Overview

  • The Detection Process system helps you analyze aerial imagery to identify potential illegal dump sites.
  • This guide walks you through the complete workflow from uploading images to viewing detection results.

Managing Input Images

Accessing the Input Images Page

  1. Navigate to the Detection section in the main menu
  2. Click on "Detection Input Images"
  3. The system displays a list of all available input images

Uploading New Images

  1. Click the "Add Input Image" button
  2. Fill in the required information:
    • Name: Enter a descriptive name for the image
    • Description: Add relevant details about the image
    • Date Taken: Select when the image was captured
    • Image File: Click "Choose File" to select your image
  3. Click "Upload" to start the upload process
  4. Wait for the progress bar to complete
  5. The system will automatically generate a thumbnail

Managing Existing Images

  • Preview: Click the preview button (eye icon) to view the image
  • Edit: Use the edit button (pencil icon) to modify image details
  • Delete: Click the delete button (trash icon) to remove an image

    Note: You cannot delete images that are associated with existing detection runs

Creating Detection Runs

Starting a New Detection Run

  1. Navigate to "Create Detection Run" in the Detection section
  2. Fill in the detection run details:
    • Name: Enter a descriptive name for the detection run
    • Description: (Optional) Add additional information
    • Select Trained Model: Choose from available trained models
    • Select Input Image: Choose the image to analyze

Choosing Detection Parameters

  1. Select a trained model:
    • Models are listed with their training dates
    • Published models appear at the top of the list
  2. Select an input image:
    • Hover over image names to view details
    • Preview thumbnails are available
  3. Click "Schedule Detection" to start the process

Monitoring Detection Progress

  1. The system will display the current status:
    • Waiting: Detection run is queued
    • Processing: Analysis is in progress
    • Success: Detection completed successfully
    • Error: Detection encountered problems
  2. You can track progress in the Map Interface

Managing Ignore Zones

Creating Ignore Zones

  1. Open the Ignore Zones tool in the map interface
  2. Click "Add Ignore Zone"
  3. Draw the zone on the map:
    • Click to start drawing
    • Click for each corner point
    • Double-click to finish
  4. Fill in zone details:
    • Name: Enter a descriptive name
    • Description: Add purpose or notes
    • Enabled: Toggle zone activation

Using Ignore Zones

  • Active ignore zones automatically filter detection results
  • Areas within ignore zones are marked differently in results
  • Toggle zones on/off to adjust detection visibility

Viewing Detection Results

Accessing Results

You can view results in two ways:

  1. Historic Data View:

    • Click the History tool in the map interface
    • Select detection runs to display
    • Adjust confidence thresholds using sliders
    • Compare multiple detection runs

  2. Detection Zones List:

    • Navigate to "Detected Zones" in the menu
    • View all completed detection runs
    • Click to show individual run results

Understanding Result Display

Results are color-coded:

  • Red polygons: Detected dump sites outside ignore zones
  • Blue polygons: Detected sites within ignore zones
  • Confidence rates are displayed on each detection
  • Hover over detections for additional details

Filtering and Analysis

  1. Use confidence rate sliders to filter results
  2. Compare multiple detection runs:
    • Select runs to compare
    • Use the "Area Comparison" report
    • View statistics and metrics

Exporting Results

  1. Select detection runs to export
  2. Choose export format (if available)
  3. Download results for external use

Troubleshooting

Common Issues

  1. Upload Failures

    • Check file format compatibility
    • Verify file size limits
    • Ensure proper georeferencing

  2. Detection Errors

    • Verify input image quality
    • Check trained model compatibility
    • Review error messages in logs

  3. Display Problems

    • Refresh the map view
    • Clear browser cache
    • Check layer visibility settings

Getting Help

  • Check error messages for specific guidance
  • Contact system administrators for persistent issues
  • Document steps that led to any errors

Best Practices

  1. Input Images

    • Use high-resolution imagery
    • Ensure proper georeferencing
    • Keep file sizes manageable

  2. Detection Runs

    • Use descriptive names
    • Document run parameters
    • Monitor progress regularly

  3. Result Analysis

    • Start with default confidence thresholds
    • Compare multiple runs for accuracy
    • Document significant findings

  4. System Performance

    • Limit concurrent detection runs
    • Clean up unused data
    • Regular system maintenance
