How to See Property Lines on Google Earth, Step by Step

How to see property lines on Google Earth: download your county's free parcel KMZ or shapefile, open it in Google Earth and know how far to trust it.

How to see property lines on Google Earth comes down to one move: bring in your county’s own parcel map. Google Earth does not come loaded with the official parcel layer your county assessor keeps, but many counties offer that layer as a free download in KML, KMZ or shapefile format, and Google Earth opens all three. Once the file is loaded, you get parcel outlines draped over satellite imagery, and you can click a lot to see its parcel number and acreage. Below are the steps for Google Earth Pro on a computer and for Google Earth in a web browser, where to find the files and how far to trust the lines once they are on screen.

The short answer

1. Find your county’s parcel download. Look for a “GIS data download” page or an open data site, and pick the KMZ or KML version if one is offered.
2. Open it in Google Earth. In Google Earth Pro, use File > Open for KML/KMZ or File > Import for a shapefile. In Google Earth on the web, use Import file.
3. Save it. In Google Earth Pro, drag the layer from Temporary Places to My Places so it is still there next time.
4. Treat the lines as approximate. They are county mapping lines, not a survey.

Why you have to add the lines yourself

Google Earth is built around imagery, terrain and places. The boundary your county uses for tax bills lives in the county’s GIS, and each county maintains its own. Our post on why Google Earth does not show official lot lines covers that gap. The good news is that Google Earth was designed to read outside map data, so the county’s file drops right in.

Step 1: Find a parcel file you can download

Start on your county GIS or assessor website and look for links named “GIS data,” “data download,” “open data” or “Google Earth files.” Our land map points you to each county’s free GIS viewer, no login needed, which is a quick way to find the right office. A few real examples show what to look for:

• Plumas County, California has a page of KML/KMZ files made for Google Earth, including a “Property Parcels” layer with approximate boundaries, acreage and assessor parcel numbers. That layer leaves out owner names and was listed as updated in July 2026.
• Montezuma County, Colorado offers a Parcels.KMZ file for Google Earth alongside a parcel shapefile and geodatabase. The county says the parcel files are rebuilt nightly and include ownership data.
• Colusa County, California lists its tax parcels as both a shapefile ZIP and a KMZ. It updates that layer once a year after the fiscal year closes on June 30.

Many counties publish data through an ArcGIS Hub open data site instead. Esri’s documentation says those sites can usually offer feature layers as CSV, shapefile, GeoJSON and KML, and KML downloads from layers hosted in ArcGIS Online arrive as compressed KMZ files. Look for a Download button on the parcel layer’s page.

Which format to pick: choose KMZ or KML when you can. KML stores locations as plain latitude and longitude, so it lands in the right spot without any extra setup. A shapefile is a set of files (.shp, .shx, .dbf and usually .prj) that need to stay together, so unzip the whole download into one folder before importing.

Step 2a: Load it in Google Earth Pro (desktop)

Google Earth Pro is a free download for Windows, Mac and Linux that can import and export GIS data. One catch: Google’s download page warns that it stops offering the desktop program as a download on June 25, 2027. If you cannot install it, use the web steps below.

• KML or KMZ: choose File > Open and select the file, or simply double-click it once Google Earth Pro is installed. The parcels appear in the Places panel.
• Shapefile: choose File > Import, set the file type to ESRI Shape (.shp) and pick the .shp file. Google’s Earth Outreach tutorial explains that a file with more than 2,500 features triggers a prompt to import a sample, limit the import to the current view or import all. For a whole county, zooming to your area first and picking the current-view option keeps things fast.
• Style it: Google Earth then offers a style template. On the Name tab you can label each parcel with a field such as the parcel number; on the Color tab pick a single bright outline color that shows up against the imagery.
• Keep it: imported data starts in Temporary Places. Drag it into My Places before you close the program, or it will be gone next time.

Step 2b: Load it in Google Earth on the web

Google Earth in a browser can bring in county files too. Google’s documentation lists KML, KMZ, GeoJSON and zipped shapefiles as supported imports:

1. Open Google Earth in your web browser and sign in.
2. From the home screen, choose New, then Import file. Inside an open project, use File, then Import.
3. Pick the file from your computer or Google Drive.
4. Choose how to bring it in. Smaller KML/KMZ files, at most 10,000 features and 250,000 vertices, can come in as editable map features. Bigger files load as a data layer, which can be styled but not edited and counts against your Google Earth storage.

If you would rather not upload anything, Google Earth can also open a KML or KMZ file as a local file. It is not saved to a project, and it only shows on the device where you opened it.

Step 3: Read the parcel lines

• Click a parcel to see its attributes, such as the parcel number and acreage. Use that number to pull the full record from the assessor. Our guide on finding a parcel number by address shows the reverse lookup.
• Turn on historical imagery in Google Earth Pro if you want to see how fences, driveways or tree lines have changed over the years.
• Compare the shape with the plat. If the lot’s outline and lengths roughly match the recorded plat, the layer is probably a fair picture. If they do not, trust the plat. See survey plat vs tax map for how the two differ.

How accurate are the lines you see?

Loading a county file into Google Earth does not make it more precise. The lines are only as good as the county’s source data, and the imagery underneath has its own shifts. Plumas County’s download page says its parcel boundaries are graphical representations, not legal surveys, and that accuracy depends on the source, how the data was collected and when it was last updated. Montezuma County says its data shows relative positions only and is not a substitute for a survey by a licensed surveyor.

Timing matters too. A layer updated once a year, like Colusa County’s, may not show a split or a new lot from the past few months. Our guide to how accurate GIS maps are for property lines explains how far off county lines can be and how to judge yours.

If the lines do not show up or land in the wrong place

• Nothing appears: make sure the layer is checked in the Places panel, then double-click its name to fly to it. A large file may take a while to draw.
• Lines sit in the ocean or miles away: a shapefile may be missing its .prj file, so Google Earth cannot tell where the coordinates belong. Download the KMZ version instead, or the whole shapefile ZIP again.
• Only part of the county loads: you may have picked the current-view option. Pan to another area and import again, or import all.
• No download offered: use the county’s own online parcel viewer instead, or ask the GIS office whether a file is available.

What not to use it for

Parcel lines on Google Earth are great for getting your bearings, planning a walk of the property line or checking a listing before you visit. They are not good enough to set a fence, a shed or a driveway near the line. For that, find the corner pins (how to find property corners) or hire a licensed land surveyor to mark the boundary.
