Revisiting UK’s bicycle thefts. The data comes from https://data.police.uk/. The date ranged used was from May 2017 through April 2020. All surrounding police forces were used to obtain a comprehensive list of bicycle theft incidents. Previous post from 2016 can be found here. Carto was used to render the maps. Cities include: London, Manchester, Birmingham, and Bristol

If you would like to create your own UK crime maps, and are frustrated at the way data.police.uk presents its data. You may use this simple C# console application to aggregate it yourself. Simply paste the downloadables into a directory called LONDON4, and use the script below to generate an output file containing incidents from multiple police forces. Cheers.
C# Console Application
string dirPath = @"C:\LONDON4\"; List dirs = new List(Directory.EnumerateDirectories(dirPath)); Dictionary<string, int> dictUniqueCrime = new Dictionary<string, int>(); foreach (var dir in dirs) { Console.WriteLine("{0}", dir.Substring(dir.LastIndexOf("\\") + 1)); string filepath = @"C:\LONDON4\"; filepath += dir.Substring(dir.LastIndexOf("\\") + 1); Console.WriteLine(filepath); string line; string[] fileEntries = Directory.GetFiles(filepath); foreach (string fileName in fileEntries) { Console.WriteLine(fileName); System.IO.StreamReader file = new System.IO.StreamReader(fileName); while ((line = file.ReadLine()) != null) { string[] parts = line.Split(','); string month = parts[1]; string longitude = parts[4]; string latitude = parts[5]; string crimetype = parts[9]; if (crimetype == "Bicycle theft") { string lines = month + "-1, " + longitude + ", " + latitude + ""; System.IO.StreamWriter file1 = new System.IO.StreamWriter("C:\\Airplanes\\____BRITISHBICYCLES.csv", true); file1.WriteLine(lines); file1.Close(); } } file.Close(); } } |
