Overview
Gen 4 is powered by a new raster model with the addition of eight new AI Layers for roof condition and construction. Gen 4 also improves existing layers already available in Gen 3. Open World vectorisation has been expanded, enhancing some existing AI Packs and adding new ones. Gen 4 processing includes every survey from mid 2020 to present, and coverage now extends beyond Australia and the USA to include Canada and New Zealand.

1.2 |
This upgrades all previously processed data from gen4-lightning_bolt-1.1 to gen4-lightning_bolt-1.2. | ||
1.1 | New fields "clippedAreaSqm" and "clippedAreaSqft" added to all feature classes behind AI Feature API.
This upgrades all previously processed data from | ||
| Uses the same raster model and vectorisation process, such that results will be identical to Available on surveys processed from July 2021 onwards | Poles - Introduces a new feature in the data that captures the location of both power and light poles as a point feature with attached metadata. | Building Footprints introduces a new fidelity score for both building footprints and roof outlines along with confidence as a measure of quality. Roof Condition now includes a "low confidence roof condition" attribute for each of the five roof condition layers. The low confidence roof condition will describe a larger area, and a lower confidence than the standard one. Given roofs typically degrade gradually, this makes it easier to identify new roofs with no weathering at all (e.g. for tile and shingle staining), but has a much higher rate of false positives. |

Coverage
The big new change to coverage with Gen 4 is adding New Zealand and Canada to our coverage footprints. Initial coverage for Gen 4 is every survey captured in all four capture countries from mid 2020 until launch in May 2021 (and ongoing).
The one key caveat to New Zealand and Canadian data is that AI Offline Parcel is not yet available (that is, raster and vector can be provided, but summary information trimmed to property boundaries and address information are not yet available).
New AI Packs
Roof Condition
The Roof Condition AI Pack includes these 5 layers visualised in MapBrowser, and AI Feature API + AI Offline vectorised data that intersects these with our building footprints. Roof Condition layers include:
Enhanced AI Packs
Surfaces | Water Body raster and vector has greatly improved performance. |
---|---|
Construction |

Swimming Pool | Swimming Pool raster and vector has improved performance. |
Solar Panels | Solar Panel raster and vector has improved performance. |
New AI Layers
The Gen 4 model (gen4-building_storm-1.0) introduces a new raster model with eight new layers to the AI Layer Glossary. Some of these have not yet been included in generally available AI Packs from the first release of Gen 4, but will be subsequently added to existing and new AI Packs:
