on-the-fly reprojection

On-the-fly reprojection is a process that takes data stored in latitude and longitude format (unprojected data) and transforms its visual representation to match other projectedProjection refers to a projected coordinate system based on a map projection such as transverse Mercator, Albers equal area, or Robinson, all of which project maps of the earth's spherical surface onto a 2D Cartesian coordinate plane.Learn more datasets. For example, as data is added to a map with a different spatial referenceA spatial reference is a set of parameters, typically defined by a WKID, that define the coordinate system and spatial properties for geographic data. Applications use a spatial reference to correctly display the position of geographic data in a map or scene.Learn more, on-the-fly reprojection performs a temporary data transformation to the map's spatial reference.
