Geoimage is experiencing very high demand for Digital Elevation Model (DEMs) purchases, with our Mining, Oil and Gas clients opting to use satellite imagery wherever geospatial insights are required.
Satellite can be considerably less expensive than LiDAR for DEM creation and environmental monitoring. This combined with the benefits of using 8 multispectral bands, DEMs can provide added analytic options for greater insights into your specific project requirements.
Today Geoimage can offer 50cm DEMs with 30cm resolution imagery, from anywhere around the globe, and the capacity to capture will soon double following the commercialisation of DigitalGlobe’s latest high-resolution satellite imagery by WorldView-4.
Geoimage's Geospatial Processing and Technical team specialises in DEMs creation derived from either archived stereo imagery, or can task a satellite to custom collect stereo data specifically over your area of interest. This speed of capture and the amazing accuracies obtained is good news for clients requiring detailed terrain information over any global location.
Some common uses of DEMs include:
- Extracting terrain parameters
- Operations management, identifying pit and stockpile changes
- Calculating topsoil clearance and remediation requirements
- Modelling water flow or mass movement (for eg. landslides, wall collapses)
- Orthorectification of aerial photography or satellite imagery
- Terrain analysis in geomorphology and physical geography
- Engineering and infrastructure design
- Line-of-sight analysis
- Base mapping
- Hydrological modelling – flood mitigation or watershed analysis
- Environmental change application
- Risk assessment.
DEMs can be delivered to you either as a Digital Surface Model – including vegetation, buildings and more, or as a Digital Terrain Model – removing trees and buildings to deliver a “bare earth” model. Multiple DEMs can also be compared to identify changes in volume, for example, stockpiles, tree canopy cover, pit size and clearance, and more.
Digital Elevation Models are an integral part of any geospatial analysis. Some of the benefits of using satellite imagery, include:
Geoimage are experts in creating all types of DEMs from satellite imagery suited to your specific needs and requirements.

In support of UNESCO's International Day for the Conservation of the Mangrove Ecosystem today, Geoimage presents this case study on the Classification of Mangrove Species: Application of Earth Observation satellite imagery in the monitoring and conservation of Mangroves.
This case study utilising WorldView-3 imagery showcases a robust, non-invasive, cost-effective, reproducible, consistent and un-biased strategy to monitor and preserve the very fragile and important environments that are mangrove habitats.
|Challenge:||Provide an indication of rehabilitation success of an adjacent mangrove habitat, potential impacts to nearby mangrove forests and comparison to control sites growing within the same region.
||Mapping and analysis of plant groups at species level.|
|Method:||Use archived imagery collected by the WorldView-3 satellite in 8 discrete wavelength bands at 2m resolution and one broad wavelength band at 50cm resolution.|
|Location:||Four discrete mangrove habitats within a 50sq km area were investigated.
||Reduced the need for extensive, lengthy and expensive field visits.
Un-biased and stable dataset allowed our client to limit the number of training and calibration sites required for consistent mangrove monitoring.
Minimizing operational costs, the application of remote sensing technology reduced the need for associated health and safety considerations and minimized the potential for injury and lost time.
Detailed Case study
This case study is the Classification of Mangrove Species by Geoimage, wherein we demonstrate how Earth Observation Satellite imagery can support and protect one of the world’s most fragile and important ecosystems.
Earth Observation satellites have been collecting imagery since the launch of ERTS-1, renamed Landsat 1, in 1972 and hence, there is a significant archive of imagery for many applications, including visual inspection and interpretation, analysis, extraction of information, change detection and land cover classification. Since the launch of the first very high resolution (sub-metre) sensor in 1999, Geoimage has had the ability to apply these types of investigations at a much higher detail, such as mapping and analysis of plant groups at species level.
The project described herein uses archived imagery collected by the WorldView-3 satellite in 8 discrete wavelength bands at 2m resolution and one broad wavelength band at 50cm resolution.
Many industrial and commercial businesses that adjoin mangroves, particularly where damage has occurred, have a regulatory requirement to offset (by coordinated planting), rehabilitate and monitor these environments.
This project was undertaken to provide an indication of rehabilitation success of an adjacent mangrove habitat, potential impacts to nearby mangrove forests and comparison to control sites growing within the same region. The rehabilitation process involved the planting and monitoring of two mangrove species i.e. Rhizophora stylosa and Avicennia marina.
The described application of remotely sensed satellite imagery and analysis of same provided several advantages compared to that of ground based monitoring investigations and can be considered as a useful tool in the characterization, assessment of environmental impacts and ultimately the preservation of mangrove forests, whether these be naturally occurring or planted.
Benefits to the environment
Mangroves are an important part of estuarine ecosystems and wetlands and are protected in many Australian jurisdictions. Specifically, under Queensland legislation all marine plants (including mangroves) are protected under the Fisheries Act 1994. This act prohibits the destruction, damage or disturbance of marine plants without approval from the regulator.
Due to the importance of mangroves, monitoring is an important means of characterisation allowing determination of composition, health and distribution of forests. This information can be used to compare status and identify trends and provide information useful in environmental impact assessments.
Application of emerging or developing technologies
The application of remote sensing for monitoring mangroves has significant advantages to that of traditional manual surveys.
Information can be gathered in a non-invasive manner and provides greater objectivity (the data is quantitative) by removing subjectivity of assessors on the ground. In addition, remote sensing techniques have a great potential for reproducibility and consistency across discrete and adjacent areas of investigation. Satellite imagery is also able to cover greater spatial areas, removing sizable coordination and costs associated with labour intensive manual surveys.
Unlike traditional surveys, sensors such as WorldView-3 collect information in wavelength ranges of the electromagnetic spectrum that lie outside of the visible range. The discrete spectral responses of the 8 bands on WorldView-3 to different land cover types allows a more robust classification and provide a greater sensitivity to the mangrove species varieties. In addition, the near infrared bands can be used to provide insight into vegetation attributes such as plant health or vigour, which may also be used in the classification criteria.
Whilst not unique in its application for scientific studies and similar selected applications, WorldView-3 8 band imagery provides great potential in mainstream markets for environmental monitoring through a combination of high spatial resolution and spectral capability. This allows for greater differentiation of features for purposes of identification, classification and improved characterisation.
Finally, the availability of an extensive data archive allows for the investigation of temporal changes and trends over a regional or localized landscape and potentially further calibration and qualification of results.
