# INTRODUCTION

This General Software User Manual consists of the following sections:

- Introduction explaining how to use this document
- Overview of the CFI libraries, indicating the CFI classes available within each of the CFI software libraries, and the data and control flow between those libraries.
- Installation guide, explaining how to get, install and validate any of the CFI software libraries, as well as listing the software items provided with the delivery of the related CFI.
- Library usage overview, describing how to create a user application
- Detailed description of the error handling functions which are delivered with each CFI. This is described in this document because all CFIs use exactly the same error handling mechanism

The specific Software User Manual of each CFI software library ([EE_COMMON_SUM], [F_H_SUM], [D_H_SUM], [LIB_SUM], [ORBIT_SUM], [POINT_SUM], [VISIB_SUM]) describes in detail the use of each of the CFI functions included within that library, as well as refine the description regarding how to use that library.
In addition to the general and specific SUM for a CFI library, the user must refer to the Mission Conventions Document ([MCD]) for details on the time references and formats, reference frames, parameters and models used in all these software user manuals.

# CFI LIBRARIES OVERVIEW

The Earth Observation Mission CFI Software is a collection of classes and methods performing accurate computations of mission related parameters for Earth Observation missions.
Those classes are delivered in the form of software libraries gathering together the classes and methods that share similar functionalities.
An overview of the complete CFI software collection is presented in next figure.

Earth Observation CFI software libraries

The CFI software libraries are to be seen as several layers, each layer being directly accessible to a user‘s program. Lower layers are more generic classes which are likely to be used by most application software, whereas higher level layers are more specialized classes which are to be used for more specific tasks.
Next shows the software dependencies between the CFI software libraries, where each row between libraries indicates that the higher level library requires the lower level one to operate.

Earth Observation CFI Software libraries dependencies

Furthermore, the high level data flow between those CFI libraries are shown in next figure:

ORBIT, POINTING and VISIBILITY data flow

# CFI LIBRARIES INSTALLATION

This section describes the procedures to get, install and validate the installation of a CFI software library. It also describes the directory structure and available files resulting from a successful installation.
These procedures and structures are the same for each of the available CFI software libraries and so, they will be described in this document for a generic CFI, namely cfi_name.

http://eop-cfi.esa.int (main page)
From there, just follow the links until you reach the Earth Observation CFI page:
http://eop-cfi.esa.int/CFI/ee_cfi_software.html Follow the instructions given on the page and you will be able to save the distribution file(s) on your local disk.

## How to install the Software

The installation procedure details are described in the Release Note that can be found in the ESA EOP System Support Division Web Server:
http://eop-cfi.esa.int (main page)

## Overview of Files and Directory Structure

Upon completion the installation procedure, the following directory structure will be created: (OS: LINUX32_LEGACY, LINUX64_LEGACY, LINUX64, MACIN64, WINDOWS) (LibraryName: FileHandling, DataHandling, Lib, Orbit, Pointing, Visibility)

The following subsections describe the content of the directories.

### Directory: Documents

Documents are delivered as separate packages not contained in the installation package. The following documents are available:

- Mission Conventions Document.
- Software User Manuals.
- Release_Notes.pdf: Release Notes detailing the changes and/or corrections introduced in the new release.

### Directory: Installation directory

This is the directory where the CFI will be installed. The directory has to be created by the user. It contain scripts to compile and run the validation and example programs. The name of the scripts can be:

- validation.sh: script to compile and run the validation programs in LINUX and Mac OS platforms
- example.sh: script to compile and run the example programs in LINUX and Mac OS platforms

or

- validation.bat: script to compile and run the validation programs in Windows platforms
- example.bat: script to compile and run the example programs in Windows platforms

### Directory: lib

This directory contains the CFI dynamic libraries for one computer platform.

### Directory: include

This directory contains the header files of the classes of each library.

### Directory: validation

This directory contains the validation program and associated makefile:

- LibraryValid.java
- makefile files for the different allowed operative systems, i.e. Solaris, Windows 95/98/NT/2000, Linux and MacOS.

Depending on the CFI, input data files used by the validation program may be included. In such a case they can be found in the directory example/data. After running the validation procedure, other files appear.

- LibraryValid.class
- LibraryValid.OS.out (OS stands for the different allowed operative systems)
- other output files depending on the library.

### Directory: example

This directory contains example programs and associated makefiles.

- LibraryExample.java
- makefile files for the different allowed operative systems, i.e. Solaris, Windows 95/98/NT/2000.
- data files used for the validation and example drivers.

Depending on the CFI, example data files to be used with the CFI may be included in a separate data subdirectory.

## Validation Procedure

This procedure should be run to verify the proper installation of the CFI library. Two different procedures can be followed:
A) Run the validation programs for every library:

1. Go to directory validation
2. There you will find the validate script corresponding to your operating system:
   - WINDOWS: validate.bat
   - Rest of operating systems: validate.sh
3. validate script makes all the necessary settings in the environment variables to find the libraries of the installation. Note that native libraries link with another dynamic libraries (see software requirements), that the system must be able to find (they are looked for in LD_LIBRARY_PATH for LINUX and SOLARIS, DYLD_LIBRARY_PATH for MAC systems and PATH for WINDOWS).
4. Run the validate script:
   - For all OS except Windows: ./validate.sh OS
   - For Windows: validate.bat

The validation program is created, executed and a validation status message printed. The message should look like:

Library: ... CFI LIBRARY INSTALLATION = OK

or:

Library: ... CFI LIBRARY INSTALLATION = FAILED !!!

In the latter case, check again your installation, and run the validation program again if necessary. If the message persists, report the problem.
During the execution of the validation program a log file LibraryValid.OS.out (OS stands for the different allowed operative systems) is also created. It can be consulted for a detailed listing of the validation run.
B) Run all the validation programs with the validation script:

1. Go to installation directory (Installation_Directory).

2. Run the validation program using the script validate.xxx (xxx = sh for Linux and Mac Os, xxx= bat for Windows)

   validation programs for all libraries will be created and executed. At the end of the execution, a log file validation_OS_log.txt is created (at the level of Installation_Directory) with the result of the validation for every library.

   ## Examples

   An example is provided to illustrate how the interface with the CFI functions contained in the CFI software library works, and in particular how to handle the returned errors through exceptions.
   The example is called LibraryExample.java. The script used to compile the example is:

   - runExample.bat for WINDOWS
   - runExample.sh for any other operating system

   The examples should be self-explanatory. To use them, use the same procedure as for the validation program.
   In an user application, the same conventions to compile and link as in the example compilation scripts should be followed.
   Note that CFI libraries call native methods in dynamic libraries, so proper setting of the environment must be performed at run-time. This means:

   - SOLARIS/Linux: adding to the LD_LIBRARY_PATH environment variable the locations of all dynamic libraries needed.
   - MacOS: adding to the DYLD_LIBRARY_PATH environment variable the locations of all dynamic libraries needed.
   - Windows 95/98/NT/2000: adding to the PATH environment variable the locations of all dynamic libraries needed.
   - All systems: adding the full path of jar files to CLASSPATH environment variable, not only the directory where they are, but its complete path.

   It is advised to consult your manuals for proper usage of dynamic linking libraries.
   Alternatively all the example programs can be compiled and executed using a single script:

   1. Go to installation directory (Installation_Directory).
   2. Run the example program using the script example.xxx (xxx = sh for Linux and Mac Os, xxx= bat for Windows)

   The example programs for all libraries will be created and executed. At the end of the execution, a log file example_OS_log.txt is created (at the level of Installation_Directory) with the result of the example execution for every library.

   ## Problems Reporting

   For any problems or questions, please send an e-mail to: cfi@jw.estec.esa.nl

   # CFI LIBRARIES USAGE

   ## Using CFI’s in an user application

   To use CFIs in an application, the user must:

   - import the CFI classes used in the application, taking into account that all the classes are part of the EECFI package
   - Set the CLASSPATH environment variable properly, so jar files where the classes used are defined are included in the path
   - Make sure that system can find native dynamic libraries used by Java classes

   ## General enumerations

   It is possible to use enumeration values rather than integer values for some of the input arguments of the routines, as shown in the table below. The XXCFI prefix is generic, that is, it must be replaced by the corresponding library prefix, e. g., XLCFI for Lib, XOCFI for Orbit, and so on.

   Input/Output | Description | Enumeration value | long
   --- | --- | --- | ---
   Satellite ID | Default Satellite | XXCFI_SAT_DEFAULT | 0
   Default Satellite 1 | XXCFI_SAT_DEFAULT1 | 1
   Default Satellite 2 | XXCFI_SAT_DEFAULT2 | 2
   Default Satellite 3 | XXCFI_SAT_DEFAULT3 | 3
   Default Satellite 4 | XXCFI_SAT_DEFAULT4 | 4
   Default Satellite 5 | XXCFI_SAT_DEFAULT5 | 5
   Default Satellite 6 | XXCFI_SAT_DEFAULT6 | 6
   Default Satellite 7 | XXCFI_SAT_DEFAULT7 | 7
   Default Satellite 8 | XXCFI_SAT_DEFAULT8 | 8

   Terrasar | XXCFI_SAT_TERRASAR | 81
   EarthCARE | XXCFI_SAT_EARTHCARE | 91
   Swarm-A | XXCFI_SAT_SWARM_A | 101
   Swarm-B | XXCFI_SAT_SWARM_B | 102
   Swarm-C | XXCFI_SAT_SWARM_C | 103
   Sentinel-1A | XXCFI_SAT_SENTINEL_1A | 110
   Sentinel-1B | XXCFI_SAT_SENTINEL_1B | 111
   Sentinel-2 | XXCFI_SAT_SENTINEL_2 | 112
   Sentinel-3 | XXCFI_SAT_SENTINEL_3 | 113
   Seosat | XXCFI_SAT_SEOSAT | 120
   Generic satellite | XXCFI_SAT_GENERIC | 200
   Time reference | Undefined time reference | XXCFI_TIME_UNDEF | -1
   TAI time reference | XXCFI_TIME_TAI | 0
   UTC time reference | XXCFI_TIME_UTC | 1
   UT1 time reference | XXCFI_TIME_UT1 | 2
   GPS time reference | XXCFI_TIME_GPS | 3
   Time window initialisation | Initialisation from file | XXCFI_SEL_FILE | 0
   Initialisation from time | XXCFI_SEL_TIME | 1
   Initialisation from absolute orbit number | XXCFI_SEL_ORBIT | 2
   Default initialisation | XXCFI_SEL_DEFAULT | 3

   available it is strongly recommended to use enumeration values rather than integer values.

   # ERROR HANDLING

   Error handling in CFI classes is made through exceptions. Every time a method of a CFI class produces an error, an exception of type CfiError (defined in [EE_COMMON_SUM] library documentation) is thrown. To handle exceptions, user code must be placed within a try-catch block. Example follows:

       try
       {
       CfiClass cfiClass; // Object creation
       ... // Operations
       }
       catch( CfiError cfiError )
       {
       // Handle exception
       }

   CfiError class has methods to print error messages and get error codes:

   - getMsg: return the messages describing the error.
   - getCodes: return the error codes, and the corresponding library and function codes. This last option is only relevant for users comming from C libraries, since the errors codes returned are the ones of the C-libraries.

   By default, when a warning is produced in a method of a CFI class, it is not handled. To handle the warnings, every CFI class has two methods (inherited from CfiClass):

   - setWarning: it sets the warning flag to true, so every warning produced in a method of the class will be thrown as an exception of type CfiError.
   - resetWarning:it sets the warning flag to false, so nothing will be done when a warning is produced.

   For more details, refer to the class documentation.

   # KNOWN PROBLEMS
