A. Go to Synthetic Area

Click this option to switch to a 'Synthetic Area' for modeling purely hypothetical (or idealized) groundwater systems. A synthetic model is not tied to a particular geographic location in the map display. To switch back to a 'real-world model' from the synthetic model mode, click 'ResetModel' under Other Tools.

B. Geometry Locked and Geometry Unlocked

When a user draws a conceptual feature (polygon/zone, polyline, etc.), nodes (small circles are automatically displayed along the line segment/perimeter for “instant” editing of the geometry by click-dragging nodes into desired locations. However, in some cases displaying these nodes will obstruct a key conceptual feature or part of the background image, and the nodes may be unintentionally moved if the nodes are accidentally selected by the cursor.

To disable this default setting, click the ‘Geometry Locked’ button. Doing so well “lock” all present geometric features (i.e., they are no longer editable or clickable) and feature nodes (circles) will no longer be displayed. Any new geometric features added will still be editable until the user clicks ‘Geometry Locked’ once more.

To make all geometric feature editable/clickable, click ‘Geometry unlocked’

C. MakeVideo

Clicking this option will open the HSA Video Maker tool. The tool allows generating a video from a previously executed simulation (saved locally or on the server), or through "live" screen capture.

D. ImageGeoReferencing

This option opens the MAGNET Georeference Tool for transforming a digital image/map to a spatial reference system (i.e., locating the image to a real world location).

E. Ruler

The Ruler feature is used to measure the distance between two points. To use it, lick ruler and then click point 1 and point 2 of interest. The distance between the two points will then be displayed. Note that the Haversine formula is used to the calculate distance between two points on the Earth's surface. In the calculation, 6378137 meters is used at the Earth's radius.

F. Publish This Model

After creating and simulating a model, select ‘Publish This Model’ to launch the Model Publishing Options window. This window allows uploading three image files related to model results and one video animation. Users should also provide a Model Name and a Model Description in the text boxes provided.

Edit Published Models

At any time, users can edit the settings of any of their published models by clicking the ‘Edit Published Models’ button. This opens the Edit Published Model Options window.

Base Flow Separation

This option opens an interface that facilitates separation of base flow from a stream hydrography. Users can add their own (properly formatted) stream flow data, or they can use the USGS Sensor Data tool to extract data from stream gaging stations and directly load the data into the Base Flow Separation tool.

Overlay myImage

In some cases, it may be helpful/necessary to display an image layer in the map display (e.g., site drawings, GIS layers/maps of land or subsurface features, etc.).

Begin by using ‘Overlay’ option to open the ‘Overlay an Image on Maps’ menu. The text following “Note that:” provides details on the image requirements and the directions for specifying the image pathname if the web browser does not support local resource accessing. If the browser does support local resource accessing, click on the ‘Browse…’ button to navigate to the image location and open the image. Note that when using the ‘UpLoad’ option, the user must specify the overlay extent using the text boxes next to ‘Top Latitude’, ‘Right Longitude’, etc.

Use the Remove option to completely remove the background image from the map display.

Use the Hide/Show Option to hide and re-display the background images in the map display.

Overlay CnptImage

If streams and/or lakes from the MAGNET Data Center (server) were imported into the groundwater model as conceptual features (internal boundary conditions), clicking this option allows adding the surface water features to the map display. (Importing steams/lakes from the MAGNET Data Center is done under the Simulation Settings tab of the Domain Attributes menu).

Begin by using ‘Overlay’ option and selecting the opacity for the Cnpt Image overlay.

Use the Show/Hide Option to show or hide the Cnpt images in the map display. (After clicking 'Overlay', the user may have to click Show a first time before the CnptImage will be displayed.)

Use the Remove option to completely remove the Cnpt image from the map display.

Server Streams and Server Lakes

Use these checkboxes to add to the map display any extracted lakes and/or streams as conceptual polygons or lines, respectively. Server streams and lakes are added under the Simulation Settings tab of the Domain Attributes menu (see Streams and Lakes from Data Center section).

These checkboxes do not work if Server Streams / Lakes are not included in the model.

The display options (color, line thickness) for different order/size streams and lakes are controlled in the submenu for streams and lakes from the Data Center.

Check the box next to Server Streams or Server Lakes to initiate processing of the extracted features. After a few moments, a prompt will appear where the user can specify the opacity of the new overlays. Uncheck the box to remove the layer from the display.

Note that, when overlaying the server streams and/or lakes, the objects are automatically placed on top of the Main Model results (e.g., Contours and Vectors). To return the Main Model results to the "top", click 'ShowOverlay' / 'HideOverlay' under 'Other Tools'. (Similarly, to place server lakes and/or stream results back on top, just uncheck and recheck the box next to Server Streams / Server Lakes.)

Decrypt Files

This option is meant for Premium IGW-NET users that want to decrypt their downloaded model results that are encrypted at download.

To decrypt multiple encrypted files, zip all of the encrypted files into one (.zip) folder.

If an encrypted (.zip) folder contains encrypted files, change the file extension (.zip) to an extension other than .zip, decrypt this encrypted zip file first, then change the extension back to '.zip' and decrypt files inside the zip folder.

All decrypted files will be zipped for download.
