A user want to use the LP NS special data products for hydrogen abundance at ~15 km/pixel for his research. He want to import it into ArcGIS Pro and run a tool to show only data point with hydrogen signatures > 100ppm since water-ice should be present close to the surface. The link to the archived LPNS data: https://pds-geosciences.wustl.edu/missions/lunarp/reduced_special.html Below is the steps to access the data and do the conversion from an ASCII to a Geotiff in ArcGIS 1) Choose the data. The radius of the Moon is about 1737 km, which means the Moon scale is about 30 km/deg at the equator. scale = radius *2 *pi / 360 So for gridded data at 1/2 deg corresponds to about 15 km/pix. 2) Convert from an ASCII to a Geotiff in ArcGIS Pro. ‘ASCII To Raster’ is a deprecated tool in the ArcGIS Pro. The Copy Raster tool can be used in the ArcGIS Pro to convert an ASCII file representing raster data to a raster dataset. First prepare an ASCII file for ArcGIS Pro according to the information in https://pro.arcgis.com/en/pro-app/latest/tool-reference/conversion/ascii-to-raster.htm. See attached example ASCII files. Suggest to change the file extension to *.asc to get better performance in ArcGIS Pro. Other extensions might have problem in the conversion. Then run the Copy Raster tool to make the conversion. hydrogenhd_mod.txt ironhd_mod.txt
The PDS Geosciences Node released the MakeLabels tool this July. The program can be used to generate PDS4 labels using a label template and one or two Excel spreadsheets. It replaces placeholders in the template with values from the spreadsheets. In fact it can be used to output any type of ASCII file. More information about the program and it's downloadable file can be found on the PDS Geosciences Node website. http://pds-geosciences.wustl.edu/tools/makelabels.html
