ALP is Arx-Prima's cadastral GIS platform for development teams — scan French parcel data end-to-end, score infill and division potential, model PLU constraints and feasibility, and reach landowners directly.
Every feature in ALP is designed to replace manual cadastre lookups with instant, defensible data on unbuilt land opportunities.
ALP connects directly to the official IGN Parcellaire Express and Etalab archives across all French municipalities, streaming parcel boundaries and plot geometry with GPU-accelerated rendering.
ALP evaluates unbuilt surface area, footprint ratios, garden-division potential, and urban infill gaps to surface high-yield opportunities before they reach the open market.
Zoning perimeters, height limits, and buildability constraints sync directly from French national planning repositories — no manual municipal document searches required.
Every parcel is screened for flood risk (PPRi), clay shrink-swell subsidence (Argiles RGA), known cavities, and heritage-site (ABF) constraints.
ALP turns geospatial data into a full developer balance sheet — projected floor area, sales revenue, construction cost, and acquisition ceiling — exportable as a one-click PDF prospectus.
Identify the registered owner of a parcel and launch a personalized outreach campaign directly from your dashboard, with certified postal tracking. Requires bringing your own postal dispatch API key.
Every parcel is checked against Géorisques' BASIAS historical industrial-site register and ICPE classified-facility database, with distance and Seveso status flagged automatically.
ALP surfaces the closest recorded ADEME energy performance diagnostic (DPE) and greenhouse-gas rating for existing structures near a parcel.
When a parcel's registered owner is a company or public body, ALP resolves its SIREN, legal form, and head-office address via INSEE, and checks BODACC for active insolvency proceedings.
Filter by grouped/consolidated surface, built footprint, and land nature, plus — where enrichment data exists — owner type and financial standing, alongside density and zoning filters.
ALP queries these registries directly. Every figure a developer sees traces back to one of these official sources.
Official parcel boundaries, geometry, and cadastral section/numero references for every French commune.
Live PLU zoning perimeters, height limits, and buildability rules synced from the national planning register.
Real recorded property transactions — sale date, price, surface, and asset type — for market benchmarking.
Flood risk (PPRi), clay shrink-swell (RGA), heritage easements (ABF), former industrial sites (BASIAS), and classified facilities (ICPE).
