LandsMaps: the Land Department's free online tool to check a Koh Phangan plot's real boundaries before you even view it

Is there a free way to check whether a piece of land marketed on Koh Phangan actually has a real, registered boundary before you spend time and money viewing it? Yes — the Land Department's own LandsMaps portal (landsmaps.dol.go.th) and its SmartLands mobile app let anyone search the national parcel database directly, at no cost, 24 hours a day. It's a genuinely useful first-pass screening step this site's own due-diligence checklist doesn't currently name, and a natural companion to D-Value, the Treasury Department's own online appraised-value lookup — LandsMaps for the boundary and deed status, D-Value for the value figure.

What LandsMaps actually shows

• Deed number, survey sheet/block reference, and the subdistrict, district and province the parcel sits in.
• The parcel's area in rai-ngan-square-wah, overlaid on satellite imagery so you can see the actual boundary shape against real terrain.
• The Treasury Department's official assessed land value for the parcel.
• GPS coordinates and directions/contact details for the relevant local Land Office branch.

It deliberately does not show the current owner's name, for privacy reasons — LandsMaps is a boundary-and-classification tool, not an ownership register.

Searching without a deed number — the part that matters most on Phangan

Plenty of Phangan land, especially hillside and remote plots, is marketed by a GPS pin or "near [landmark]" rather than a deed number a buyer can plug straight in. LandsMaps supports this directly: alongside the standard province/district/deed-number search, you can navigate the map itself (zoom and click, much like any consumer mapping app) or search by proximity to a known landmark. That map-first search is exactly what lets a buyer check, before ever meeting a seller, whether a pinned location actually corresponds to a titled parcel with a real registered boundary at all — the question at the heart of the untitled sea-view land scam guide, where marketed "land" turns out to be an unregistered PBT5 or Sor Por Kor claim with no chanote boundary LandsMaps could ever show.

What it doesn't do

• It isn't complete legal information — the Land Department's own guidance is explicit that data must be verified against the actual title deed, and LandsMaps itself is not a substitute for a certified copy pulled at the Land Office.
• It won't show a mortgage, a Section 83 caveat (see the caveat guide), a pending court injunction (see the injunction guide), or a forest-reserve/national-park boundary overlap — those need a proper Land Office title search, not a map lookup.
• Boundary lines on older or rural surveys can carry conversion imprecision when digitised — treat the shown polygon as indicative, not survey-grade, and still have a licensed surveyor walk the actual plot.
• It doesn't tell you anything about the seller, the price, or whether a company holding the land has a foreign-shareholding problem — those are separate checks covered elsewhere on this site.

None of this replaces a lawyer's title search or a surveyor's on-the-ground walk before you sign anything — see what a Phangan property lawyer's fee actually buys. But as a free, instant, zero-commitment first check on whether a marketed plot is what it claims to be, LandsMaps is worth using before you book a flight to view it.
