggregate data

Weave (Web-based Analysis and Visualization Environment)

Any kind of numeric data: spatial, categorical, continuous

Geo-clip (and other flash driven geographic visualization tools)

Spatial and numeric data

Many other tools! See Google doc: https://docs.google.com/spreadsheet/ccc?key=0AmVqurcWSW0KdDZwOHNPOXhnb0I1Nk1oOWN2Z3l0SlE#gid=1

Tools Watchlist

Visualizations present an opportunity for showcasing data in new ways Web-based tools to manipulate, map,

graph, and chart data

Convey information dynamically

Varying types of data can be visualized Spatial data and mapping

Numeric and attribute data

Microdata?

Many visualization tools exist Can be web-based

Some rely on open source /or proprietary technologies

Support different kinds of data

Summary

Any questions / comments?
