​

Getting Started

​

Installing the QGIS Plugin

1. Download Plugin: Available from Nika’s plugin repository
2. Install in QGIS: Use QGIS Plugin Manager
3. Configure Connection: Set up your Nika workspace
4. Test Integration: Verify data transfer capabilities

​

Basic Workflow

# Example: Export QGIS layer to Nika
from qgis.core import QgsProject
from nika_plugin import NikaExporter

# Get active layer from QGIS
layer = iface.activeLayer()

# Initialize Nika exporter
exporter = NikaExporter(workspace_id="your-workspace")

# Export with full styling
exporter.export_layer(
    layer=layer,
    preserve_styling=True,
    include_metadata=True
)

​

Advanced Integration

# Example: Automated data synchronization
from nika_plugin import SyncManager
from qgis.core import QgsProject

# Set up project monitoring
sync = SyncManager(
    qgis_project=QgsProject.instance(),
    nika_workspace="your-workspace",
    auto_sync=True
)

# Monitor for changes and sync automatically
sync.start_monitoring()

​

​

Advanced Features

​

Custom Processing Chains

# Example: Custom QGIS processing with Nika output
from qgis.core import QgsProcessing
from nika_plugin import NikaProcessor

# Define custom processing chain
def custom_analysis():
    # QGIS processing steps
    result = processing.run("native:buffer", {
        'INPUT': layer,
        'DISTANCE': 100,
        'OUTPUT': 'memory:'
    })
    
    # Export to Nika for web visualization
    nika_processor = NikaProcessor()
    nika_processor.upload_result(result['OUTPUT'])

​

Real-time Data Feeds

# Example: Real-time sensor data integration
from nika_plugin import RealTimeConnector

# Connect to real-time data source
connector = RealTimeConnector(
    source_type="sensor_network",
    update_interval=60  # seconds
)

# Update QGIS layer with live data
connector.update_qgis_layer(layer_name="sensor_data")

​
