Raster

See Technical Analysis for details on what a Raster File is

To create a Shape File, go to Engage -> Raster -> New Raster

  • Raster: The name to call the Raster File

  • Raster File. Attach a .tiff file

  • Datatype. Whether the pixel values are discrete or continuous

  • Legend. This is a link to a Legend record which defines how to interprete values of pixels. See Legend

  • Nodata value. The value of pixels that will be considered as having no data. NoData means that there is not enough information is known about a pixel cell location to assign it a value. Nodata represents missing or invalid data in a raster grid. Leave this field blank to keep the internal raster band nodata values. If a nodata value is specified here, it will be used for all bands of this raster

  • SRID. Every geometric shape has a spatial reference system associated with it, and each such reference system has a Spatial Reference System ID (SRID). The SRID is used to tell which spatial reference system will be used to interpret each spatial object. A spatial reference identifier (SRID) is a unique identifier associated with a specific coordinate system, tolerance, and resolution.

  • Resolution- Resolution in the spatial domain refers to the size of the smallest measurement unit observed or recorded for an object, such as pixels in a remote sensing image or line segments used to record a curve.
