# Acuan API QuerySet GIS

## Pencarian Spasial

Pencarian spasial dalam bagian ini tersedia untuk [`GeometryField`](/id/5.0/ref/contrib/gis/model-api/#django.contrib.gis.db.models.GeometryField) dan [`RasterField`](/id/5.0/ref/contrib/gis/model-api/#django.contrib.gis.db.models.RasterField).

Untuk pengenalan, lihat the [spatial lookups introduction](/id/5.0/ref/contrib/gis/db-api/#spatial-lookups-intro).  Untuk sebuah tinjauan dari apa pencarian cocok dengan backend spasial tertentu, mengacu pada [spatial lookup compatibility table](/id/5.0/ref/contrib/gis/db-api/#spatial-lookup-compatibility).

### Pencarian dengan raster

Semua contoh dalam acuan dibawah diberikan untuk bidang-bidang dan masukan geometri, tetapi pencarian dapat menggunakan cara sama dengan raster pada kedua sisi. Kapanpun pencarian tidak mendukung amsukan raster, masukan otomatis dirubah ke geometri dimana dibutuhkan menggunakan fungsi [ST\_Polygon](https://postgis.net/docs/RT_ST_Polygon.html). Lihat juga [introduction to raster lookups](/id/5.0/ref/contrib/gis/db-api/#spatial-lookup-raster).

Penghubung basisdata digunakan oleh pencarian dapat dibagi menjadi tiga kategori:

- Raster asli mendukung `N`: penghubung menerima raster secara asli pada kedua sisi dari pencarian, dan masukan raster dapat dicampur dengan masukan geometri.
- Dukungan raster timbal balik `B`: penghubung mendukung hanya raster jika kedua sisi dari pencarian menerima masukan raster. Data raster otomatis dirubah menjadi geometri untuk pencarian campuran.
- Dukungan perubahan geometri `C`. Pencarian tidak memiliku dukungan raster asli, semua data raster otomatis dirubah ke geometri.

Contoh-contoh dibawah menunjukkan SQL setara untuk pencarian dalam jenis berbeda dari dukungan raster. Pola sama berlaku pada semua pencarian spasial.

| Kasus | Cari | Setara SQL |
| --- | --- | --- |
| N, B | `rast__contains=rst` | `ST_Contains(rast, rst)` |
| N, B | `rast__1__contains=(rst, 2)` | `ST_Contains(rast, 1, rst, 2)` |
| B, C | `rast__contains=geom` | `ST_Contains(ST_Polygon(rast), geom)` |
| B, C | `rast__1__contains=geom` | `ST_Contains(ST_Polygon(rast, 1), geom)` |
| B, C | `poly__contains=rst` | `ST_Contains(poly, ST_Polygon(rst))` |
| B, C | `poly__contains=(rst, 1)` | `ST_Contains(poly, ST_Polygon(rst, 1))` |
| C | `rast__crosses=rst` | `ST_Crosses(ST_Polygon(rast), ST_Polygon(rst))` |
| C | `rast__1__crosses=(rst, 2)` | `ST_Crosses(ST_Polygon(rast, 1), ST_Polygon(rst, 2))` |
| C | `rast__crosses=geom` | `ST_Crosses(ST_Polygon(rast), geom)` |
| C | `poly__crosses=rst` | `ST_Crosses(poly, ST_Polygon(rst))` |

Pencarian spasial dengan raster hanya didukung untuk backend PostGIS (dinamai sebagai PGRaster dalam bagian ini).

### `relate`

*Availability*: [PostGIS](https://postgis.net/docs/ST_Relate.html),
MariaDB, Oracle, SpatiaLite, PGRaster (Conversion)

Coba jika bidang geometri secara spasial terkait pada pencarian geometri dengan nilai-nilai diberikan dalam pola yang diberikan. Pencarian ini membutuhkan sebuah parameter tuple. `(geom, pattern)`; bentuk dari `pattern` akan bergantung pada backend spasial:

#### MariaDB, PostGIS, and SpatiaLite

Pada backend spasial ini pola persimpangan adalah sebuah string terdiri dari sembilan karakter, yang menentukan persimpangan diantara interior, batasan, dan eksterior dari bidang geometri dan pencarian geometri. Matriks pola persimpangan mungkin hanya menggunakan karakter: `1`, `2`, `T`, `F`, atau `*`.  Jenis pencarian ini mengizinkan pengguna untuk "fine tune" sebuah hubungan geometrik khusus sesuai dengan model DE-9IM. [^1]

Contoh geometri:

```
# A tuple lookup parameter is used to specify the geometry and
# the intersection pattern (the pattern here is for 'contains').
Zipcode.objects.filter(poly__relate=(geom, "T*T***FF*"))
```

PostGIS and MariaDB SQL equivalent:

```sql
SELECT ... WHERE ST_Relate(poly, geom, 'T*T***FF*')
```

SpatiaLite SQL setara:

```sql
SELECT ... WHERE Relate(poly, geom, 'T*T***FF*')
```

Contoh raster:

```
Zipcode.objects.filter(poly__relate=(rast, 1, "T*T***FF*"))
Zipcode.objects.filter(rast__2__relate=(rast, 1, "T*T***FF*"))
```

PostGIS SQL setara:

```sql
SELECT ... WHERE ST_Relate(poly, ST_Polygon(rast, 1), 'T*T***FF*')
SELECT ... WHERE ST_Relate(ST_Polygon(rast, 2), ST_Polygon(rast, 1), 'T*T***FF*')
```

#### Oracle

Disini hubungan pola adalah terdiri dari setidaknya satu dari sembilan hubungan string: `TOUCH`, `OVERLAPBDYDISJOINT`, `OVERLAPBDYINTERSECT`, `EQUAL`, `INSIDE`, `COVEREDBY`, `CONTAINS`, `COVERS`, `ON`, dan `ANYINTERACT`.   Banyak string mungkin dipadukan dengan penghubung Boolean logis OR, sebagai contoh, `'inside+touch'`. [^2]  Hubungan string adalah kasus-tidak-peka.

Contoh:

```
Zipcode.objects.filter(poly__relate=(geom, "anyinteract"))
```

Oracle SQL setara:

```sql
SELECT ... WHERE SDO_RELATE(poly, geom, 'anyinteract')
```

### `touches`

## Pencarian Jarak

*Ketersediaan*: PostGIS, Oracle, MariaDB, MySQL, SpatiaLite, PGRaster (Asli)

Untuk sebuah tinjauan pada melakukan permintaan jarak, hrap mengacu pada [distance queries introduction](/id/5.0/ref/contrib/gis/db-api/#distance-queries).

Distance lookups take the following form:

```text
<field>__<distance lookup>=(<geometry/raster>, <distance value>[, "spheroid"])
<field>__<distance lookup>=(<raster>, <band_index>, <distance value>[, "spheroid"])
<field>__<band_index>__<distance lookup>=(<raster>, <band_index>, <distance value>[, "spheroid"])
```

The value passed into a distance lookup is a tuple; the first two
values are mandatory, and are the geometry to calculate distances to,
and a distance value (either a number in units of the field, a
[`Distance`](/id/5.0/ref/contrib/gis/measure/#django.contrib.gis.measure.Distance) object, or a [query
expression](/id/5.0/ref/models/expressions/)). To pass a band index to the lookup, use
a 3-tuple where the second entry is the band index.

Pada setiap pencarian jarak kecuali [`dwithin`](#std-fieldlookup-dwithin), sebuah unsur pilihan, `'spheroid'`, mungkin disertakan untuk digunakan lebih akurat fungsi perhitungan jarak bulatan dengan sistem kordinat geodetik.

Pada PostgreSQL, pilihan `'spheroid'` menggunakan [ST\_DistanceSpheroid](https://postgis.net/docs/ST_Distance_Spheroid.html) daripada [ST\_DistanceSphere](https://postgis.net/docs/ST_DistanceSphere.html). Fungsi [ST\_Distance](https://postgis.net/docs/ST_Distance.html) paling sederhana digunakan dengan sistem kordinat yang sudah dihitung. Raster dirubah ke geometri untuk pencarian berdasarkan spheroid.

### `distance_gt`

Mengembalikan model-model dimana jarak pada bidang geometri dari geometri pencarian lebih besar dari nilai jarak yang diberikan.

Contoh:

```
Zipcode.objects.filter(poly__distance_gt=(geom, D(m=5)))
```

| Backend | Setara SQL |
| --- | --- |
| PostGIS | `ST_Distance/ST_Distance_Sphere(poly, geom) > 5` |
| MariaDB | `ST_Distance(poly, geom) > 5` |
| MySQL | `ST_Distance(poly, geom) > 5` |
| Oracle | `SDO_GEOM.SDO_DISTANCE(poly, geom, 0.05) > 5` |
| SpatiaLite | `Distance(poly, geom) > 5` |

### `distance_gte`

Mengembalikan model-model dimana jarak pada bidang geometri dari geometri pencarian lebih besar dari atau setara pada nilai jarak diberikan.

Contoh:

```
Zipcode.objects.filter(poly__distance_gte=(geom, D(m=5)))
```

| Backend | Setara SQL |
| --- | --- |
| PostGIS | `ST_Distance/ST_Distance_Sphere(poly, geom) >= 5` |
| MariaDB | `ST_Distance(poly, geom) >= 5` |
| MySQL | `ST_Distance(poly, geom) >= 5` |
| Oracle | `SDO_GEOM.SDO_DISTANCE(poly, geom, 0.05) >= 5` |
| SpatiaLite | `Distance(poly, geom) >= 5` |

### `distance_lt`

Mengembalikan model-model dimana jarak pada bidang geometri dari geometri pencarian kurang dari nilai jarak yang diberikan.

Contoh:

```
Zipcode.objects.filter(poly__distance_lt=(geom, D(m=5)))
```

| Backend | Setara SQL |
| --- | --- |
| PostGIS | `ST_Distance/ST_Distance_Sphere(poly, geom) < 5` |
| MariaDB | `ST_Distance(poly, geom) < 5` |
| MySQL | `ST_Distance(poly, geom) < 5` |
| Oracle | `SDO_GEOM.SDO_DISTANCE(poly, geom, 0.05) < 5` |
| SpatiaLite | `Distance(poly, geom) < 5` |

### `distance_lte`

Mengembalikan model-model dimana jarak pada bidang geometri dari geometri pencarian kurang dari atau setara pada nilai jarak yang diberikan.

Contoh:

```
Zipcode.objects.filter(poly__distance_lte=(geom, D(m=5)))
```

| Backend | Setara SQL |
| --- | --- |
| PostGIS | `ST_Distance/ST_Distance_Sphere(poly, geom) <= 5` |
| MariaDB | `ST_Distance(poly, geom) <= 5` |
| MySQL | `ST_Distance(poly, geom) <= 5` |
| Oracle | `SDO_GEOM.SDO_DISTANCE(poly, geom, 0.05) <= 5` |
| SpatiaLite | `Distance(poly, geom) <= 5` |

### `dwithin`

Mengembalikan model-model dimana jarak pada bidang geometri dari geometri pencarian dalam jarak yang diberikan dari satu lainnya. Catat bahwa anda hanya dapat menyediakan obyek [`Distance`](/id/5.0/ref/contrib/gis/measure/#django.contrib.gis.measure.Distance) jika geometri tersasar dalam sistem diperhitungkan. Untuk geometri geografis, anda harus menggunakan satuan dari bidang geometri (misalnya tingkatan untuk `WGS84`) .

Contoh:

```
Zipcode.objects.filter(poly__dwithin=(geom, D(m=5)))
```

| Backend | Setara SQL |
| --- | --- |
| PostGIS | `ST_DWithin(poly, geom, 5)` |
| Oracle | `SDO_WITHIN_DISTANCE(poly, geom, 5)` |
| SpatiaLite | `PtDistWithin(poly, geom, 5)` |

### Fungsi Kumpulan

Django menyediakan beberapa fungsi pengumpulan khusus-GIS. Untuk rincian pada bagaimana menggunakan fungsi-fungsi pengumpulan ini, lihat [the topic guide on aggregation](/id/5.0/topics/db/aggregation/).

| Argumen Katakunci | Deskripsi |
| --- | --- |
| `tolerance` | kata kunci ini adalah hanya untuk Oracle.  Itu adalah nilai toleransi digunakan oleh prosedur SDOAGGRTYPE\`; [Oracle documentation](https://docs.oracle.com/en/database/oracle/oracle-database/21/spatl/spatial-concepts.html#GUID-CE10AB14-D5EA-43BA-A647-DAC9EEF41EE6) mempunyai rincian lebih. |

Example:

```pycon
>>> from django.contrib.gis.db.models import Extent, Union
>>> WorldBorder.objects.aggregate(Extent("mpoly"), Union("mpoly"))
```

#### `Collect`

#### `class Collect(geo_field, filter=None)`

*Tersedia*: [PostGIS](https://postgis.net/docs/ST_Collect.html), SpatiaLite

Returns a `GEOMETRYCOLLECTION` or a `MULTI` geometry object from the geometry
column. This is analogous to a simplified version of the [`Union`](#django.contrib.gis.db.models.Union)
aggregate, except it can be several orders of magnitude faster than performing
a union because it rolls up geometries into a collection or multi object, not
caring about dissolving boundaries.

> **Changed in Django 5.0**
>
> Support for using the `filter` argument was added.

#### `Extent`

#### `class Extent(geo_field, filter=None)`

*Tersedia*: [PostGIS](https://postgis.net/docs/ST_Extent.html), Oracle, SpatiaLite

Returns the extent of all `geo_field` in the `QuerySet` as a 4-tuple,
comprising the lower left coordinate and the upper right coordinate.

Example:

```pycon
>>> qs = City.objects.filter(name__in=("Houston", "Dallas")).aggregate(Extent("poly"))
>>> print(qs["poly__extent"])
(-96.8016128540039, 29.7633724212646, -95.3631439208984, 32.782058715820)
```

> **Changed in Django 5.0**
>
> Support for using the `filter` argument was added.

#### `Extent3D`

#### `class Extent3D(geo_field, filter=None)`

*Tersedia*: [PostGIS](https://postgis.net/docs/ST_3DExtent.html)

Returns the 3D extent of all `geo_field` in the `QuerySet` as a 6-tuple,
comprising the lower left coordinate and upper right coordinate (each with x, y,
and z coordinates).

Example:

```pycon
>>> qs = City.objects.filter(name__in=("Houston", "Dallas")).aggregate(Extent3D("poly"))
>>> print(qs["poly__extent3d"])
(-96.8016128540039, 29.7633724212646, 0, -95.3631439208984, 32.782058715820, 0)
```

> **Changed in Django 5.0**
>
> Support for using the `filter` argument was added.

#### `MakeLine`

#### `class MakeLine(geo_field, filter=None)`

*Tersedia*: [PostGIS](https://postgis.net/docs/ST_MakeLine.html), SpatiaLite

Mengembalikan `LineString` dibangun dari geometri bidang titik dalam `QuerySet`. Saat ini pengurutan queryset tidak mempunyai pengaruh.

Example:

```pycon
>>> qs = City.objects.filter(name__in=("Houston", "Dallas")).aggregate(MakeLine("poly"))
>>> print(qs["poly__makeline"])
LINESTRING (-95.3631510000000020 29.7633739999999989, -96.8016109999999941 32.7820570000000018)
```

> **Changed in Django 5.0**
>
> Support for using the `filter` argument was added.

#### `Union`

#### `class Union(geo_field, filter=None)`

*Tersedia*: [PostGIS](https://postgis.net/docs/ST_Union.html), Oracle, SpatiaLite

Metode ini mengembalikan obyek [`GEOSGeometry`](/id/5.0/ref/contrib/gis/geos/#django.contrib.gis.geos.GEOSGeometry) terdiri dari gabungan dari setiap geometri dalam queryset. Harap catat bahwa penggunaan dari `Union` diolah secara intensif dan mungkin mengambil jumlah signifikan waktu pada queryset besar.

> **Note**
>
> Jika waktu perhitungan untuk menggunakan metode ini terlalu mahal, pertimbangkan menggunakan [`Collect`](#django.contrib.gis.db.models.Collect) sebagai gantinya.

Example:

```pycon
>>> u = Zipcode.objects.aggregate(Union(poly))  # This may take a long time.
>>> u = Zipcode.objects.filter(poly__within=bbox).aggregate(
...     Union(poly)
... )  # A more sensible approach.
```

> **Changed in Django 5.0**
>
> Support for using the `filter` argument was added.
