Endpoint
heatmapTiles
menyediakan peta panas terkait serbuk sari melalui overlay ubin. Overlay ubin
adalah kumpulan ubin gambar yang dapat ditampilkan di atas Google Maps. Setiap
petak gambar berukuran 256 x 256 piksel.
Overlay petak adalah petak yang dirakit dari kumpulan petak, yang masing-masing diberi koordinat (X,Y). Ubin dengan koordinat (0,0) selalu berada di sudut barat laut peta. Nilai X bertambah dari barat ke timur, sedangkan nilai Y bertambah dari utara ke selatan.
zoom level menentukan seberapa besar atau kecil konten peta muncul dalam tampilan peta. Ukuran petak ubin ditentukan dengan menskalakan koordinat X dan Y
secara eksponensial berdasarkan tingkat zoom.
gridSizeX = XzoomLevel
gridSizeY = YzoomLevel
Misalnya, pada tingkat zoom 2, peta dunia direpresentasikan menggunakan matriks 4 x 4, dengan total 16 ubin.
Gambar berikut menunjukkan peta panas TREE_UPI seluruh dunia, yang dibagi menjadi ubin yang dapat diakses pada tingkat zoom 2.
Z: Tingkat zoom yang menentukan seberapa besar atau kecil konten peta
tampil di tampilan peta. Nilai yang diizinkan adalah 0-16, dengan nilai 0 menampilkan
seluruh dunia dalam satu petak.
X,Y: Koordinat petak relatif terhadap sudut timur laut (0,0). Nilai X
bertambah dari barat ke timur dan nilai Y bertambah dari utara ke
selatan. Koordinat harus valid untuk tingkat zoom yang ditentukan. Misalnya,
jika Anda menyetel tingkat zoom ke 2 dan meminta petak di koordinat (10,10),
API akan menampilkan error.
Contoh permintaan peta panas
Gambar di atas menunjukkan peta panas TREE_UPI dengan tingkat zoom 2, beserta
koordinat setiap petak. Contoh berikut menggunakan endpoint heatmapTiles
untuk meminta petak di koordinat (2,1):

A tile overlay\nis a collection of image tiles that can be displayed on top of Google Maps. Each\nimage tile is 256 x 256 pixels.\n\nThe tile overlay is a grid assembled from a collection of tiles, each assigned\n(`X`,`Y`) coordinates. The tile with coordinates (0,0) is always at the\nnorthwest corner of the map. The `X` values increase from west to east, while\nthe `Y` values increase from north to south.\n\nThe `zoom level` determines how large or small the contents of a map appear in a\nmap view. The tile grid size is determined by scaling the `X` and `Y`\ncoordinates exponentially by the zoom level. \n\n```text\ngridSizeX = XzoomLevel\ngridSizeY = YzoomLevel\n```\n\nFor example, at a zoom level of 2, the world map is represented using a 4 x 4\nmatrix, for a total of 16 tiles.\n\nThe following image shows a `TREE_UPI` heatmap of the entire world, sectioned\ninto tiles that can be accessed at a zoom level of 2.\n\nSee [Map and Tile\ncoordinates](/maps/documentation/javascript/coordinates#tile-coordinates) for\nadditional details.\n\nYou can request current pollen heatmap tiles using the [heatmapTiles](/maps/documentation/pollen/reference/rest/v1/mapTypes.heatmapTiles/lookupHeatmapTile)\nendpoint by sending an HTTP GET request to: \n\n```html\nhttps://pollen.googleapis.com/v1/mapTypes/TYPE/heatmapTiles/Z/X/Y?key=YOUR_API_KEY\n```\n\nAbout the heatmap endpoint\n--------------------------\n\nAll parameters listed below are required for a successful request:\n\n- `KEY`: Your application's API key. This key identifies your application for purposes of quota management. Learn how to [get a\n key](/maps/documentation/pollen/get-api-key).\n- `TYPE`: The type of heatmap to return. See [allowed\n values](/maps/documentation/pollen/reference/rest/v1/mapTypes.heatmapTiles/lookupHeatmapTile#maptype).\n- `Z`: Zoom level that determines how large or small the contents of a map appear in a map view. Allowed values are 0-16, where a value of 0 displays the entire world in a single tile.\n- `X`,`Y`: The tile coordinates relatively to the north east corner (0,0). `X` values increase from west to east and `Y` values increase from north to south. Coordinates must be valid for the specified zoom level. For example, if you set the zoom level to 2 and request a tile at coordinates (10,10), the API returns an error.\n\nExample heatmap request\n-----------------------\n\nThe image above shows a `TREE_UPI` heatmap with a zoom level of 2, along with\nthe coordinates of each tile. The following example uses the `heatmapTiles`\nendpoint to request the tile at coordinates (2,1): \n\n```html\nhttps://pollen.googleapis.com/v1/mapTypes/TREE_UPI/heatmapTiles/2/2/1?key=YOUR_API_KEY\n```\n\nThe tile appears as an image that can be overlaid on a map:\n\nFor more information on overlaying tiles on top of the default map, see\n[Overlay Map Types](/maps/documentation/javascript/examples/maptype-overlay)."]]
