💧 Ponding & drainage Beta
Blue where water would sit after a rain or a heavy set, with depth and acre-feet; cyan traces the channels it drains along. Where you'll get standing water and drowned crop.
Won't tell you. Terrain shape only. The acre-feet figure is a brim-full worst case — every bowl filled to the lip — a ceiling for sizing drainage, not the rain you're going to get. It ignores soil soak-in, actual rainfall, and existing tile or drains, and reads a coarse grid, so narrow swales get missed.
❄️ Frost map Beta
Blue where cold air settles on a calm clear night — the pockets that frost first and thaw last — and orange for the mid-slope thermal belts that stay a touch warmer.
Won't tell you. No temperature, no wind, no date, no forecast. Real wind mixes the air and can erase pooling entirely. Colors are ranked within this one field, so even fairly uniform ground still shows blue and orange. Relative risk to go scout, nothing more.
☀️ Sun hours Beta
Hours of direct sun on each part of a field today, given the hills and ridges around it. Yellow sunniest, blue most shaded — good for the corner that's chronically cold and slow to dry.
Won't tell you. Terrain shadows only. No clouds, no fog, no trees, no buildings. Times are local solar time and colors are scaled to this one field, so “yellow” only means sunniest here. Read the hours.
🚿 Irrigation zones Beta
How the lay of the land pushes water around if you run one uniform set across the whole field: red sheds and tends dry, blue collects and water-logs, cyan lines are where water runs off and leaves.
Won't tell you. This is a terrain-layout aid, not an irrigation recommendation. No evapotranspiration, no soil type or infiltration rate, no weather, no crop stage. Sandy versus clay can flip what a zone means. Zones rank within one field and are never an absolute rate. Size and schedule real irrigation with your agronomist, your soil and ET data, and your meter.
🚧 Setback / buffer acreage Beta
Pick 25, 50, 100 feet or your own number and it draws the buffer in from every edge, leaves the plantable core green, and gives you the acres of each plus the percent you lose.
Won't tell you. You enter the distance — the tool does not decide the legal buffer. That comes off the chemical label, your county ag commissioner, and what's next door. It measures flat distance from the boundary you drew, ignores internal features like wells and ditches, and flags on screen when a very small setback on a large field gets approximate.
📐 Slope (% grade) Beta
Percent grade across the field — green gentle, red about 15% and steeper — with the average, the steepest, and how much of the field sits over a working grade.
Won't tell you. These are absolute grades on a fixed scale, but still a field-scale read off a coarse public grid. It won't find a two-foot berm, and it is not an engineering design or a machine-safety determination.
🧭 Aspect Beta
Which way each piece of ground faces, so you can see the south-facing slopes that dry and warm first and the north faces that stay cold and wet.
Won't tell you. Direction off the terrain surface, nothing else — no sun, no season, no soil, no canopy.
⛰️ Earthworks (cut/fill) Beta
A balanced cut-and-fill estimate in cubic yards for leveling a field, read off the lidar surface.
Won't tell you. A terrain-model estimate, not an engineering design. No shrink or swell, no haul modeling, and a balanced plane is not a designed grade. Never a pay quantity.
✈️ Change detection Beta
Pin two single-band drone scans of the same field — a DSM pair or an NDVI pair — and get a per-cell change overlay: cut and fill in cubic yards from elevation, improved and declined acreage from NDVI. Ranch Mapper also displays imported GeoTIFF scans (RGB, NDVI, elevation) draped on the 3D terrain.
Won't tell you. The tool compares maps; it does not make them, align them, or calibrate them. Photogrammetry surfaces include the canopy, so a cut/fill figure stacks both flights' errors. NDVI here is relative, not calibrated — where to walk first, not a diagnosis and not a prescription.
Also on screen: a Neighbor detail control — Cached only, Balanced, Maximum 3×3 — decides how hard the app works to keep the ground around you in high detail while you travel. It changes loading effort, not the resolution of the underlying data; phones and constrained devices stay on cached tiles regardless. And a vertical-scale slider exaggerates relief on purpose so gentle ground reads — what you see is not true steepness.

A FEW GOOD QUESTIONS
Good tools.
Clear limits.
Public data. Your records.
No mystery in between.
How good is that acreage, really?
It's the standard map acre: the flat, top-down area of the boundary you drew, the same acre the FSA, deeds, and landlords work in. It uses no elevation, so on hilly ground the true surface is slightly larger. It is not a legal survey — verify against a recorded survey before you buy, sell, split, or sign.
Where does the 3D terrain come from?
Public USGS 3DEP 1-meter lidar for elevation, USDA/NAIP aerial imagery draped over it. High-detail ground keeps loading around wherever you're looking, and a Neighbor detail control lets you choose how hard it works at that. Where 3DEP is missing or malformed for your area, it falls back to a coarser public elevation source rather than inventing terrain. The vertical-scale slider exaggerates relief on purpose so gentle ground reads.
Does it work without a signal?
Yes, on ground you've already loaded. Install it as an app, load your fields while you have service, and you can draw, measure, mark, and keep records offline. Search is online only, the cache is the map, and sync waits for signal.
Who owns my data, and can I get it out?
You do. CSV and GeoJSON export plus a full bundle backup (beta) are free and stay free. If you decide this isn't for you, your boundaries and your records leave with you.
More questions: sync, pricing, privacy & support
What does it cost, and what's the catch?
Free while we're in beta — the full terrain toolkit, nothing locked, no credit card. Monthly plans are coming: Pro is $19/month for one person, and Operation is $49/month for five people including the owner. Pro includes unlimited fields and ranches, cross-device sync, and drone overlays. Operation adds a shared workspace with editor and viewer access. Checkout is not open yet. Exports, backups, and access to your saved local records stay available when paid plans launch.
Do my maps sync across devices?
Sign in free with Google or email and your fields, markers, yield estimates, and ranches sync across phone, tablet, and desktop. Sync is free while we're in beta and will be part of Pro when paid plans launch. Spray records are not part of cloud sync yet — they live on the device and travel in your bundle backup.
Are the terrain tools telling me what to do?
No. They read the shape of the land and nothing else — no soil, no weather, no crop, no sensor — and most of them rank colors within one field, so a color only means “compared to the rest of this ground.” They tell you where to go look. They are not agronomic determinations, engineering designs, or compliance verdicts.
What is the plant layer actually showing me?
Representations generated from the bed configuration you entered — bed width, seed lines, plant spacing — drawn on the boundary you outlined. No camera and no sensor has seen those plants. Sizes are modeled mature diameters and get gently boosted with distance so rows stay readable at altitude. It is not counting, scouting, or sensing anything.
What operations and crops does it fit?
Any US operation — row crop, ranch and grazing, orchard, or produce. One-click starter sets pick the right units and labels, Simple mode hides what you don't use, and the crop, variety, pack, and unit library is fully editable.
How do you handle my data and privacy?
Your maps stay tied to your account and are never sold. The optional AI assistant runs on your own Anthropic key and keeps everything on your device — only your crop list and what you type are ever sent, never your fields, acreage, or yields.
How do I get help?
Send a note from the support form below — we read every message and reply to the email you give us. There's in-app help in the Ranch Mapper too, and the field guides walk through the common jobs step by step.
What should I know before relying on a map?
Acreage is calculated from your outline, not a survey. Terrain tools use public elevation, with detail that varies by location. They do not account for soil, weather, crop stage, or equipment. Aerial imagery is from its flight date, not live. Spray intervals and setback distances come from values you enter; they are not compliance determinations. Use these tools to decide where to investigate, with professional advice for agronomic, legal, and engineering decisions.
