ArcGIS Velocity

What's new in ArcGIS Velocity (December 2020)

ArcGIS Velocity allows organizations to ingest, visualize, analyze, and act on data from sensors. It also enables processing of high-volume historical data to gain insights into patterns, trends, and anomalies.  Remote monitoring of assets, predictive maintenance, and process optimization are a few of the benefits you can gain from your IoT data.

ArcGIS Velocity is updated regularly, below is a quick overview of some highlights in the December 2020 release: 

Now, let’s take a deeper dive into each of these exciting new enhancements!

General

In this release spatiotemporal feature layers have been enhanced to support more of the same capabilities as hosted feature layers, in this case ownership-based data access and control. Editor tracking was added in the August release, and now you can configure permissions for editors such as whether they can view and edit all features (or only their own) as well as editing actions (Add, Update, Delete). See Data access and editing for more details. These capabilities will be followed by support for feature layer views in the next release, so that you can create different views of your data and share to stakeholders as needed.

Additionally, visualization options for the map image layer continue to be expanded. There are additional rendering options for when the dynamic aggregation switches over to raw features. Class break rendering for raw features now supports natural breaks, equal interval, standard deviation, and quantile. For more information, see Visualize map image layers.

Feeds, data sources, and outputs

feed is a real-time stream of data coming into ArcGIS while a data source loads stored data for use in a real-time or big data analytic. Integrating with popular data and messaging platforms is one of the key capabilities of Velocity.

With this release, the Kafka feed type has been enhanced with authentication support (SASL PLAIN). Kafka is an open-source distributed streaming platform that enables publishing and subscribing to a stream of messages, and can handle very high velocity data streams.

There’s also been a variety of logging improvements for feeds and data sources. For example, when polling a website or a RSS feed, logs are now captured with information about each request, how long the request took, and how many event messages were received.

An output is a result or action to be taken as the final step in a real-time or big data analytic. Analytics can emit data to a variety of different destinations, including storing data to a feature layer, sending an email, writing to a cloud store, and pushing to a third-party system for device actuation. For the December release, Feature JSON and GeoJSON can now be set as the format for the following output types: Azure IoT Hub, Azure Blob Store, Amazon S3, Kafka, and RabbitMQ.

Analytics

With real-time and big data analytics, you can gain insights from IoT data – detect incidents and anomalies, find relationships between different data streams, and uncover patterns over time. In this release, we’re excited to announce that real-time analytics have been enhanced to support stateful processing. Stateful real-time analysis allows detection of changes from prior observations of an individual track, while data is actively streaming. One of the most common applications of stateful real-time analysis is detecting an enter or exit to a geofence:

There are four new stateful tools/capabilities for real-time analytics:
