01 / PIPELINE

From a point on the map to a build-ready file.

Four stages, fully automated. The same authoritative data the state uses — processed in your browser, in seconds.

01

Locate

Pick parcels on a statewide map, search a tax ID or address, or upload a survey.

02

Elevate

Pull USGS 3DEP LiDAR for the exact footprint and build a 1 m elevation surface.

03

Analyze

Compute slope (Horn 1981) and overlay DEC-regulated wetlands — instantly re-thresholdable.

04

Deliver

Export a PDF report or a georeferenced CAD file with contours on labeled layers.

02 / CAPABILITIES

Site intelligence, decoded.

Everything a planner, surveyor, or developer needs to understand a piece of ground before the first stake goes in.

CAP.01

Statewide, to the meter

Every county in New York, analyzed on 1 m LiDAR. UTM zones selected automatically — correct from Buffalo to Montauk.

CAP.02

Any slope threshold, live

Move a slider and the steep-slope share and acreage recompute instantly in your browser — no waiting on a re-run.

CAP.03

Regulated wetlands, included

DEC-regulated, Army Corps / NWI, and informational wetlands measured to the acre, right inside the parcel.

CAP.04

Build-ready deliverables

Hand engineering a georeferenced DXF/DWG with steep-slope contours and wetland polygons — or a clean PDF for the file.

CAP.05

Draw any site

Not just parcels — outline a development footprint across multiple lots and analyze it as one combined area.

CAP.06

Seconds, not weeks

What used to mean ordering survey data and waiting now takes one click against authoritative public GIS.

03 / COVERAGE

By the numbers.

AUTHORITATIVE PUBLIC DATA

Parcel boundaries are available for the New York counties that publish them (38 and growing); elevation and wetlands cover the entire state. Results are planning-level estimates from public GIS — not a survey. See your county →
