Down to your next move.
MEET RANCH MAPPER
One field.
Three useful steps.
Start with ground you know.
Come back with a record of the work.
Actual app demo · Public aerial imagery + elevation · Relief exaggerated · Not a survey
From an outline to acres.
Find your ground, draw a field, and see the acreage. Already have boundaries? Bring in your KML, KMZ, Shapefile, or GeoJSON.
- Explore real 3D terrain
- Label wells, gates, and places that matter
- Export your boundaries anytime
Map acreage from your outline. Not a legal survey.
Pick a place to check.
Explore slope and modeled low spots, then check the area forecast in Weather before heading out.
- Read the shape of your field in 3D
- View forecast wind, rain, and temperature
- Choose a place to investigate on the ground
Terrain layers are scouting aids. Weather is a separate area forecast; the 3D animation illustrates it.
Keep the work with the field.
Open Work to enter fertilizer use, spray records, yield estimates, and harvest actuals. Add a ranch and field there if you need to log first and map later.
- Use your crops, labels, and units
- Keep recorded application acres when you map later
- Export records and keep a device backup
Check each fertilizer record’s sync status. Spray records stay on the device; include them and other device-only details in your backup.
Explore all terrain tools 9 tools, with their limits
💧 Ponding & drainage Beta
Find modeled depressions and possible drainage paths from the terrain. Blue shows filled basins; cyan shows modeled flow paths. Use them to choose low spots to inspect.
Won't tell you. Terrain shape only. The acre-feet figure is a brim-full worst case — every bowl filled to the lip — a modeled storage volume, not observed flooding or a drainage design. 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
Explore relative cold-air pooling from terrain shape: blue for lower pockets and orange for higher-ranked thermal belts. These are places to check, not measured temperatures or predicted frost.
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
Compare terrain-based drainage tendencies within a field. Red marks relatively shedding areas, blue marks collecting areas, and cyan traces modeled runoff paths. The map does not measure soil moisture or simulate an irrigation set.
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
See which direction each slope faces. Use the orientation as one clue when checking differences in exposure across the field.
Won't tell you. Direction off the terrain surface, nothing else — no sun, no season, no soil, no canopy.
⛰️ Earthworks (cut/fill) Beta
Explore a balanced cut-and-fill estimate in cubic yards from the loaded elevation 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, higher and lower NDVI acreage. 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.
Reading the map: Detail depends on the source and the loaded terrain window. Nearby-detail settings control loading effort. Vertical scale changes the display: 1× shows true proportions; higher values exaggerate relief. Read the numeric slope and acreage values rather than judging them from the 3D view.

A FEW GOOD QUESTIONS
Good tools.
Clear limits.
Public data. Your records.
No mystery in between.
How good is that acreage, really?
It is the flat, top-down area of the boundary you draw. It does not include extra surface area from hills, and its accuracy depends on your outline. It is not a legal survey or a verified deed or FSA acreage. Check the relevant official records before using it for a transaction or filing.
Where does the 3D terrain come from?
Public USGS 3DEP elevation with USDA/NAIP aerial imagery. Source coverage and resolution vary by location; the app can fall back to coarser public elevation when finer data is unavailable. Check the map source and detail labels. Aerial imagery is from its capture date, not live; a date may be unavailable. Vertical scale above 1× exaggerates relief for viewing.
Does it work without a signal?
Prepare before leaving service: open the app, use the offline download controls to save the area and layers you need, and run its readiness check. Reopen that saved area without a connection to confirm it on your device. Downloaded terrain supports drawing, measuring, and markers; device records can also be used offline. Search, fresh weather, and cloud sync need a connection. Browser storage can be cleared, so keep a separate backup of your records.
Who owns my data, and can I get it out?
You do. Export field boundaries and supported records as CSV or GeoJSON, and use the FieldForge backup for device records. Saved map areas use separate offline map downloads or packs. Private scans and other device assets may need their own copies; check the backup contents rather than assuming one file contains everything. Exports and backups remain available without paid access.
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 with Google or email to sync ranch names, field boundaries and basic details, markers, and yield records. Sync is free during beta and planned for Pro when paid plans launch. Fertilizer records show whether they are synced or still waiting for cloud. Spray records, access pins, legal descriptions, bed layouts, your library, and private scans remain on this device. Check the in-app sync status and keep a backup for device-only data.
Are the terrain tools telling me what to do?
Terrain tools use the shape of the land to help you choose where to investigate. They do not measure soil conditions, crop health, or actual flooding. Some colors rank locations only within the current field. Weather is a separate, on-demand area forecast, and its 3D animation is illustrative. Neither provides an agronomic, engineering, or compliance decision.
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?
Start as a guest with device records, or sign in to sync supported records. The optional AI assistant uses your own Anthropic key and sends the conversation and crop list directly to Anthropic after you review each request. Field records are not attached automatically, but any details you type into the conversation are included. Weather uses a rounded location; crop detection sends field coordinates to USDA. Review each tool’s sharing notice before using it.
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.
