# aiocogeo [](https://circleci.com/gh/geospatial-jeff/aiocogeo/tree/master)[](https://codecov.io/gh/geospatial-jeff/aiocogeo)
## Installation
```
pip install aiocogeo
# With S3 filesystem
pip install aiocogeo[s3]
```
## Usage
COGs are opened using the `COGReader` asynchronous context manager:
```python
from aiocogeo import COGReader
async with COGReader("http://cog.tif") as cog:
...
```
Several filesystems are supported:
- **HTTP/HTTPS** (`http://`, `https://`)
- **S3** (`s3://`)
- **File** (`/`)
### Metadata
Generating a [rasterio-style profile](https://rasterio.readthedocs.io/en/latest/topics/profiles.html) for the COG:
```python
async with COGReader("https://async-cog-reader-test-data.s3.amazonaws.com/lzw_cog.tif") as cog:
print(cog.profile)
>>> {'driver': 'GTiff', 'width': 10280, 'height': 12190, 'count': 3, 'dtype': 'uint8', 'transform': Affine(0.6, 0.0, 367188.0,
0.0, -0.6, 3777102.0), 'blockxsize': 512, 'blockysize': 512, 'compress': 'lzw', 'interleave': 'pixel', 'crs': 'EPSG:26911', 'tiled': True, 'photometric': 'rgb'}
```
#### Lower Level Metadata
A COG is composed of several IFDs, each with many TIFF tags:
```python
from aiocogeo.ifd import IFD
from aiocogeo.tag import Tag
async with COGReader("https://async-cog-reader-test-data.s3.amazonaws.com/lzw_cog.tif") as cog:
for ifd in cog:
assert isinstance(ifd, IFD)
for tag in ifd:
assert isinstance(tag, Tag)
```
Each IFD contains more granular metadata about the image than what is included in the profile. For example, finding the
tilesize for each IFD:
```python
async with COGReader("https://async-cog-reader-test-data.s3.amazonaws.com/lzw_cog.tif") as cog:
for ifd in cog:
print(ifd.TileWidth.value, ifd.TileHeight.value)
>>> 512 512
128 128
128 128
128 128
128 128
128 128
```
More advanced use cases may need access to tag-level metadata:
```python
async with COGReader("https://async-cog-reader-test-data.s3.amazonaws.com/lzw_cog.tif") as cog:
first_ifd = cog.ifds[0]
assert first_ifd.tag_count == 24
for tag in first_ifd:
print(tag)
>>> Tag(code=258, name='BitsPerSample', tag_type=TagType(format='H', size=2), count=3, length=6, value=(8, 8, 8))
Tag(code=259, name='Compression', tag_type=TagType(format='H', size=2), count=1, length=2, value=5)
Tag(code=257, name='ImageHeight', tag_type=TagType(format='H', size=2), count=1, length=2, value=12190)
Tag(code=256, name='ImageWidth', tag_type=TagType(format='H', size=2), count=1, length=2, value=10280)
...
```
### Image Data
The reader also has methods for reading internal image tiles and performing partial reads. Currently only jpeg, lzw, deflate, packbits, and webp compressions are supported.
#### Image Tiles
Reading the top left tile of an image at native resolution:
```python
async with COGReader("https://async-cog-reader-test-data.s3.amazonaws.com/webp_cog.tif") as cog:
x = y = z = 0
tile = await cog.get_tile(x, y, z)
ifd = cog.ifds[z]
assert tile.shape == (ifd.bands, ifd.TileHeight.value, ifd.TileWidth.value)
```
#### Partial Read
You can read a portion of the image by specifying a bounding box in the native crs of the image and an output shape:
```python
async with COGReader("https://async-cog-reader-test-data.s3.amazonaws.com/webp_cog.tif") as cog:
assert cog.epsg == 26911
partial_data = await cog.read(bounds=(368461,3770591,368796,3770921), shape=(512,512))
```
#### Internal Masks
If the COG has an internal mask, the returned array will be a masked array:
```python
import numpy as np
async with COGReader("https://async-cog-reader-test-data.s3.amazonaws.com/naip_image_masked.tif") as cog:
assert cog.is_masked
tile = await cog.get_tile(0,0,0)
assert np.ma.is_masked(tile)
```
### Configuration
Configuration options are exposed through environment variables:
- **INGESTED_BYTES_AT_OPEN** - defines the number of bytes in the first GET request at file opening (defaults to 16KB)
- **HEADER_CHUNK_SIZE** - chunk size used to read header (defaults to 16KB)
- **ENABLE_BLOCK_CACHE** - determines if image blocks are cached in memory (defaults to TRUE)
- **ENABLE_HEADER_CACHE** - determines if COG headers are cached in memory (defaults to TRUE)
- **HTTP_MERGE_CONSECUTIVE_RANGES** - determines if consecutive ranges are merged into a single request (defaults to FALSE)
- **BOUNDLESS_READ** - determines if internal tiles outside the bounds of the IFD are read (defaults to TRUE)
- **BOUNDLESS_READ_FILL_VALUE** - determines the value used to fill boundless reads (defaults to 0)
- **LOG_LEVEL** - determines the log level used by the package (defaults to ERROR)
- **VERBOSE_LOGS** - enables verbose logging, designed for use when `LOG_LEVEL=DEBUG` (defaults to FALSE)
- **AWS_REQUEST_PAYER** - set to `requester` to enable reading from S3 RequesterPays buckets.
Refer to [`aiocogeo/config.py`](https://github.com/geospatial-jeff/aiocogeo/blob/master/aiocogeo/config.py) for more details about configuration options.
