Proved, not asserted.
Others give you a number. Situs brings the chain of reasoning: measurement, source, data vintage, scoring rule and confidence — for every single attribute.
Proved, not asserted
Every attribute carries its measurement, source, recording date and the scoring rule applied. The full chain of reasoning is part of the result — optionally as a print-ready appendix in appraisal format.
Computed the same way, everywhere
City centre or village: the same measurement specification, the same rules. Two calls with the same model version and data vintages return identical results — reproducible, even years later.
Honest about data gaps
Every rating carries a per-attribute confidence. If a source is unavailable, it is disclosed and lowers confidence — never silently counted as zero. Anything that cannot be verified is listed explicitly under “limits of the statement”.
Verdict and measurement profile
The overall residential-location grade condenses to one step; alongside it, the location code shows what it is made of. Contrasts remain visible instead of vanishing into an average.
Anchored in standards
Where recognised standards exist, scoring rules are anchored to them — e.g. WHO recommendations and DIN 18005 for noise, or the official flood hazard maps.
Drop-in integration
One call with coordinates and federal state — back comes a structured, versioned result object. For valuation software, portals, risk workflows, or directly as an appendix in the appraisal.
What you get.
A structured JSON object — from the verdict down to every line of the reasoning chain.
- 01
Residential-location grade
very good · good · medium · simple residential location, with a 0–100 score.
- 02
Location code
Compact code, e.g. DE/SN/K1/W-A2B — place, place-size class and three sub-grades at a glance.
- 03
Three facet scores
Location & accessibility · Market environment & social · Living environment & housing quality.
- 04
Strengths & weaknesses
In plain text, derived from the measurements — including evidenced positive findings (“no flood exposure”).
- 05
Reasoning chain
Every attribute with measurement, source, data vintage, points and confidence.
- 06
Confidence & versions
Overall confidence, per-attribute confidence, model and data-vintage identifiers.
How it works.
Four steps from location to reasoned verdict.
- ①
Measure
Roughly 30 attributes are recorded at the location — traffic noise, public transport frequency, walking time to the nearest supermarket, proximity to schools and daycare, greenness from satellite data, flood exposure, air quality, building age and style of the neighbourhood, local rent level. Every measurement carries its source and recording date.
- ②
Score
Each measurement is translated into points via a documented, disclosed scoring rule. Where recognised standards exist, the rules are anchored to them — e.g. WHO and DIN 18005 for noise, or official flood hazard maps.
- ③
Aggregate
The scored attributes are combined into three facets — weighted by confidence: an uncertain value pulls less than a certain one.
- ④
Judge
The overall grade emerges from the facets. In addition, hard rules apply to defects that cannot be professionally offset: a park next door does not neutralise a flood risk. The result states this derivation.
Residential-location classification: Simple residential location — score 79/100. A location score of 79/100 would correspond to a good residential location. Substantial traffic noise (Lden 71 dB, road/rail) limits the classification to a simple residential location.
So the grade never deviates from the score without explanation — the rating justifies itself.
Why a verdict alone is not enough.
A single value hides contrasts: a village can be poorly accessible yet exceptionally quiet and green. The overall grade averages this — the location code shows both. Everything before the hyphen is fact (where), everything after is rating (how good).
Two properties with the same code have the same measured location properties — comparable across cities and portfolios.

Exclusively official and open data.
Situs works exclusively with official and open data holdings. No personal data is processed; the residents of a neighbourhood are not qualified.
Available today: Saxony and North Rhine-Westphalia.
Full coverage, every attribute data-driven. The computation core is state-agnostic; each further federal state is added as a defined onboarding package.

What Situs deliberately does not do.
Does not replace a site visit
Situs provides the auditable, everywhere-comparable basis that the expert weighs and takes responsibility for.
Rates locations, not people
No personal data, no qualification of residents.
Hides no limits
Whatever cannot be verified automatically (e.g. contaminated-sites registers) is listed as an open check point instead of quietly left out.
Embeddable anywhere. Deterministic. Versioned.
REST API: coordinates + federal state in, structured JSON out — grade, score, location code, facets, reasoning chain, confidences, version identifiers. Same input, same model version, same result.
