Multispectral Surveys
| |
|
| | The latest from SUMO GeoSurveys, providing a range of aerial and geospatial surveys using drones, known commercially as UAS (Unmanned Aircraft Systems). | |
|
| | One Survey; Multiple Rewards! | |
| | UAS Multispectral Surveys have the capacity to detect sub-surface features with archaeological potential, even on sites hidden beneath crops.
With the crop season approaching, now is the perfect time to book a Multispectral Survey for your archaeological assessment.

| | UAS Multispectral Surveys have the ability to identify sub-surface archaeology via the overlying vegetation. With the capability to survey 100+ hectares in a single day and over landscapes restricted by vegetation - in particular, crops - Multispectral Surveys can greatly inform archaeological assessments, quickly and cost-effectively.
This method can be used to complement geophysical surveys, and even serve as an alternative option when crops inhibit access on to site.

| | A series of raster transformations can be performed using GIS, and interpreted in a detailed report to discuss the findings. Our analysis of the various index models provide a greater scope to identifying sub-surface features. We also conduct an RGB earthwork survey simultaneously to the multispectral to provide base mapping and a richer understanding of the site.
