The VLM engine as a graph

Source of truth · 8 measures × 8 perspectives. 8 weighted measures across 8 perspectives, deterministic and frozen by golden tests — the same formula for address, Grätzl and district. No chance, no AI.

language ⇄ weights. Gemini only translates — wishes into weights, facts into language. It never ranks and never invents a score; if it is down, the data-built text is there instantly.

8 axes from 14 signals. Every place as a profile of 8 axes, composed from 14 measured signals — personality, not a category, and never part of the score.

sun for every minute of the year. Sun position, a horizon from the official eaves heights of the neighbouring houses, terrain and tree crowns — computed for every window of an address, never guessed.

house, flat and street in 3D. The house from the official roof model, the flat from the floor plan, around it the real street: trees, lights, benches, crossings, stops — in the light of the computed sun.

facts → language. Measurements become language like a local Viennese friend’s — with a mandatory trade-off, never invented; computed once per Grätzl and perspective.

own vector tiles · MapLibre. Own tiles on our own domain, own style light and dark, 3D trees and night light — no Google Maps, no third-party server while you read.

official map + own overflight count. Road, rail and aircraft noise from the official environmental noise map, plus the own count of low-flying aircraft over 99 places. A measured drawback is never removed, only explained better.

summer heat modelled, climate measured. A summer-heat index per Grätzl from built form, green, trees, water and elevation — labelled as modelled, never as measured degrees. Plus the Hohe Warte climate series and today’s weather.

green roof, sun, room on top. From the official roof model: which roofs can carry a green roof, where a storey would fit and how much sun it would get — computed house by house, shown per district.

what the Azima report checks. Flood, heavy rain, torrents, earthquakes, radon, contaminated sites, geology, listed status and zoning from official tiles — read for every address, never guessed.

renders, previews, covers. From the own map, the build renders the pages’ 3D images, one preview image per page and the covers of the short films. A place’s character image is a real, freely licensed photo of the area, only restyled — the geometry stays.

open map library. Draws the map with WebGL from vector tiles — open source, no account with a map provider.

one tile file. All of Vienna in one file on our own domain; the browser reads just the tiles it needs via range requests.

the 3D stage. Renders house, flat and street — with WebGPU where the device supports it, otherwise WebGL2.

compressed all the way to the GPU. Plaster, parquet and foliage arrive as GPU-compressed textures — a fraction of the memory on a phone.

language model as translator. Translates wishes into weights and facts into language — with a fixed response schema, a small budget and a fallback to the data text.

computed astronomically. The sun’s path for every minute of the year with the NOAA method — accurate to the minute, also in winter.

Pages · Functions · R2. Pages, tiles and functions at the network edge, with no own server; counting happens there without cookies.

static pages. Every page is built as finished HTML — search engines and AI answers read real content.

fast return, partly offline. Keeps public files on the device — return visits load instantly, never with personal data.

climate and weather data. The official Hohe Warte climate series and today’s weather — openly licensed, credited as a source.

checkout for the report. Sells the Azima report as merchant of record with invoice and tax; loaded only when you click buy.

one palette, one sky. One colour palette for map, 3D stage and report and one computed sky per time of day — which is why the images look like the map they come from.
