What is checked

An hour is green only if every source has answered

And none of them has anything to report. Not knowing is not an authorisation: if a source cannot be reached, botic says so and names what the silence leaves open, rather than counting doubt as a green light.

The geographical zones at that hour

Not “right now”. A military area closed in the morning may open in the afternoon, and the other way round. Source: the official droneguide feed.

The upper limit actually allowed

Often far lower than the 120 m of the Open category: 35 ft near some military areas, 150 ft under an approach path.

Nature reserves

Absent from every drone map. Queried separately from the SPW, the Agentschap Natuur en Bos and Brussels Environment.

Weather, daylight and warnings

Wind, gusts, rain and visibility hour by hour, the sunrise–sunset window, and skeyes Daily Warnings within a 15 km radius.

In three steps

An address, a time slot, your aircraft

The rest is cross-checking — the kind of work nobody wants to redo by hand before every flight.

You place the point

An address or a click on the map. Zone lower limits published in MSL are converted using the real terrain elevation, never assumed.

You give the time

The intended time slot, not the present moment. Every source is queried for that hour, and the whole day is rendered hour by hour.

You get what is missing

Not just a light. The constraint that blocks, the margin under the upper limit, the authorisation to request — and from whom.

The app

Nearly 800 zones, cross-checked live

Screenshots taken in botic, unstaged. The number of zones changes from day to day: they are re-read from the official feed, not frozen into a map.

botic's map covering Belgium, saturated with orange and red geographical zones, with the navigation rail on the left and the layers panel on the right. — **What the Belgian sky really hides**The geographical zones at the requested hour, the aerodromes, the nature reserves of the three regions, the obstacles. Each layer switches on separately.

Zone sheet for EBLG VLL2: no authorisation to request, height limited by article 31, Open-category upper limit of 150 feet. — **The upper limit, not just the zone**Here, EBLG VLL2: no authorisation to request, but an actual upper limit of 150 ft — a quarter of the 120 m the Open category leads you to expect.

botic's hourly verdict: one bar per hour from 05:00 to 19:00, green for favourable, brown for caution, with the no-go and caution thresholds drawn as dotted lines. — **The hourly verdict, as is**One bar per hour between sunrise and sunset, the letter carrying the full verdict for the slot — wind, gusts, wind at 120 m, rain, visibility.

Georeferenced drone photo

Official boundaries, drawn on your photo

botic overlays the cadastre, buildings, zoning plan or flood zones on a drone photo, vertical or oblique, taking the terrain relief into account. For a mandate, neighbouring plots can be blurred.

Oblique aerial view with plots, existing buildings and roads drawn on the photo, and a numbered legend. — **Plots, buildings and roads**Oblique view at 120 m over a building site: cadastral boundaries, existing buildings, roads, north, scale and legend of the visible plots.

Oblique aerial view where only the plots of the mandate are sharp and the rest of the photo is blurred. — **Only the mandate's plots stay sharp**The rest of the photo is blurred: an agency shows only what it is mandated to show.

For estate agencies

“Where does the land end?” The answer is on the photo, with the official cadastral area, north, scale and the dated source.

Official sources

Cadastre and buildings: FPS Finance. Zoning plan, flood hazard, agricultural plots, relief: SPW. Flemish and Brussels equivalents. Every image carries its sources.

An indicative overlay

The overlay replaces neither a cadastral extract nor a boundary survey, and every image says so.

Limits

What botic does not do

A stated limit is worth more than an assumed coverage. Here is the one that matters.

NOTAMs are not cross-checked geographically

Their text is semi-structured and their position not always usable. They must be consulted separately before every flight — botic reminds you at every verdict rather than pretending it has read them. skeyes Daily Warnings, on the other hand, are filtered by radius and by time slot.

botic is not an official source and issues no authorisation. Only map.droneguide.be is authoritative in Belgium. Responsibility for the flight remains entirely the remote pilot's.
