Remote Sensing Services
Satellite and airborne remote sensing provides a unique perspective of the Earth’s surface and can be an invaluable tool for landscape assessment and monitoring, a vital step in the planning process.Satellite Imagery
The increasing availability and decreasing price of satellite imagery acquired at moderate (30m) to very high (0.6m) spatial resolutions makes remote sensing a cost-effective solution for mapping and analysis at both landscape and regional scales. Moreover, the increase in spectral resolution (i.e. more wavelengths than are visually detectable) can provide a wealth of information about subsurface archaeological or geological features, crop marks, soil moisture, vegetation vigour, etc.
Aerial Photography
Aerial photography (both historic and current) can also provide useful information about the cultural and natural landscape at a much higher resolution (0.5m and higher) and is particularly well-suited for detecting archaeological features.
LiDAR
Other, non-optical sensors, such as airborne LIDAR (LIght Detection And Ranging) can provide extremely high-resolution elevation data for 3-Dimensional landscape analysis.
Easily combined within a GIS environment with other spatial (and non-spatial) data, remotely sensed data can be hugely useful for landscape characterisation and analysis.
L – P : Archaeology’s experienced consultants provide a wide range of services for processing and extracting information from remotely sensed data.
We can not only help you locate and acquire data to meet your project’s needs, but also provide a full range of processing services for any kind of digital panchromatic, colour or multi-spectral data including:
- Scanning of analogue photography (e.g. historic airphotos)
- Georeferencing
- Orthorectification
- Image enhancement (pan-sharpening, resampling, atmospheric correction, histogram matching, colour/grayscale balancing, etc.)
- Mosaicing
In addition to these basic image processing tasks, we also provide specialised processing procedures for analysis and information extraction, such as:
- Land use/land cover classification and mapping
- Land use/land cover and coastal change detection
- Extraction of specific cultural or natural features (vegetation, crop marks, soil moisture)
- Normalised Difference Vegetation Index (NDVI) classification
- Environmental monitoring
All of the above products and services can also be provided in a fully-customised GIS environment that will allow you (or our consultants should you need assistance) to view and analyse imagery together with your own datasets (e.g. cadastral mapping, proposed development plans, SMR/NMR data).
