Data infrastructure for construction, starting with land surveying

    Stop losing days to scattered records and scanned deeds.

    Every record a site needs: parcels, topography, flood panels, zoning, permits, utilities, plus the deeds and prior surveys buried in scanned PDFs, found, read, and cross-checked into one clean file. With a citation on every value, and every conflict flagged before your crew leaves the office.

    Used daily by surveying firms running real client jobs.

    The grind

    The data exists. Assembling and trusting it is the job.

    01

    Five portals for one site

    Parcel data here, flood panels there, zoning somewhere else, each with different datums and vintages. Every job starts with the same scavenger hunt across county and federal sources.

    02

    Deeds only a human can read

    Fifty-year-old scanned deeds, plats, and prior surveys in inconsistent formats. OCR chokes on them, so someone still reads and re-types every one by hand.

    03

    Conflicts caught on-site, not before

    A deed that disagrees with a neighboring survey, or boundary data that doesn't reconcile. Too often nobody catches it until a crew is already standing on the parcel.

    What you get

    The finished file. Not a pile of links.

    One file, not twelve downloads

    Describe the site or parcel. Get back a single, ready-to-use table with every layer you asked for already joined and aligned.

    Deeds and plats, read for you

    Vision-LLMs read scanned, decades-old deeds and prior surveys accurately, with no OCR guesswork on documents that were never designed to be machine-read.

    Conflicts flagged automatically

    A deed that disagrees with a neighboring survey, or a boundary that doesn't reconcile, surfaced before your crew leaves the office, not after.

    A citation on every value

    Each field traces back to its authoritative source and pull date. Defensible for clients, reviewers, and the record.

    Aligned to a common frame

    Projections reconciled, units normalized, timestamps matched. The cleanup step is done before the file reaches you.

    The sources you already trust

    County assessor and GIS, USGS, FEMA, municipal zoning and permits, county recorders, utility and ROW records, composed, not scraped from somewhere sketchy.

    How it works

    From request to deliverable. Three steps.

    Step 01
    1

    Tell us the site

    An address, a parcel number, a county boundary, and the layers and documents you need for this job.

    Step 02
    2

    Mobus reads, composes, and checks it

    It locates each GIS source, reads scanned deeds and prior surveys with vision-LLMs, reconciles projections and units, and flags where sources disagree.

    Step 03
    3

    You get the file + provenance

    A clean file with a source citation behind every value and a conflict report where anything didn't reconcile, in the format your workflow expects.

    Why trust it

    Built on an engine already used in production.

    Open-source roots

    The data engine behind Mobus started as an open-source project researchers use to search across dozens of public data platforms.

    In production, not a prototype

    Surveying firms run Mobus on live client jobs today. This is the same engine, built first for land surveying and expanding along the same construction data problem.

    Provenance by default

    Nothing is a black box. Every value carries its source and pull date, so the work holds up when someone asks how you got it.
