Conceptual Consistency

The data is consistent with respect to the visual representation of ground and non-ground features, continuity at the tile boundaries and representation of elevation values. 

Missing Data

Description

The 1m DEM Grids were derived using the Natural Neighbour interpolation using the ground and thinned ground classification classes. This method uses the closest triangles and applies weights to the proportionate areas from the grid cell centroid to interpolate the value. It uses known elevation data, it does not make any predictions regarding the surface and accurately depicts existing troughs and peaks in the data and supports irregular point spacing, which suits the nature LiDAR data. Grids were then translated to ESRI ASCII formats using custom ArcGIS and Feature Manipulation Engine (FME) macros.
