DEM Generator
Introduction
The DEM Generator allows users to generate DEMs locally on their workstation and upload/merge them to a remote SymetryML project. This is especially useful if the dataset of interest cannot leave the user's workstation.
A remote project must exist on the SymetryML server before using the DEM Generator. For information on how to create a remote project, please see this guide.
Tutorial
Successful use of the DEM Generator involves the following three steps:
Specifying a remote project
Processing a local file
Uploading the generated DEM to the remote SymetryML Server
The remainder of this tutorial will guide you through these three steps.
Step 1 Specifying a remote project
Referencing a remote project can be done in one of two ways.
Manual Project Reference - Manually inputing the remote project information
Automatic Project Reference - Downloading the reference file which contains remote project information
Manual Project Reference
To specify a remote project, start the DEM Generator and click on Select a Destination button.
Input the following information:
Hostname - SymetryML URI
Username - SymetryML User ID
Secret Key - SymetryML Secret Key
Refresh the project list and select the remote Project as your destination.
Selecting the remote project will allow you verify it's schema.
Press Confirm to finish Step 1.
Automatic Project Reference
Download the project reference file
Start the DEM Generator and click on Select a Destination button.
Drag and drop the reference file
Input the password you used to generate the reference file.
Press Confirm to finish Step 1.
Step 2 Processing local file
After the remote project has been specified, it is time to choose a local file which will be converted into a DEM.
This can be done by either clicking on the Select a File button, or simply dragging the file into the DEM Generator
You will be presented with a file preview. After previewing the file, you click Next to move to the type mapping view where you will confirm that the attributes types have been assigned correctly. Right clicking on the attribute allows you to change its type.
Click Confirm to close the type mapping panel and finish Step 2.
Step 3 Uploading the DEM
At this stage you have specified a destination project, generated a local DEM, the only step left is click the Upload button.
Log back into your ML Toolkit environment and view the end result.
Advanced Project Options
Advanced project options (e.g., random forest, logistic regression, etc...) should be specified by the remote project during the project creation step. DEM Generator will then mimic those properties locally. If the remote project is empty, the DEM Generator will allow you to specify them locally. This can be done during Step 2, by selecting Next on the type mapping panel.
For more information on the advanced project options, please see the following section section.
