Satellite Images and Elevation
With access to a huge, up-to-date global archive of satellite images and the ability to acquire new images and elevation models, Hatfield Consultants can deliver the base mapping information your project needs. We work with the leading global suppliers to ensure quality and timely delivery of images and elevation products.
All our satellite image products are delivered ready for seamless integration into your geographic information system, AutoCAD software, or other planning tools. Web-based delivery and image streaming services are available. We can also extract information such as land cover and provide change detection services for environmental monitoring.
Elevation models are custom-made and are ideal for mineral, geo-thermal, oil and gas exploration, or other development in regions where elevation data are lacking and where getting a plane in the air or a team on the ground is too costly, time-consuming, or unsafe.
Based on your project needs, we help design the best image and elevation solutions, including the following:
- Explaining the full range of options available and recommending solutions
- Performing satellite image archive searches and planning new acquisitions
- Designing and delivering monitoring services and image subscription packages
- Processing satellite images with terrain correction, atmosphere correction, and enhancement to ensure they display data clearly and accurately
- Classifying satellite data to deliver information you need, such as maps of land cover and land use, habitats, and wetlands
- Detecting change in multi-temporal images, such as flooding, deforestation, and other disturbance
- Providing elevation models, including ‘bare earth’ terrain
- Processing options to enhance the elevation models with correct hydrological flows, road flattening, contours, or shaded relief
High-resolution satellite images
With a level of detail equivalent to aerial photos, high-resolution satellite images provide precise information for projects over a range of sectors, including mining, oil and gas, renewable energy, infrastructure, and plantation, as well as for detailed land cover mapping and habitat assessment. DigitalGlobe satellites provide spatial resolution from 50 cm to 1 m with natural colour and colour-infrared spectral band combinations. More information is available for each sensor below, or contact our regional order desks to speak to an expert about your needs.
Medium-resolution satellite images
Our solutions include images for mapping and monitoring large areas at a very low cost – ideal for mineral and forest carbon projects, and regional land cover mapping and monitoring by governments and international organizations. RapidEye provides 5 m spatial resolution with natural colour and colour-infrared spectral band combinations. More information is available for RapidEye below, or contact our regional order desks to speak to an expert about your needs.
Detailed elevation models
Detailed and precise elevation models are available with different options for vertical accuracy and grid resolution that can fit most project elevation needs – pricing is typically cheaper than airborne surveys. Elevation product absolute height accuracy varies from 8 m to 2 m – relative accuracy from 5 m to 1 m. Grid spacing is from 8 m to 2 m. The vertical and horizontal accuracy depends on the ground control available, but depending on our global library of ground control points you may not need to provide any ground control information at all. You can purchase elevation data separately or bundled with ortho-imagery.
Regional elevation models
Regional elevation models are custom-made from stereo radar satellite data and global delivery is reliable regardless of relief characteristics or weather conditions – there is no need for ground control points. Astrium Elevation10 products offer up to 5 m absolute height accuracy – relative elevation accuracy is 2 m – at 10 m grid spacing. Delivered for a minimum area of 500 square kilometres, these products are ideal for mineral, geo-thermal, oil and gas exploration, or other developments. Elevation10 is bundled with the TerraSAR-X ortho-radar imagery used to create the elevation model.
