Purpose

 

This tool allows importing external geoids to SARscape in order to make them available for processing where other geoids than the ones provided (EGM96 and EGM2008) are needed.

 

Technical Note

 

In any SARscape processing where the DEM input is foreseen, ellipsoidal heights have to be preferred in order to avoid errors related to the use of geoids, which differ depending on the specific geographic location; vice versa the adoption of ellipsoidal heights ensure consistency with most of the current satellite systems, whose measurements and parameters are referred to earth center.

 

This tool provides the possibility to import and manage different geoids in case there is a need to use a geoid different than the ones already provided with SARscape (EGM96 and EGM 2008).

 

Input File

 

Input file

Geoid that wants to be insert in the Geoid List.

 

Geoid name

This name will be used to save the geoid in the Input File in the Geoid List.

 

Parameters - Principal Parameters

 

Geoid Type

SARscape Format geoid

Use this input type to import a geoid in SARscape format (with .sml header). Is has to be in GEO-GLOBAL cartographic system an values have to be expressed in meters [m].

 

Japan ASCII

Use this input type to import the Japan geoid in ASCII format.

 

TIFF

Use this input type to import a geoid in TIFF format. It has to be in GEO-GLOBAL cartographic system an values have to be expressed in meters [m]. Note: Tiled tiff are not supported.

 

Geoid List

This list contains all the User imported Geoids. This field has to be leaven empty if the "Import" action is selected below.
