This Spectrum Management (SM) Case Study describes database and software structure and is dedicated to help engineers to use such software and to contact with SM software vendors. 

The main objectives of this  Case Study is to aim users for selecting and  ordering proper Spectrum management software. The Spectrum management automated systems are expensive software packages, usually installed on limited number of PC with regular support fees and with no possibility to be changed by the users. Some of the proposed options appear useless for a part of the users, on a contrary, necessary opportunities are missed. A modular structure of the Spectrum management software and a possibility to select and to change the needed modules will increase the functionality of the Spectrum management tools.

A lot of manual operations were implemented for network coordination. Since October 2001, the ITU-R rapporteur group has examined the material provided to Working Party 4A, and developed the draft specification for software to assist the examination of space filings. Through correspondence, and at one meeting, the group has worked with the BR to define a basic specification for automating the examination of Radio Regulation (RR) Article 5 and has developed databases of the relevant provisions of Radio Regulation Article 5. The ideas and the specifications of these actions are further developed in the current Case Study.

The implementation of computer aided Spectrum Management in many countries (more than 80% of the ITU members) meets the problem with the Digital terrain map (DTM) absence. The software proposed by ITU in the FM Software Catalogue did not use DTM. Some companies offer excellent FM software with DTM at a high cost. To make corrections and upgrading of these DTM would be difficult and time consuming. The digital Geographic Information System (GIS) is one of the key components of computer-based automated spectrum management and spectrum monitoring systems.

The utilization of the global digital elevation model (DEM) resulting from  collaborative efforts made by the staff at the U.S. Geological Survey's EROS Data Center in Sioux Falls, South Dakota is proposed in this document.

The package with 30 sec. resolution is distributed free on Internet or on CD-ROM and can be used for educational purpose. Higher resolution DTM with the same format for different regions are available upon ordering.
