ETSI Deliverable
Subject Digital terrain data in SEAMCAT
Related WI
Scope To include the possibility to load digital terrain data to be used in combination with some propagation models within SEAMCAT
Deliverable Other
Responsible group WG SE - STG
Start date 29-05-2019
Target date 31-01-2021
Public Consultation
Regular Work Item False
Comments Several propagation models within SEAMCAT require terrain data to fully comply with the specifications for the computation of the transmission loss. These include: 
• Rec. ITU-R P.452
• Rec. ITU-R P.1546 
• Rec. ITU-R P.1812 (this propagation model still needs to be implemented)
• Rec. ITU-R P.2001
• Longley Rice
STG already discussed the possibility of including digital terrain data in SEAMCAT on several occasions. The latest discussions took place in 2017 and the status of these discussions is reflected in the minutes of the 57th meeting of STG in document STG(17)125, section 5.5.
It should be noted that SEAMCAT is not intended for planning purposes. In that sense, the implementation of digital terrain data will include any necessary caveats to reflect that fact.
