Requesting a description of what a raw file is

 

Been awhile since I've been here....plus I'm old...LOL. Can someone please tell me what it means when an author describes his file as a raw file?

A file that was done from scratch and once finished, it is saved or converted as needed to work in your device. Garmin example would be csv or gpx. That is my take on a raw file.

Clarify

Can you clarify a bit more as to what you mean? Perhaps supply something of the context? Could you really be meaning “raw data”? Can we rule out “raw” photography files?

Raw file

Thank you Charles, was thinking not finished or un-readable file so appreciate the explanation.

Raw file

Hi John, the example was one author put in the description that it was in a raw format (I believe?) and didn't know if that could be used or read by the GPS. Sorry about being so vague

Probably means not finalized

…for instnace you can create a Excel spreadsheet that includes all the information for a POI file, but it would be called raw if the data was not arranged properly. Or something like latitude might be in a format of degrees, minutes, seconds whereas the device need degrees including the fractional part.

Ask the maintainer of the file just exactly what he means. You might actually get a precise answer as to why he says "Raw".

Or download the file and

Or download the file and look at it yourself.

Raw depends on context, but generally means something along the lines of uncompressed, original quality. A .wav file is an uncompressed audio file meaning lossless. A mp3 is a representation of that wav file, approximating it's data (to the ear at least), but is smaller due to compression. It's considered a lossy format.

In terms of gps, i'd say a gpx would be considered raw, while a gdb would be a binary form of the same data.

Raw File

Thank you all for taking the time and explaining what the author meant. I'm preparing for a trip (tomorrow Set 24th) and I deleted my old downloads for Walmart/Sams Club, Costco, Truck Stops & Diner, drive-in and dives to the latest updated downloads. So I was a bit confused by the one file stating it was in a raw file (?) format but all you folks gave me the explanation and all new downloads work and function well. Thanks again, appreciate all the advice and help.....Jack
