Contour lines on a vector map represent terrain surfaces derived from the Digital Terrain Models (DTM). Contour lines are created by connecting points of equal elevation on DTMs. These lines provide valuable information about the shape, elevation, and slope of land, allowing users to visualize the terrain's characteristics in a dynamic representation.  

• Unmatched accuracy with intervals up to 1 foot.

Planimetric maps display the horizontal positions or locations of features on the Earth's surface. This includes roads, rivers, buildings, and other objects as they would appear when viewed from directly above, ignoring variations in elevation. These layers are derived from stereo pairs and triangulation, two techniques we use to accurately determine and represent the horizontal positions of features on a DTM. 

Available planimetric features include: 

• Paved and Unpaved Surfaces
• Airports (runways, taxiways, aprons, helipads)
• Railroads
• Manmade Structures
• Water Features
• Water Structures (bridges, dams, etc.)
• Barriers
• Utilities
• Disturbed areas (construction sites, mines, quarries, etc.)
• Landmark features
• Street hardware (signs, billboards, bus stop shelters)

• Vegetation (trees, orchards/nurseries, crops)

L3Harris and their partners are experts in feature extraction, the process of identifying and isolating specific geographic features from high-resolution imagery or data. These features can include buildings, roads, rivers, forests, and other elements present on the Earth's surface. Once identified, these features are delineated and represented as points, lines, or polygons within associated vector layers. We offer a total of 46 vector layers containing:  

• Hydrography
• Industry
• Population
• Utility

• High volume scalability

   

Vector extractions based on VMAP1-2 schema.

Building footprints are extracted from high-resolution satellite or aerial imagery that accurately represent the structure’s outline at ground-level.

• 2D building footprints correlated to multi-resolution TrueTerrain products

• 2D building footprints are available with optional Z-value as Building Height & Elevation Height (MSL) attributes

Visualize every inch of your aerodrome with L3Harris’ high-quality Aerodrome Mapping Databases (AMDB), made from correlated TrueTerrain imagery, DTM elevation data, and vector data—including digital vector maps. Our AMDs are structured GIS datasets that centralize crucial aeronautical and geographical data pertaining to aerodrome facilities and operations. They focus on precise mapping, navigation, and operational support for aviation activities within and around aerodromes, and comply with all industry guidelines and recommendations. Their many benefits include: 

• Real-world consistency allows users to familiarize themselves with the aerodrome
• Can be used in ground-based operations management and on-board aircraft systems

• Enhances safety and situational awareness

• AMDB layers are derived from satellite imagery, which has been georeferenced using survey ground control points. Key airport features are digitized from the georeferenced imagery, resulting in location-specific point, line, and polygon vector feature classes.
• AMDB layers are organized into 5 categories related to their function within the aerodrome: Runways, Taxiways, Aprons, Vertical Structures, and Other Data.

• Detailed attributes are added to vector objects using image interpretation, publicly available airport diagrams, and customer-provided data. This attribution provides additional information beyond the spatial location, allowing the user to access specific details relating to the characteristics and function of aerodrome features.
