GDA94, GDA2020 and WGS84; The projection dilemma

Progress supporting GDA2020:

The Intergovernmental Committee on Surveying and Mapping (ICSM) & Geoscience Australia (GA) recently released the definitions for the GDA2020 datum and associated projected coordinate systems covering Australia and its territories. Esri Australia has been working closely with ICSM & GA to ensure that ArcGIS software products support the new definitions.  Version 10.6 of ArcGIS and version 2.1 of ArcGIS Pro both include support for the new datum and projected coordinate systems (you can learn more in the Esri Australia Technical Blog)

Avoiding alignment issues mixing datums:

Web GIS, by default, displays data in the projection WGS84 Web Mercator (auxiliary sphere). When mapping data is shared to ‘Web GIS’, data is automatically reprojected ‘on-the-fly’ to this web projection in order to align with the displayed basemap and fit with the global projection. Most users do not realise that their data is being reprojected and in many instances occurs without issue.

However, while organisations are migrating to GDA2020 from GDA94 and using mixed data containing both datums, these mixed data sources will create a challenge when displayed in WGS84. The issue occurs when data is reprojected to the WGS84 Web Mercator projection.   Continue reading

Geoscape & ArcGIS

Geoscape is an analytics-ready, 3D built environment dataset providing location-based insights for every address in Australia. It captures building footprints and heights, roof construction, surface cover, tree heights, the presence of solar panels and swimming pools and more. The data can be visualised using mapping platforms and 3D modelling tools.

I have put together a short video showing just some of the ways it can be used within ArcGIS.

I am also getting some experience in for becoming a TV weatherman, hopefully not too distracting.

How To: Set Up an ArcGIS Developer Subscription (ADS)

ArcGIS Developer Subscriptions (ADS) are a cost-effective way to license multiple ArcGIS products and tools for developing solutions. Many users acquire an ADS to develop custom GIS applications for existing technologies and workflows. Note: An ADS is formerly known as an EDN (Esri Developer Network) License!

 

There are five different types of subscriptions on offer including:

  • A free “Essentials” unlimited subscription;
  • Or a yearly purchased subscription that includes additional ArcGIS software for development and testing of applications:
    • Builder (includes Desktop Basic)
    • Professional (Desktop Basic + Extensions + Enterprise Advanced)
    • Premium (Desktop Standard + Extensions + Enterprise Advanced)
    • Enterprise (Desktop Advanced + Extensions + Enterprise Advanced + Additional ArcGIS Server Capabilities)

 

With a yearly ADS you will receive:

  • A Developer Subscription (account for developers.arcgis.com);
  • An ArcGIS Online Development and Test Organisation (new Organisation for ArcGIS.com with 5 named users for testing your developed applications);
  • And Licenses (ArcGIS Desktop, and/or ArcGIS Enterprise and ArcGIS Engine) associated with your ADS subscription level in My Esri.

 

The following post will run through how to set up each of these components once you have purchased a yearly subscription:

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: https://support.esri.com/en/Technical-Article/000017464

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, support@esriaustralia.com.au or 1800 447 111)
