MID— MapInfo interchange format (always paired with MIF)
MIF— MapInfo interchange format (always pared with MID)
SHP—A vector data storage format for storing the location, shape, and attributes of geographic features. A
shape file is stored in a set of related files and contains one feature class. Shapefiles can be used to
represent lines, points, or polygons. Often times you will see shape files as field boundaries, sample
points, yield points, elevation, and in tile planning. Shapefiles have at a minimum of three files associated with them to make them functional. These are a SHP, SHX, and DBF. The SHP file contains the
primary geographic reference data in the file. SHX file is the index portion of the file. DBF is the database file. The shapefiles attributes are stored in database format and have a columnar structure for
each attribute.
CSV— Coma Separated Value files can be used as many things, similar to and Excel file. If the CSV file contains Latitude and Longitude columns it can be used as a Points—Vector file in GK desktop software.

JP2— Compressed images with the metadata with XML embedded data. Geo-referenced images can be
opened and displayed correctly on the earth’s surface.
JPEG— Joint Photographic Experts Group—Common image compression method. Compression can be adjusted to select between size and quality of the image. Some of the original image quality is usually
lost in the compression and cannot be restored. JPEG images can also support millions of different
colors.
BMP—Bitmap Image File—Raster image files that can be edited, saved, geo-referenced, and used within the
software. Often times they work well because they are compatible with other software packages and
contain a higher resolution than a JPEG.
TIFF— Tag Image File Format— A common format for exchanging raster graphics images between application programs, including those used for scanner images. TIFF files can be composed of multiple of
