Satellite Map That Shows Property Lines (Free, 2026)

The fastest free way to see your property lines on a satellite map is your county's GIS portal. Search your address, and the county draws your parcel boundary over aerial imagery using data from the tax assessor. It takes about a minute and costs nothing.

Google Maps will not reliably do this. Here is why, what the alternatives are, and how accurate any of it actually is.

Why satellite imagery alone does not show property lines

This is the confusion behind the whole question, and clearing it up makes everything else make sense.

A satellite image is a photograph. It shows roofs, trees, driveways and fences. It contains no information about where your legal boundary sits, because a boundary is not a physical thing a camera can see.

Property lines are a separate data layer, drawn on top of the photograph. That layer comes from county parcel records, maintained by the tax assessor. When a map appears to show your property lines, what you are looking at is two datasets stacked: imagery from one source, parcel geometry from another.

That is why some tools show boundaries and others do not, why the same address can look different on two sites, and why the lines are sometimes visibly wrong. You are not looking at a measurement. You are looking at one agency's drawing, laid over another agency's photograph.

Satellite imagery versus aerial photography

Worth knowing, because it determines how much detail you can get.

Satellite imagery is captured from space, usually 400 to 700 km up. Free public sources land around 50 cm to 1 m per pixel. Commercial providers push down to 30 cm.

Aerial photography is shot from planes or drones a few hundred metres up. Resolution reaches 7 to 15 cm per pixel, sharp enough to read roof shingles.

Confusingly, what Google labels "Satellite" in urban areas is often aerial photography, which is why its detail beats what the word implies. In most US cities Google runs around 15 to 30 cm.

For orientation, research and casual planning, free sources are more than enough. The upgrade only becomes necessary for roof inspection, listing photography and construction documentation.

Free ways to see your property from above

1. Your county GIS or assessor portal

Start here. Nearly every US county runs a public GIS site where you search an address and see your parcel drawn over aerial imagery. The data comes straight from the tax assessor, and the imagery is often higher resolution than Google's because the county contracts its own flyovers, frequently annually.

A typical county portal shows parcel boundaries, lot dimensions and acreage, owner name and mailing address, assessed value and tax history, zoning designation, flood zones and overlay districts.

This is the most accurate free boundary data available to you, and almost nobody thinks to look.

2. Google Maps and Google Earth

Open Maps, switch to Satellite in the Layers control, search your address and zoom in. Property lines appear in some regions and not others, and where they do they are approximate.

Google Earth's historical slider is the underused feature. It lets you scrub back through years of imagery for the same location, which is genuinely useful for seeing when a structure was built or removed, tracking neighbourhood development, settling a fence or tree question with a date, and checking what a property looked like before you bought it.

The capture date is usually shown in the lower corner of Google Earth. Most US urban areas refresh every one to three years; rural areas less often.

3. Bing Maps Bird's Eye View

The most underrated free aerial tool. Bird's Eye shows oblique aerial photography from four cardinal directions rather than straight down, so you can see the sides of buildings, roof pitch and elevation changes that a top-down view flattens.

Coverage is patchier than Google's, but where it exists it is the closest free equivalent to a drone shot.

4. USGS National Map Viewer (NAIP)

NAIP is the National Agriculture Imagery Program, flown by plane every two to three years during the growing season at roughly 60 cm per pixel. It is free, downloadable, and public domain.

To use it: open the National Map Viewer, click the Layers icon, tick Imagery (NAIP Plus), search your address and zoom in. The Markup or Palette tool lets you draw lines onto the image from your own survey, and you can export the result as JPG or PDF.

That export function is why NAIP is worth knowing about. It is the easiest way to produce a clean, printable image of your lot with your own annotations on it.

5. Parcel apps

Regrid has a free tier covering more than 157 million US parcels, with address search, owner information and lot dimensions over a satellite basemap. It is the best nationwide free alternative when your county portal is poor.

LandGlide (around $10/month) does GPS-based parcel lookups and is popular with land professionals. onX Hunt (around $30/year) is built for outdoor use but works for any boundary lookup, and is strongest in rural and western states. Both offer free trials.

Regrid Pro starts around $20/month for more detailed data.

None of these substitute for a survey. All of them are good for quick research, neighbour conversations and project planning.

6. State and regional aerial programs

Several states publish their own high-resolution orthophotos for free download, often sharper than anything national. Examples include PAMAP in Pennsylvania, NYS Orthos in New York, TNRIS in Texas and CalAtlas in California. Worth a search for your state before paying anyone.

Pick the right source for your job

For about 90% of what people want, Google Maps, Bing Bird's Eye and your county GIS are all you will ever need.

How accurate are these lines, really?

Four tiers, from roughest to definitive.

Google Maps overlay. Approximate. Off by several feet in many areas, absent in others. Fine for orientation, not for decisions.

County GIS or assessor data. Usually within a few feet, sometimes much closer. Accuracy depends on when the county last updated its parcel layer and how good its underlying survey control is.

A recorded plat or deed survey. Legally binding. This is a document, not a map layer, and you probably received one at closing.

A current licensed survey. The gold standard. A surveyor uses GNSS equipment and physical monuments to mark your actual corners. Typically $400 to $1,000.

The honest summary: accurate enough to plan, not accurate enough to build on without verification.

Sensor resolution, for reference

At 10 metres per pixel, a house occupies roughly one pixel. That is why the free scientific satellite archives, useful as they are for agriculture and climate work, will not show you your driveway.

If you want historical depth rather than resolution, USGS EarthExplorer holds Landsat scenes back to the 1970s and aerial imagery from the 1930s onward.

How to cross-check your property lines

Five steps. The third is the one most people skip.

• Find your plat or survey. Check your closing documents first, then the county clerk or recorder, then your title company. This is the authoritative document and you may already own it.

• Open your county GIS and compare the lot dimensions shown against the plat. They should agree closely. If they do not, trust the plat.

• Cross-check against a second source. Google Satellite plus one parcel app. Note where they disagree, because the disagreement tells you the margin of error you are working with.

• Walk the property. Look for survey monuments: iron pins or capped rebar at the corners, sometimes buried an inch or two under grass. A metal detector helps. Finding them converts an approximation into a fact.

• Hire a licensed surveyor if the sources disagree, if the markers do not match the map, or if you are building anywhere near a boundary.

Limitations worth knowing

Imagery age. What you are looking at could be three years old. New construction, a removed outbuilding or a recent lot split may not appear.

Parcel data lags. Splits, subdivisions and consolidations can take months or years to show up in the county layer.

Easements are usually invisible. Utility, drainage and access easements materially affect what you can build, and they generally do not appear in the parcel layer at all. They are in your title report.

Rural and tribal coverage is thin. Parcel data quality drops sharply outside metropolitan counties. The checkerboard public and private ownership pattern across much of the western US is often rendered badly or not at all.

Cloud cover and shadows distort detail, especially at oblique sun angles.

Commercial reuse needs permission. Public-agency imagery from USGS and NAIP is generally fine for personal and informational use, but reusing imagery commercially may require attribution or a licence.

And the one that matters most: online tools are not legal documents. No app's display will hold up in a property dispute the way a stamped survey will.

When to pay, and what for

Two entirely different price tiers get called "paid," and confusing them leads to bad quotes.

Consumer parcel apps: $10 to $30. LandGlide, onX, Regrid Pro. Better boundary data and offline GPS. Useful if you are checking multiple properties.

Commercial and professional imagery: hundreds to thousands. Archive imagery from Maxar, Planet or Airbus runs roughly $10 to $50 per square kilometre, more for a fresh tasking. Subscription services like Nearmap, EagleView, Vexcel and Hexagon start at a few hundred dollars a month for professional access.

Drone photography: $150 to $500 for a residential shoot, more for commercial property or video. This is the one most homeowners actually want, and it is the only option sharp enough for listing photography.

Underrated uses

• Solar and HVAC quoting. Many installers now quote remotely from aerial roof imagery without visiting.

• Spotting easements and encroachments before they become disputes: a neighbour's shed over the line, a utility right-of-way, a shared driveway.

• Pre-renovation planning. Architects use aerial views for setbacks, sun angles, tree positions and site access.

• Vacation rental marketing. An aerial showing proximity to a beach or ski run does more than any interior photo.

• Insurance documentation. A dated image of your roof before a storm is useful evidence afterwards.

If you are buying or selling a home

Buying. Before you visit, pull up the county GIS and Google Earth. You will see the lot shape, what backs onto the property, road access, tree cover, and how close the neighbours actually are. The historical slider tells you what has changed. This is fifteen minutes of due diligence that regularly changes people's minds about a viewing. Pair it with Wayber's home buying service when you are ready to move.

Selling. An aerial view genuinely helps buyers understand a lot, especially an unusual one. But be clear about what free imagery can and cannot do: it is good for context and orientation, and it is not sharp enough for listing photography. If you want an aerial image in your listing, book a drone shoot. At $150 to $500 it is one of the higher-return marketing spends available, and free satellite imagery is not a substitute.

If you are weighing how to sell, we cover listing your home on the NWMLS for a flat fee and have compared the flat-fee MLS services in Washington.

Frequently asked questions

Can I get a free satellite view of my house? Yes. Google Maps, Google Earth, Bing Maps, the USGS National Map Viewer and most county GIS portals all offer free satellite or aerial imagery of US residential properties.

What is the most accurate free property line map? Your county's GIS or assessor portal. The data comes directly from the tax assessor and is usually accurate within a few feet. Regrid's free tier is the best nationwide alternative where your county portal is poor.

Does Google Maps show accurate property lines? Not reliably. Boundaries appear in some regions and not others, and where they do appear they are approximate and can be off by several feet. Use them for orientation, not decisions.

Do satellite images show legal property lines? No. The imagery is a photograph; boundaries are a separate data layer from county records drawn over it. Only a licensed survey establishes legally binding boundaries.

Can I use a satellite map to settle a property line dispute? No. Online satellite maps and parcel overlays are not legally binding. A licensed surveyor is required to establish boundaries that hold up in a dispute.

What is the highest-resolution free imagery available? It depends where you are. Google and Bing typically reach 15 to 30 cm in urban areas. NAIP is around 60 cm but covers the entire country consistently and is downloadable. Several states publish free orthophotos sharper than either.

How recent is the imagery on these maps? Google refreshes most US urban areas every one to three years, rural areas less often. NAIP flies every two to three years. Commercial providers can supply imagery captured within weeks, for a fee.

What is the best free aerial view for a real estate listing? There is not one. No free source is sharp enough for listing photography. A drone shoot at $150 to $500 is the standard, and it is worth the money on any listing.

Can I use free satellite imagery in a listing? Public-agency imagery from USGS and NAIP is generally fine for personal and informational use, but commercial reuse may require attribution or a licence. For listing photos, drone or a licensed commercial provider is the safer route.
