Microsoft Vexcel UltraCam photogrammetric digital aerial mapping cameras are the source of the best high resolution imagery in the world.
In this short video, we explain how AEROmetrex is taking advantage of UltraCam digital aerial sensors to provide quality aerial photography and photogrammetric mapping.
Situated in Victoria, 210km from Melbourne, Mt Buller is a mountain in the Australian Alps. The village situated near the the summit is primarly a resort town. Mount Buller is popular with snowsports enthusiasts in winter.
This 3D animation has been generated using a 30cm orthophoto mosaic draped over a 50cm digital terrain model.
The gap between these two usually complementary mapping technologies is getting smaller as both satellite and aerial imaging systems have benefited from great technology improvements in the last decade. These technologies can even overlap in terms of resolution, meaning that issues such as accuracy, acquisition and processing time need to be taken into account . It is more of a challenge to make informed decisions about which technology to choose for a mapping project. Nevertheless, each technology is alive and well and possess unique characteristics and strengths which need to be highlighted. Read more
A Digital Elevation Model (DEM) is generally a file containing elevation values representing the terrain height over a specific area of the earth. A DEM can be a raster file: in this case each record is a 3-dimensional element usually associated with geographic coordinates at a fixed grid interval. The denser the grid, the more information the digital elevation model will possess and the more variation in the terrain will be recorded. A DEM with an irregular grid is called a TIN DEM (Triangular Irregular Network) and can be the result of direct 3D point measurements. Read more
Wilpena Pound is a natural amphitheatre of mountains located 429 kilometres north of Adelaide, South Australia in the heart of the Flinders Ranges National park.
High resolution images from multiple sensors can be combined with digital elevation information derived from photogrammetry, Lidar, Radar to produce detailed 3D visualizations and fly-through. The fly-through below has been generated using a 70cm digital aerial orthophotography wrapped over a digital elevation model. Read more
