I'm trying to open data downloaded from NASA's Earthdata site in ArcGIS 10.4.1. Specifically I'm trying to open "GLAS/ICESat L2 Global Land Surface Altimetry Data (HDF5) V034" (Image below, highlighted in blue, can be found by searching 'Iran Glas').
I have the data downloaded, there are multiple .H5 files which I've tried adding to an open ArcGIS .MXD by using the 'Add Data' tool. Once the files are open in the 'Add Data' wizard, there are even more files to chose from, most of these I'm not interested in. It is difficult/near impossible for me to figure out which files are actually important for importing.
I'd like to know if there is an easy way to filter the data so I can extract only elevation data and then, produce a DEM from the extracted data. I've tried opening several files that prompt to produce pyramids for them - this gives me some hope that the data I want is in specific files. However, it is taking an extremely long time for them to open and build on my machine (too long considering how many files there are to open).
I've started looking at converting the .H5 files to .LAS files, mainly prompted by following ESRI's advice (here: http://www.esri.com/esri-news/arcuser/summer-2013/5-ways-to-use-lidar-more-efficiently).
Would this significantly reduce processing time?
I have a reasonable idea of what I want but need advice on the process and whether this is feasible.
