Loading an ASTER GDEM (Global Digital Elevation Model) tif file in OpenJUMP could be difficult as OpenJUMP correctly decodes the geographic position of the file (which is automatically saved in a .tfw file in the same folder of the TIF) but it doesn't decode file raster data.
The file is displayed into the layer tree of OpenJUMP but not in the view.

In order to correctly load these files in OpenJUMP they should be transformed using an external software.
This procedure shows how to transform an ASTER GDEM file using ImageJ (https://imagej.nih.gov/ij/) with Bioformat plugin (https://imagej.net/Bio-Formats).

To simplify the process, I recommand to download Fiji (https://imagej.net/Fiji/Downloads), a binding of ImageJ with already embedded all the plugins we need (and more). Fiji is available for Windows, Linux and MacOSX.

* Load the original aster.tif file into OpenJUMP. Even if the file is not displayed in the view, OpenJUMP decodes its own
geographical location that will save, in the same folder as the original file, as a file aster.tfw.

* Start Fiji and load the aster.tif file using 'Bioformat' plugin ('''Plugin>Bio-Format>Bio-Format importer''')

* From the Fiji toolbar type on '''Image>Type'''. The uploaded file is indicated as 16-bit. Click on 32-bit

* From Fiji toolbar type on '''File>Save as>TIF''' and save back the file as aster.tif

* On OpenJUMP remove the file aster.tif from the layer tree (click on the file and then right click>remove selected file

* Reopen again the file aster.tif on OpenJUMP

How to translate OpenJUMP into another language

== '''The steps on how to translate OpenJUMP''' ==

This in an ''example for'' translation into ''Brazilian Portuguese''.

;NOTE
:The steps below show the translation on the operating system windows. The steps however are pretty much generally the same for every operating system.

;ATTENTION
:It's crucial that you use the latest snapshot. '''Only snapshots''' are packaged with the language files exposed in the ''/language'' folder.

=== '''Translation process''' ===
# download
#* the most recent development snapshot from the [[Downloading OpenJUMP#Snapshots|snapshot repository]]
# extract
#* it contains a folder named like 'OpenJUMP-DATE-rREV-CORE' (called '''OJfolder''' in the further steps)
#* unpack it to a path of your choice, e.g. to '<tt>C:\</tt>' should result in a folder structure like
#: <tt>C:\OJfolder\bin\
#: C:\OJfolder\lib\
#: C:\OJfolder\licenses\
#: C:\OJfolder\readme.txt</tt>
# set the language
#; SKIP
#: if your operating system is configured to use the language you want to translate OJ to you can skip this step (e.g. your Windows is portuguese and you want to edit OJ's portuguese translation)
#* edit the start script for your platform
#* locate the following lines in the file '''OJfolder\bin\oj_windows.bat''', a similar line exists in '''oj_linux.sh''' for MacOS and Unix os's
#: <pre> rem --- uncomment and change your language/country here to overwrite OS locale setting ---</pre>
#: <pre> rem set JAVA_OPTS=%JAVA_OPTS% -Duser.language=de -Duser.country=DE</pre>
#* uncomment the line
#* add your language and optionally country code
#: <pre> set JAVA_OPTS=%JAVA_OPTS% -Duser.language=pt -Duser.country=BR </pre>
# extract the language files
#; SKIP
#: if using a current snapshots as they distribute the ''language/'' folder already as described below. Be aware that this is not the case for stable releases, but they are not suggested for translation work anyway because they are probably missing changes of the development tree.
#* extract from 'OJfolder\lib\openjump-core-*.jar' (where * are nightly built specific name) only the folder '''language''' into 'OJfolder' resulting in a folder structure like
#: <tt>C:\OJfolder\bin\
#: C:\OJfolder\'''language'''\
#: C:\OJfolder\lib\
#: C:\OJfolder\licenses\
#: C:\OJfolder\readme.txt</tt>
#:'''NOTE''' that OJfolder/'''language'''/ contains lots of ''jump_<languagecode>_<countrycode>.properties'' files
# look in '''language''' folder for a file called "jump_pt_BR.properties" (or the language you want to add/edit). If it does not exist see [[#On new translations]] and come back here thereafter.
# open the file with your favorite editor and translate the strings
#: '''HINT''' if it appears like one line of text try an editor that supports unix line breaks e.g. wordpad
# you will see that on left side is an identifier string while on the right side of the "=" (equal sign) is the translated text
#: '''HINT''' new strings have a date line just before like [sstein 7 march 2007]
# when you are finished editing, save the file
#; NOTE
#: You should verify your changes by running OpenJUMP now as described in the next step.

=== '''Formatting message''' ===
Messages can use variables. For example :
#: <pre>openjump.error = The layer {0} contains invalid features.</pre>
Note that in case a message contains variables (and only in this case), apostrophes must be doubled :
#: <pre>openjump.error = L''attribut {0} existe déjà!</pre>

=== '''Verification''' ===
# start openjump with the start script for your platform
# check the translated strings

=== '''Release''' ===
# send me the modified properties file to sstein@geo(....) or
# to the development mailing list http://lists.sourceforge.net/lists/listinfo/jump-pilot-devel

After adding it, the nightly built of the next day should include your translation. I hope that is detailed enough :o) If questions appear please don't hesitate to contact me (Stefan/sstein) or the mailing list.

== '''On new translations''' ==

* please simply make a copy of the file jump.properties file and rename the copy to your language abbreviation (e.g. the swedish one should be like: jump_se.properties)
* translate everything
* put the properties file into '''language''' folder

== '''Problems with "special" characters''' (e.g. translation of asian languages or european accented characters)==

Use an '''UTF-8''' capable editor (notepad, notepad++, jEdit ...) to do the translation and save a '''UTF-8''' text file eg. as '''jump_zh_HK-utf8.properties'''.

In a second step convert the whole file
: Convert the utf-8 to unicode literals using native2ascii.exe (part of the java development kit, e.g. C:\Program Files\Java\jdk<version>\bin\native2ascii.exe
:<pre>native2ascii.exe -encoding utf8 jump_zh_HK-utf8.properties jump_zh_HK.properties </pre>

or

:Convert via web service copy & paste from/to the text editor and save with encoding ISO-8859-1 (latin-1). To find online services use your favorite search engine with keywords like "online converter unicode literal" or "online escape unicode". Two examples at the time of writing [Apr.2012] include
: http://www.htmlescape.net/javaescape_tool.html
: http://www.snible.org/java2/uni2java.html

== '''Useful tools''' ==

=== Attesoro ===

* intuitive to use properties file editor with '''automatic''' utf-8 escape char support
* get it at
** http://attesoro.org/translate.html
** mirror of the version at the time of writing (http://sourceforge.net/projects/jump-pilot/files/tools/attesoro_1_8.jar)

=== 7zip ===

* can be used to unpack jar files (which use the zip compression)
* a graphical (un)packer utility
* available for windows or unofficially for several other operating systems (see downloads page) at
** http://www.7-zip.org/

=== jEdit ===

* a java based text editor
* support all major text encodings
* mighty search and replace engine
* get it at
** http://www.jedit.org/
* If you use jEdit, you might want to download the macro called "Escape properties" on jEdit site.

Loading an ASTER GDEM (Global Digital Elevation Model) tif file in OpenJUMP could be difficult as OpenJUMP correctly decodes the geographic position of the file (which is automatically saved in a .tfw file in the same folder of the TIF) but it doesn't decode file raster data.
The file is displayed into the layer tree of OpenJUMP but not in the view.

In order to correctly load these files in OpenJUMP they should be transformed using an external software.
This procedure shows how to transform an ASTER GDEM file using ''ImageJ with Bioformat plugin''

[[File:raster_info_2.png|800px]] 
A second panel is used to define transparency parameters 
[[File:raster_info_3.png|800px]] 
 
 
=== '''Raster Statistics''' ===
On menu '''Raster>Statistics>Compare selected Grid raster layers''' there is a panel that calculates and compare cell statistics of selected raster layer (min, max, mean, ect) per band. Alpha chanel will be displayed as band number 4. 
Select one or more single raster layers. Click on '''Raster>Statistics>Compare selected Grid raster layers'''.Select the file you need to get information and click 'OK'. The Result viewer will be opened showing the info in a table which eventually can be saved as .CSV file 
[[File:Raster info 4.png|800px]] 
 
 

=== '''Profil Graph''' ===
'''Profil Graph''' allows to generate an elevation profile on a Sextante raster. To calculate some statistics parameters. To generate a Sloper profile of the elevation one 
Click on '''Raster>Profil Graph''' tool. A new dialog will be open.
 
 
[[File:profile01.png|800px]]
 
 
'''Profile plot''' - User can choose on which raster to draw the profile and which is the display unit (meter, foot or unknow) of the raster. Note that the display unit has only an effect on the label profile and on raster statistics. It is not an unit converter
 
The following check boxes allow either to draw a linestring as trace or to use a selected linestring as base trace for the profile, These option will be operative wnhe the dialog is closed using the '''OK''' button
 
'''Options''' - The Options fileds allow to define the text on both horizontal and vertical axes of the profile
 
 
The following image shows a generated profile after clicking the 'OK' button and drawing a linestring on the raster as trace. The profile is saved into the Result viewer and it can saved either as .PNG or as .DXF
 
 
[[File:profile02.png|800px]]

'''B''' button open an option dialog where the user can modify the titles of X and Y axes, the scale of the axes (linear or logarithmic, the bounds of the X and Y data
 
'''C''' button opens a table where the user can check, for each point of the section the following information: elevation read on the single pixel, Planet distance (horizontal distance) between two progressive pixels, Terrain distance (real distance) between two progressive pixels, relative slope and absolute slope in degree progressive pixels.
 
'''D''' button allows to open a new dialog where the user can choose to draw a new profile defining relative or absolute slope, The slope profile is automatically put side-by-side to the elevation profile
 
'''E''' label shows only the unit which choosed by the user on the dialog before
 
'''F''' button open a panel showing statistic informations about the profile. info can be saved as .HTML file
 
'''G'''
Calculate travel time fileds allow to calculate an approximate traveling time if the profile is drawn on a route. User has to define flat, up and down speed. The result traveling time is shown in the ''F'' statistic info of the profile
 
 
=== '''Raster histogram''' ===
This option is available on menu '''Raster>Statistics>Create Histogram plot'''
[[File:rasterhistogram.png|800px]] 
 
 

=== '''Pixel Inspection''' ===
Pixel inspection , enabled via '''Raster''' menu is a powerfull tool to inspect single values of a raster cell. 
By moving the cursor over a the raster, single cell value is displayed on the left side of lower system panel. 
Clicking on the view will display the cell value. Values are saved on a temporary vector layer.

'''Profile plot''' - User can choose on which raster to draw the profile and which is the display unit (meter, foot or unknow) of the raster. Note that the display unit has only an effect on the label profile and on raster statistics. It is not an unit converter
 
The following check boxes allow either to draw a linestring as trace or to use a selected linestring as base trace for the profile, These option will be operative wnhe the dialog is closed using the '''OK''' button
 
'''Options''' - The Options fileds allow to define the text on both horizontal and vertical axes of the profile
 
 
The following image shows a generated profile after clicking the 'OK' button and drawing a linestring on the raster as trace. The profile is saved into the Result viewer and it can saved either as .PNG or as .DXF

The toolbar of the profile allows to generate other informations
[[File:profile03.png|800px]] 
 
'''A''' buttons allow to zoom and navigate in the pictures
 
'''B''' button open an option dialog where the user can modify the titles of X and Y axes, the scale of the axes (linear or logarithmic, the bounds of the X and Y data
 
'''C''' button opens a table where the user can check, for each point of the section the following information: elevation read on the single pixel, Planet distance (horizontal distance) between two progressive pixels, Terrain distance (real distance) between two progressive pixels, relative slope and absolute slope in degree progressive pixels.
 
'''D''' button allows to open a new dialog where the user can choose to draw a new profile defining relative or absolute slope, The slope profile is automatically put side-by-side to the elevation profile
 
'''E''' label shows only the unit which choosed by the user on the dialog before
 
'''F''' button open a panel showing statistic informations about the profile. info can be saved as .HTML file
 
'''G'''
Calculate travel time fileds allow to calculate an approximate traveling time if the profile is drawn on a route. User has to define flat, up and down speed. The result traveling time is shown in the ''F'' statistic info of the profile

=== '''Compare Grid Raster Layers''' ===
''''Compare Grid Raster Layers'''' works only with single band raster layers. It allows to compare different selected raster layers to compare different informations (max/min cell values, nodata cell values, number of valid cells, number of nodata cells, number of columns/rows, min x/y, cell dimension).
Select one or more single raster layers (1). Click on '''Raster>Statistics>Compare Grid Raster Layers''' (2). An Info panel will display all the info in a table (3).
