Selling raw land is a harder marketing problem than selling a building. There is no kitchen to photograph, no lobby to walk a buyer through, no rent roll to hand over. What you are actually selling is a vision of the future, something like: this corner will be worth more in five years than it is today.
Take the 120 acres on Nemours Parkway in Orlando, listed at $42 million. The specs tell you what you are buying: 105 developable acres, PD zoning, utilities at the border, 3,800 feet of frontage on a four-lane road. They do not tell you why it costs that. A 1995 photo of the same ground does. It is pine flatwoods and pasture with nothing built for miles. Everything since then happened around the parcel, not to it.
What you are looking at
Six aerials of the same ground sit in the sidebar under Years, from 1995 to 2025. Click any one and it drops over the map. The parcel boundary stays exactly where it is, so you always know which piece of land you are looking at.
| Year | What changed |
|---|---|
| 1995 | Pine flatwoods and pasture. Original topography and drainage, nothing built vertically anywhere nearby. |
| 2006 | First grading and clearing. The arterial road corridors get their alignment and master planning begins. |
| 2010 | Tavistock Lakes Blvd opens and Lake Nona Medical City goes up, including the UCF College of Medicine. |
| 2015 | Nemours Children’s Hospital and the VA Medical Center finish. The block becomes a regional medical hub. |
| 2021 | Subdivisions and commercial centers fill in around it. The parcel is the largest contiguous piece still open. |
| 2025 | Four-lane frontage, utilities stubbed to the border, the institutional buildout complete. |
Each year opens a short card explaining what to look for, so the buyer is not left to interpret a grainy photo on their own.
The parcel pin carries the rest: APN, 120 acres with 105 developable, $42 million at $350,000 an acre, PD zoning for mixed-use, medical and multi-family, up to 1,200 units or 1.2 million square feet of commercial, utility status, frontage on both roads, and a Schedule Site Tour button underneath. The photos get the buyer interested, and the button is right there while they still are.
Nobody had to be told this submarket matured. They watched it happen in six clicks.
Why old aerials are worth the effort
- They make growth something the buyer sees. Every land listing claims proximity to growth. Few show it. Three or four dates side by side turn your claim into an observation, and buyers who discount your projections will not discount a photograph.
- They show work already done on the site. Old grading, a cleared access road, a stubbed utility line, a pond dug and never used. All of it trims a buyer’s site work budget, and all of it is easy to miss under twenty years of regrowth.
- They get the environmental question out of the way early. Aerials are a standard source in ASTM E1527 Phase I assessments because they reveal past uses that records miss. If you raise it yourself in week one, you shorten diligence and show you are not hiding anything. If you leave it, a consultant finds it in week six.
- They back up what you say about drainage. Wet-year imagery shows where water actually pools and which patterns have held. If your parcel drains well, the photo record makes that case better than a line in the brochure.
- They date the infrastructure. The year the interchange opened, the sewer trunk went in, the first big box store was built. Line those up against the parcel and your pricing has a timeline behind it.
- They give a rezoning a precedent. If the parcel needs a rezone, showing the surrounding block move from agricultural to commercial over twenty years helps the buyer, and later it helps you at the planning commission.
Building one in Mapme
You do not need GIS software or a consultant for this. The georeferencing guide covers the mechanics in full, so here is the short version.
- Start with the parcel. Add a pin with acreage, price, zoning and your contact details, then outline the boundary with the drawing tools. That polygon does more work here than on a normal map, because it is the one thing holding still while everything underneath it changes.
- Add each aerial as its own Image Layer. Under Layers > Overlay, choose Add Drawings or Images, select Image, and name it by year. Drag it into place, rotate to match, then switch to Free transform so you can pull each corner independently until the permanent features line up. Road intersections, river bends and rail lines are your best anchors, since buildings get demolished. Older frames from the 1930s to 1960s are usually distorted at the edges, so get the alignment right near the parcel and let the outer edges drift. A soft photo sitting exactly under the boundary will always beat a sharp one floating forty feet off.
- Turn the years into filters. Create a category for each year and set its Image Layer to appear only when that category is selected. Your buyer now has a row of year buttons, and clicking through them runs the site’s history against a boundary that never moves. That interaction is doing the selling, so it is worth getting right.
- Write a caption for every year. An Image Layer can open a location card on click. Use it to say what changed and why it matters. “2015 aerial” is a date. “Children’s hospital and VA Medical Center complete, block becomes a regional medical hub” is a reason to pay $350,000 an acre.
- Hang the diligence file off the parcel pin. Locations take PDFs, images, video and embedded 3D or 360 tours in one gallery, so the survey, topo study, utility letters and drone flyover can all live there. The link you send to a wide list on day one is then still the right link for a serious buyer in week six.
One exception: if your aerial is very large or you already have a georeferenced GeoTIFF, a custom tileset under Appearance > Basemap > Custom Tilesets will load faster and stay sharper. Tilesets do not support the visibility rules or click actions above, so they suit a wide regional image rather than the year toggle. Mapme’s professional services team can handle georeferencing and hosting on eligible plans if you would rather not.
Where to find the imagery
Most of it is free, though coverage varies by location and decade, so it is worth checking a few sources for any given parcel.
Start with your county or state GIS portal. Counties fly their own imagery on a regular cycle and publish it, and this is the most commonly overlooked source. From there, USGS EarthExplorer holds the largest public US archive going back to the 1930s, USDA NAIP is strong on recent decades and rural parcels, the National Archives covers roughly 1918 to 2011, and many university map libraries have digitized regional collections. Google Earth Pro is the quickest way to check whether a useful frame exists at all before you go hunting for a better copy.
If the free sources come up short, NETR Historic Aerials sells orthorectified GeoTIFFs that align themselves, Nearmap and EagleView cover recent years at high resolution, and LightBox EDR or ERIS are worth it only if the deal is already heading toward a Phase I.
Four to six dates is usually plenty. Pick the years when something actually happened rather than even intervals, and make sure the last one is recent so the story ends in the present.
The point
Your buyer is underwriting a future that has not happened yet. Everything you can show them that already happened makes that leap smaller.
Historical imagery will not close a deal on its own. What it does is take the neighborhood off the table as something the buyer has to take your word for, which leaves you negotiating price, terms and timing instead of credibility.
