Industry Solutions : Environmental Monitoring

Environmental sciences and awareness has expanded exponentially in recent times.

This trend has been justified by alarmingly decreased natural habitat and degraded land. Environmental impact studies and assessments have relied heavily on remote sensing and geographic information systems for monitoring and evaluating environmental situations.

GEO Data Design provides large amounts of satellite imagery data at a variety of resolution and accuracy from satellite sensors such as Worldview-1, -2, and -3, GeoEye-1, QuickBird, Pléiades and SPOT6 & 7. Comparing appropriate satellite imagery over time and using innovative techniques such as Enhanced Normalized Difference Vegetation Index (ENDVI) and Normalized Difference Vegetation Index (NDVI) environmental planning and monitoring targets can be achieved.

The use of satellite remote sensing allows us to address challenges like climate change, water scarcity, crop diseases, soil erosion, by monitoring wind erosion, waterlogging, mapping crops and predicting salinity.

With advanced GIS software like Geomedia from Hexagon Geospatial, 3D modelling and spatial analysis can assist environmental users in making up to date, informed decisions regarding our planets most valuable resources.
