At the 2014 Esri User Conference, the Big Data team gave several presentations, including two technical workshops entitled: ‘Big Data and Analytics: The Fundamentals’ and ‘Big Data and Analytics with ArcGIS’. We presented our open source GIS Tools for Hadoop (shared on GitHub), as well as some research that we’re currently pursuing (exciting things to come!). We gave demos using both our open source tools as well as the prototype tools being currently researched.
For the demos (source data consisted of > 170 million data points that represent all the taxi cab trips in New York City in 2013), we ran all of our analytics on a Hadoop cluster back in Redlands. A twenty node cluster may seem like a big investment (and it can be); but, it doesn’t have to be. Enter the DREDD cluster… Continue reading
Is ArcGIS 10.2 crashing when attempting to add shapefiles to ArcMap? We see your error reports coming in and we want you to know there’s a fix! For more details about this issue, please see this blog.
This reminder comes from Kirsten Pinkston in Esri Technical Support.
In all the excitement of the 2014 Esri UC, you may not have heard about GeoNet. Maybe you heard the name from Jack’s announcement during the plenary, maybe you got an email or saw it from your social media connections, maybe you’ve logged in but were not sure where to go. In any case, I wanted to help you understand more about GeoNet, how it applies to you and how you can get started.
Purpose of GeoNet
GeoNet is here to extend the user conference experience to 365 days a year. Take all of the networking, collaboration, knowledge sharing, and product support from the conference and combine them into a single community that spans the globe. From that, you have GeoNet. Continue reading
The Big Data development team at Esri is excited to announce a major performance speedup in ST_Geometry for Hive, which is part of Esri’s open-source Spatial Framework for Hadoop. The amount of performance gain depends on the type of spatial query run and on the size of the table in Hive. The biggest gain comes with relational operations such as ST_Contains and ST_Overlaps. In general, the performance gain will be greater with larger tables — exactly where it helps the most.
Just wanted to give everyone a heads up that we will soon be rolling out a new, evolved discussion forum over the next few weeks as part of the new Esri community platform called GeoNet.
For more information and to discuss further, feel free to jump into the conversation here.
The data health checks are returning to this year’s User Conference. Bring a sample of your data in a file or personal geodatabase and an Esri industry expert will review the overall quality of your data. The health check is a quick and easy way to get an insight into whether or not your data meets your business rules. This year Esri is offering the health checks to users in the following industries: water/wastewater/stormwater, electric & gas, roads & highways, land records and addressing, and 3D. You can sign up for this 45-min review of your data by sending an email to firstname.lastname@example.org. Please include your name, organization, phone, email, dataset you’re bringing and preferred date/time for the appointment.

Esri is pleased to announce the beta release of ArcGIS Pro, which is a new ArcGIS for Desktop application that provides many exciting features. ArcGIS Pro is designed for GIS professionals who need to visualize, edit, and perform analysis—in both … Continue reading
Duplicate features in your GIS can cause problems during analysis. A typical scenario is when only one of the duplicate features is updated but the analysis runs on the other not-updated feature. This will result in incorrect analysis. Another scenario … Continue reading
Have you heard about the OGC GeoPackage specification (http://www.opengeospatial.org/standards/geopackage)? It is a newly minted OGC spec that defines GeoPackages for exchange and GeoPackage SQLite Extensions for direct use of vector geospatial features and/or tile matrix sets. Esri has actively participated in the spec activity from the very beginning. To this end, we were one of the very early adopters of the specification ( early support even before the spec was approved by OGC membership). Continue reading
