Terminology F Georeference: Aligning geographic data to a known coordinate system so it can be viewed, queried, and analyzed with other geographic data. Georeferencing may involve shifting, rotating, scaling, skewing, and in some cases warping or rubber sheeting the data. F Geocode: associating a table of address data with a gis street file to create a point gis layer

Shapefile (.shp) F A vector data storage format for storing the location, shape, and attributes of geographic features. A shapefile is stored in a set of related files (.shp,.dbf,.shx…) and contains one feature class (point, line or polygon.

Geodatabase F relational databases that contain geographic information (stored with the extension.mdb – same as MS Access). F Can contain points, lines, polygons, tables, annotation and rasters F Enables topology: a set of relationships that defines how the features in one or more feature classes share geometry—for example, in an underground network it is important to know which pipes are on top or bottom and if they are connected; census tracts cannot cross each other nor county lines. F Data in a geodatabase must all be in the same coordinate system and share a common geographic area F Must have ArcEditor or ArcInfo license to create and edit
