Core-hours are the unit that is used in GeoAnalytics Engine to track the resources used in processing and analyzing your spatial data. In this post we’ll explore the concept of core-hours associated with the Connected licensing model, learn about the functions for tracking core-hours usage, and examine how many core-hours are used for a few example tasks.

If you work with GPS data collected along routes you probably know that it can be messy as a result of GPS drift. Tools like Snap Tracks are useful to clean up GPS data, by matching the GPS points to line segments. But, you need a network dataset with from- and to-nodes defined. In this post we explore how to add that information to network datasets.

PThe Overture Maps Foundation released the second version of their world-wide open map data on October 19. These datasets have an incredible amount of detail and great coverage across the world, and you can easily incorporate them into your spatial analyses using GeoAnalytics Engine. Let's take a look at how this works!

Point locations are an overwhelmingly common input to spatial big data analytics, but our raw data may not already have all of the attributes we need. In this post, we'll explore ways to enrich point-level data to support big data analytic workflows using ArcGIS GeoAnalytics Engine.

This blog provides an example of the new Polygon Centerline function, which can help to convert GPS points for movement data into single polylines representing the common path across all tracks in the data. The functions and methods demonstrated can be used for consolidating any movement data into central paths.

Spatial data is just like all of your other data – it’s messy. But decoding the problems can be a bit trickier since spatial data isn’t often a normal string or number that you can inspect in a data table. It’s important for professionals dealing with spatial data to be aware of the sources of errors in order to accurately interpret and use spatial data.

In this post, I will discuss methods for collecting Census attributes and geographies to use in Tableau. We’re going to get into a bunch of different technologies along the way, but don’t let this stress you out. In most cases, you won’t need all of this. My goal is simply to give you everything you might possibly need in order to collect and map this data.

Fourth in my QGIS series on the Flerlage Twins blog – this post focuses on the problem of ‘what is nearby?’ While there are some features built into Tableau to help with this (e.g., field calculations for buffers and distance, as well as the spatial intersection join type)—there are some types of proximity analysis that they can’t do. But, some nice data prep in advance can help you calculate many of the attributes you might need to unlock some special spatial functionality in your Tableau workbook.

With support for map layers in Tableau starting in version 2020.4, there is a lot that we can do to enhance the design in our maps! Recently I’ve been answering a lot of questions about how to do more with changing the color, size, and transparency of polygon outlines and how to move point symbol & label locations for polygons. So, I’m just writing up all of the little tricks so you can see how incredibly easy this can be!
