Datasets¶
Create an image dataset¶
To create an image dataset:
>>> my_dataset = sdk.datasets.create_image_dataset(name='My Image',
... project=PROJECT_ID,
... mission=MISSION_ID,
... geometry={'type': 'Point', 'coordinates': [LONGITUDE, LATITUDE]},
... width=IMAGE_WIDTH_IN_PIXELS,
... height=IMAGE_HEIGHT_IN_PIXELS)
See the datasets.create_image_dataset() documentation.
And upload the image file:
>>> file_to_upload = "/path/to/image/file.jpg"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='image',
... file_path=file_to_upload)
See the datasets.upload_file() documentation.documentation.
Create a point cloud dataset¶
To create a point cloud (pcl) dataset:
>>> my_dataset = sdk.datasets.create_pcl_dataset(name='My PCL',
... project=PROJECT_ID,
... mission=MISSION_ID)
See the datasets.create_pcl_dataset() documentation.
And upload the pcl file:
>>> file_to_upload = "/path/to/pcl/file.las"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='pcl',
... file_path=file_to_upload)
See the datasets.upload_file() documentation.
Create a vector dataset¶
To create a vector dataset with a specific CRS (here UTM 32631):
>>> my_dataset = sdk.datasets.create_vector_dataset(
... name='My Vector',
... project=PROJECT_ID,
... mission=MISSION_ID,
... dataset_format='shapefile',
... is_archive=True,
... horizontal_srs_wkt='PROJCS["WGS 84 / UTM zone 31N",GEOGCS["WGS 84",[...]')
... # Full WKT available on http://epsg.io/32631.wkt
See the datasets.create_vector_dataset() documentation.
And upload the vector file (here a shapefile):
>>> file_to_upload = "/path/to/vector/shapefile.zip"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='archive',
... file_path=file_to_upload)
See the datasets.upload_file() documentation.documentation.
Create a mesh dataset¶
To create a mesh dataset with two texture files (and one material file, which is the default value):
>>> my_dataset = sdk.datasets.create_mesh_dataset(name='My Mesh',
... project=PROJECT_ID,
... mission=MISSION_ID,
... texture_count=2)
See the datasets.create_mesh_dataset() documentation.
And upload the mesh files:
>>> mesh_file = "/path/to/mesh/file.obj"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='mesh',
... file_path=mesh_file)
>>> first_texture = "/path/to/mesh/texture_a.jpg"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='texture_0',
... file_path=first_texture)
>>> second_texture = "/path/to/mesh/texture_b.jpg"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='texture_1',
... file_path=second_texture)
>>> material_file = "/path/to/mesh/material.mtl"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='material',
... file_path=material_file)
See the datasets.upload_file() documentation.documentation.
Create a raster dataset¶
To create a raster dataset with a world file and a projection file:
>>> my_dataset = sdk.datasets.create_raster_dataset(name='My Raster',
... project=PROJECT_ID,
... mission=MISSION_ID,
... has_projection_file=True,
... has_worldfile=True)
See the datasets.create_raster_dataset() documentation.
And upload the raster files:
>>> raster_file = "/path/to/raster/file.tif"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='raster',
... file_path=raster_file)
>>> world_file = "/path/to/raster/worldfile.tfw"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='worldfile',
... file_path=world_file)
>>> projection_file = "/path/to/raster/projection.prj"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='projection',
... file_path=projection_file)
See the datasets.upload_file() documentation.documentation.
Create a file dataset¶
To create a file dataset with several files:
>>> my_dataset = sdk.datasets.create_file_dataset(name='My File',
... project=PROJECT_ID,
... mission=MISSION_ID,
... file_count=2)
See the datasets.create_file_dataset() documentation.
And upload the dataset files:
>>> first_file = "/path/to/pcl/file.csv"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='file_0',
... file_path=first_file)
>>> second_file = "/path/to/pcl/file.pdf"
>>> sdk.datasets.upload_file(dataset=my_dataset.id,
... component='file_1',
... file_path=second_file)
See the datasets.upload_file() documentation.
Describe a dataset¶
>>> my_dataset = sdk.datasets.describe(DATASET_ID)
See the datasets.describe() documentation.
Describe a list of datasets¶
>>> my_dataset_list = sdk.datasets.describe([DATASET_ID, ANOTHER_DATASET_ID])
See the datasets.describe() documentation.
Download a preview¶
To download a preview of for a raster or image dataset:
>>> sdk.datasets.download_preview(dataset=DATASET_ID)
See the datasets.download_preview() documentation.
