Four Property Location Information Products to Enrich G-NAF (Address Database) in Australia

2020-10-03T00:48:42+10:00April 21st, 2020|APIs, Apps, Asset Management, Australia, Elevation, Exposure, Geospatial Big Data Analytics, Insurance, Location Intelligence, Property Information, Real Estate, Risk|

21 April 2020 Geocoded National Address File (G-NAF) is Australia’s authoritative, geocoded address database. It contains more than 14 million physical address records (e.g. residential, commercial and industrial), each having spatially-explicit geocodes such as latitude/longitude coordinates. G-NAF, developed by PSMA Australia, has been available since 2004. A public version, Open G-NAF, has become [...]

New Tile Maps on Terrain and Hydrology: Part 3 (Increasing Details)

2020-10-03T00:48:56+10:00December 9th, 2019|APIs, Apps, Australia, Emergency, Exposure, Flood, Geospatial Big Data Analytics, Insurance, Location Intelligence, Property Information, Risk|

9 December 2019 LiDAR point clouds can represent 3D features very accurately, but due to their large data sizes, point clouds are commonly turned into easy-to-use DEMs at various spatial resolutions (e.g. 1m, 5m or 10m). Such DEMs are increasingly available via government web portals. The vertical accuracy of 1m-resolution Lidar-derived DEMs [...]

New Tile Maps on Terrain and Hydrology: Part 2 (Extending Coverage)

2020-10-03T00:48:58+10:00December 9th, 2019|APIs, Apps, Australia, Emergency, Exposure, Flood, Geospatial Big Data Analytics, Insurance, Location Intelligence, Property Information, Risk|

9 December 2019 Many of us work with elevation data (e.g. LiDAR point clouds and Digital Elevation Models - DEMs) on a daily basis. Nowadays there are an increasing number of government sources for open elevation data, including high-quality, LiDAR-derived DEMs. As we have recently introduced (link to the previous blog), elevation data [...]
