GIS: More Than a System of Record

Is your GIS living up to its potential? With today’s technology, your GIS can be so much more than a system of record. I know GIS is great at storing your authoritative data but it’s also good at sharing your data and creating actionable information from your data. Today, GIS is a system of record, a system of engagement and a system of insight….and it’s easier than ever to implement!

There are many definitions for system of engagement. Some define it as a system used directly by employees. Others say it as a system that encourages and enables peer interaction. At Esri, a system of engagement is defined as a system that manages and promotes user collaboration and interaction. It overlays and complements an organization’s investment in a system of record by providing easy access to data as well as easy to use applications that enable collaboration across your organization.

How do you implement a system of engagement? You have to start with Web GIS. Now is the time. Web GIS modernizes your workflows by using web services to deliver data and capabilities. It enables a whole suite of applications that support the work that you do.

For example, optimize your field operations with apps that improve collaboration and streamlines project coordination by providing the same authoritative data to field and office staff in real-time. Access to the same information at the same time can reduce errors, boost productivity, and save money.

What is your data telling you? This is where a system of insight becomes important. A system of insight facilitates organizing, transforming, and analyzing your data. With analytics you can discover secrets in your data, evaluate trends, and even integrate non-spatial data…resulting in actionable information. Analysis can be performed on the desktop, online, or within Insights for ArcGIS. Whatever your need is, there is an analytical tool that can help.

Are you getting the most out of your GIS?

If not, Esri’s water team is always willing to help.

ArcGIS Online Service Disruption

Thank you for your patience on Tuesday 3/20/18 as we worked through the ArcGIS Online disruptions in providing access to your services, maps and apps.  We understand the importance of continuing to provide a resilient, redundant and well architected system and we are confident that everything is back to normal and no data was lost.

What happened :

Between 9:00AM and 12:15 PM EST Tuesday March 20, 2018  ArcGIS Online experienced periods of disruption.

Why did it happen :

The ArcGIS Online system that runs on web servers hosted within Amazon Web Services (AWS) experienced timeouts and failures in accessing AWS Services including  S3. These failures were the result of  S3 network connectivity errors reported and described by AWS on its status page.  These connectivity issues in AWS affected ArcGIS Online availability even though the ArcGIS Online system runs on redundant web servers and across multiple data centers.

Our Response:

The ArcGIS Online operations team worked with Amazon during the event to diagnose the problem and then began to work on the reconfigurations needed for the web servers to access the AWS services via alternate network routes. In the meantime, the original network connectivity problem was resolved by AWS.

Based on this incident we are working on an automated approach to  detect network connectivity failures and to reroute network connections to the relevant AWS services where applicable.

Additional things we will be working on:

- ArcGIS Online is already taking advantage of redundancy and fail over across data centers. We will investigate and consider additional improvements including network endpoint failover where applicable as well as other mitigation strategies.

- We will continue working with AWS on further details of the root cause of the incident, and will examine engineering and operational improvements.

ArcGIS GeoAnalytics Server: DevSummit 2018 FAQs!

This year’s Esri Developer Summit was the biggest one yet. Crucial conference highlights include: the giant outdoor carnival full of games and food and fun, and the opportunity to talk with visitors to the GeoAnalytics showcase. Getting to hear your questions, comments and use cases is always exciting and inspiring. In case you weren’t there, our team has compiled the most frequently asked questions here in hopes of answering yours!

“What is ArcGIS GeoAnalytics Server?”

GeoAnalytics Server is a licensing role for one or more ArcGIS Server machines used for the analysis of large volumes of vector and tabular data. What’s unique about these analysis servers is that they can distribute processing across multiple machines and cores. This means that when your datasets become too large to be processed on a single machine or core, GeoAnalytics can step in to speed up that process. Jobs that may have taken months, weeks, or days can take hours or minutes with GeoAnalytics.

“I see that the ArcGIS Enterprise portal’s Map Viewer has both Standard Tools and GeoAnalytics Tools. What are the differences, and when would I use one or the other?”

Standard tools are available by default in ArcGIS Enterprise and perform feature analysis using your hosting server. These tools are useful when you are processing average-sized data. GeoAnalytics Tools, however, process data in parallel on your GeoAnalytics Server, and are specialized to process larger amounts of data more quickly. Both toolsets contain some similar tools, like Aggregate Points, Join Features, and Find Hot Spots, but GeoAnalytics’ extra edge is that it provides tools to track trends, patterns and anomalies in both space and time.

“GeoAnalytics, GeoEvent, Insights, and analysis in ArcGIS Pro: How does it all work together?”

GeoAnalytics, GeoEvent Server, and Insights for ArcGIS complement each other, but also work well in isolation. GeoEvent is used to ingest real-time stream data from sources like sensors and GPS measurements. GeoEvent exposes ingested data as feature layers, which can optionally be explored further in Insights or processed using GeoAnalytics Tools. Insights provides a data workbench experience for your data, allowing you to explore, iterate on and share your findings via charts, graphs and maps. Insights can take advantage of different analysis engines, so while you are using your Insights workbook, your analysis may be powered by Insights, standard analysis tools, or even GeoAnalytics Tools, depending on the configuration of ArcGIS Enterprise.

“I have a huge dataset, and it’s not drawing quickly. I want to draw a zillion points, how do I do that?”

Well, you may not want to. Why? Because visualizing millions and trillions of features on their own isn’t informative. Instead, consider using GeoAnalytics to visualize big data patterns by aggregating and summarizing trends. This allows you to explore and find patterns that would otherwise go unseen amid your many features. For example, below are millions of….can you tell? Exactly — it’s hard to see anything with that many points. These are taxi pickup locations in New York City (Do not try this at home!)

“Am I able to automate GeoAnalytics workflows? Does it work with the Jupyter Notebooks I’ve been hearing so much about?”

Yes, and yes! The ArcGIS Python API can be used to automate and execute workflows. For those of you who are fans of Jupyter Notebooks, GeoAnalytics Tools can be executed there, too! Additionally, GeoAnalytics Tools can be used with Model Builder in ArcGIS Pro and in ArcPy. If REST is your preferred tool execution method (props to you!) then you can run the tools through the REST API.

“That all sounds great. Now, how do I install it? Is GeoAnalytics an extension or a separate install?”

GeoAnalytics is a server role within ArcGIS Enterprise, not an extension. It builds off of the ArcGIS Enterprise base deployment. First, install ArcGIS Server and license it for GeoAnalytics, then federate your GeoAnalytics site with your Enterprise portal. You’ll need to also install and configure the ArcGIS Data Store (spatiotemporal big data), used as an output for your results. Once your environment is all set up, you can start crunching some data!

Hopefully this was useful in answering your questions. Which features are you excited about? Are you currently using GeoAnalytics? Let us know in the comments below!
