Produk data Area Terbakar MCD64A1 Versi 6.1 gabungan Terra dan Aqua adalah produk bulanan global dengan petak 500 m yang berisi informasi per piksel tentang area terbakar dan kualitas. Pendekatan pemetaan area terbakar MCD64A1 menggunakan gambar Pantulan Permukaan MODIS 500 m yang dipadukan dengan pengamatan kebakaran aktif MODIS 1 km. Algoritma ini menggunakan indeks vegetasi (VI) yang sensitif terhadap kebakaran untuk membuat nilai minimum dinamis yang diterapkan pada data gabungan.
VI berasal dari band pantulan permukaan yang dikoreksi secara atmosferik inframerah gelombang pendek MODIS 5 dan 7 dengan ukuran tekstur temporal.
Algoritma mengidentifikasi tanggal pembakaran untuk sel petak 500 m dalam setiap petak MODIS. Tanggal dienkode dalam satu lapisan data sebagai
hari ordinal tahun kalender saat kebakaran terjadi, dengan
nilai yang ditetapkan ke piksel lahan yang tidak terbakar dan nilai khusus tambahan
yang dicadangkan untuk data yang tidak ada dan sel petak air.
Hari pembakaran dalam setahun. Nilai yang mungkin: 0 (tidak terbakar), 1-366
(perkiraan hari Julian saat terbakar).

Bit 0: Daratan/perairan
0: Sel petak air
1: Sel petak darat
Bit 1: Tanda data valid. Nilai 1 menunjukkan bahwa ada
cukup data valid dalam deret waktu reflektansi agar sel
petak dapat diproses. (NB Sel petak Air akan selalu menghapus bit ini.)
0: Data valid tidak cukup
1: Data valid yang memadai
Bit 2: Periode pemetaan yang dipersingkat. Flag ini menunjukkan bahwa
periode pemetaan yang andal tidak mencakup periode produk
satu bulan penuh, yaitu, pembakaran tidak dapat dipetakan secara andal selama
satu bulan kalender penuh.
0: Periode pemetaan tidak diperpendek
1: Periode pemetaan diperpendek
Bit 3: Sel petak diberi label ulang selama fase pemberian label ulang kontekstual algoritma.
0: Sel petak tidak diberi label ulang
1: Sel petak diberi label ulang
Bit 4: Bit cadangan
0: T/A
Bit 5-7: Kode kondisi khusus yang dicadangkan untuk sel petak yang tidak terbakar.
Kode ini memberikan penjelasan untuk sel petak yang
diklasifikasikan secara ringkas sebagai tidak terbakar oleh algoritma deteksi karena
keadaan khusus.
0: Tidak ada atau tidak berlaku (yaitu, sel petak yang terbakar, tidak dipetakan, atau petak air).
1: Pengamatan valid yang terlalu jarang dalam waktu.
2: Terlalu sedikit pengamatan pelatihan atau pemisahan spektral yang tidak memadai antara kelas terbakar dan tidak terbakar.
3: Tanggal pembakaran yang jelas pada batas deret waktu.
4: Pencemaran air yang terlihat jelas.
5: Hotspot persisten.
6: Dipesan untuk penggunaan mendatang.
7: Dipesan untuk penggunaan di masa mendatang.

The MCD64A1 burned-area mapping approach employs\n500m MODIS Surface Reflectance imagery coupled with 1km MODIS active\nfire observations. The algorithm uses a burn sensitive vegetation index (VI)\nto create dynamic thresholds that are applied to the composite data.\nThe VI is derived from MODIS shortwave infrared atmospherically corrected\nsurface reflectance bands 5 and 7 with a measure of temporal texture.\nThe algorithm identifies the date of burn for the 500m grid cells within\neach individual MODIS tile. The date is encoded in a single data layer as\nthe ordinal day of the calendar year on which the burn occurred, with\nvalues assigned to unburned land pixels and additional special values\nreserved for missing data and water grid cells.\n\nDocumentation:\n\n- [User's Guide](https://lpdaac.usgs.gov/documents/1006/MCD64_User_Guide_V61.pdf)\n\n- [Algorithm Theoretical Basis Document (ATBD)](https://lpdaac.usgs.gov/documents/115/MCD64_ATBD_V6.pdf)\n\n- [General Documentation](https://ladsweb.modaps.eosdis.nasa.gov/filespec/MODIS/61/MCD64A1)\n\n### Bands\n\n\n**Pixel Size**\n\n500 meters\n\n**Bands**\n\n| Name | Min | Max | Pixel Size | Description |\n|---------------|-----|-----|------------|---------------------------------------------------------------------------------------------|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|\n| `BurnDate` | 0 | 366 | meters | Burn day of year.
