NUAR and the CDM Liability: What Every Asset Owner Needs to Know
The National Underground Asset Register is now live. For every organisation that owns, manages, or works near underground utilities, NUAR changes the legal and data landscape materially. This article explains what NUAR requires, why the CDM liability is the key risk, and how to assess your readiness.
UK GEMINI 2.3: Why Most Implementations Fail at the Data Model Layer
UK GEMINI 2.3 is mandatory for government geographic data across Defra, DLUHC, and central government bodies — yet most implementations are superficial, covering 20–30 elements and calling it compliance. This article explains where GEMINI implementations fail, and what real compliance looks like.
CDM, LDM, PDM: The Three-Layer Architecture That Makes Geospatial Data Last
Most GIS projects fail not because of the wrong tool, but because the data structure was never formally designed. CDM, LDM, and PDM are the three layers that turn a collection of spatial files into a coherent, maintainable data architecture — and skipping any one of them is the most common and expensive mistake in geospatial programmes.
