A glittering penthouse in Manhattan might be “owned” by 1372 Fifth Avenue Holdings LLC , which is managed by a law firm, which acts as agent for a trust, whose beneficiary is a numbered company in Luxembourg. It takes a forensic accountant months to untangle. A Cadmapper can do it in an afternoon—because they’ve already built the relational database that connects LLC registration numbers to beneficial owners scraped from leaked corporate registries.

For areas where building height information is missing, Cadmapper allows you to assign a default height, which might not be accurate.

Cadmapper handles terrain well, producing topographic meshes and contour lines from satellite elevation data, crucial for hilly or sloped sites.

The precision of building heights and road mapping depends on the quality of OpenStreetMap entries.

The cadastre is never neutral. Neither are those who draw it.

One Cadmapper I spoke with (she asked to remain anonymous, for fear of doxxing by real estate interests) described the process as “archaeology, but the artifacts are trying to charge you rent.”

Cadmapper's strength lies in its simplicity and the richness of its data exports.
