<img src="Landmask.png" alt="Landmask for water monitoring ">

LandMask is a geoservice that explicitly masks land and other non-aquatic components, such as vegetation, snow and ice, from water in each selected image, thereby leaving water areas unmasked for visual assessment and further analysis. Use it to improve the accuracy of your land change analysis over time.

Product Description 

LandMask provides fundamental information on characteristics of the land-water interface, and by masking the land itself, creates a baseline for the further assessment of coastal water properties and habitat conditions, which are essential for human health and welfare, coastal resource use and development, and environmental sustainability.

This service benefits all agencies and companies in need of reliable, repetitive, and low-cost information for coastal change assessment, water quality, ecosystem status, or other aquatic and coastal investigations.

LandMask is a robust multispectral index that performs well for most conditions. The monitoring is based on Landsat-8 and Sentinel-2 satellite images; each suitable Landsat-8 or Sentinel-2 data set that was acquired within a specified time period will be analyzed. Known limitations include imagery with high cloud cover or confusion of water areas with dark surfaces and shadows.

Output files are provided in standard GeoTIFF and Shapefile formats. They are ready for immediate visual interpretation and direct incorporation into reports, presentations, or for further analysis.

Product details 

Monitoring is based on Landsat-8 and Sentinel-2 satellite images. The resolution of the satellite determines the resolution of the resulting map. The revisit time of 5 days for Sentinel-2 and 16 days for Landsat 8 define the maximum update frequency. Whenever an image take is available over a selected area, and the cloud coverage is below 20%, a new LandMask is generated. On average, biweekly or monthly updates will be available.

The LandMask package consists of the following output files:

  • LandMask image (GeoTIFF)*
  • LandMask shapefile (Shapefile)*
  • True-color RGB base image (GeoTIFF)*
  • LandMask layered on RGB base image (GeoTIFF)*
  • Grayscale LandMask layered on RGB base image (GeoTIFF)*

*All output files are distributed as single integrated ZIP file

Please note 

Beyond the standard options, custom configurations are possible. Just contact us.

  • Volume discounts for larger areas are available.

Pricing / Licensing 

The pricing is based on the size of the selected area, the selected resolution, and the length of the monitoring period. The calculated price is valid for usage by one named user. cloudeo Terms & Conditions apply.
