Meltdown and Spectre patches from Microsoft impacting ArcGIS Server on Windows Server 2008 R2

Esri have announced today that the recently released Microsoft patches for the widely reported Meltdown and Spectre vulnerabilities are causing significant problems for all versions of ArcGIS Server running on Windows Server 2008 R2 or Windows 7. Later versions of Windows Server appear to be unaffected.

Esri have published the following technical article relating to this issue:

Esri is currently investigating the issue with Microsoft.

Esri will provide patches for all supported version of ArcGIS Server including: 10.3, 10.3.1, 10.4, 10.4.1, 10.5, 10.5.1, and 10.6, as well as 10.2.1 and 10.2.2.

No delivery date for the patches is available at this time, however Esri’s development team is working on this with the highest urgency.

In the interim please do not apply the Windows patches listed in the technical article to any Windows Server 2008 R2 server running ArcGIS Server.  If these Windows patches have been applied then these will have to be uninstalled.

Please follow Esri’s Security Standards & Architecture Team for the most up-to-date information.

A blog outlining Meltdown and Spectre Processor Vulnerabilities includes Esri’s recommendations for ArcGIS deployments and provides a number of references for vulnerability and vendor specific notices.

If you have any questions or concerns, please contact your local Esri distributors support team (for Esri Australia clients, use My Esri, or 1800 447 111)

GDA2020 & ArcGIS

It is now official on the 15th of December 2017 Geoscience Australia and the Intergovernmental Committee on Survey and Mapping (ICSM) launched the new GDA2020 datum.

In support of the new Australian datum, the following tools and resources have also been released by Geoscience Australia and ICSM:

·       the ICSM GDA2020 Technical Manual;

·       additional ICSM datum modernisation Fact Sheets;

·       GDA94 to GDA2020 Transformation Grids;

·       Geoscience Australia’s GDA94 to GDA2020 Online Transformation Service; and

·       AUSGeoid2020 to convert GDA2020 ellipsoid heights to the Australian Height Datum.

So what does this mean for the ArcGIS product suite? Well from ArcGIS Pro 2.1 and ArcGIS 10.6 onwards all state, territory and national projections that incorporate the GDA2020 datum are supported.

Exciting changes to Esri Australia’s Technical Support

Esri Australia is updating its Technical Support System and integrating tighter with Esri. This broadens our knowledge base, improves the visibility to you and generally make it easier for you to get your issues resolved. The main difference you’ll notice straight up is that emails will come from This is Esri’s ‘Global’ support email address and is what all of Esri and its distributors will use to communicate with their clients, but don’t submit your support requests through this address. You can continue to use to log new cases but we are considering phasing this out and directing you to use My Esri to manage your support cases.

You’ll notice a new “Support” tab in My Esri. This is where you’ll go to view your support activity and log a new case. In order to see this tab, you’ll need to be linked to an organisation and have the “View support information” assigned to you. We’ve automatically assign this permission to the administrators of your organisation to get you started. Continue reading

Big data, cloud storage & distributed computing


The Internet of Things (IoT) has completely changed how we architect modern enterprise geospatial systems. We now must consider stream services (maybe traffic or weather), cloud storage options (possibly buckets or blobs) and how we process large datasets over distributed infrastructure.

These are important considerations when analysing your data to make informed decisions and improve business processes.

Alternatives to ground control in drone mapping

In my previous article I highlighted the importance of ground control for aerial drone surveying. You really can’t provide a GIS ready product unless it is coordinated by ground control. Or can you? Now I am not going to start advocating not using ground control but what if you can’t acquire ground control for your given area of interest. Are there other options?? Well yes there are. They are not as accurate as supplying surveyed ground control but they will provide a product which can be used in your system if you just need to view a mosaiced image.

Considerations before you fly your drone for Mapping

In my position I talk to a lot of different clients about their requirements for drones. I hear of clients wanting high resolution aerial photography, elevation models, performing volumetric analysis, outputting point clouds for updating engineering designs, change monitoring and inspection scenarios. Every client has different thoughts and ideas on how they best make use of their investment. In all of these great ideas I often find that there is a great void between the understanding of what a client is looking for and their understanding of what is achievable.

Whether you purchase a helicopter, smaller quad copter or a fixed wing drone, all are delivered a flight control unit and flight management software. You’ll often though have to supply your own Smart Phone or tablet to run the software. However, it is not until you decide on exactly what you want to use the drone for, does the realisation of what is really required to achieved those results become apparent. If you are going to use it for talking single aerial pictures or video then the manual flight controller might be sufficient, however if you want to be able to use the drone for comprehensive orthomosaics or elevation modeling then there are key considerations that are required.
