Description:
SPLAT! Software
From the SPLAT! page:
SPLAT! is an RF Signal Propagation, Loss, And Terrain analysis tool for the spectrum between 20 MHz and 20 GHz.
Applications of SPLAT! include site engineering, wireless network design, amateur radio communications, frequency coordination, communication system design, and terrestrial analog and digital television and radio broadcasting.
Also, from the SPLAT! manual:
SPLAT! imports topographic data in the form of SPLAT Data Files (SDFs). These files may be generated from a number of information sources. In the United States, SPLAT Data Files can be generated through U.S. Geological Survey Digital Elevation Models (DEMs) using the usgs2sdf utility included with SPLAT!.
Task Description
I plan to use SPLAT! to generate some coverage maps for areas of the lunar surface. To do so, I need lunar topography data either in the SDF form, or in a form that can be converted using the usgs2sdf utility.
See Rover Calculations Link Budget
ULCN2005 datasets [from here] can be converted for SPLAT! However, these DEMs were produced from older data. We are interested in running SPLAT! with newer data from the LRO mission and other more recent missions. Some examples are:
Task Requirements
Given the many available datasets, part of the problem may be in identifying the correct ones to use. However, newer datasets appear to often be provided for GIS applications or for the ISIS tool, both of which have specific formats which need to be converted to the SPLAT! Data Format (SDF) before they can be used.
Therefore, there are two separate requirements for this task, and satisfying either one will complete the task.
- Identify published Digital Elevation Model (DEM) datasets, or alternatively contact the agencies providing the datasets to see if they can be published as DEMs. OR
- Write a software converter to convert the published datatypes into a SPLAT!-friendly format and make it available.
