Using metropolitan scale Digital Surface Models for wireless network coverage analysis

The slow propagation of the NBN and the constant demand for high bandwidth services such as Netflix, Stan etc. has created a niche for high bandwidth point to point links and wireless DSL providers. Here are some of their taglines:

Quantitative Coastal Erosion Monitoring using Photogrammetry

Aerial and Ground based Lidar and photogrammetry have been used individually and in combination to monitor coastal erosion. We have developed our oblique photogrammetry with multi-ray matching technique to a point where these methods can be replaced by a single dataset captured using Aero3dpro methodologies. With accurate survey control multiple epochs are exactly aligned and suitable for displacement analysis … Read the rest

20 Things They Don’t Tell You About UAVs

The energy, enthusiasm and the inventiveness that is going into UAV* technology these days is truly remarkable. There has been a proliferation of manufacturers, suppliers, users and conferences promoting the technology. We have all seen stunning video clips and images taken from UAVs – the low altitude aerial perspective enables unique views of a wide sweep of surrounds as … Read the rest

Geospatial and  photogrammetry: When the mapping world and the gaming world collide

The gaming and the mapping world might look like two very distinct industries but when we give a closer look, we can discern some similarities. Both industries are now more than ever benefiting from each other’s unique features. In one hand, interactive 3D GIS are now using improved graphics, atmospheric and particles effects to visualise real-world data as well as … Read the rest

Coastal erosion mapping using 3D photogrammetry

Coastal erosion is the wearing away of land along the shoreline due to the natural removal of beach or dune sediments caused by wave action, wave and tidal  currents, high winds, drainage and other human-induced causes of erosion . Rising sea levels, more frequent storms and cyclones are also increasing coastal erosion and are putting infrastructures, properties and people at … Read the rest

Virtual 3D city models: A base dataset for Australian States departments and local councils

An increasing number of Australian states government departments and local councils are using or are in the process of acquiring virtual 3D city models as part of their planning and development strategy. In addition to other geospatial information layers integrated into interactive 3D GIS solutions such as Skyline TerraExplorer, these new tools provide intuitive and innovative ways to communicate complex … Read the rest

Photogrammetric Modelling of Cars for pedestrian impact simulation

  The CASR Lab does extensive head-bonnet collision testing to assess new car models entering the market for safety.  The limit of deformation of the car’s hood is determined by the gap between the hood and the engine block. Measuring this gap requires extensive 3D modelling of both the hood and the engine block and experimentally testing the deformation at all … Read the rest

Integration of 3D streetview earthmine with interactive 3D GIS Skyline Terraexplorer and aero3Dpro city model as a base dataset

Integration test of 3D Street Level Imagery Solutions earthmine into Skyline Terraexplorer pro.

The 3D base dataset is a virtual 3D city model of Karratha, WA generated with aero3dpro.

Users can navigate in the earthmine window and the corresponding location will be displayed into Terraexplorer in real-time.

Users can also pick up a location on the virtual 3D model and … Read the rest

Systems for acquiring Oblique Aerial Imagery

Oblique imagery got thrust into the spotlight with Microsoft’s publication of the Bird’s Eye imagery to the public. Geo-referenced oblique images are useful for highly automatic creation of 3D city models on their own or in combination with airborne Lidar and planar topographic maps containing building outlines. With the advent of multi-ray matching algorithms using rotation invariant features such as … Read the rest
