Georeferencing

To be able to view each tile in correct geographic relation to the National Grid and to each other, the tiles must be georeferenced. GIS typically provide georeferencing as part of their functionality, but for each set of tiles it is necessary to provide the information on how the tiles should be ordered. MiniScale TIFF tiles are in COG (Cloud Optimised GeoTIFF) format, which enables georeferencing information to be embedded within a TIFF file itself.

The Adobe Illustrator file is georeferenced using Avenza MapPublisher. This plugin provides GIS tools for Illustrator and unlocks additional attributes embedded in the MiniScale vector file. It is not a requirement for using the vector file for graphic output, but it does open up new ways of using MiniScale for those that do have the plugin.
