Make sure the Show and Display Legend buttons are selected.Ĭlick the Color button. Set the Major interval to 5 m and Minor to 1 m. Select the boxes next Show Major Contour at and Show Minor Contour at. Right-click the DTM line in the Layers Control Panel and select Properties from the menu.Ĭlear the box next to Fill Color on Height Range. Move the cursor over the contours and note that the x, y, and z values are displayed in the status bar at the bottom of the network view.

Note: The DTM covers only a portion of the background image. The consecutive rows with the same tag in column S are ridges or gullies. Column S is used to designate break lines. In the Windows Explorer dialog, navigate to the file River_site.txt and then click Open. In the Layers Control Panel, right-click the DTM layers line and select DTM Builder. Use the Pan tool to drag the image around the network viewing panel.

Right-click and the cursor will display the hand (Pan tool). Note that the x and y coordinates are displayed in the status bar at the bottom of the network window. Click OK.Įxplore the image with the mouse. The coordinates of the Destination Rectangle are filled in from the world file ( River sitem.bpw) that is associated with image file. In the Windows Explorer dialog, navigate to the file River sitem.bmp, and then click Open.Select Add Background Image from the menu.Right-click the Background Images line in the Layers Control Panel.At the opening dialog, create a new file called DTM_and_River_m.xp.River_site.txt (topographic data in text format).Create a digital terrain model (DTM) from survey data.A DTM is created from survey data and used to assign inverts and create shapes of cross sections for a river model. sid, and others) are used as background images to layout a network. Part 1 – Adding a Background Image and Creating a DTM In this tutorial, a 1D hydraulic model of river is created using a background image for the layout and a DTM to assign elevations. An embedded tool in the software will generate the DTM from xyz data. The data is stored in file with name filename.xptin – filename. The application uses a Triangular Irregular Network (TIN) format. In order to access topographic data, it must be in the form of digital terrain model (DTM). Invert elevations, cross section shapes, and conduit lengths may all be obtained and adjusted in the user interface. You can use the tools in the application for automating the process of constructing a river model from topographic data. The cross sections representing each reach can be derived from topographic data. In river models, links are typically trapezoidal or natural cross-sections representing river reaches. River models employ the same link-node scheme that is used for pipe networks.
