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:
“The future’s not faster cables, it’s NO cables” – NuSkope
“Wireless broadband delivers gigabit speeds to residents and businesses now” – Uniti Wireless
“Satisfy your need for speed without the NBN!” – Lightning Broadband
Planning for the point to point links requires detailed knowledge of the line-of-sight since propagation at these frequencies (2.4GHz, 5.8GHz and 24GHz) can be very sensitive to clutter and multi-path interference. Aerometrex provides detailed (50cm cell spacing) Digital Surface Models for Adelaide and Melbourne Metropolitan Area to all the players in the Wireless Broadband segment. We helped Uniti Wireless build a web tool for their customers to analyse the feasibility of receiving a connection as well as an internal tool for planning deployment of new towers.
Adelaide, Melbourne and Mt. Barker datasets (7280 sq. km., 122GB binary data) were ingested into a PostgreSQL/PostGIS database, indexed and stored procedures built to extract full-resolution transects 10km long in less than 1second. Performing line-of-sight operations requires reprojection to ENU (East-North-Up) projection relative to the location of the tower. Algorithms were built reproject from MGA Zones to ENU per analysis and calculate LoS and Fresnel zones. The availability of the accurate DSM and associated rapid/scalable analysis tools has enabled the wireless service providers to expand rapidly and cover most customers with the most efficient placement of towers.
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 and volume calculations of material lost due to erosion.
A test site was chosen near Darwin, Northern Territory, Australia. The area known as Nightcliff has been featured in the voyage of the Beagle and is the site on the Nightcliff market of Sundays. Thus the area is of historical and social importance. This area has had a lot of cliff loss due to erosion and a coastal management plan has been put in place to construct a sea-wall along the foreshore. Datasets captured in 2014 and 2016 clearly show these changes and provide quantitative displacements, which can be calculated using Hausdorff distance algorithms on the reconstructed meshes. A plot of the displacement can be seen in the image below.
AEROmetrex provides aerial photography and mapping services across Australia and beyond. During hundreds of flights and thousands of hours in the air way we’ve amassed a large collection of high quality oblique aerial images that we’re now making available for you to buy in digital format.
The scenic images cover capital cities throughout Australia along with numerous smaller towns and remote locations along the coastline, including Broome, Townsville, Gold Coast, Newcastle and Caloundra. We’ve even gathered images from across the Tasman in New Zealand. From the tallest skyscrapers to pristine beaches, from the dry red dust of the north-west to the lush green parklands of Adelaide, we have something for everyone.
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 well as the foreground focus of attention.
In July 2012 I attended the ESRI International User Conference in San Diego and assisted a UAV manufacturer on their trade exhibit, fielding questions from potential customers of this technology. It was a revelation, not only because of the technology, but because of the reaction of the punters. I could see it in their eyes. Everyone wanted to do this for a job. “Get paid to have fun? I’m in!” Read more
Aerometrex, a CASA-registered UAV operator, announces the implementation of a new AV imaging service with revolutionary performance.
Aerometrex is pleased to announce the introduction of a revolutionary new aerial imaging service based on new technology recently released by Microsoft. The system is offering performance far in excess of current UAV aerial imaging systems in the market with unparalleled efficiency and lowest cost per unit area. Read more
It has been a few years since the tragic days of 2010-2011 when earthquakes almost flattened the beautiful city of Christchurch – New Zealand. A few documentaries have been made and the story of the people captured.
The model below captured using photogrammetry is a time capsule of how the city looked shortly after the earthquakes ( January 2013).
We are in the process of generating an aero3Dpro virtual 3D city model of Adelaide CBD.
In this post you will find a collection of aerial oblique imagery of new building developments as well as other interesting architectural, heritage buildings within Adelaide CBD.
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 interactive navigation capabilities similar to a video game. In the other hand, maps are the core component of many video games and can be based on either fantasy or real-world information derived from geospatial data. A growing number of games developers have also started to use 3D assets generated using 3D photogrammetry techniques. Read more
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 risk. Read more
