Precisely Multi-Resolution Raster (MRR_NATIVE) Reader

The Multi-Resolution Raster (MRR) provides FME with access to data in the MRR format.

FME uses GDAL libraries and drivers for some raster and vector formats. For the GDAL MRR format, see Precisely Multi-Resolution Raster (MRR) (GDAL) Reader.

Overview

The Multi-Resolution Raster (MRR) format was originally developed as a unifying format, intended to encompass all types of raster data, such as image, classified, discrete, and continuous. Some key benefits of the MRR format:

  • Provides industry-standard compression techniques and predictive encoding techniques to minimize storage requirements and provide efficient data access to extremely large raster/grid datasets.
  • Stores numeric gridded data, imagery and classified (thematic) data.
  • Allows sparse data to be easily accessed and updated, without the need to store values for regions that do not contain data.

Reader Overview

FME considers a single MRR file to be a dataset.

FME Raster Features

FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. The topics below describe how FME processes raster data.
