RASTER FORMAT IN GIS SOFTWARE

Mosaic datasets can contain multiple resolutions of raster data. Handing multiple resolutions of mosaic datasets

It is important to consider limiting the analysis extent or data resolution in your operations. Mosaic datasets can be extremely large (hundreds of thousands of rows and columns of cells), so running any analytical tools on them can consume a lot of system resources and take a lot of execution time. Using mosaic datasets and image services in analysis and geoprocessing.Mosaic datasetsĪny Spatial Analyst tool that supports raster as input can operate on mosaic datasets. Consult the individual tool references for more specific details. The exceptions are certain tools in the Multivariate and Extraction toolsets which do process each of the bands in a multiband input and can create a multiband output. When a multiband raster is used as input, most Spatial Analyst tools operate only on the first band. Following are some topics that discuss these format limitations: Limitations of data formatsĬertain data formats have limits that may be encountered when creating output. The location where these scratch files get created can be controlled with the Scratch workspace environment. After the operation completes and the output has been created, the scratch files are deleted.

When running Spatial Analyst tools that operate on raster or feature data, there may be some situations that cause the software to create intermediate or scratch files in the process of the operation. The feature class can be created in a geodatabase, or if in an output folder, as a shapefile. Output feature dataįor output, the supported feature types are point, multipoint, polyline, and polygon, depending on the particular geoprocessing tool being used. Feature data Input feature dataĪll supported feature classes for ArcGIS of the appropriate type are natively processed by Spatial Analyst tools as input. However, once an output raster has been created, it can easily be converted to another format with the Copy Raster tool. Specifying output raster formats and namesĪrcGIS supports fewer raster formats for output than it does for input, and Spatial Analyst specifically supports fewer output raster formats than ArcGIS does in general.The location and name you specify for the output raster determines the format in which it is created. The supported output raster formats are the following: The benefits of this are reduced processing times as well as reduced disk space consumption.

In general, all the input raster formats supported by ArcGIS are natively processed by Spatial Analyst tools.īeing able to read the supported raster formats directly eliminates any conversion step that might have otherwise created intermediate temporary files when executing operations on certain data formats. Spatial Analyst can operate on raster data that is either file based or in a geodatabase. While many formats are natively supported by Spatial Analyst as input, only certain formats are supported for output. The ArcGIS Spatial Analyst extension accepts as input all relevant raster, feature, and table formats that are supported by ArcGIS.
