ESRI Shapefile

Geographical data file format supported by Environmental Systems Research Institute, Inc. (ESRI) software. ESRI Shapefiles are composite data structures consisting of several independent data files. The two files that NADCON works with are:

    • The main file.
    • An index to the main file.

    Note: NADCON will only create a conversion for the main file and the index file. If copies of the other files/file types are needed in order to complete the composite data structure, the user will have to make copies of the existing files and manually rename the files to match the newly converted main file and index file.

    Additional Note: NADCON will not convert a geographic data point if the coordinate is located in the database (.dbf) file.
