Esri, NASA collaborate to advance Cloud access to imagery

US: Esri and NASA are coming together to improve access to imagery and raster data stored in the cloud using a combination of two technologies, Meta Raster Format (MRF) and Limited Error Raster Compression (LERC). MRF is an Open raster format originally designed at the NASA Jet Propulsion Lab (JPL) to optimize web access to rasters. LERC is a highly efficient algorithm that provides fast lossless and controlled lossy compression of image and raster data. LERC is especially suitable for geospatial applications. Esri was recently awarded a US Patent for LERC, and is making the patented LERC technology freely available to the geospatial and earth sciences community. “We’ve been using MRF to create and distribute imagery for a number of years, but we are only now starting to explore browser access to these datasets. Our collaboration with Esri and the release of Esri’s patent on LERC ensures that more people can enjoy efficient, accurate transmission of imagery and data over the web,” said Kevin Murphy, Program Executive, NASA Earth Science Data Systems.
