Contents Introduction Getting Started Folder Contents Metadata System Requirements For More Information, Contact GIS Play Maps Geographic Information System (GIS) representation of coal-bearing areas in India and Bangladesh By Michael H. Trippi and Susan J. Tewalt Introduction This report provides digital geographic information systems (GIS) files of maps representing the geographic locations of coal and lignite fields in India and Bangladesh, and point sample locations with geochemical and petrographic data in each nation. Maps showing the areal extent of coal and lignite fields in India and Bangladesh were prepared by USGS geologists. Coal and lignite field polygons were captured by digitizing previously published paper and online maps. For more details about the original sources and the methods used to digitize these maps please read the text portion of this Open-File Report. Getting Started The GIS shapefiles are bundled in a single downloadable zip file called IndiaBangladeshOFR.zip. To install: Download IndiaBangladeshOFR.zip (6.75 megabytes of hard-drive space required) to local hard drive Open with Winzip or other zip utility and click the “Extract” button (highlighting of the individual files is not necessary) Extract contents to a destination on the local hard drive Five folders will be created called BangladeshAnalyticalData, BangladeshCoalfields, IndiaAnalyticalData, IndiaCoalfields, and Metadata. Folder Contents The contents of the folders are as follows: Folder name: BangladeshAnalyticalData Contents: BangladeshAnalyticalData.dbf BangladeshAnalyticalData.prj BangladeshAnalyticalData.sbn BangladeshAnalyticalData.sbx BangladeshAnalyticalData.shp BangladeshAnalyticalData.shp.xml BangladeshAnalyticalData.shx Folder name: BangladeshCoalfields Contents: BangladeshCoalfields.dbf BangladeshCoalfields.prj BangladeshCoalfields.sbn BangladeshCoalfields.sbx BangladeshCoalfields.shp BangladeshCoalfields.shp.xml BangladeshCoalfields.shx Folder name: IndiaAnalyticalData Contents: IndiaAnalyticalData.dbf IndiaAnalyticalData.prj IndiaAnalyticalData.sbn IndiaAnalyticalData.sbx IndiaAnalyticalData.shp IndiaAnalyticalData.shp.xml IndiaAnalyticalData.shx Folder name: IndiaCoalfields Contents: IndiaCoalfields.dbf IndiaCoalfields.prj IndiaCoalfields.sbn IndiaCoalfields.sbx IndiaCoalfields.shp IndiaCoalfields.shp.xml IndiaCoalfields.shx Folder name: Metadata BangladeshAnalyticalData Metadata.htm BangladeshAnalyticalData Metadata.txt BangladeshCoalfields Metadata.htm BangladeshCoalfields Metadata.txt IndiaAnalyticalData Metadata.htm IndiaAnalyticalData Metadata.txt IndiaCoalfields Metadata.htm IndiaCoalfields Metadata.txt Spatial Data Spatial data must first be unzipped using Winzip or another zip utility before it can be used in a GIS project. After unzipping there will be four folders containing spatial data files ("shapefiles") representing India coalfields, India analytical data points, Bangladesh coalfields, and Bangladesh analytical data points. After opening ArcMap the shapefiles can be added to the project by clicking File, Add Data, and browsing to the location of the desired shapefile, selecting and adding the shapefile. These shapefiles have a geographic projection, and therefore should not need to be projected prior to use in any ArcMap project. Metadata Project level metadata is viewable and exportable through ArcCatalog, a text editor, or with a web browser. To view metadata files with a text editor (e.g. Notepad, Wordpad, Word), double click on one of the metadata files with the .txt extension, or drag the file to your text editor's icon. To view the metadata file in a web browser, click on one of the metadata files with the .htm extension, or drag the file to your browser's icon. To view metadata in ArcCatalog, click on any of the four shapefiles in ArcCatalog and then click the Metadata tab.
