Satellite Vegetation Monitoring

Environmental concerns give rise to a growing need to monitor the current and future states of forestry, vegetation and agricultural assets. Our forestry and vegetation products provide powerful management tools, delivered in a common and reliable format.

 

Background

Earth observation (EO) satellites offer the opportunity to monitor vegetation assets entirely remotely. Large areas can be covered at a single moment in time, providing a consistent snapshot over wide areas. TCarta’s team of remote sensing scientists has experience monitoring a wide range of green assets for agriculture, food security and environmental applications. Our outputs have been used by decision makers, agronomists, scientists and land owners to better understand their resources and efficiently plan and manage their daily activities.

We have experience in delivering data related to mangroves, farms, forests, and recreational areas. If your work involves vegetation of any kind, then contact us today to understand how our data can improve your efficiency and day-to-day activities.

Mangroves

Mangroves are recognized as a crucial resource within the coastal and intertidal environment. They act as a natural barrier from storm surges and coastal erosion. They form a critical nursing ground for fish spawning, and they are a natural carbon sink.

Mangrove forests are ecologically important in the context of Carbon sequestration and contribute significantly to climate change mitigation. Sea level rise, escalating atmospheric CO2 concentrations, global surface temperature increase, and human development in many coastal regions; along with varying water characteristics, including changes in salinity, pollutants, and sedimentation all contribute to the health and extent of mangrove ecosystems. For these reasons it is important that Mangroves are appropriately monitored.

TCarta has experience in monitoring multi-temporal changes in mangrove extents and quantifying the health of mangroves using a variety of different multi-spectral satellite images, including Landsat and WorldView images.

Crops and Farms

Satellites offer the opportunity to provide significant additional intelligence to farmers, agronomists, food suppliers, insurers, governments and other end users with interests in the agriculture sector.

TCarta’s Team has experience in using satellite image analysis and remote sensing techniques to provide frequent information regarding crop health and status. Remote sensing outputs have been customized to clearly illustrate statistics that assist in agricultural management. Agriculture monitoring services have been deployed at varying levels of detail from farm, field, parcel to individual plants.

TCarta’s crop and farm monitoring products and services are assisting multiple end applications including:

  • Improved efficiency of water use;
  • Increased understanding of crop yields by specific location, contributing to better farm management;
  • Implementation and management of distribution of subsidies by governments and authorities;
  • Monitoring for violation in agricultural land use;
  • Managing the food supply chain through forecasting food yield and supply.

TCarta provides location based agriculture services that are driven by satellite imagery. Customers have received data that can be immediately integrated into their GIS systems. TCarta also provides complete agriculture management platforms that are customized to the end user’s specific requirements.

Trees and Forests

Earth observation satellites allow forest stands as well as individual trees to be mapped and monitored. The TCarta Team works closely with their clients to utilize satellite imagery for forestry mapping tasks. Combining optimal satellite imagery with customized remote sensing algorithms, trees and forests can be accurately monitored to understand health and status.

Leveraging Very High Resolution satellite imagery, TCarta delivers detailed forest inventory databases. DigitalGlobe’s WorldView-2 and WorldView-3 satellites offer the right combination of spatial and spectral resolution for end customers to have a complete understanding of their forests. All eight multispectral bands are processed to identify tree species, with the near-infrared bands being crucial to assess vegetative health.

TCarta’s remote sensing experts deploy a multi-stage workflow that has customized and aggregated several commonly used algorithms to differentiate tree canopies and extract them from various soil conditions. Individual canopies can be captured down to 1m2 in size, and attributed with indicators of health, species and spatial characteristics.

TCarta’s satellite forest inventories have been used to manage and understand both natural and man-made plantations. Low-health classifications have been correlated with their causes (poor irrigation, saline groundwater seepage or insect infestation for example), so that continual monitoring with imagery can pinpoint problems and help dispatch the right solution before trees have died.
