• Or how to make a decent map

Topics

• Moving IDRISI raster files to ArcView 3.x
• To ArcGIS 8.x (maybe ArcView 8.x)
• Converting vector AV 3.x files to raster and
  importing to IDRISI
• Same with ArcGIS

3
Export from ArcView 3.x

• Export the desired image from IDRISI to a format
  that ArcView understands
• Import the file saved above into ArcView and then
  save as a Grid
• A GRID is ESRIs name for an image
• In IDRISI
• File/Export/Software-Specific Formats/ESRI
  formats/ArcRaster
• Or type ArcRaster in the GO window

4
Export from IDRISI

• Select ArcRaster format
• Select IDRISI to AV Raster Binary

IDRISI file

• Name the output file (can be the same) and
  where to put it.
• The filename will have the extension .flt
• There will be another file with the extension
  .hdr but .flt is the one you want to use

5
In ArcView (AV)

• Launch AV
• Get this?
• Click with a new view
• Click OK

6
Next

• You get a dialog asking Would you like to add
  data to the view now?
• The answer is NO
• An empty viewopens ?

7
Import the data

• First you have to set up AV to work with grids
• Load Spatial Analyst from Extensions menu

Click
8
Import the data

• Select menu item File/Import
• Select Binary Raster files
• Find and select your data file type .flt
• Save it as an AV Grid wherever you want
• After save you will get a dialog asking Add grid
  theme to the View?
• The answer is YES
• Bingo, the grid version of the image is added to
  the view

9
AV3.x Booby Trap
When saving in AV3.x always browse first and
then name the file!
10
Remember
Navigage then Name
11
The View

• Add the image (grid) to the view
• Probably wont be what you want so you will have
  to play with it in AV
• Double click on the legend to open the Legend
  editor
• Change the classification to match your data
• Change palettes or palette colors
• Click Apply to check then the go-away box

12
Happy with the view?

• Now go to the layout document
• Make sure that what is in the view is what you
  want on the map (layout)
• You can zoom the view in and out and whatever
  shows in the view will be what is put into the
  layout
• Under the View Menu click on Layout
• Choose template
• Map opens
• Usually not exactly what you want so edit

13
Messing with the Layout

• You can select objects
• Resize them
• Change change them
• Double click text to edit
• You can insert new objects
• You can change the colors of things
• You can take apart the legend and rearrange it
  but make that the absolute last thing you do!

IDRISI to ArcGIS

• Operations in IDRISI the same
• Open ArcToolBox
• Open the Import to Raster tool box
• Select the Floating point data to Grid tool
• Browse to the .flt file you created in IDRISI
• Specify an output location and file
• Click OK
• May take a minute or so to process
• Add to a map

From ArcView to IDRISI

• In this example I
• Exported ELEV to ArcView
• Use ArcView to make a set of 50 contours
• Saved the resulting shape file as a shape file
  (that is the easiest way to put a shape file
  where you want it)
• Went to IDRISI and used SHAPEIDR to import the
  shape file to a IDRISI vector file

OK, Make a Map in AV3

• Changed the symbolization by double clicking on
  the legend in the table of contents
• Picked a range of classification
• Picked a color ramp
• Clicked Apply when happy clicked go away box
• Then selected a layout template
• And messed with it

24
Messing with it

• Double clicked title and entered a new title
• Changed font sise
• Dragged to center over map
• Selected map and then Layout/add neat line
• Set style and width, clicked OK
• Dragged handles so that it the neat line covered
  in edges of the map

25
More Messing

• Selected the Legend
• Eliminated the No Data category since there was
  no area of no data
• Moved the symbol for the contours out of the
  legend by dragging
• Selected all the remaining legend items by
  dragging a selection box around them
• Clicked Graphics/Group
• Now is one chunk

26
Yet more messing

• Selected the legend again
• Drew a neat line around the legend and gave it a
  light blue fill.
• Under Graphics sent the box back
• Dragged handles so that the box just surrounded
  the legend items
• Selected both the box and the legend and Grouped
  them made one chunk

27
Ye Gods, More messisng

• The scale is gray because map units not set
• Set the view properties map units to feet
• Deleted scale bar
• Inserted scale new scale bar and made it the way
  I wanted it (tricky, may not want to do)
• Resized the North arrow
• Used the arrow keys to get things lined up
• Exported as a .jpg file
