Counties were formerly administrative units across the whole of the UK. Due to various administrative restructurings, however, the only administrative areas still referred to as 'counties' are the Non-Metropolitan Districts of England. The English Metropolitan Districts, although no longer administrative units, are also used for statistical purposes.

The Counties area list contains 35 areas of the following constituent English geographies:

• 27 Shire counties
• 6 Metropolitan counties
• Inner London and Outer London

The boundaries are available as either extent of the realm (usually this is the Mean Low Water mark but in some cases boundaries extend beyond this to include off shore islands) or

clipped to the coastline (Mean High Water mark).

The V1 ('flying bomb' or 'doodlebug') and V2 (a ballistic missile) were two new weapons developed by Nazi Germany. In 1944 and 1945 thousands were fired at London. They killed thousands of people and injured many more.

This dataset includes all impact sites for V1s and V2s within the London County Council boundary. These were manually compiled from bomb maps published in 'The London County Council Bomb Damage Maps 1939-1945' by Laurence Ward (Thames and Hudson, 2015). The original LCC Bomb Damage maps are held at the London Archives.

**Please note that this is not a comprehensive dataset of all V1s and V2s. Only those within the London County Council boundary are included.**

We previously analysed this dataset in 'The flying bomb and the actuary', Significance (2019). doi: 10.1111/j.1740-9713.2019.01315.x

The impact sites can also be viewed as a layer on Google Maps. Data is separated into two layers: V1 sites and V2 sites. Each point represents an impact site, with the closest street name (to help with possible cross-reference) and page number in the LCC Bomb Damage Maps: https://www.google.com/maps/d/viewer?mid=1VwyxV_e_LAwzbyJPCAF-C7aCRVNA5W7N&ll=51.509018493447314%2C-0.05324588962980492&z=14

The Map & Collection currently holds about 60,000 paper air photos, focusing primarily on London and Southern Ontario. Holdings include print photos dating from 1922 to 2001 and are filed primarily by county. Air photo collections prior to 1969 are scanned, georeferenced and available for access through a custom web application.Collections dated post-1969 are available for viewing in the Library. Patrons should be aware of what can and cannot be copied by reviewing the Canadian Copyright Act. Copies of the Act and the agreement with the University are posted in the Map Collection. Please be aware that a 50 year copyright restriction applies. Air photos can be scanned at our scanning workstation at a resolution of your choice. Urban areas are very often found within the county coverage (ex. the town of Strathroy is included in Middlesex County). Specific urban places are also filed separately for quick reference, and on the Map and Data Centre's webpage. For questions please contact Western Libraries.

Geospatial Data Pack for Visualization 🗺️

Learn Geographic Mapping with Altair, Vega-Lite and Vega using Curated Datasets

Complete geographic and geophysical data collection for mapping and visualization. This consolidation includes 18 complementary datasets used by 31+ Vega, Vega-Lite, and Altair examples 📊. Perfect for learning geographic visualization techniques including projections, choropleths, point maps, vector fields, and interactive displays.

Source data lives on GitHub and can also be accessed via CDN. The vega-datasets project serves as a common repository for example datasets used across these visualization libraries and related projects.

Why Use This Dataset? 🤔

• Comprehensive Geospatial Types: Explore a variety of core geospatial data models:
  • Vector Data: Includes points (like airports.csv), lines (like londonTubeLines.json), and polygons (like us-10m.json).
  • Raster-like Data: Work with gridded datasets (like windvectors.csv, annual-precip.json).
• Diverse Formats: Gain experience with standard and efficient geospatial formats like GeoJSON (see Table 1, 2, 4), compressed TopoJSON (see Table 1), and plain CSV/TSV (see Table 2, 3, 4) for point data and attribute tables ready for joining.
• Multi-Scale Coverage: Practice visualization across different geographic scales, from global and national (Table 1, 4) down to the city level (Table 1).
• Rich Thematic Mapping: Includes multiple datasets (Table 3) specifically designed for joining attributes to geographic boundaries (like states or counties from Table 1) to create insightful choropleth maps.
• Ready-to-Use & Example-Driven: Cleaned datasets tightly integrated with 31+ official examples (see Appendix) from Altair, Vega-Lite, and Vega, allowing you to immediately practice techniques like projections, point maps, network maps, and interactive displays.
• Python Friendly: Works seamlessly with essential Python libraries like Altair (which can directly read TopoJSON/GeoJSON), Pandas, and GeoPandas, fitting perfectly into the Kaggle notebook environment.
