Yes, this is easily done using the Smart GeoFill tool. The procedure can be seen in the following tutorial: http://support.pcigeomatics.com/hc/en-us/articles/209938603-Smart-GeoFill
In Geomatica, check the attributes of your point layer. With the point layer opened in Focus, right click on the point layer in the Maps Tab and select 'View Attributes'. In the attribute table, the 'Entity Type' field should be populated with 'POINT'. If this field is populated with another value, like 'POLYLINE', then the output DXF file will be blank.
In order to accomplish this, you will need to add an entry to your 'userproj.txt' file so that you are able to change your UTM projection from meters to UTM feet. The following example uses 'irvine.pix' which is included with the PCI Demo data on the installation CD:
- 'irvine.pix' has a projection of 'UTM 11 S E000' assigned to it. You are able to view this information under the 'Files Tab' by right-clicking on 'Irvine.pix' and selecting 'Properties' > 'Projection'.
- In your "Geomatica_v91\etc" directory there is a file named "userproj.txt". To get "irvine.pix" into the feet units, you need to add the following entry at the end of "userproj.txt":
- ProjectionName "UTM11Feet" ! or any string to describe the projection
- ProjectionDescription ""
- ProjectionCountry ""
- MapUnits "UTM 11 S E000"
- Units "FOOT" ! U.S. Survey Feet
- Add the above entry into your "userproj.txt," save it and then reproject "irvine.pix" ("Tools>Reprojection") into this new projection.
- In the Reprojection window you can select this new projection by choosing "Other" from the drop down menu beside the "Earth Model" button and selecting the "User Projection" tab.
- You can validate this conversion by comparing the eastings and northings of the original "irvine.pix" file and the reprojected output. You should see that the geographic coordinates are the same, but the eastings/northings are in feet.
This example is specific to "irvine.pix." If you have UTM files that are in a projection different from "irvine.pix," for example "UTM 6 N E012," then you will need to add another entry to your "userproj.txt" for this specific UTM zone and ellipsoid.
Focus will automatically enhance a raster file when it is loaded into the viewer. Without this enhancement, many images (especially satellite images) would appear black because only a small portion of the histogram range contains data. If you want to open a raster file that you have exported from Geomatica in another software package, you have a few choices to be able to visualize the image.
- Permanently enhance the image in Focus. This can be done in Focus by right-clicking on the .pix raster layer in the Maps tree list, Enhance, Edit LUT, then click on the histogram. After you have applied the enhancement, go to Save in the menu bar at the top of the LUT Editor window and select Save Image w/LUT. You can save the permanently enhanced image in new image layers (recommended) or overwrite the existing image layers. The permanently enhanced .pix image layers can then be exported to another file format.
- Use the original Digital Numbers in your other software package. To be able to see the data in another software package, you will need to apply an LUT (perform a histogram stretch) within the program you are using. Note: You can change or turn off the default enhancement in Focus through: Tools, Options, Layers, default visual enhancement under Rasters.
When your image is viewed in Focus, it will often have an enhancement applied to it that allows it to be optimized for viewing with the human eye, often removing enhancements to your data will result in the image appearing dark and hard to see. When the same file is opened in most software packages such as ArcGIS it will not be optimized and will appear dark. In Focus you can customize your image and then export it with the visual enhancements preserved so that when viewed in ArcGIS it will appear the way that you want it to.
Go to the files tree list (under the File tab) in Focus, expand theraster layer, right click on the classified channel, and select View | As Pseudo color.Switch to theMaps tab then right click on the pseudo colored layer and select Properties to open the PCT Layer Properties window. Here you can specify what PCT to open with this image.
A shape file is a vector format but your classification results are in a raster format. Therefore all you basically need to do is to convert the raster to a vector format and then extract and attach the classification classes as attributes of the vector file.
The Import ASCII Table/Points Wizard allows you to import ASCII files into a project and convert them into vector-point data. Table values that combine coordinates with field research data can be imported to the Attribute Manager spreadsheet and converted into vector-point files that you can add to a project and open as layers in the view pane.
