eMapa user guide

The screen has three parts. On the left is a panel with two tabs. Across the top is the toolbar. The rest is the map. The picture marks every button you will use; each one is described in detail further down.

Drag the map to move it. Zoom with the mouse wheel or the + and − buttons. The 3D button turns on terrain and buildings in three dimensions (see the next chapter). The compass turns the map back to north.

My location moves the map to where you are. Your browser asks for permission first. On the right of the toolbar you see the coordinates under the cursor and the current zoom.

eMapa remembers where you left off: next time, the map opens at the same place.

The 3D button turns the map three-dimensional: mountains, valleys and the coastline take their real shape, and buildings from the cadastre rise above the ground. It is the quickest way to see how a parcel sits on the land — on a slope, in a hollow or under a hill — before you go there.

The terrain comes from the Copernicus EU-DEM elevation model (the European Earth-observation programme) and NASA SRTM satellite measurements. Route with elevation uses the same heights. Heights are gently exaggerated (1.5×) so the shape of the land reads better.

The Layers tab holds all the data, in groups: base maps, orthophoto, cadastre, administrative boundaries, PPCG 2040, water, telecoms, topography, addresses, nature and ecology, risks.

Every layer has its own settings. The most used are opacity and, for parcels, showing each parcel's number and area right on the map.

Find a parcel by its number, or a building by its address.

Click a parcel on the map. The Info tab shows the parcel number, coordinates and area, the cadastral details (district, cadastral municipality, municipality), the land use set by the PPCG 2040 spatial plan and the environmental constraints that apply at that location.

The Environment block in the Information tab is collapsed. Its header shows the number of findings, the soil type and a water sign when the parcel is in a flood zone or a water-source zone. Click the header to open it.

Protection and risks are computed over the whole parcel, not the clicked point: protected nature, environmental pressures, PPCG 2040 protection zones, flood zones, water-source protection zones (zones I, II and III) and soil type. Each zone shows the share of the parcel it covers.

Below are terrain (elevation, slope, aspect), land cover (trees, grassland, cropland, built-up) with canopy density and the broadleaf and conifer share, what satellites see growing on the parcel and within about 1 km, the growing season, soil properties (pH, organic matter, texture, nitrogen, available water), crops that suit the climate and soil, with sowing months and whether rain alone is enough, and the solar plant yield and wind.

The printer button in the block header opens the Parcel environmental report — a separate A4 document with the same data, ready to print or save as PDF.

On a computer you can select several parcels together: hold Ctrl (Cmd on a Mac) and click the parcels. All selected parcels are highlighted on the map and listed in the panel.

An ordinary click without Ctrl selects a single parcel again.

The cadastre button ("Podaci iz katastra") loads the official records from eKatastar, the Real Estate Administration's system: the property sheet (LN) or land holding sheet (PL), right holders with their shares, parcel parts, buildings, encumbrances and restrictions, and pending applications.

The Other property button next to an owner's name shows what else that person holds, in every municipality.

For survey reports (elaborati), eMapa gives the coordinates of a parcel's corner points in three coordinate systems and three formats.

Cadastre statistics add up parcels, land and buildings in a chosen area: by cadastral municipality or settlement, or inside a boundary you draw. It is meant as groundwork for planning documents. The result is a set of tables, notes on data coverage and freshness, and a PDF report.

The report also shows what the area overlaps, with the area, the share of the boundary and the number of parcels in each zone: land use under PPCG 2040; protection zones and spatial restrictions (protected nature, UNESCO, military use, mineral resources, hydrocarbons); environmental constraints (national parks, the Emerald network, vulnerable and sensitive areas) with the number of polluters, discharges, landfills and treatment plants inside the area; flood zones for floods expected once in 10, 100 and 500 years; water-source protection zones (zones I, II and III, with the source name); and soil types from the soil map.

The Environment, terrain and farming block sums up the whole area, weighted by parcel area: average elevation and slope, the share of steep ground, land cover, forest density, what satellites see growing, soil pH, the growing season, suitable crops, solar plant yield and wind.

The statistics page itself describes the method in detail. Calculating requires signing in.

To plan a walk, a hike or a road alignment: length, ascent, descent, slope and the elevation profile.

Export takes what is on the map right now. For a more detailed export, zoom in first.

The PPCG 2040 group shows the Spatial Plan of Montenegro to 2040: land use, protected areas, planned infrastructure, renewable energy and spatial restrictions.

When a layer is on, its legend appears under it. Clicking a parcel tells you in the Info tab which land use applies to it.

The Water group shows rivers, catchments, groundwater, monitoring stations and flood zones for floods expected once in 10, 100 and 500 years. The colour of a flood zone shows the water depth.

The Nature and ecology group shows air quality, bathing water quality, protected areas, environmental pressures, soil types, forest cover and the pollen forecast.

The Risks group shows active fires, earthquakes from the last 30 days and drought. Clicking a station or an area shows its details and the data source.

Fire mode shows active fires from satellite imagery and water sources for firefighting. The panel lists the fires with burned area, fire power and the time of the latest satellite pass.

Sea mode shows bathing water quality at 114 public beaches, from the official sampling. Each beach has a grade (excellent, good, satisfactory, poor), the sampling date and the water temperature.

Install app in the red header adds eMapa to the home screen of your phone or computer as a separate app.

We are an independent project, not a state body. It grew out of a simple task: to open access to cadastre data for everyone.

Then we saw a common problem. There is no ready-made solution for this task. Each municipality gets its own funding and builds its own solution. These solutions are completely different, and they cannot be brought together. The appearance can be improved, but nobody will use such a service anyway. It looks nice, but it is not clear who it is made for.

We start from needs, not from beauty. Function comes first: what a citizen, a surveyor, an architect or a designer needs. Our map also looks good, but we do not need excess decoration. We could add it, but it slows the map down, and then nobody uses it.

Our goal is to bring the data about Montenegro together again in one place. Access to it must be fast and simple.

Everything you see is the result of work with planning specialists, surveyors, architects, other professionals and ordinary people. We are always open to cooperation.
