DetectMap stands on official, public data. This page says which countries we really cover, from which sources, under which license and how fresh the data actually is. A country counts as supported only once all 6 points below are green — better 1 country covered for real than forty-five on paper.
Official registers are maintained by their operators (a ministry, the surveying authority). That date is in their hands — where the source publishes it, we show it; where it does not, we do not make it up.
Layers marked "live" are read straight from the official server on every query — with no intermediate, months-old copy. Our pre-rendered layers are labeled with their origin, and we manually verify each source and its license on the date listed with it.
Next to zones the app shows "Data updated X hours ago" — that is the time of the LAST download to your device (important for working without signal), not a claim about the freshness of the official register.
The map and the contours work all over the world. Our analytic layers — terrain, zones, parcels — only where we have really covered a country; each country below says so honestly.
The license does not forbid bulk downloads, but their terms of use allow usage only as long as we do not burden their server with bulk downloads — an offline package is exactly that. This layer therefore works only with a connection.
Our home country and the only one covered in depth: protected zones live from the official register, parcels, orthophoto 35 years back, LiDAR and a verified legal guide.
The app caches only the queried area, not the whole register. Written confirmation of the re-use terms is in progress.
We read the zones live from the official eVRD server on every query — no intermediate copy. Written confirmation of the re-use terms is being arranged; until then the license is labeled honestly.
Parcel lookups are not stored in offline packages; written confirmation of the terms is in progress.
Parcel lookups go live to the official server; query coordinates are not logged. The cadastre as a layer is published under CC BY 4.0; written confirmation for point lookups is still being arranged.
GURS publishes the map under CC BY 4.0; written confirmation for use in the app is in progress.
Pre-rendered layer from the open national DMR1; origin and license are listed with the layer.
The server is publicly accessible, but public accessibility is NOT a license. Until we have written confirmation of the re-use terms, the license is honestly labeled "under verification".
Has a verified legal guide (the Act was completely replaced in December 2024), but no Croatian data layer yet — which is why Croatia is NOT a supported country.
The legal guide is verified against the official text of the law and published, and the technical LiDAR pilot is measured on one tile near the Slovenian border from an open source (CC BY 4.0). The official Austrian hillshade layer (basemap.at) has been enabled on the web map since 30 Aug 2026 — but it is third-party and informational, not our analytic rendering. Our analytic layers and zones are still missing, so Austria is NOT a supported country.
Only a limited single online lookup is prepared. We have not verified a permitted offline workflow or scope for this source.
The server path is prepared but remains closed by default with AT_PARCEL_ENABLED. DKM_GST is a snapshot dated 1 Apr 2026, not a daily-live cadastre. Measurements return the cadastral-municipality code and parcel number; we do not promise the municipality name, official area, ownership or geometry.
Pilot measured on 30 Aug 2026 on one tile near the Slovenian border: the source is open (CC BY 4.0 license from the BEV catalog) and the pipeline works. The layer is NOT in the app yet — Austria becomes supported only once every point of the standard is green, including the legal guide. The series carries a cut-off date of 15 Sep 2019; a newer vintage is still to be verified.
The CC BY 4.0 license allows re-use, but their tile service is not meant for bulk downloads. Before we offer this layer offline, we verify this in writing.
Official Austrian terrain hillshade from 1 m data — NOT our analytic rendering, which is why it is labeled informational. Source verified on 30 Aug 2026 in the WMTS capabilities: layer `bmapgelaende`, style `grau`, JPEG, google3857, zoom 0–17, extent 8.78–17.5 E / 46.36–49.04 N. The layer has been enabled on the web map since 30 Aug 2026; the map credit line fulfils their condition — attribution with an active link to basemap.at. Tiles run through our server, which tonally aligns the source greys to the scale of our Slovenian layer: that is an adaptation under CC BY 4.0, while the terrain content stays theirs. The source also covers strips across the neighbouring countries, so we clip the layer to the national border (Eurostat GISCO 1:1 million, © EuroGeographics) — a cartographic mask for rendering, not a legal boundary.
On the list of neighbors after Austria and Croatia. The data is fragmented across regions, so the package will require assembly — until it exists, we promise nothing.
Only the viewed area is cached at the network edge; we verify the right to an offline package before offering one.
Shared EU layer (27 countries from one official source), enabled on the web map since 30 Aug 2026 — live from the EEA server through our proxy (EEA sends no CORS header; EEA’s pre-rendered cache dates from 2021, so freshness rules it out). A protected nature area is NOT an automatic metal detecting prohibition — the display always reads "protected area, check local rules", never an automatic red or green sign.
This is not legal advice and the app is not a permit. The official register and the legislation of the country you are searching in always take precedence — DetectMap helps you check, but the decision and the responsibility remain yours. Rules by country: legal guides. How we protect your data: privacy policy.
