You can find information about two different APIs, which are based on the open data of the Latvian State Land Service's Cadastre Information System and Estonian Land Board (Maa-amet). Information about the cadastral information layer WMS can be found here here.

Parcel and building search

Autocomplete search, that allows to find specific parcel (in Latvia or Estonia) or building (only in Latvia) by its cadastral number, and get their geometry.

API URL

The request URL should match the following pattern:

https://api.kartes.lv/v3//search?layers=cadastral

By default, the response is given in JSON (JSONP and XML are also available).

The HTTP GET request method is used.

Query parameters

The request consists of the following GET parameters:

Response parameters

The response consists of the queried cadastral number, its properties, CRS, with an array of objects with parameters defined by the fields parameter.

Defining a cadastral API class in JavaScript code:

class CadastreApi {
    constructor() {
        this.apiKey = 'your_api_key_here'; // Replace with your actual API key
        this.baseUrl = 'https://api.kartes.lv/v3';
    }

    // Method to fetch cadastral data
    async getCadastralData(query) {
        const searchParams = new URLSearchParams({
            q: query,
            fields: 'name,the_geom',
            format: 'geojson',
            layers: 'cadastral'
        });
        const url = `${this.baseUrl}/${this.apiKey}/search?${searchParams}`;

        try {
            const response = await fetch(url);

            // Check if the response is ok (status code 200-299)
            if (!response.ok) {
                throw new Error(`Error fetching data: ${response.statusText}`);
            }

            const data = await response.json();
            return { success: true, data };
        } catch (error) {
            console.error('Fetch error:', error);
            return { success: false, error: error.message };
        }
    }
}

Using the cadastral API class:

const api = new CadastreAPI();

api.getCadastralData('01000242161')
    .then(result => {
        if (!result.success) {
            console.error('Error:', result.error); // Handle the error
            return;
        }

        console.log(result.data);
        // Use the data
    });

Cadastral (parcel) reverse geocoding

Returns parcel number and extra properties for the given coordinates (location information).

By default, the response is given in JSON (JSONP and XML are also available).

The HTTP GET request method is used.

Query parameters

The request consists of the following GET parameters:

Response parameter

The response consists of a single element. It has following parameters:
