Raster data, also known as data grids, stores map data as matrices. Regular data grids require a referencing object, vector, or matrix that describes the sampling and location of the data points. Geolocated data grids explicitly identify the latitude and longitude coordinates of all rows and ...
this activity groups the values of multispectral data into classes (such as vegetation type) and assigns a categorical value. Thematic maps can also result from geoprocessing operations that combine data from various
Raster data is partitioned by Quadbin grid; a type of data known as a Spatial Index. In this format, location is encoded through a short reference ID, enabling highly performant storage of big data. The actual raster data itself is stored as a binary array of Quadbins, each containing ...
Raster data with subdatasets has a data structure that allows the file format to contain multiple datasets in one parent file; this is also known as a multipage raster. Additionally, each of the subdatasets can consist of one band or multiple bands. Hierarchical data format (HDF) and ...

[translate] aIn raster data analysis, the overlay of datasets is accomplished through a process known as "local operation on multiple rasters" or " map algebra ," through a function that combines the values of each raster's matrix . 正在翻译,请等待... [translate] ...
A raster operation, also known as a task or geoprocessing operation, is a web service endpoint designed to work withraster data. Raster operations allow you to run a specific analytical process on a raster dataset likeclassification,change detection,terrain analysis,spatial interpolationand mo...
Temporal resolution refers to the frequency at which images are captured over the same location on the earth's surface, otherwise known as the revisit period, which is a term most often used when referring to satellite sensors. For example, a sensor that captures data once a week has a hi...
data), such as georeferenced rasters or a vector feature class that resides in the desired map coordinate system. The process involves identifying a series of ground control points—known as x,y coordinates—that link locations on the raster dataset with locations in the spatially referenced data...
