Satellite Imagery

Satellite Imagery

The adoption of satellite imagery and derived products has expanded as the image resolution, spectral sensitivity and positional accuracy has improved. The advent of cloud-based services and other web-based desktop solutions has enabled improved levels of online functionality and peformance without having to host and manage the data. Access to extensive archives of satellite data and highly agile optical and radar sensor constellations support timely acquisition and delivery of data in mono and stereo modes. These faster delivery timeframes are enhanced with an expanding range of value added products enabling more efficient monitoring and mapping of assets.

Common satellite derived products include:

  • Digital Elevation Models
  • ‘Bare earth’ Digital Terrain Models
  • Contours
  • Orthomosaics and rapid mosaics
  • Event extent and status such as flood or fire
  • Vegetation indices
  • Change surfaces and polygons

AAM is uniquely placed to offer a diverse range of delivery mediums and value adding options. The AAM case studies overview some of these products:

  • 30cm - 5m multispectral, high resolution imagery
  • 2m terrain grids
  • 5m country-wide image mosaics
  • cloud penetrating RADAR based flood extent and subsidence surfaces based on detected change

Existing and complementary datasets are often integrated with archival or new capture satellite data. Such datasets include valuable inputs such as existing or new ground control points, digital terrain models, and vegetation status as well as field data which often enhance the positional accuracy and suitability of the satellite data for specific tasks.

The new capture of data can be arranged to align with specific dates associated with an engineering project stage, crop phase, season or regulatory requirement.

Archive data permits rapid access and reduced cost to existing data for baseline studies and retrospective monitoring information. In certain tropical areas multiple archive datasets are combined to build imagery with minimal cloud cover.

DigitalGlobe

digital-globe-aam

DigitalGlobe is a leading provider of commercial high-resolution earth observation and advanced geospatial solutions that help decision makers better understand our changing planet in order to save lives, resources and time. In February 2013, DigitalGlobe and GeoEye merged under the one brand, DigitalGlobe. 

DigitalGlobe imagery is captured by their unique constellation of specialised satellites that feature the world’s most advanced multi-spectral sensors which image at resolutions down to ~30cm.

AAM can request new capture of WorldView-3 across 8 to 16 spectral bands.

WorldView-3 features industry-leading geolocation accuracy, below 5m, enabling the precise mapping of remote areas.

The vast global archive of DigitalGlobe imagery can be readily searched online using ImageFinder to ascertain the dates and capture parameters of imagery available for any area of interest.
 

Contact our team to discuss how we can apply DigitalGlobe’s unique products and services to benefit your project.

RapidEye: high resolution satellite products



RapidEye's broad area coverage, rapid capture and "Red Edge" sensing capability make this information source compelling and valuable. The short re-visit time, facilitated by a constellation of 5 identical satellites,  aids in vital change detection of land based features, assessment of current land use, disaster response, REDD, forestry and agribusiness applications which require current imagery or multiple coverages.


The sensors used in RapidEye's satellites capture images across 5 spectral bands at a spatial resolution of 6.5m. The spectral bands include a dedicated "Red Edge" (690-730nm) band, which is sensitive to changes in chlorophyll content, for advanced vegetation monitoring and analysis.

Customised mosaics and vegetation indices can also be provided from RapidEye's substantial historical archive, a collection of more than 4 billion square kilometres of imagery.

RapidEye imagery can be combined with your new or existing ground control, other image datasets and terrain data.

The vast global archive of RapidEye imagery can be readily searched online using EyeFind to ascertain the dates and capture parameters. Free sample data is available online for a select number of locations.

AAM provides RapidEye data and value added services for projects around the world.

e-GEOS COSMO-SkyMed

The e-GEOS COSMO-SkyMed© constellation is made up of four identical Synthetic Aperture Radar (SAR) satellites that can acquire mono or stereo imagery at any location on the globe at spatial resolutions ranging from 1m to 100m.

Unlike optical earth observation satellites, SAR satellites can acquire imagery day or night and through cloud cover. This capability combined with the COSMO-SkyMed multi-satellite constellation makes it possible to revisit a site daily and ensure that imagery can be acquired during periods of adverse weather.

AAM uses the advanced capabilities of COSMO-SkyMed to support our clients across industries and projects, for example:

  • rapid acquisition for emergency management response to natural weather events;
  • temporal monitoring and analysis of marine and land environments for natural resource management,
  • forestry and agriculture;
  • DEM generation for 3D surface modelling
  • interferometry to assist with detecting land subsidence for mining, oil and gas, and engineering projects.

To discuss how COSMO-SkyMed data meets your project requirements, please contact us so we can review current and archival imagery.
