How This Site Turns
Public TV Data Into Search

This page explains the source datasets, sync flow, update cadence, and what a building-level coverage result can and cannot tell you.

OFCA DATA.GOV.HK CSDI Cloudflare D1

來源資料

OFCA 大廈級免費電視覆蓋

搜尋結果以 OFCA 的大廈級數碼地面電視覆蓋資料為核心,這是判斷大廈是否屬於可接收、邊緣接收或較弱覆蓋區域的主要依據。

CSDI 圖層與欄位核對

我們也會對照 CSDI Geoportal 與 API 文件,確認圖層、欄位及座標結構,確保搜尋及地圖使用的是最新公開資料。

Source Datasets

OFCA Building-Level Free TV Coverage

The lookup is anchored to OFCA's building-level digital terrestrial TV coverage dataset. That is the main source behind the Y, M, and X style result classes.

CSDI Layer And API Check

We also cross-check the CSDI geoportal and API documentation to confirm layer structure, fields, and location data before syncing.

同步流程

Step 1

拉取最新圖層

排程工作會取得最新公開資料,整理大廈名稱、地址、座標及覆蓋代碼,再統一成網站使用的欄位格式。

Step 2

寫入 Cloudflare D1

首頁搜尋 API、動態大廈頁及 sitemap 都直接讀取 D1,所以網站不是用靜態檔案硬編,而是即時查詢資料庫。

Step 3

每日同步更新

資料同步由排程自動觸發,更新後搜尋與動態頁面會使用最新結果,並持續輸出分頁 sitemap。

Sync Flow

Step 1

Pull The Latest Layer

A scheduled worker fetches the latest public layer and normalizes building names, addresses, coordinates, and coverage codes.

Step 2

Store It In Cloudflare D1

The search API, dynamic building pages, and sitemap all read from D1, so the site stays data-driven instead of being hard-coded.

Step 3

Refresh On A Daily Sync

The sync runs on schedule. Once updated, the homepage search and detail pages immediately use the latest stored result set.

這份資料可以與不可以回答甚麼

可以

幫你快速分辨某座大廈大致屬於可接收、邊緣接收,還是偏弱覆蓋區域。

不可以

不能保證每個單位、每個房間、每個插座、每部電視都一定有相同接收效果。

限制

它不會直接告訴你室內線路狀態,也不代表每座大廈只對應一個固定發射站或頻道組合。

What The Data Can And Cannot Tell You

Can

It helps you quickly see whether a building is broadly receivable, marginal, or in a weaker intended coverage area.

Cannot

It cannot guarantee identical reception for every flat, every room, every outlet, or every TV inside the building.

Limit

It does not directly reveal the in-flat wiring condition and does not assign one fixed transmitter or channel pack to every building.
