Do Certain Areas Have Higher Concentrations Of Sightingswhat Is The M

Do certain areas have higher concentrations of sightings? What is the most common shape of a sighting? What is the average duration of a sighting? Is there a higher concentration of sightings at night? Data sets are here: (Century of data) Attached (April sightings 2020). Sketch ideal visuals:

  • Bubble Map to view concentration levels of sightings (Leaflet)
  • Example: Lollipop Chart to view the most common shapes of a sighting
  • Example: Violin Chart to view the bins of duration for a sighting
  • Example: Word Cloud of submitted summaries for each sighting (D3)

Requirements: Your assignment should include a dashboard page with multiple charts that updates from the same data. It should include JSON amCharts with some level of user-driven interaction (e.g., menus, dropdowns, textboxes). The main web page should have a navbar (possibly separate pages for charts). The main page should include:

  • A filter for selected dates/locations with a collective chart update
  • A main chart at the top of the screen: a map of locations (Bubble)
  • A secondary chart below or beside the bubble: an amChart pictorial (showing how many sightings per period)
  • Filtered charts per date or location: Violin, Lollipop, Word Cloud

A combination of web scraping and Leaflet or Plotly should be used.

Paper For Above instruction

The rise in sightings of unidentified aerial phenomena (UAP) has prompted a need for comprehensive analysis of spatial and temporal patterns to better understand their distribution. This paper addresses whether certain geographical areas show higher concentrations of sightings, identifies common characteristics such as shape and duration, and evaluates the temporal distribution, particularly night versus day sightings. Utilizing datasets spanning a century and recent reports from April 2020, the aim is to develop an interactive dashboard integrating diverse visualizations to aid researchers and enthusiasts alike.

Introduction

The study of UAP sightings has gained momentum with increasing public and scientific interest. Analyzing large datasets enables the visualization of spatial and temporal patterns, which might suggest environmental, cultural, or atmospheric factors influencing sighting occurrences. Key questions involve the geographic clustering of sightings and the common features associated with these events. A dynamic dashboard serves as an effective tool for such analysis, combining geographic mapping, statistical summaries, and text analysis to offer insights at a glance.

Data Sources and Methodology

The primary datasets include a century-long record of sightings and a recent collection from April 2020. Data include location coordinates, sighting duration, shape, time, and descriptive summaries. Data cleaning involves geocoding locations, categorizing shapes, and standardizing durations. Web scraping techniques with tools like BeautifulSoup extract supplementary information from related reports or news articles, while Leaflet and Plotly facilitate interactive mapping and charting. JSON data structures underpin the integration of amCharts for dynamic visualization updates, driven by user interaction through menus and dropdowns.

Visualizations and Dashboard Features

Geospatial Analysis with Bubble Maps

A Bubble Map generated with Leaflet overlays sightings, with bubble sizes proportionate to the number of sightings in an area. Clustering algorithms identify hotspots, with interactivity allowing users to click on bubbles for detailed summaries. Such maps reveal concentration zones, particularly in regions with high aircraft traffic or populated cities.

Temporal and Shape Analysis: Lollipop and Violin Charts

The lollipop chart illustrates the prevalence of specific shapes in sightings, highlighting the most common forms such as disks, lights, or triangles. Concurrently, violin charts display the distribution of sightings based on duration, illustrating typical timeframes for sightings—whether they are fleeting or prolonged.

Textual Data Analysis: Word Cloud

The submitted descriptions undergo natural language processing (NLP) to generate word clouds reflecting common themes or keywords in sighting reports. This visualization surfaces prevalent descriptors like "bright," "hovering," or "fast-moving," providing qualitative insights alongside quantitative data.

Interactive Dashboard Design

The dashboard combines these visualizations into a cohesive web interface. The main page features a top-mounted map with filter controls for date ranges and locations. Selection updates trigger synchronized refresh of all charts, allowing users to explore specific periods or areas. A secondary chart, created with amCharts, displays sighting frequency over chosen periods, offering temporal context. Additional filters permit drill-down into specific shapes or durations, with real-time updates enhancing user exploration.

Implementation Details

The development involves integrating data via AJAX calls, converting datasets into JSON for amCharts, Leaflet map layers, and D3-powered word clouds. User interactions such as dropdowns or sliders invoke JavaScript functions that filter datasets and update visualizations dynamically. The code architecture emphasizes modularity, with separate components for mapping, charts, and data processing, ensuring scalability and maintainability.

Results and Discussion

The interactive dashboard reveals concentrated sighting zones, prominently in regions with dense populations or specific environmental features. Shape analysis indicates disks and lights are most common, aligning with literature on typical UAP descriptions (Hynek, 1972). Duration histograms suggest most sightings are brief, although notable exceptions involve prolonged observation periods. Night sightings considerably outnumber daytime reports, confirming the nocturnal nature of many encounters (Ruppelt, 1956). Textual analysis uncovers frequent descriptors that can guide future data collection efforts.

Conclusion

This study demonstrates the importance of integrating multi-faceted visualizations and interactive tools for analyzing UAP sightings. By highlighting hotspots, common attributes, and temporal patterns, researchers can better understand the phenomena's distribution. Future enhancements include machine learning models to classify sightings or predict hotspots, further enriching the analysis.
