sitedia takes one address and draws a full set of site-analysis diagrams for it. Pick a site, pick a radius, and you get buildings, land use, year built, high-rise and low-rise, green space and water, roads, transit, city block grain, density and terrain — each in a matching circular or rectangular frame, ready to download as SVG, PNG, DXF or 3D (GLB, 3DM, DAE).
Anyone who has put together a design report has done this: screenshot a map, drop it into Illustrator, trace the buildings one by one, color them by use. An hour or two per drawing, and you start over when the site moves. The time goes into drawing, not into thinking.
But almost everything in those drawings is public data. Building footprints and heights, the year a building went up, what the lot is used for, where the parks and subway entrances are — all of it is already published. What was missing was a way to put it on a report page at a fixed scale, in a consistent frame, with a legend that matches.
That is the whole product. sitedia does not interpret your site for you. It draws the base material accurately and fast, so the analysis is yours to write.
It is not a zoning check and not a feasibility study. There are no zoning district boundaries, no FAR calculations, no setback envelopes in the US version — those need jurisdiction-specific datasets and legal review, and getting them subtly wrong is worse than not showing them at all.
It is also not a survey. Everything here comes from open datasets with their own vintages and error margins. Use it for analysis and communication, not for anything that needs a stamped drawing.
New York City — all five boroughs, plus whatever falls inside the bounding box (parts of the New Jersey waterfront come along; those buildings render but have no year-built data, since MapPLUTO covers NYC only). More cities are coming; the pipeline is built per city, so each one is a data build rather than a rewrite.
Every panel carries its own source note in the exported file, so a drawing that leaves your desk still says where it came from.
sitedia is built and run by one person — an urban designer who got tired of tracing buildings. It started as a Korean tool and grew a US edition because the problem is the same everywhere. If a panel looks wrong, or a dataset you rely on is missing, the feedback button on the main page reaches me directly.
