Vector data is points, lines, and polygons. How the two GIS data models differ, their formats, and how to combine them. 6 Mins Read 3 Oct 2026 What is Parcel Data? Parcel Numbers, Boundaries, Sources Parcel data records every piece of land: its boundary, parcel number, owner, land use, and assessed value. Where it comes from and how to use it. 5 Mins Read 29 Sep 2026 Data Center Site Selection: Criteria, Data Layers, Process Data center site selection is the process of finding land where a facility of 50 to 1,000 megawatts can be powered, connected, cooled, permitted, and kept out of harm’s way. It screens candidate parcels against grid capacity, fiber routes, water availability, natural hazards, zoning, and latency to users, then ranks the survivors on cost and […] Sign up for our newsletter Be the first to know about releases and industry news.
