digital map library
GIS
A series of directories and subdirectories designed to uniformly organize a collection of spatial data. Map libraries organize geographic data spatially as a set of tiles and thematically as a set of layers. Volusia County's digital map library is divided into large scale and small scale subdirectories containing several hundred tiles comprising 90 layers of information.
