7. Once you are satisfied with the results displayed and you want to save them into the system, click the SAVE
button.
8. The Management Selection dialog should not appear. Select where you would like the NDVI dataset saved
and click the ACCEPT button.
9. You have now successfully created and saved an NDVI dataset that can be mapped, printed, used in
another analysis function such as an input to an equation, etc.
How to generate a terrain analysis dataset. (ADVANCED)
Follow these steps to generate a terrain analysis dataset:
1. Go to the Analysis Menu and select Analysis Wizard.
2. The Select Analysis Type to Run dialog should now appear. Select the Terrain Analysis button from the list
of Analysis Functions. This analysis function does not support saving custom settings/setup. To run
this analysis function select either the Single Field button or the Multiple Fields button to run it.
3. You will now see the Select Data Filters dialog which will allow you to select the data you want included in
your analysis. Terrain analysis is performed on a single field at a time (unless multiple fields was selected).
Once you have selected your dataset filters, click the FINISH button.
4. The Analysis Editor will be displayed once the analysis completes, showing a preview of the spatial dataset
that was created. No editing is allowed in this editor and its purpose is more for a visual check of your results
before they are actually saved into the system. Tooltips should also be displayed as you move your cursor
over the grid cells on the map. At this point the data has not been saved and if you click the CLOSE button
your results will be lost and you will have to re-run the analysis function to get a new analysis dataset. The
mapped attribute can be switched to show the result attributes that are created. For a terrain analysis
dataset a number of attributes are created; Slope/Grade (raw) (dimensionless), Gradient Direction
(degrees), Curvature, Drainage Area, Drainage Intensity (dimensionless), Flow Direction (degrees),
Landscape Position, Stream Power (dimensionless), and Wetness Potential (dimensionless). A Dataset
Name entry is also provided where you can enter in a custom name that will be used to save the dataset in
the management tree.
5. Once you are satisfied with the results displayed and you want to save them into the system, click the SAVE
button.
6. The Management Selection dialog should now appear. Select where you would like the slope dataset saved
and click the ACCEPT button.
7. You have now successfully created and saved a terrain analysis dataset that can be mapped, printed, used
in another analysis function such as an input to an equation, etc.
How to search for spatial data using the Spatial Data Finder. (ADVANCED)
Follow these steps to run the spatial data finder to find spatial data:
1. Go to the Analysis Menu and select Spatial Data Finder.
2. The Spatial Filter Type Selection dialog will appear. This dialog displays the current spatial filter groups and
filters that are in your system and allows you to select a filter to run, edit, delete or to create a new spatial
map or layers.

To create a new spatial filter click the Add New... button.

To create a new spatial filter that is based on an existing spatial filter that you want to modify and
save a unique version of, click the Add Copy... button.

i. The Name/Description dialog will now appear. This dialog allows you set various
descriptive items related to your new spatial filter. Click the NEXT> button once you are
finished with the entries.
ii. The Select Spatial Filter Items dialog will now appear. Select the items that you would like
to use to filter spatial data with. Also you must select a merge level for the spatial results
using one of the items you have selected for your filter. Click the FINISH button when
finished.
iii. You will now return to the Spatial Filter Type Selection dialog. Your new spatial filter will
now be listed under the Spatial Filter Group that you selected.
3. Select your spatial filter and click the NEXT> button to run it.
4. Use the filters on the next dialog to select the desired information to return to map.
5. The filter results dialog will now appear to show the datasets found by your filter. Click NEXT> to continue on
with the datasets found by the filter.
6. The Spatial Filter Results dialog will now appear showing a preview map of the results. You have the option
to either add the results to the currently active map or create a new map with the results. Click FINISH to
map the results.
