Nearmap WMS 2.0 – Important Update

Nearmap WMS 2.0

As of August 2022 Nearmap have updated their WMS server, they have referred to this update as "WMS 2.0" but this is not a change to the WMS version supported by Nearmap, it is still 1.1.1, and is just used to indicate a new implementation of their server.

This change will break existing Weave toc model configurations for the Nearmap WMS map engines, since the change involved the renaming of all of the layers in Nearmap. The Nearmap WMS map engine in Weave still works as it did before, but you will need to update any toc models you have that relate to the Nearmap map engine to reflect the new layer names.

Note that you should ensure the id attribute for each toc model entry remains the same after the update so as to not break any bookmarks.

Please review the Cohga Wiki Page for the most recent information and updates on Nearmap.

GDA2020 Upgrade Services

GDA2020 Background

From 1 January 2020 Australia has adopted the GDA2020 datum to represent coordinates on a more accurate and modern global reference frame. As a consequence, spatial information custodians are being encouraged to use GDA2020 as the foundation for their spatial data sets.

For data custodians this will mean converting their spatial data from their current datum (e.g. GDA94) to the new datum, and adopting the associated map projection change.

More information is available from the Intergovernmental Committee on Surveying and Mapping (ICSM) websites on GDA2020 and upgrades to the Australian Geospatial Reference System. Resources include the GDA2020 Technical Manual, FAQs, Fact Sheets and a GDA2020 Forum.

Cohga GDA2020 Services

If you are considering moving to GDA2020 then please contact Cohga to discuss what you will need to do from a Weave perspective. Cohga has a range of upgrade services to suit needs and budget and will work with you to identify what is the best approach for your organisation.

From a project perspective we recommend the following steps:


It is important to plan this upgrade project well, as the changes being made are significant and need to be carried out in a methodical and structured way. From experience we can advise that the more time spent planning this upgrade the better the outcome, so we encourage you to engage a Project Manager and adopt some Project Planning tools and processes.


It is vitally important that your clients – internal and external – are made aware of the changes you are planning as this will assist with the smooth transition to the new system. We encourage a communications strategy that provides clients with timely and informative updates to ensure there are no surprises at any stage of the project.

This communications strategy is also a good opportunity for you to promote yourself and your services by showing your clients that you are working to improve and modernise the system for them.


Your project plan should include conducting a full system upgrade in a test environment before upgrading your production system. This will provide you the opportunity to develop and test all the steps in the process to ensure your system is upgraded correctly and in the most efficient way.

Once you have your plan, scripts and processes defined you will be ready to upgrade your production system.


If you have planned well and tested your plan then the execution phase should be relatively straight forward and successful. Set aside enough time to roll out the upgraded production system and importantly communicate this change with your clients early.

Take the pain out of the GDA2020 upgrade. Cohga professional services team are ready to work with you and your IT team to deliver a smooth transition. Contact us now to start the discussion.

NTG Point Splash Screen

Petroleum Onshore Information NT Portal now Available

POINT Portal

On 17 February 2021 Minister for Mining and Industry Nicole Manison and Minister for Environment Eva Lawler announced the availability of the POINT system that provides public access to key information and data about onshore petroleum activities.

This new portal provides information relating to proposed and approved activities, including environmental approvals, environment management plans, monitoring data and compliance reporting.

POINT contributes to the government’s commitment of ensuring transparency in the development and regulation of the onshore petroleum industry. This free mapping portal provides information on the onshore petroleum industry in the Territory, including:

  • The Territory’s regulatory framework
  • Industry codes of practice and guidelines
  • Geological regions in the NT, including Basins and Sub-basins
  • Petroleum titles
  • Petroleum wells
  • Companies with a petroleum interest in the NT
  • Petroleum activities.

The POINT system is the first enterprise level Weave 3 solution to hit the market. Previous Weave 3 implementations have been simple public clients and this POINT solution illustrates the maturity of the Weave 3 platform.

POINT has a clean, intuitive and modern interface on both the desktop and mobile clients. A feature developed for this project is the Data Catalogue which provides a tree like navigation to documents served to it from an external third-party document management system. Within this catalogue is the concept of Relationships, where the administrator can define relationships between entities and let the end user navigate (up and down) through the relationship tree using the Data Catalogue.

Relationships is a core part of Weave 3 and available to all users. Cohga is happy to chat to you about this new capability and how it can be used in your context.

Take the pain out of Weave 3 set up and configuration. Cohga professional services team are ready to work with you and your IT team to deliver a smooth transition. Contact us now to start the discussion.


Weave Supports SAML

Authenticating with SAML

Security Assertion Markup Language (SAML) is an open standard where you can use one set of credentials to log in to many different websites.

As of Weave 2.6.5, SAML 2.0 is supported by Weave as a means of authenticating users.

SAML is the specification that outlines the steps required to perform the authentication but there are multiple different implementations of SAML Identity Providers (IdP), Weave itself is a SAML Service Provider (SP), this includes:

Active Directory Federation Services (ADFS) - a Single Sign-On (SSO) solution created by Microsoft

  • Azure Active Directory (Azure AD) - a cloud based SSO solution provided by Microsoft
  • Keycloak - an open source identity and access management solution provided by Red Hat
  • Cognito - an AWS identity provider solution provided by Amazon
  • Okta - a cloud based SAML identity provider created by Okta, Inc.

Weave itself uses the Keycloak Java library, which is different from the Keycloak identity provider listed above but is provided by the same team, for communicating with whichever SAML Identity Provider you wish to integrate with. This page documents how to configure Weave so that it will use this Keycloak library to communicate with your chosen SAML IdP.

Learn more about SAML Authentication

Take the pain out of SAML configuration. Cohga professional services team are ready to work with your IT team to deliver a smooth transition. Contact us now to start the discussion.

Weave 2.6 Released

Weave 2.6.0 has been released on 8 November 2019. This is
important news for customers who are using version 2.5.x as it means we will
now only be providing hotfixes for 2.5 releases, and any new or enhanced functionality
will be provided as part of 2.6.x releases

Note that the Weave 2.6.0 upgrade was aimed at modernising
the Java and Jetty foundation components in line with our continuous
improvement program and road map. By updating the Weave foundation frameworks we
are able to continuously innovate to provide the expected business capability
in an ever changing world.

Frequently Asked Questions

Do I have to upgrade to Weave 2.6.0?

Not immediately, but we recommend you start planning for this upgrade soon. Information on how to upgrade can be found on our wiki

What is the benefit of upgrading to Weave 2.6.0?

You will take advantage of more modern Java and Jetty frameworks, which will result in improved performance and capability. Also, you will be able to take advantage of any new functionality developed in Weave.

What new capability/functionality is available in Weave 2.6.0?

The Weave 2.6.0 release has exactly the same functionality as 2.5.30. New release capability can be found on our “What’s New” wiki page

How do I upgrade to Weave 2.6.0?

You must install Weave 2.6 to a new location, but you can copy your existing 2.5 configuration over to the new installation and you do not need to uninstall your previous Weave 2.5 instance. Information on how to upgrade can be found on our wiki

Can I upgrade to Weave 2.6.0 myself?

Yes, however some knowledge of your Weave infrastructure and networks is required. To perform the initial installation, you will require the Weave installer .jar file. This can be downloaded from Latest Downloads page if you have a current support subscription.

What if I have custom bundles?

Custom bundles can be migrated to 2.6 easily and quickly, however, that will only be the case while the 2.6 code is still basically the same as 2.5. As more developments are made in 2.6 the less likely it will be that a 2.5 bundle will work with 2.6, which may mean there could be more effort required to get older bundles working.

Can Cohga assist me to upgrade to Weave 2.6.0?

Absolutely. Cohga has a professional services team who can work with you to devise, plan and execute your upgrade strategy. Upgrade effort will be determined by your requirements and your IT/IS rules of engagement as well as on the number of systems you have and the complexity of those system. A typical upgrade conducted by Cohga should take no more than 3 – 5 days. In addition, Cohga provides a 30-day warranty on all our upgrade services so you can have peace of mind that issues will be resolved quickly and effectively if they arise.

Weave Mobile Saves Water for the Northern Territory

After a poor wet season across the Territory, water resources have not been refilled and the Department of Environment and Resources is working to get the message out to the community that everyone needs to do their bit to reduce demand on the groundwater resources.

In recent years, 10% to 15% of Darwin’s urban drinking water supply has been sourced from groundwater aquifers in the Darwin rural area resulting in some groundwater systems operating at critical levels. At this rate some bores in the rural area will become unserviceable this dry season which means, amongst other things, rural residents may need to purchase and store drinking water if this happens.

As part of its natural resource management plan the Department of Environment and Resources has created an initiative called “Help stop the Drop!” which includes marketing activities and community consultation, as well as tools for helping residents understand bore water usage. One of these tools is the Know your bore web application based on the Weave Mobile Client.

Figure 1 –

This is a simple Weave Mobile Client that allows the public to search for and review the status of water bores in the Territory. Bores can be located using the standard pan/zoom touch capability of the map interface, or a simple search can be conducted using a property address or bore number. Once a bore is identified the relevant information about that water resource is displayed.

Future releases of the Know your bore application are being planned to allow licensed bore owners to record water meter readings.

The Cohga Weave solution includes all the necessary code and configuration files to develop Mobile Web Applications for searching, reviewing and editing information from all mobile devices – tablets and phones – using their native web browsers. The Weave mobile client makes use of all the existing Weave resources such as maps, data, indexes, searches, etc., meaning mobile web applications can be developed and deployed very quickly.

In addition, all the security associated with an existing Weave system continues to be used which removes the risk and effort of implementing another security protocol.

“Cohga Australia provided a simple and effective mobile web solution that exceeded client expectations. Under an extremely tight deadline, they developed a product that was cost-effective and most importantly, re-usable in other applications. Despite the time pressures, Cohga’s customer service was always polite and solution-focused.

This company has proved themselves to be a leader in spatial systems integration and mobile web development.”

Ross O’Campo, Geospatial Services Branch, Department of Environment and Natural Resources

Know your Bore Web Application

Clicking the Search Button opens the Quick Search tool to enable the user to search for a property or bore. In this case the search term is “Secrett” which returns all the properties in Secrett Road.

Figure 2 – Search Button

Figure 3 – Quick Search

Selecting a property from the drop down list will zoom the map to that property (in this case, 160 Secrett Road) and show the water bores in the vicinity (shown as red, orange, green and blue points). By clicking on a bore the relevant details are displayed.

Figure 4 – Water bore locations

Figure 5 – Details of selected bore

The View report and More information hyperlinks will open new browser pages with additional information.

Finally, clicking the Layers button on the home page presents a set of base map layers under user control.

Figure 7 – User controlled map layers

Positive Outcomes

The launch of the Know your bore tool includes both a desktop browser client and a mobile client. Weave has the ability to determine what platform is being used and serves the relevant client as appropriate.

Since its launch the Department has been monitoring the use of the system and notes that over 90% of access to the site is via mobile devices, which accords with their understanding of current user preferences.

Given that Territorians are the highest water users in Australia and that across the Territory about two thirds of water is used on gardens, it is important to communicate as widely as possible the need for everyone to do their bit to reduce demand on groundwater resources.

By making this information resource available via the Know your bore mobile application the Department has greatly broadened their public reach thereby potentially influencing many more people about the urgent need to conserve water.
