For this assignment, first provide a summary of the dataset using expss and then create a series of 4 maps that analyze locations and characteristics of landfills in the United States. See the "dictionary" tab on the Excel worksheet for variable information. Use must use leaflet for this assignment. Combining or recoding variables may improve your analysis.




The data are available from the Environmental Protection Agency (EPA) here: https://www.epa.gov/lmop/landfill-technical-data See the link named "Landfill-level data only." (Links to an external site.)


In one or more maps you must use:points with labels;a map legend;maps using radius (proportion to size) by referencing another variable;a polygon layer that is merged with data of your choice; anda rectangle layer to emphasize an area (use the counties or districts shapefiles provided in the Files section of this course, or another shapefile of your choice)a count of points in a subset of polygons, for a geographic region you wish to focus oninclude a photograph of trash that you see in your neighborhoodBe sure you create maps with attention to the design principles presented in class, and that show a variety of methods and layers to create a rich perspective on your data.
Each map should have an accompanying description that is detailed and clearly written.USE Ralso include an introduction, methods of data processing, analysis results, and conclusion thanks


Summary Count of Unique Landfills in this File 2,632 The LMOP Database contains key information about MSW landfills and LFG energy projects in the United States. Information in the LMOP Database is compiled from a variety of sources. Data received for inclusion in the LMOP Database are reviewed for reasonableness and are corroborated via other data sources when possible. Not all data are updated each year. While the Program strives to keep the information as updated and accurate as possible, the database is not exhaustive.
