AI agencyAI agency for software, geodata and visualisation

AI and software that make the hidden visible.

We advise on AI and build web apps, maps and data visualisations – for SMEs, public administration and research. Verified, fast, data-minimal: in days, not months.

Making data visible. Four fields.

AService

AI consulting & delivery

From idea to a working prototype on your data – in one week. Then you know, with numbers, whether delivery is worth it.

AI opportunity analysis: prioritised use cases with effort and benefit
AI sprint: working prototype in five days, measured blind against a sample
Delivery: workflows, agents, integration with your systems
AI audit: independently re-measure existing AI workflows

Geodata & remote sensing

We read landscapes and places: LiDAR data become verified relief maps, open geodata become maps that answer a question. Candidate lists for heritage authorities and research only.

Terrain models from LiDAR point clouds, six verified relief views
AI screening of large areas with blind review and chain of evidence
WebGIS and map applications from open and official geodata
Web viewers for project partners, protected if needed

Geodata WebGIS

Visualisation of data and things

Data visualisation first: lines, maps and scroll stories you understand in seconds. And when it is about objects: 3D product images from our own pipeline.

Charts and lines with visible uncertainty
Maps and WebGIS from open geodata
Scrollytelling for reports and campaigns
3D product images and animations from CAD data

Tools we run ourselves.

Each Zeile answers an everyday question from open, official data – no account, no tracking. We build this for ourselves. You get the same care.

03How we work

AI makes us fast. Verification makes us reliable.

AI projects rarely fail for lack of speed, but for lack of trust in the results. So we build in both from the start.

Days, not months

Speed

Images, maps, documents: AI pre-sorts, people decide on a short, reasoned list.

Blind reviewlocation · expectation: hidden

#0417Straight edge, 180 mrejected · forest road, aerial 1968 ✓ cross-checked
#0418Round mound, 14 mopen · survey recommended
#0421Parallel furrowsrejected · skid trails ✓ cross-checked
#0426Rectangular hollowrejected · timber yard, map 1987 ✓ cross-checked
#0430Edge on slopeexplained · vineyard terrace, 19th c. ✓ cross-checked

Blind · reasoned · cross-checked

Verification

Every hit has to pass a blind review: the reviewer knows neither location nor expectation. Every rejection is reasoned and cross-checked. What remains is a short, reasoned list instead of a long, unchecked one.

Results, verifiable.
