Everything happens at a place and occurs at some point in time. Space time analysis seeks to understand when and where (and sometimes why) things occur. With the evolution of ArcGIS Pro we now have the opportunity to not only successfully analyse patterns of time and space, but also immerse in a deep 3D visual experience.
ArcGIS allows you to exploit the space and time aspects of your data, allowing you to answer questions like:
- Is there an emerging hot spot?
- Are there any anomalies?
- Where your decisions or resource allocations effective?
Several tools, including Create Space Time Cubes, Cluster and Outlier Analysis, Emerging Hot Sport Analysis and Grouping Analysis assist with answering these difficult questions. So, let’s explore how we can utilise some these tools to analyse earthquakes that have occurred across South Australia. The quake data was sourced online from Geoscience Australia as a csv, recording the last 58 years of earthquakes across the State. Which I then subsequently created a feature class.

In the last couple of years Story Maps have become quite popular with ArcGIS Desktop / Online users. They provide a quick and efficient way to deliver important information or a message in a form of an easily-configurable web application that uses geographic data and can be enriched by adding various types of media content. There are thousands of story maps that you can access through ArcGIS online and it’s very easy to create your own.
One of my areas of expertise is 3D GIS and from time to time people ask me whether it’s possible to display 3D information in a Story Map. Well, the answer is yes. This functionality has been available for more than a year and I believe it’s time to write a blog about the workflow that will make your story maps 3D –enabled.
In this blog I will demonstrate how to use CityEngine 3D scenes to publish your 3D data to ArcGIS Online and create an interactive Story Map that uses 3D web scenes.
For the purpose of this demo, I used one of the CityEngine Examples provided by Esri Inc. on their CityEngine Gallery web page, available here:>>
With the growth of the so-called Internet of Things (IOT), and a data landscape that is getting broader every year with more and more organisations taking up new and varied types of spatial data like LiDAR, real-time streaming feeds, and unstructured Big Data, I hear the question “What do I do with all of this?” come up a lot.

I only discovered relatively recently that the Desktop suite is not limited to mapping Earth. Hidden amongst the thousands of coordinate systems available, you can find those for mapping planets within the Solar System.
Just for kicks, I downloaded all the geological data from Mars to have a look in ArcGIS Pro and see how it would fare in the hybrid 2D/3D interface.
You can try this out for yourselves by downloading the data from the USGS here. The datasets are conveniently provided in a file geodatabase and the layers come with some standard symbology in MXDs, so it’s an easy feat to import into ArcGIS Pro.
In response to the growing demand in providing education and training to interested users around Esri’s cutting edge 3D software tool CityEngine, Esri Australia’s training team has recently developed a new training course- CityEngine 2014.
This training course has been designed to provide students who are about to begin constructing realistic models of 3D cities with some foundational knowledge of how CityEngine works, and how to use it to create models, import GIS data and publish their results on ArcGIS Online.
The CityEngine 2014 training course will also be of interest to those who are already CityEngine users, and have made their first steps in navigating this advanced 3D modelling software, guided by Esri Inc’s tutorials and exercises.
