Space and Time Cluster Analysis – Can ArcGIS help predict the future?

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:

  1. Is there an emerging hot spot?
  2. Are there any anomalies?
  3. 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.

It’s time to connect with Network Analyst

Do you want to improve routing efficiency within your business, with requirements to minimise costs, accessibility high to maximise profit and maintain a high quality of service?

If the answer is ‘yes’, Esri Australia has an exciting 2-day course in which you will acquire the skills needed to use the ArcGIS Network Analyst extension to assist with the above.

I recently had the privilege of teaching this course for a NSW client. They had a need to learn about the ArcGIS Network Analyst extension to help improve the routing of their extensive fleet of vehicles, in particular their trucks. For example, ensuring routing decisions considered height, weight and length restrictions when routing from source to consumer. Subsequently, pushing routes and directions directly to field and mobile crew to ensure correct route decisions. With the added value of decreasing fuel costs and efficient time management.

How to create capabilities files for your OGC Service with ArcGIS Server

Have you ever wanted to include capabilities files with your OGC Service? An OGC service exposes service-level metadata through its capabilities file. The capabilities file is the XML response that clients receive when they make a GetCapabilities request on the service. Below is my step by step guide on how to complete this process for a WMS Service. To use external capabilities files with OGC services in ArcGIS, you will need to create the files for use with the  service. In my situation I want my WMS service to support different versions of WMS protocols – for example 1.0.0, 1.1.0, 1.1.1 and 1.3.0. To do this I must create one capabilities file for each version of WMS.

It’s time to get on board and set up your profile on GeoNet!

Hi everyone,

Most of you all have already probably noticed that Esri has transformed their old support forums into a new and exciting community endeavour – GeoNet.

So what is GeoNet?

GeoNet is the place where you can share, chat, and collaborate on all things Geo. It’s your chance to connect with other geospatial enthusiasts around the globe. GeoNet is more than just a new forums location. Forums now are only a part of a larger community. This community is there as a tool to help you, the GIS user. You can upload files, collaborate on documents, upload files, write blog posts, share videos and much more.

So what are the cool new features of GeoNet?

Well the first thing you will notice when logging in with your ArcGIS account is a recent activity feed. Here you can see all the most recent updates from everyone in GeoNet – similar to a twitter or Facebook feed. The next big tick from me is your own profile page. Here you can upload a profile pic, create an avatar; add a bio about yourself and note your skills and expertise.
