The behavior of a line representing a road is the same as the behavior of a line representing a stream.Geographic Feature Data Formats•Shapefile – introduced with ArcView–Also georelational data model – nontopological vector data format.–Very prolific format – much GIS data in Shapefile format.–Simpler than coverages than because they do not store topological associations among different features and feature classes.–Limited analysis capabilities due to lack of topology•Geodatabase – introduced in ArcInfo 8.–Object-oriented model – can characterize features more naturally by defining object types, topological, spatial and general relationships, and interactions.–Geodatabase features can be stored in a single database.–Create custom features in addition to points, lines, polygons–Brings physical model closer to logical model.Supported Data Types•ArcInfo 8 supports four representations of geographic data.–Vector data for representing features.–Raster data for images, grids, and surfaces.–Triangulated irregular networks (TINS) for surfaces.–Tabular data.•Locators and addresses for finding a geographic position from an address.•Locators apply national postal conventions to convert an address to a position.–Note: in AI8, geodatabases do NOT store TINS. They must be kept in coverage workspaces.Three Ways to Create a Geodatabase•Create from scratch.–Use tools in ArcCatalog to create schema for feature datasets, tables, geometric networks, etc.•Migrate existing data.–Can convert by importing shapefiles, coverages, INFO tables, dbase tables, ArcStorm, Map LIBRARIAN, and ArcSDE layers.–Both spatial and non-spatial object component is translated.•Use CASE (Computer Aided Software Engineering) tools.–Can use CASE tools to create new custom objects and generate a geodatabase schema from UML (Unified Modeling Language).Single-user Geodatabase•Personal Geodatabase.–Implemented as a Microsoft Access database (*.mdb file) by using MS jet engine which is installed with AI8. MS access is not needed.–Can be placed on local or network drives.–Generally used for personal or small work-group use.–Can handle small to moderately sized datasets.–Personal
