Remote Sensing & Image Interpretation Services

We provide a range of Remote Sensing and image interpretation services that can help any organisation to leverage the benefits from satellite and aerial imagery.

Thanks to government programmes such as Landsat and Copernicus, alongside the rise in commercial drone operations, satellite and aerial imagery is accessible like never before. These resources have helped to open a wealth of data that can be used to unlock information about the health, state and land uses of our planet. By utilising the many available sources of Remote Sensing data, we can ensure that the best available imagery is analysed to meet your specific requirements.

Our team of Remote Sensing Analysts have experience working with multiple imagery sources including many of the most commonly used open source and proprietary Remote Sensing software packages and platforms. If you have a Remote Sensing project you require support with or don't know where to start, get in touch to see how our experts can help.

What is Remote Sensing?

  • What is Remote Sensing?

    What is Remote Sensing?

    Remote Sensing is the observation of objects or areas from a distances, usually from aircraft, drones or satellites, to obtain detailed information about them. The classification and analysis of captured imagery can lead to the establishment of information regarding the surface and subsurface of our planet.

    Remote Sensing techniques open new windows into the unseen world via sensors which detect energy that is reflected from the Earth. The spectral and spatial characteristics of such data contains invaluable information regarding land use and land cover, helping to provide a detailed assessment into issues such as the health of vegetation, the salinity of rivers and streams or lead to the discovery of new sites ideal for mineral exploration.

  • Automation of Remote Sensing Tasks & Processing Chains

    Automation of Remote Sensing Tasks & Processing Chains

    Creation of algorithms utilising multiple platforms to automate the processing of remote sensing imagery.

    Combining data from platforms such as SNAP, Orfeo Toolbox, R, Python & Bash Scripting we can create automated processing tasks including the downloading of Sentinel-1 & Sentinel-2 data, multiple pre & post processing procedures & machine learning classifications.

    The automation of processing chains enables our specialists to work for efficiently with large & complex datasets, helping them to solve problems & support decision making.

  • Atmospheric Correction & Masking

    Atmospheric Correction & Masking

    Ensuring the accuracy of data through the use of atmospheric correction & masking.

    Atmospheric correction involves the process of removing the effects of the atmosphere on the reflectance values of images captured by satellite or airborne sensors. We are experienced in the correction of Sentinel-2 data using Sen2cor & iCOR algorithms, creation & application of cloud masks using IdePIX & iCOR and the creation & application of shadow masks.

    Atmospheric correction ensures that the pixel values sampled by optical satellites correspond to the spectral characteristics of features on the ground whilst masking prevents pixels from adversely affecting the output results.

  • Pre & Post Processing of Imagery

    Pre & Post Processing of Imagery

    Undertaking pre & post processing of imagery to reveal complex information about aspects of the world.

    We specialise in the pre & post processing of optical & SAR data captured from satellites including Sentinel-1, Sentinel-2 & Landsat. Through complex processes such as atmospheric correction, resampling, reprojection, index creation ,texture analysis, change detection & time series analysis, we can produce intelligible information to help support strategic decisions.

    Our highly experienced team of remote sensing specialists are skilled in the use of multiple techniques to help maximise your use of rich data sources.

  • Application of Machine Learning Algorithms

    Application of Machine Learning Algorithms

    Utilisation of machine learning algorithms to produce accurate classifications of remote sensing data.

    Through the use of robust cutting-edge statistical techniques such as K-means, ISODATA clustering, Pixel-based classification, Object-based classification, ground truthing & probability analysis we can leverage machine learning to produce the most accurate classifications of data.

  • Time Series & Change Detection Analysis

    Time Series & Change Detection Analysis

    Observation of geographical features to identify & track changes that occur over time.

    Adding an additional temporal dimension to spatial data analysis, our remote sensing specialists are experienced in using machine learning classifications, time series graphs, time series animations & delineation to improve the ability to differentiate between geographical features & track changes in these features over time.

  • Orthorectification of Imagery

    Orthorectification of Imagery

    We are experienced in the orthorectification of high-resolution imagery to ensure their positional accuracy.

    Using datasets such as WorldView or GeoEye, we can take positionally inaccurate raw remote sensing data & correct it to ensure each pixel corresponds to its exact location on the earth's surface.

  • Image Index Creation & Application

    Image Index Creation & Application

    Enhance the information obtained in features from remote sensing imagery through image index creation & application.

    By manipulating common image indices such as NDVI, PSRI, EVI, BSI, NBR, dNBR, NDWI & MNDWI our remote sensing experts can gain new insights on the state of the planet, from identifying areas scarred by funding or affected by flooding to tracking the health & state of vegetation and crops.

  • DEMs & Associated Products

    DEMs & Associated Products

    Creation of Digital Elevation Models (DEM) in the identification & classification of features & the extraction of height data.

    Alongside the creation of DEMs we are also experienced in the use of Digital Surface Models (DSM), Digital Terrain Models (DTM) and the creation of hillshade, slope & aspect products. Using these various methods, we can extract invaluable information & identify features on the landscape which would be easily missed from standard imagery alone.

  • Feature Extraction & Mapping Outputs

    Feature Extraction & Mapping Outputs

    Extracting features from remote sensing data so they can be easily understood & utilised to deliver actionable insights.

    Through the manipulation of remote sensing data, vectorisation of delineated features, feature documentation, attribute creation & association and map production, our remote sensing experts can help to extract & present feature information that delivers fresh insights to support strategic business decisions.
