High Definition Land Cover Mapping - LandBase™
The environment around us continues to change but how. How much land is covered with artificial surfaces? How much forest covers the land? Answers to these questions and others can help environmental and habitat management, change detection, flood modelling, infrastructure planning and more.
To support these applications Infoterra has produced LandBase™ a high definition land cover mapping product.
This new land cover product is a vector map produced using the latest digital aerial imagery and object based classification technology. This has enabled the production of land cover classifications to the highest resolution, accuracy and extent, available on the market today.
LandBase is designed as a framework, for used within a GIS system, to allow specific spatial queries—what percentage of this area is covered by trees—as well as allow the addition of further detailed classifications.
- Provides unrivalled land cover resolution—to property level/1:5000 scale
- Enables creation of custom solutions to enable higher level analysis
- Compatible with existing land cover products
- Allows 3D analysis as height information built-in
- Enables cost effective thematic mapping
- Allows spatial analysis of specified area
Classifications
LandBase features two levels of land cover classification.
| Level 1 | Examples | MMU |
| Aquatic | Open ocean, inland water, marsh, fen, inter-tidal zone | 1 ha |
| Cultivated & BUA | Agricultural land, towns, villages & cities, transportation networks, extraction sites | |
| Natural & Semi-natural | Ancient forest, moorland, mountainous regions, coastal margin |
| Level 2 | Examples | MMU |
| Sea & Estuary | Open ocean, estuary | 50m2 |
| Inland Water | Rivers, lakes, canals, ponds | |
| Artificial Surface | Tarmac, concrete, paving, gravels, construction, extraction sites | |
| Bare Ground | Inland rock, coastal rock, sand, exposed soil & very sparse vegetation not part of a cultivation cycle | |
| Buildings | Buildings, monuments, bridges, raised transport, large pylons | |
| Herbaceous Vegetation | Grasses, ferns, cereals, brassicas, root crops, legumes, horticulture, exposed soil & very sparse vegetation clearly part of a cultivation cycle | |
| Sub-shrubs | Dwarf shrubs, heathers | 1 ha |
| Shrubs | Bushes, hedges, gorses & immature trees, mean height typically below 2m | 50m2 |
| Tall Shrubs & Small Trees | Tall bushes, small trees such as apple, new plantations, mean height typically 2-5m | |
| Trees | Mature broadleaf & coniferous trees, mean height typically greater than 5m |
NB. LandBase™ is created using; colour infra-red (CIR), aerial photography (RGB). digital surface model (DSM) & digital terrain model (DTM).
