Where can one found out what the most pervasive GIS formats are?
For example, from the GIS file formats Wikipedia page, there 4 broad categories, each with many popular formats.
- Raster formats (13 formats listed)
- Vector formats (19)
- Grid formats (4)
- Other formats (5)
This is a dizzying array of alternatives, each with their own reasons for existence.
In terms of general formats though, what are the most pervasive ones in use?
Edit: By pervasive, I'm looking for say the top 3 formats that would be encountered if a company that used GIS data was randomly selected out of all companies using GIS data
