What is a LOC file?

LOC files mostly belong to EasyGPS by TopoGrafix. The LOC file extension is extensively used by applications which are involved in the usage of location data like EasyGPS, an application used for easy and quick uploading and downloading of waypoints or some GPS mapping programs. The peculiar feature of the LOC file format is the storage of waypoints.

  • Main Usage: The files with LOC format used by EasyGPS may store places of interest, favourite locations, saved or recent locations etc. These files are usually saved in XML format. These files are primarily used to store a set of locations with their view directions and can also be used to represent the position and orientation of a camera in the real or virtual world. It is a simple yet customisable format that allows the environment to control the parameters for user convenience.
  • Content Structure in LOC files:
  • The LOC are store in the following format:
    <locations-file file-format-version="1.0">
    <div style="margin-left: 2em"><location> <div style="margin-left: 2em"> <name> Name </Name> <point1> X,Y,Z</point1> <point2> X,Y,Z</point2> </div></location> ...</div></locations-file>

<div style="margin-left: 2em"> Here, Name is a string used to identify the locations. </div> <div style="margin-left: 2em"> X and Y are the latitude and longitude coordinates. Z is the elevation of each point (in metres). </div> <div style="margin-left: 2em"> <Point1> is the starting location and <point2> is the destination. And the vector from <point1> to <point2> is the view direction. </div>

How do you open LOC files?

LOC file format:

Every file has a defined file format, i.e. how the data is arranged in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the LOC files comes to the following conclusion:
