The R-ArcGIS Bridge is a little-known secret to improving your methods of geostatistical analysis. By integrating ArcGIS and R you can have the best of both geospatial and statistical platforms. With the R-ArcGIS Bridge you and I can now perform and visualise comprehensive statistical analysis directly in ArcGIS Desktop.
Why would you use R?
R is a powerful platform for solving big data science problems. R is both an open source language and programming environment, widely used for statistical analysis. R offers an online repository with 6,400 statistical problem-solving packages.
The R-ArcGIS Bridge is a way to load your spatial data into R, or, create custom Geoprocessing Tools in ArcGIS that leverage the capabilities of R. The Bridge can be directly connected to either ArcGIS Pro (version 1.1+) or ArcMap (10.3.1+), and R (3.1+) or RStudio. The R-ArcGIS Bridge can then be used with pre-existing tools written in R, without the need to learn any code!
There are several uses of R-ArcGIS Bridge:
Use R functions to read and write spatial data
Convert between data types
Solve complex geostatistical problems
Write, configure, and modify an R script to be executed from a Geoprocessing tool
In my role at Esri Australia resolving Enterprise and Developer support issues, there’s rarely a day that goes by where it’s not immensely useful to investigate communication between the different parts of a system. When a component of a GIS is not behaving as expected, forming a complete picture of the behaviour across the system is often instrumental in understanding the underlying cause. This article will focus on the special case of intercepting HTTP requests generated by applications running on top of Microsoft IIS, such as ArcGIS Web Adaptor and the Esri Resource Proxy.
Recently in the Australian media there has been a lot of commentary around the impending update to Australia’s primary datum. From GDA94 to GDA2020. It has even made the British media http://www.bbc.com/news/technology-36912700.
At Esri Australia this has prompted a lot of questions from clients in regards to the support of the new datum GDA2020 in ArcGIS. Will ArcGIS support GDA2020 and when will ArcGIS support GDA2020?
Before we start to answer these questions I think it is important we understand exactly what the new datum is and why Geoscience Australia is moving towards a new datum.
Since May of this year, when I demonstrated a very early version of the new Insights for ArcGIS product at the Directions LIVE events Esri Australia staged around the country, it has been the topic of many conversations I have had – both internally and with customers.
Everyone is keen to understand where Insights fits in to the ArcGIS platform, and where it sits in relation to other similar products in the broader market.
There’s a buzz about this that I haven’t witnessed for some time in Esri circles, and I’ve got to say – it’s infectious. For me personally, Insights, and the GeoAnalytics Server that is also in the pipeline for ArcGIS 10.5, stand to be highlights of my work over the next year or so.
I’d like to share my early thoughts on Insights, and I hope that leaves you curious enough to find out more. Continue reading →
Directions LIVE 2016 kicked off in Melbourne on Tuesday 17 May and has just finished up in Canberra. It was a great tour, and it was terrific hearing how so many of you are making use of the technology for your various projects.
I had free rein to talk about five things that I think are powerful features of a portal (a portal being either ArcGIS Online or Portal for ArcGIS). I have recorded these sessions into the five separate videos below.
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.

So you’ve loaded your image into ArcMap and the image displays incorrect colour or there is no data values around the outside of the image that is masking crucial features in your map. How can you quick rectify these annoyances? Well this is where the Image Analysis window comes in handy.
Introduced in ArcMap 10.1 the Image Analysis Window is accessed from the Display menu in ArcMap . The Image Analysis window supports the analysis and exploitation of image and raster data in ArcMap, with a collection of commonly used display capabilities, processes, and measurement tools. Essentially all your image needs in one place.
