What is land and terrain data?
Features of land and terrain data
Granular land cover classification
Generate detailed insights into both natural and manmade land cover types, supporting habitat mapping, environmental analysis, and land management.
Comprehensive land use mapping
Access geometric representations of land use sites—such as schools, hospitals, and residential areas—to assess human activity, development patterns, and site access.
Elevation and gradients
Elevation and gradient data supports flood modelling, infrastructure design, and landscape visualisation.
Accurate area and access insights
Calculate land area estimations, visualise access points to major sites, and analyse land cover breakdowns for statistical and planning purposes.
Flexible land feature types
Work with five distinct feature types — Land, Land Point, Landform, Landform Line, and Landform Point — for versatile analysis and integration with other datasets.
Sector-ready intelligence
From urban planning and environmental monitoring to emergency response and infrastructure design, our land and terrain data delivers actionable insights for a wide range of sectors.
