Snapshot

Client: GeoSoft — a new Slovak SaaS for land surveyors (geodeti) in Slovakia and Czechia.

Engagement: Take a professional workflow that has lived in Windows desktop software since the 1990s and move it — whole — into the browser: CAD drawing, geodetic computation, cadastral outputs and data conversions, delivered as a subscription instead of per-PC licences.

What we shipped: A multi-tenant web application with a React CAD editor up front and a GeoDjango + PostGIS computation engine behind it. Every surveying firm gets an isolated workspace on its own subdomain; registration takes under a minute, with no card and no installation.

The product at a glance

Drawing tools	11 — point, line, polygon, circle, arc, rectangle, spline, text, dimension, symbol, measure
Geodetic methods	polar, orthogonal, intersections, free station (least squares), Helmert transformation, 3D rajón, levelling network adjustment
Coordinate systems	S-JTSK, WGS84, UTM
Data formats	DXF, SHP, VGI in · DXF, SHP, VFK, PDF out
Tenancy	isolated workspace per firm, on its own subdomain

What we actually built

1. A CAD editor that lives in a tab

An SVG-based canvas with pan/zoom, layer management, undo/redo and eleven drawing tools. Around it, the details that make CAD usable for real work: a snap engine (endpoints, midpoints, intersections, perpendicular feet), vertex editing with drag handles, and a command line modelled on the legacy desktop software surveyors already know — twenty years of keyboard muscle memory keeps working, including UNDO/REDO.

2. A real computation core, not a drawing toy

Geodetic software stands or falls on the maths. The backend engine covers the polar and orthogonal methods, intersections, free-station setup solved as a full least-squares adjustment, Helmert transformation, 3D polar survey (rajón) and 1D levelling network adjustment — with coordinates handled natively in S-JTSK, WGS84 and UTM, and areas reported in m², ares and hectares.

3. Cadastre-native outputs

The deliverables a surveying office actually invoices: geometric plans (GPL) including VFK export for the cadastre, parcel management with Czech/Slovak parcel-number handling (1234/5), land-consolidation workflows (ROEP/PPÚ) and print layouts exported to PDF.

4. Conversions as daily bread

A surveyor’s day is format juggling, so import/export is a first-class feature, not an afterthought: DXF, SHP and VGI in; DXF, SHP and VFK out. The conversion pipeline preserves layers and attributes instead of flattening the drawing.

5. Multi-tenant SaaS underneath

One codebase, many firms: multi-tenant architecture on PostGIS gives each company an isolated workspace with its own data and its own subdomain. Full functionality on every plan, unlimited projects, no long-term contract — and priority support that includes help migrating from the legacy desktop tools.

What we’re holding back

The symbol-library internals, the VFK pipeline roadmap, the real-time collaboration plans and what the e2e test suite looks like for a CAD canvas. Happy to walk through it on a call.
