Workflow

ArcGIS Online Analysis Workflow

Prepare data

Add to map

Perform analysis

Review results

Rerun analysis

Assemble data

• Evaluate analysis needs• Search local and online resources• Create, publish, and filter data

Feature service Map service with feature layers ArcGIS Online Map Notes ArcGIS Online Route layers Comma-separated values (CSV) file (.csv) GPS exchange format file (.gpx) Shapefile (.zip) GeoRSS web feed WFS layers

Supported data types

Prepare data

Update map

• Bring data into ArcGIS Online map viewer• Optionally

- Set symbology, map display extent, and bookmarks- Save map

You can also browse to layers from the analysis tools without adding the layer to your map

Add to map

Analyze data

• Open Analysis tools

• Determine appropriate tool(s)

Perform analysis

Analyze data

• Determine appropriate tool(s)• Apply parameters

Perform analysis

Use and review results

• Added to web map• Published as hosted feature services within the organization• Configure results layer – pop-ups, symbology• Share the results

Machine Learning Integration

Find Point ClustersClustering: The grouping of observations based on similarities of values or locations

Find Point Clusters:Use machine learning techniques to find clusters based on spatial location and a specified cluster sizeSeparate input data into clusters and noise

Summarize Center and Dispersion Measuring the distribution of a set of features to summarize the spatial characteristics such as central features and directional distributions.

- Where's the center?- Are there any directional trends?- How dispersed are the features?

Demonstration review
