When to store raster data in a geodatabase?
Store raster data in the geodatabase when you want to manage rasters, add behavior, and control the schema; when you want to manage a well-defined set of raster datasets as part of your DBMS; and when you require a single architecture for managing all your content. There are three main types of geodatabases: enterprise, personal, and file.
Which is the best way to store image and raster data?
There are three methods to store image and raster data: as files in a file system, within a geodatabase, or managed from within the geodatabase but stored in a file system. This decision also involves determining whether to store all the data in a single dataset or in a catalog of potentially many datasets.
How are raster datasets stored in ArcGIS Desktop?
ArcGIS Desktop supports more than 70 different file formats for raster datasets, including TIFF, JPEG 2000, Esri Grid, and MrSid. A mosaic dataset is a collection of raster datasets (images) stored as a catalog and viewed or accessed as a single mosaicked image or individual images (rasters).
How are raster data and metadata stored and managed?
Individual rasters and metadata comprise mosaic datasets. The data in a mosaic dataset does not have to be adjoining or overlapping but can exist as unconnected, discontinuous datasets.
How are raster datasets stored and managed?
Most imagery and raster data (such as an ortho photo or DEM) is provided as a raster dataset. The term raster dataset refers to any raster data model that is stored on disk or in a geodatabase. It’s the most basic raster data storage model in which the others are built upon—mosaic datasets manage raster datasets.
How is image and raster data stored in ArcGIS?
These datasets, and collections of them, are often very large, so having good management capabilities is critical and ArcGIS is designed to do this. There are three methods to store image and raster data: as files in a file system, within a geodatabase, or managed from within the geodatabase but stored in a file system.
How is raster data stored in a file system?
If you’re choosing to store the data in a file system, you’re choosing to store raster datasets, whereas a geodatabase can store either raster datasets or mosaic datasets.
Is there a limit to the size of a raster table?
2 gigabytes (GB) per geodatabase (This is a table size limit, not a limit on the raster dataset size.)
