Know the groundbefore you pour concrete.
For developers, real-estate underwriters, infrastructure planners and property insurers: compress terrain, hydrology and ground-motion risk into one buildability score — measured from a global DEM, live Sentinel-2 imagery and the seismic catalogue.
What the API does for construction.
A five-point DEM stencil returns a true local gradient and relief, so earthworks exposure is quantified before a surveyor is booked.
NDWI and NDMI expose standing water, seasonal flooding and persistently wet substrate that wrecks excavation and drainage budgets.
NDBI shows how much of the site is already built or hard-standing, which changes clearance cost and utility proximity assumptions.
Five years of catalogued ground motion within 200 km feeds a georisk sub-score that underwriters can defend.
Coordinate to decision, step by step.
Every construction request runs through the same five stages. Nothing is cached from a neighbouring tile and nothing is invented — if a pixel is unusable, the response says so.

- Same coordinate → same answer
No random seeds. No hidden drift. If you got a 74 last Tuesday, you'll get a 74 next Tuesday — unless the ground itself has changed. That is what makes the score defensible in an underwriting memo, a planning submission, or a board pack.
Three fields in. That is the whole input.
No shapefiles. No polygons. No uploads. No GIS stack to maintain.
latnumberLatitude in decimal degrees. Use the plot centroid, a proposed foundation point, or an interval along a corridor.
lngnumberLongitude in decimal degrees.
mode"construction"Construction mode weights terrain and georisk most heavily and treats dense vegetation as clearance cost rather than a positive.

Every construction score is built on the same public Earth-observation feeds that power commercial GIS stacks sold for tens of lakhs to crores per annum. We expose them directly through one simple HTTP call.
10–20 m multispectral surface reflectance from ESA's Copernicus Sentinel-2 constellation, served as cloud-optimised GeoTIFFs via the AWS Earth Search STAC catalogue. Every request samples the actual pixel at your coordinate for red, green, NIR and SWIR bands.
GLO-90 digital elevation model from the Copernicus DEM programme, sampled through a five-point stencil so slope and local relief are measured, not assumed. The centre point plus four surrounding points gives a true local gradient.
Every sampled pixel is checked against the Sentinel-2 SCL. Cloud, cloud shadow, thin cirrus, saturated and no-data pixels are rejected outright — not smoothed over — so the score only sees ground truth.
Open-Meteo historical climate reanalysis provides temperature, precipitation and humidity baselines at the coordinate. The 5-year seismic catalogue supplies catalogued ground-motion frequency and peak magnitude within 200 km.
No random seeds. No hidden drift. If you got a 74 last Tuesday, you'll get a 74 next Tuesday — unless the ground itself has changed. That's what makes the score defensible in an underwriting memo, a planning submission, or a board pack.
What you get back.
A plain-English report anyone can read. No remote-sensing degree, no GIS software, no manual report.
One simple number that tells you how buildable this site is.
Slope, water saturation, and ground-motion risk measured for the exact point.
What is already on the ground — greenfield vs built-up, wet areas, and usable surface.
A simple label like Stable, Caution, or High Risk, plus a recommended action.
The result comes as clean JSON that any software can read.
The parameters behind the score.
Every response is one score plus the measured parameters that produced it. Which parameters come back depends on the vertical you query.
Gradient measured at the exact coordinate.
Local elevation variability around the point.
Standing water and retained ground moisture.
Whether the site is bare soil, vegetated greenfield or already built-up.
Recorded events and maximum magnitude near the site.
Rainfall intensity and temperature extremes.
What those outputs do in real life.
Push thousands of candidate coordinates through the API and rank them by stability before a single survey team is dispatched.
Attach a reproducible site-risk score with component breakdown to bids, proposals and lender submissions.
Slope and moisture together show where roads, cranes and heavy equipment can realistically operate, and in which season.
Re-score built and in-progress sites quarterly to catch erosion, waterlogging or encroachment while remediation is still cheap.
Pick a coordinate. See the real output.
These are live calls to the production construction engine — real Sentinel-2 imagery, real elevation, real climate and seismic records. Nothing here is mocked.
Coastal urban expansion zone
Steeper ground means more cut, fill and platform cost
How rugged the surrounding ground is
Height above sea level at the point
Standing water — dewatering and flood exposure
Retained moisture that weakens bearing capacity
Greenfield vegetation vs bare, erodible soil
How developed the surface already is
Recorded seismic events nearby
Strongest recent nearby quake
Fused live from Sentinel-2 L2A optical imagery, Copernicus GLO-90 elevation, NASA POWER climate reanalysis and the USGS seismic catalogue — returned in a single JSON response, typically in about a second.
How this was done before — and what changes.
Every row is a task construction teams already do today. The left column is the traditional method. The right column is the same task with one API call.
Ten bands. One axis. Zero ambiguity.
The 0–100 axis is partitioned into ten calibrated bands, each mapped to a defensible construction decision — identical across every coordinate on Earth.
The operational workflows Rootfifteen replaces.
Pre-screening development sites
Reject obvious georisk before expensive surveys and focus engineering budgets on viable parcels.
Infrastructure corridor planning
Compare route options at regular intervals and reroute early around unstable ground.
Renewables portfolio siting
Rank hundreds of solar, wind, transmission, and warehousing sites on the same axis overnight.
Property insurance re-pricing
Move beyond ZIP-code averages and price single-asset ground risk on a precise 0–100 signal.
Drop the API into the systems that already run construction decisions.
Rootfifteen is one HTTP endpoint. That means it fits inside any software that already touches construction workflows — no new dashboard, no new map stack, no internal GIS team required.
Reject high-risk parcels before survey spend and rank candidate sites on a single objective score.
Attach a buildability score to every project record and gate engineering scope before budget approval.
Score waypoints along roads, rail, pipelines, and transmission lines and reroute early around unstable ground.
Rank hundreds of candidate sites for slope, access, and flood risk before a single site visit.
Replace ZIP-code averages with a single-asset ground-risk score backed by DEM and seismic data.
Add a reproducible, component-level site-risk annex to bids, memos, and lender submissions.
Every construction call returns a 0–100 score, a calibrated band, a machine-readable classification, and the component sub-scores that explain it. Wire it into your underwriting engine, your site-screening workflow, or your command map exactly like any other REST API.
