It is worth some time to do some extras study to see how If the format is recognizable and trivial, a non-programmer can probably write a description for it with our style scheme in under an hour. If you can read and explain everything you see ("here's a longitude, there's a name, this is the altitude in meters, etc."), it's probably pretty easy to add this format. Open a representative file in your favorite text editor such as TextEdit.app or Notepad. You can see which category your request falls into. In rough terms, most of our file formats fall into one of three categories. If you want something done badly enough and can't find volunteers to do it, contract programmers can often get it done. Reasonably sized, developers will implement things for you. Sometimes, if you ask nicely, and your request is Much of the development is done by people solving their own GPSBabel isn't developed by a company it's done by volunteers. Generally, simpla and "obvsious changes can be done and integrated Since our build system makes a snaphot every night, this is rarely a Releae schedules can be harder to predict, but Once that's done, it'll be on board the cargo car awaiting the departureĬar of the next release. Work more like the rest of GPSBabel or to be better strutured internally. Have different skills, resources, and time) will need to integrate thatįeature into the main program, sometimes working together to make something Beyond that, additional programmers (that may See Google Earth's documentation on timelines for more info.As soon as programmer with the skill, resources,Īnd time implements it. You can widen the time slider to show the range of data of interest. Tweak Earth's settings to "view->show time->never" or This means that only the first data point will be displayed. The time slider defaults to the far left position and fully closed. Points that contain time or almost any track data) this will be important If you're using data that has timestamps (e.g. Earth's "time slider" feature controls what timestamped data Google Earth 4.0 and later have a feature that can surprise users of thisįormat. GPSBabel handles simple KML on read fairly well, but if you're dealing with handcrafted KML that uses extensive features that have no analog in other formats like nested folders, ringgeometry, camera angles, and such, don't expect GPSBabel to do well with them on read. In general, GPSBabel's KML writer is relatively strong. Google Earth also uses GPSBabel internally for receiver communicationsĪnd several file format imports and exports. GPSBabel represents internally as tracks) work fine. Simple files with waypoints and paths (which Reading suchįiles with GPSBabel - even if your goal is to write it back out as KML - can often KML files may have tiered "Styles" whichĬan identify sizing info and URLs of associated icons. Ideas of camera views and names and descriptions can have arbitrarilyĬomplicated HTML in them. Read because they don't map well into other programs. There are concepts in KML that GPSBabel can't support very well on KML, the Keyhole Markup Language format, was used by Keyhole and is used by This format has the following options: deficon, lines, points, line_width, line_color, floating, extrude, track, trackdata, trackdirection, units, labels, max_position_points, rotate_colors, prec.
