Penyelidikan & liputan

This atlas connects dated building geometry, observed station reports, published transport counts and satellite/model context. It has no calibrated flood, smoke or structural solver and no complete operational asset register. A 3D view does not turn an estimate into a survey.

Atlas ini menghubungkan geometri bangunan bertarikh, cerapan stesen, jumlah pengangkutan diterbitkan dan konteks satelit/model. Tiada penyelesai banjir, asap atau struktur terkalibrasi, atau daftar aset operasi lengkap. Paparan 3D tidak menjadikan anggaran sebagai ukur sebenar.

Method / Kaedah

Building footprints: Overture release 2026-09-23, with source lineage retained. Height order: tagged height, floor inference, Google Open Buildings 2.5D (2023), GHSL area estimate (2018), class fallback. Inspect each building for its actual provenance. The map’s extrusions, facade detail and lighting are visual interpretations, not a building information model. Coverage is the baked study box, not all Greater KL.

Jejak bangunan: keluaran Overture 2026-09-23, dengan asal sumber dikekalkan. Ketinggian menggabungkan tag, inferens tingkat, Google 2.5D (2023), anggaran kawasan GHSL (2018) dan nilai lalai. Semak asal setiap bangunan. Ekstrusi, fasad dan pencahayaan ialah tafsiran visual, bukan model maklumat bangunan. Liputan ialah kotak kajian yang dibina, bukan seluruh Greater KL.

Observation currency / Kesemasaan cerapan

DOE API/IPU requires an enabled station and a reading no older than three hours, allowing five minutes of clock skew. JPS uses each gauge’s own level datum and threshold, with a 45-minute limit. The station list covers 3.02–3.26°N, 101.58–101.78°E, including some edges outside KL. It is not a reading at the user’s address. Failures and old readings stay unknown. The existing national relays own normalization.

IPU JAS memerlukan stesen aktif dan bacaan tidak melebihi tiga jam dengan toleransi jam lima minit. JPS menggunakan datum dan ambang setiap tolok, dengan had 45 minit. Senarai stesen meliputi 3.02–3.26°U, 101.58–101.78°T, termasuk pinggir di luar KL. Ia bukan bacaan di alamat pengguna. Kegagalan dan bacaan lama kekal tidak diketahui.

Satellite interpretation / Tafsiran satelit

Product availability comes from NASA WMTS metadata and is separate from the time this site checked it. A valid tile response may contain no usable local pixels. Cloud gaps are missing data. Browse colours are rendered products, not raw analytical arrays. LST is surface temperature in kelvin; subtract 273.15 for Celsius. NDVI is an eight-day vegetation composite. SMAP Level 4 soil moisture assimilates observations into a 9 km model. IMERG rate is mm/h, not daily accumulation. Do not infer street flooding, heat illness or smoke origin from these products.

Ketersediaan produk datang daripada metadata WMTS NASA, berasingan daripada masa semakan laman. Respons jubin sah mungkin tiada piksel setempat yang boleh digunakan. Jurang awan ialah data hilang. Warna ialah produk paparan, bukan tatasusunan analisis mentah. LST ialah suhu permukaan kelvin; tolak 273.15 untuk Celsius. NDVI ialah komposit lapan hari. SMAP Tahap 4 mengasimilasi cerapan ke dalam model 9 km. Kadar IMERG ialah mm/j, bukan jumlah harian. Jangan inferens banjir jalan, penyakit haba atau asal asap daripada produk ini.

Transport / Pengangkutan

Prasarana/MOT headline ridership counts trips, not unique people. This publication is audited monthly even though its rows are daily. Comparisons use two consecutive complete seven-day windows per service; missing dates or counts suppress the comparison. Holidays and service changes can explain a difference; the chart establishes no cause or current crowding.

Data Prasarana/MOT mengira perjalanan, bukan individu unik. Penerbitan diaudit bulanan walaupun baris harian. Perbandingan menggunakan dua tetingkap tujuh hari lengkap berturutan setiap perkhidmatan; tarikh atau nilai hilang menutup perbandingan. Cuti dan perubahan perkhidmatan boleh menjelaskan perbezaan, tanpa membuktikan sebab atau kesesakan semasa.

Next evidence / Bukti seterusnya

DBKL pond and pump registries, MyHijau gazettes, planning editions, Landsat thermal histories, Sentinel radar/optical scenes and land-cover classifications remain distinct candidates. Integrating them requires dates, usable geometry, reuse terms and local quality checks. No promise of exhaustive coverage, forecast calibration or an operational service-level agreement is made.

Daftar kolam dan pam DBKL, warta MyHijau, edisi rancangan, sejarah terma Landsat, adegan Sentinel dan pengelasan litupan tanah kekal calon berasingan. Integrasi memerlukan tarikh, geometri, syarat guna semula dan semakan kualiti setempat. Tiada janji liputan menyeluruh, kalibrasi ramalan atau tahap perkhidmatan operasi.
