If you created multiple shapefiles (one per class), the results are not added to the Data Manager or Layer Manager. If you right-click on the shapefile in the Layer Manager and select View Attributes, the Attribute Viewer lists individual polygon records for the different classes, organized by the CLASS_ID and CLASS_NAME attributes for example: The following image shows an example of this step for a single shapefile with four classes:

Double-click the shapefile in the Layer Manager to display the Vector Properties dialog, then assign unique colors and line properties to the individual classes as needed. If you created one shapefile that contains all classes, that shapefile is added to the Data Manager and Layer Manager, and it appears in the Image window. See the ENVI Servers topic for more information. The ENVI Server Job Console will show the progress of the job and will provide a link to display the result when processing is complete. To run the process on a local or remote ENVI Server, click the down arrow and select Run Task in the Background or Run Task on remote ENVI Server name. To apply the saved task settings, click the down arrow and select Restore Parameter Values, then select the file where you previously stored your settings. Note that some parameter types, such as rasters, vectors, and ROIs, will not be saved with the file. Click the down arrow and select Save Parameter Values, then specify the location and filename to save to. To reuse these task settings in future ENVI sessions, save them to a file. If you selected the One Vector Layer Per Class option in the previous step, ENVI will create multiple shapefiles and will automatically append the class names to the root filename.

Specify the path and filename for the output shapefile in the Output Vector field.

One Vector Layer per Class: Create multiple shapefiles, one per class.

Single Vector Layer (default): Create one shapefile that contains all classes.

Optionally choose one of the following from the Output Method drop-down list: In order to have the needed rivers, Ive set the pixels with a value of 5000 or less (small rivers and land) as transparent and all ive got are the major rivers in raster format.

The Export Classes section contains a list of individual class names that were imported. Sadly, the flow data is provided only as raster, and thus they cannot be upscaled or adjusted as vector lines, counting the whole dataset as an image.

The Convert Classification to Vector dialog appears.

Select an input classification image and perform optional spatial subsetting and masking, then click OK.

From the Toolbox, select Classification > Post Classification > Classification to Vector.

You can also write a script to perform this step using the ClassificationToShapefile task. In addition there are numerous libraries in Python and other languages that can help you with the conversion.Use the Classification to Vector tool to export selected classes to a vector shapefile. : Another online tool to convert between different GIS data formats.

Mapshaper: A online tool to upload many data formats, simplify it and download as GeoJSON. Method Open the file you wish to convert by selecting Layer > Add Raster Layer Open the raster translator by selecting Raster > Conversions. Ogre: A online tool to convert vector data to GeoJSON using the ogr2ogr command. You can access it using the URL above, it only supports GeoPackage which is a open OGC format for Spatial Data. We have created our open source own tool to convert Evaluation maps into GeoJSON that can be uploaded in Geodesignhub. Export Data in GeoTIFF formats To EXPORT the raster as a GeoTIFF, right click on the raster layer in the LAYER LIST, then SAVE AS. Beta tool Geodesignhub Evaluation Maps Converter

Please review the simplifying maps topic for tools and settings for simplification.

It is recommended that you remove all attributes and just keep the ones necessary to reduce size even more. In case the saved GeoJSON file is more than 4MB, it needs to be simplified.
