Key Terminology
o A project is a file, with the extension .aprx, that contains one or more maps and related items.
o A file geodatabase is a folder, with the extension .gdb, that stores one or more feature classes, rasters, and other related files. Although there are many other file formats for storing spatial data, the file geodatabase is a preferred ESRI format.
‒ Note: A project does not store spatial data used to make maps but instead stores connections to spatial data, such as a file geodatabase, that is stored elsewhere on your computer, ArcGIS Online, or other locations. When you create a new project in ArcGIS Pro, the geodatabase is created automatically.
o A feature class is composed of vector data and is the basic building block of GIS for storing features that can be graphically displayed on a map. A feature class contains a collection of features (points, lines, or polygons) that share the same geometry type and attributes.
o A raster dataset (or raster) is the other major type of spatial data for mapping. Quite often, a raster is a stored image made up of pixels.
