31 March 2023: Perceptions of Practice survey functionality released
The Perceptions of Practice (AKA social survey) survey developed by the Office of Great Barrier Reef, Human Dimensions team has been implemented within P2R Projector. Perceptions of Practice surveys can be conducted from within P2R Projector at two project stages ‘Initial’ and ‘Implemented’ .
09 December 2022: Minor update for stream sediment
The previous release (04 November 2022), constrained the upper and lower limits of stream sediment generation, resulting in some large reductions in predicted sediment saving from riparian management. The constraints on the upper and lower limits of sediment generation have been expanded, but still exclude unrealistically high sediment generation rates.
A minor fix has also been applied where the donor inkind time field for a project was populated with the inkind cash value when a project was re-opened. The correct mapping now applies.
04 November 2022, Sugarcane Industry method changes
Changes for the Sugarcane industry in this version:
- The method of predicting the nitrogen reduction has changed to a nitrogen use efficiency approach for selecting the underlying modelling simulation
- Predicted nitrogen savings are more sensitive to changes in nitrogen application rates.
- The application of mill mud no longer impacts the project scale nitrogen balance. That is, changing the mill mud application rate in the management practice survey will not result in a predicted change in project level nitrogen saving.
- For stream bank related sediment saving predictions, we have revised down the sediment savings from large streams to be the same as for medium streams.
- The soils layer for grain has had a very minor update to add a missing soil code to a small number of soil polygons.
We have implemented:
- the ‘spatial wrangler’ functionality to help handle large collections with overlapping projects and multiyear reporting.
- a ‘change layer’ functionality to help handle projects that overlap with projects from previous years.
- another export option for those with large collections to report aggregate changes in practice across catchments.
- minor changes to export field formatting to improve compatibility with related data systems.
3 September 2021: Grazing Industry release
First version of grazing industry functionality released. Including pasture management, streambank management and gully management via input of results from the gully toolbox.
Additional functionality changes included in this release that apply across all industries:
- A higher resolution zoom to allow more precise mapping.
- Labelling of submitted project collections with the group they came from.
- Better support for importing of partially completed surveys (e.g. when only the before questions have been answered)
- Explainer page for Delivery Ratios
6 May 2021 Soil mapping for Grain and Banana industry to extend spatial range of results
Paddock modelling simulations for the Grain and Banana industries are not conducted for all soils and management practice combinations in all regions. In order to allow a result to be calculated, P2R Projector maps the next most similar soil type where a simulation exists. No-results cases can still occur where there is not a suitably similar soil type with a modelling simulation.
4 May 2021 Industry level version control update
When anything changes that should require a recalculation at the industry level, then the ‘survey version’ of projects is incremented. The activities that may require a recalculation are revisions in simulations, or changes to soil or climate mapping or management practice survey or weighting changes or delivery ratio changes. When opening or importing a collection, if the ‘survey version’ of any projects in a collection do not match the current ‘survey version’, then a popup will appear, requesting a recalculation.
16 April 2021 - Grain industry V1, Banana industry V2
First release of the grain industry. Covers the Burdekin and Fitzory regions only. Includes fine sediment generation only.
Banana Industry V2
Banana industry version 2 release. based on revised paddock modelling simulation to reflect updated management practice adoption survey. All existing Banana industry projects will need to be migrated to the new version. This migration occurs via an automatic detection of version when a collection is selected. A popup prompts migration.
Sugarcane Schema alignment
Question 13 of the sugarcane management practice survey was inconsistent with the numbering schema used in the Collector App. Specifically, P2R Projector had no Q13.2 response.
16 February 2021 App V3, to reef delivery, Cane simulation values update
App Version 3
P2R Projector has been completely rebuilt and released in this major version update.
Delivery to reef
All reported water quality savings are savings at end of system. This is achieved by applying a constituent specific delivery ratio for each underlying SORCE subcatchment. The delivery to stream values can still be determined from the detailed results download which includes the constituent delivery ratio which can be used to back-calculate the delivery to stream.
Sugar Cane industry update
The underlying sugarcane simulation yield values where revised to reflect delivery to stream. The previous version was edge of paddock delivery and significantly overestimated yield in some locations.
The ability submit collections to other groups added.
Oct 2020 Sugarcane NUE calculation update
Minor change to correct an error in NUE calculation.
August 2019 Sugarcane V2
Sugar cane Version
New version of sugarcane modelling simulations conducted to reflected updated management practice adoption survey.
Mini-survey to aid migration
Mini-survey added to reporting table to allow batch changes in survey response for migrating surveys from version 1 to version 2 surveys
Project management functionality
Added the ability to manage projects such as splitting projects by block, copy, delete
September 2018 V1 Banana industry released
V1 of the Banana industry released
August 2018 Version 1 release
Sugar cane industry
Version 1 of P2R Projector includes the sugarcane industry.
