Merekam ArcMap Project (*.mxd) ke CD/DVD/USB Flashdisk

Jika anda ingin mengopi sebuah project ArcMap (*.mxd) ke media lain, maka anda membutuhkan script MXDPackager.
Syaratnya, semua file layer atau shp dan project diletakkan dalam satu folder. Jadi, nantinya anda hanya mengopi foldernya saja ke media lain.
MXDPackager merupakan sebuah script untuk merekam ArcMap project (*.mxd)
ke dalam USB Flashdisk/CD/DVD dan tersedia dalam format *.bas
Berikut langkah-langkahnya:

1. Extract MXDPackager. Nama file hasil extract adalah PackageMXD end.bas

2. Buka ArcMap project (*.mxd) yang ingin Anda copy ke USB Flashdisk/CD/DVD

3. Kemudian klik menu Tools - Macros - Visual Basic Editor .


4. Pada jendela Project di  sebelah kiri tampilan Visual Basic Editor, klik
    kanan pada Project (nama file ArcMap project.mxd), lalu pilih Import File.


5. Browse pada file PackageMXD end.bas klik Open

6 .Di bawah Project (nama file ArcMap project.mxd) kini tersedia folder
    Modules dan di dalamnya terdapat PackageMXD.

7. Double klik PackageMXD, sehingga script-nya akan tampil.
    lalu klik Run atau tekan F5.


8. Browse folder untuk menyimpan hasil kerja MXDPackager. Klik OK


9. Muncul jendela yang menanyakan, apakah Anda ingin menyimpan seluruh
    layer (klik Yes)  atau seluruh layer di clip sesuai dengan dataframenya (No)


10. Jika Anda klik Yes, akan muncul jendela kecil berikutnya yang menanyakan,
      apakah Anda ingin menyimpan seluruh layer baik yang visible maupun
      invisible (Yes)  atau hanya yang visible saja (No)

IMAGE CLASSIFICATION EXERCISE USING ILWIS 3.3

1. Open ILWIS software by double clicking the ILWIS icon on the desktop, and
    you will see the following opening menu. In this opening menu, click the open
    file icon, so that you can select a folder named DATA_ILWIS in C:\ drive, or any
    other folder name specified by your instructor. As you can see here, there is no
    file available for working.
    However, actually there is an image dataset prepared for your exercise,
    although it is stored in ERDAS 7.* format (*.lan)

Aligning Themes in a View

Aligning raster data with unprojected vector data in a view

If grids or images you are using have been projected in a package such as ARC/INFO,
they can be aligned with vector data in decimal degrees. Since the grid or image does not
project in ArcView, simply project the view. The unprojected vector data will project to
align with the raster data.

To align your raster and vector data :
1. Determine the projection parameters used when your image or grid was projected.
    For grids, this information appears in its prj file. For images, check any available metadata
    files.
2. Add the image or grid to a view. Also add the unprojected vector decimal degree data.
3. From View Properties, select Projection to display the Projection Properties dialog box.
4. Set the view’s map projection to match the parameters of the grid or image. If the
    parameters of the projection do not match those of ArcView’s standard projections,
    try using a custom projection. Use the table below as a guide.
5. Click OK on the Projection Properties dialog box.
6. From View Properties, set the Map Units of the view to match the projected units
    of your image or grid. For example, if your image is projected to State Plane feet,
    set the Map Units to feet.
7. Click OK on the View Properties dialog box. ArcView redraws the view using the
    projection you chose, and your themes should align.
