Quantified linear distortion.
LDP Design provides you with a map-centric design environment where you can interactively change map projection parameters and visualize distortion in parts per million (= mm per km).
Custom coordinate grid definition.
Because an LDP is a custom coordinate system, LDP Design allows you to define coordinate values everywhere in the design area that are distinct from other coordinate system values for that area (such as State Plane or UTM). This helps reduce the risk of confusing LDPs with other systems.
LDP Design generates coordinate systems that are used directly to represent conditions “at ground” for a variety of geospatial products and services. This includes the direct use of high-accuracy survey deliverables in GIS (e.g., boundary plats, engineering plans, as-built surveys) and installations where GIS is directly supporting infrastructure construction and maintenance (roads, pipelines, canals, etc.).
