What is a geodatabase file?
A file geodatabase is a collection of files in a folder on disk that can store, query, and manage spatial and nonspatial data, Create a file geodatabase in a project folder or using the Create File Geodatabase geoprocessing tool.
What do I do with GDB files?
A GDB file is a database file created by MapSource, a GPS route editing and trip-planning application. It contains waypoints, routes, and tracks that can be transferred to a Garmin navigation device. GDB files are similar to the universally transferrable . GPX files.
How does a geodatabase work?
A geodatabase is a database designed to store, query, and manipulate geographic information and spatial data. Within a spatial database, spatial data is treated as any other data type. Vector data can be stored as point, line or polygon data types, and may have an associated spatial reference system.
Which software can open GDB file?

What is the purpose of an attribute table?
The Attribute Table function allows you to define an attribute table to symbolize a single-band mosaic dataset or raster dataset. This is useful when you want to present imagery that has undergone a classification to land use, such as forest land, wetland, crop land, and urban.
What is the main purpose of a geodatabase?
The geodatabase is the native data structure for ArcGIS and is the primary data format used for editing and data management. While ArcGIS works with geographic information in numerous geographic information system (GIS) file formats, it is designed to work with and leverage the capabilities of the geodatabase.
Why do we use geodatabase?
Whether you are working with large or small datasets, file geodatabases optimized for use in ArcGIS are ideal for storing and managing geospatial data. File geodatabases offer structural, performance, and data management advantages over personal geodatabases and shapefiles.
What are the advantages of file geodatabases?
The file geodatabase uses an efficient data structure that is optimized for performance and storage.
Is file geodatabase really faster than the shapefile?
Running ‘Compact’ on the geodatabase greatly improves its performance; however, in an unsymbolized draw, redrawing the shapefile may still be faster. When using an attribute value for a symbolized draw, file geodatabases usually draw faster than shapefiles.
How to recover file geodatabase works?
The Recover File Geodatabase tool works by opening each of the tables in the damaged file geodatabase directory, reading the file’s header, and creating a copy of the table in a new file geodatabase. If the system schema tables are still present, then table names will be preserved; if not, names will be assigned.
What is the difference between a shapefile and a geodatabase?
Answer Wiki. Well, basically, a geodatabase can be anything that allows you to store spatial data and perform spatial query on the data containing it. A shape file is a file based format for storing spatial data. So a shapefile is actually also a geodatabase.
