What is a mosaic dataset in ArcGIS?

Mosaic datasets are used to manage, display, serve, and share raster data. … A mosaic dataset consists of many parts: A catalog that provides the source of the pixels and footprints of the rasters. A feature class that defines the boundary. A set of mosaicking rules that are used to dynamically mosaic the rasters.

What is mosaic data set?

A mosaic dataset allows you to store, manage, view, and query small to vast collections of raster and image data. It is a data model within the geodatabase used to manage a collection of raster datasets (images) stored as a catalog and viewed as a mosaicked image.

What are the three types of raster data?

There are three types of raster data that can be stored in a geodatabase: raster datasets, raster catalogs, and raster as attributes. Raster datasets are single images that are stored in the database.

What is a mosaic raster?

A mosaic is a combination or merge of two or more images. In ArcGIS, you can create a single raster dataset from multiple raster datasets by mosaicking them together. Alternatively, you can create a mosaic dataset and create a virtual mosaic from a collection of raster datasets.

Why do we mosaic images?

Mosaics are used to create a continuous image surface across large areas. For example, among other scenarios, you can use mosaics to handle coverage of very high-resolution image files for an entire continent. Or you can manage an entire historical map series for a nation for every year and every map scale.

What is a mosaic map?

A mosaic map is a map made up of different images which are displayed depending on availability and zoom level. The mosaic map can have one or more overlapping layers, so, if you zoom in or zoom out, one or another layer will be shown. For example, if you zoom out, low quality layers will be displayed.

What are the three types of vector data?

Vector data is split into three types: point, line (or arc), and polygon data.

What is a raster dataset?

A raster dataset is any valid raster format organized into one or more bands. Each band consists of an array of pixels (cells), and each pixel has a value. A raster dataset has at least one band. ArcGIS supports more than 70 different file formats for raster dataset, including TIFF, JPEG 2000, Esri Grid, and MrSid.

What are the types of geospatial data?

There are two primary forms of geospatial data: vector data and raster data.
