dear Readers,
using Optimize Rasters function from ESRI, LiDAR img files were converted to LiDAR LERC/MRF format. our objective was to test, adopt, and streamline the use of LERC/MRF files to take advantage of the inherent benefits of using LERC/MRF files over traditional img files (to begin with LiDAR and then adopt the methods for other formats).
1. Using default settings of Img --> LERC conversion options for elevation/LiDAR we had generated MRF files for the desired areas. we found 26 to 27% savings in disk space - 10 TB to 7.2..
2. Original image files were used to build a raster catalog as a first step towards to publish it. to start with we had used a single LiDAR collection folder (all collections were arranged by the month and year) - Mar2013 to built a raster catalog. A 600+ GB LiDAR of imagery when added to a catalog was only 60+ GB.
Issue at hand:
Q1. How to share LERC/MRF files as a service from an ArcGIS server primarily as a background?
Q2. Downloading LiDAR IMG or LERC files might secondary objective from these services.
is Any step by step guide to 'publish' MRF data available?
thanks and regards
Ravi.
To add more information - when we created a LERC/MRF files based raster catalog, the size of the generated catalog was larger than the MRF files for Mar2013 folder. For a similar situation of the img LiDAR files, the catalog was only 10% disk size of the imagery files. regards.
