Purpose
Geocoded images and Digital Elevation Models may be transformed from one cartographic reference system to another; the pixel spatial resolution can be modified as well.
Technical Note
Complex data type is not admitted.
If the input "Reference file" is entered, its cartographic projection and grid size are used for the file transformation. If the input "Reference file" is not used, the output cartographic projection and grid size must be specified.
Input Files
Input Reference File
Input file to be used as transformation reference. The output transformed data will have same corner points, same cartographic system and same grid size of the reference file.
Input file list
Input file name(s) of the data to be transformed. This file is mandatory.
DEM/Cartographic System
Output Projection
In case the Reference file is not used, the following parameters are compulsory to define the Cartographic System:
State
Definition of the country or general projection systems.
Projection
Definition of the projection system of the selected State. In case that a general projection system is selected in State, the Projection is automatically set.
Ellipsoid
Definition of the ellipsoid. This is chosen according to the selected State and Projection.
Hemisphere
Definition of the hemisphere. This is chosen according to the selected State and Projection.
Zone
Definition of the zone. This is chosen according to the selected State and Projection.
Datum Shift Parameters
Definition of the datum shift parameters. These are chosen according to the selected State and Projection.
Cartographic Parameters
The reference parameters for some projection systems (e.g. Stereographic, Polar Stereographic, Gnomonic, Mercator, Miller, Albers, etc.) can be set.
Parameters - Principal Parameters
Type
One of the following file types can be selected for the cartographic transformation:
Image
All raster data except Digital Elevation Model.
DEM
Digital Elevation Model. This should be referred to the ellipsoid.
Activate Coordinates Selection
By setting this flag it is possible to specify a spatial region for the output file generation (co-ordinates are referred to the output cartographic reference system).
| - | West |
The Westernmost cartographic co-ordinate.
| - | East |
The Easternmost cartographic co-ordinate.
| - | North |
The Northernmost cartographic co-ordinate.
| - | South |
The Southernmost cartographic co-ordinate.
X dimension
The grid size of the output data in Easting (X) must be defined only if the Reference file is not used; the default unit of measure is meters.
Note that - for the Geographic projection - if values higher than 0.2 are entered they will be considered as metric units and then automatically, and roughly, converted from meters to degrees; if values lower than 0.2 are entered they will be considered as degree and used as such without any conversion.
X dimension
The grid size of the output data in Northing (Y) must be defined only if the Reference file is not used; the default unit of measure is meters.
Note that - for the Geographic projection - if values higher than 0.2 are entered they will be considered as metric units and then automatically, and roughly, converted from meters to degrees; if values lower than 0.2 are entered they will be considered as degree and used as such without any conversion.
Parameters - Global
It brings to the general section of the Preferences parameters. Any modified value will be used and stored for further processing sessions.
Parameters - Other Parameters
It brings to the general section of the Preferences parameters. Any modified value will be used and stored for further processing sessions.
Output Files
Output file list
Output file name(s) of the transformed data. This file is mandatory.
_rsp
Transformed data and associated header files (.sml, .hdr).
_rsp_par.sml
Xml file containing temporary processing parameters.
Details specific to the Units of Measure and Nomenclature of the output products can be found in the Data Format section.
