We are happy to announce a new and improved generation of our AI content which comes with the following features:
New Neural Network Architecture
Highly customised, multi-scale semantic segmentation architecture loosely inspired by DeepLab v3. You can read about DeepLab v3 here. By investing in our own in-house neural network architecture, we've managed to achieve substantial performance improvements across many of our AI Layers, most notably for large buildings, that were not possible to achieve with standard "off-the-shelf" architectures.
Improved Performance
- Greatly improved raster and vector for commercial and industrial buildings (warehouses, concrete roofs, etc.). Gen 2 is now fit for purpose for C&I building use excluding downtown and CBD areas.
- Greatly improved recognition of Construction Site.
- Improvement in all Roof Materials (particularly tile and metal).
- Improvement in Solar Panel, Swimming Pool and Trampoline.
- Raster smoothing during AI Layer visualization for all layers except for Building, to reduce artefacts (but preserve sharp corners of buildings).
- Identical vectorisation process to Gen 1. Performance improvements are all due to improved raster AI Layers.
Processed Dates and Coverage
- Updated US data set (Spring 2020 season, and select other coverage).
- Note that as well as more recent data, Spring 2020 is majority leaf-off, which improves ability to recognize buildings, pools and trampolines under heavy tree cover in the USA.
- Updated AU data set (latest published as at June 2020).
- Other coverage available on request. Contact your Nearmap Account Manager.
