Client library for Geodata Pixel

Geodata Pixel Client

A Python client library for interacting with the Geodata Pixel API. Geodata Pixel is a SaaS solution for efficient image management, providing a centralized platform for uploading, storing, and structuring image data with geospatial information. This makes it easy to find and manage images based on time and location.

This client library provides a convenient interface for working with Geodata Pixel, allowing users to create projects, manage data collections, and upload and process various types of geospatial imagery including survey photos, drone imagery, 360° images, and raster data.

Geodata Pixel er vår løsning for effektiv bildeforvaltning. Med Geodata Pixel får du et felles sted å laste opp, lagre og strukturere bildedata, noe som gjør det enkelt å finne bilder basert på tid og sted.

Features

• Dual API Support: Both synchronous and asynchronous interfaces
• Data Management: Create and manage projects and data collections
• Image Handling: Upload and process image data with geolocation
• Raster Data Handling: Support for various raster data types (RGB, DTM, DSM)
• ArcGIS Services: Create and manage ArcGIS Feature and Image services
• Harvest Services: Automated data harvesting from ArcGIS Feature services
• Authentication: Integrated Keycloak authentication
• Metadata Management: Flexible metadata handling for uploaded files
• Attachments: Add and manage file attachments to resources

Installation

Warning This package is not yet available on PyPI. You can install it from the source code repository instead.

pip install pixel-client

Requirements

• Python 3.11 or higher

Authentication

The Pixel client requires authentication through Keycloak. You can provide authentication details through environment variables, a .env file, or directly in code:

from pixel_client import get_client, PixelApiSettings

# Using environment variables
client = get_client()

# Using direct settings
settings = PixelApiSettings(
    PIXEL_TENANT="your_realm",
    PIXEL_USERNAME="your_username",
    PIXEL_PASSWORD="your_password"
)
client = get_client(settings=settings)

# Using a .env file
settings = PixelApiSettings.from_env_file("my_env_file.env")
client = get_client(settings=settings)

Quick Start

Synchronous Usage

from pixel_client import get_client
from geojson_pydantic import Polygon

# Initialize the client
client = get_client()

# Create a project
new_project = client.create_project(
    name="My New Project",
    description="A test project",
    area_of_interest=Polygon.model_validate({
        "type": "Polygon",
        "coordinates": [[[-10, 10], [-10, 20], [0, 20], [0, 10], [-10, 10]]]
    }),
    tags=["test", "example"]
)

# Create a data collection
data_collection = client.create_data_collection(
    project_id=new_project["id"],
    name="My Data Collection",
    description="An example data collection",
    data_collection_type="image",
    tags=["example", "images"]
)

Asynchronous Usage

import asyncio
from pixel_client import get_client
from geojson_pydantic import Polygon

async def main():
    # Initialize the async client
    client = get_client(async_=True)
    
    # Create a project
    new_project = await client.create_project(
        name="My Async Project",
        description="A test async project",
        area_of_interest=Polygon.model_validate({
            "type": "Polygon",
            "coordinates": [[[-10, 10], [-10, 20], [0, 20], [0, 10], [-10, 10]]]
        }),
        tags=["test", "async"]
    )
    
    # Create a data collection
    data_collection = await client.create_data_collection(
        project_id=new_project["id"],
        name="My Async Data Collection",
        description="An example async data collection",
        data_collection_type="image",
        tags=["example", "async"]
    )

asyncio.run(main())

Uploading Data

Image Data

from pixel_client import get_client, PixelUploadFile, MetadataObject, ImageMetadataFields
from pathlib import Path

client = get_client()

# Upload images to a data collection
image_files = [
    PixelUploadFile(
        file=Path("path/to/image.jpg"),
        metadata=MetadataObject(
            fields=ImageMetadataFields(name="my_image"),
            json_metadata={"custom_field": "value"}
        )
    )
]

images, errors = client.upload_multiple_images(
    project_id=project_id,
    data_collection_id=data_collection_id,
    files=image_files
)

Raster Data

The client supports various raster data types:

• raster: Generic raster data
• RGB: RGB raster data (3 or 4 bands, uint8)
• DTM: Digital Terrain Model data (single band, float32/float64)
• DSM: Digital Surface Model data (single band, float32/float64)
