# Būvklimatoloģijas karte

Interaktīva Latvijas būvklimatoloģijas karte Latvijas būvnormatīva LBN 003-19 "Būvklimatoloģija" tabulu datiem.

## Purpose

The project maps LBN 003-19 climate tables to Latvian climate reference points and Voronoi zones. A user can click any point in Latvia and inspect the nearest applicable station/place values for temperature, humidity, precipitation, icing, ground freezing, heating period, and solar radiation tables.

## Primary Pages And Files

- Main web app: `index.html`
- Public URL: https://buvklimats.skillup.lv/
- App logic: `app.js`
- Embedded table data: `data.js`
- Embedded Latvia boundary: `boundary.js`
- GeoJSON dataset documentation: `geojson-dataset/README.md`
- All station/table data: `geojson-dataset/stations-all-tables.geojson`
- All Voronoi/table data: `geojson-dataset/voronoi-all-tables.geojson`
- Station points only: `geojson-dataset/stations.geojson`
- Latvia boundary: `geojson-dataset/latvia-boundary.geojson`

## Dataset

The dataset contains tables 1-28 from LBN 003-19. Table-specific GeoJSON files are available as:

- `geojson-dataset/stations-table-{id}.geojson`
- `geojson-dataset/voronoi-table-{id}.geojson`

Where `{id}` is a table number from `1` to `28`.

Some LBN 003-19 tables do not contain values for all 22 station/place points. In table-specific GeoJSON exports, only stations with values for that table are included.

## Source

Table data is based on:

Ministru kabineta noteikumi Nr. 432, "Noteikumi par Latvijas būvnormatīvu LBN 003-19 Būvklimatoloģija".

The app notes that table data was collected from likumi.lv on 2026-05-07.

## Usage Notes

- Coordinates are place-center approximations used for visual map lookup, not official geodetic coordinates of meteorological stations.
- Voronoi zones are generated from available table station/place points and clipped to the Latvia boundary.
- The nearest applicable point is determined by the active table's station set.
