ARCSCENE TUTORIAL PDF

3D data can be displayed and navigated using the ArcScene Application. in this case we will add an aerial photograph (e.g. aerial 5 in the tutorial data folder) . About This Tutorial. This article describes the steps required to load and display topographic, geologic, and cultural data in ArcScene and presents several. This tutorial is an introduction to ArcGIS 3D Analyst, an extension for ArcGIS. The extension needs to 1 From the 3D Analyst toolbar click the ArcScene button.

To list data by source will display the storage path above the layers.

In the Export Map Dialog, you should check the option to Save World Filewhich will save some georeferencing information for the image. Before we get into exporting the images we should think about resolution. Your clipped groundplan image can be imported directly into Google Earth and registered precisely using your model frame.

Note that you can adjust the size and rotation of symbols. At the end of the tutorial we create a 3D model from these that we can play with and generate renderings from a tool called ArcScene. You can quickly learn the name and more about its capabilities. Later, you may add new subfolders to hold the resources that are used and created by other applications.

Export your Frame polygon with the Clamped to Ground option checked. Inspect the model to see if it makes sense.

You can use the Advanced symbol swettings to read the height for each symbol from an attribute. There is no 3D globe surface provided in ArcScene.

Then we make a copy of this layer and change the symbol to a sphere that has its base height set as a constant value of We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground.

By the time we get around atcscene exchanfing the model between a number of tools, you will appreciate the utility of having a retangular model with a vector clipping frame that can be used arczcene register the various parts of the model as we move them into various tools that do not tutorizl georeferencing.

Rather than usng a sensible default display properties for images of this kind, ArcMap insists on stretching the color ranges all out of whack. Use the Add Data button to add your new point shapefile to ArcScene. In addition, certain tools and options displayed arscene may be specific to ArcScene and therefore not available in other applications. Save your clipped elevation model as a tiff or an Imagine Image format.

Introducing the ArcScene user interface

And images are always rectangular. Now that you have a 3D model you wil want to try flying around and saving some images that you can use to describe aspects of your site. Think about the sort of grapnhical hierarchy thou would want in a reference image that will be draped on an aerial photo in your model. Thinking about it another way, many programs like AutoCAD and Sketchup will choke if you try to drape a texture with more than, say x pixels We represent the column for the sign as a cylinder that has its base on the elevation surface and is extruded by 10 meters.

The following notes will provide links to documentation that will provide necessary details about how to add your data, adjust the display properties and to navigate your model in 3D. Finally, we will select and save the buildings that occur within our model study area. For some reason, ArcMap 10 and Go to the Layer Properties for your groundplan and in the Symbology properties, change Stretch to None, and uncheck the option for Gamma Stretch.

Now that you know how to create new geometry and navigate to diffeent places you are ready to investigate visibility. Open your geoprocessing toolbox by clicking the little red toolbox icon on ArcScene’s toolbar.

The following links may help to jog your memory after an in-class demonstration. Then we can navigate to different places in the model check whether the sign is visible.

From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer. Adjust the tuutorial of your new building to set their base heights and extrusion. This tutorial will take this a step further.

A good resolution for your context image may be about a half-meter per pixel, which is good enough to see distinguish buildings, roads, cars, etc. Our rough 3d model can be useful for investigating how places interact visually.

Later we will investigate how we can create and preserve view corridors after existing buildings are removed in anticipation of developing a new transit-oriented development.

Make sure that the Clamped to Ground option is unchecked. We use this tool to export the buildings and the frame from your scene. Export your Buildings to a New Shape File If necessary, return to the bookmark you saved for your model frame. Note that dockable window controls can be moved around the display to customize your view. It is convenient to plan our model with a rectangular boundary. It may be helpful to make the sky blue. Note that if you het a cryptic error message when you try to do this it is probably because you need to change the File Type from geodatabas feature class to Shapefile.

When saving, be sure to set Save Files of Type to Shapefile. From ttuorial pulldown menu on the Draw toolbar, choose Convert Graphics to Features. Shift-click to select more than obne building.

Adjust the Base Height property of your point so that it shows up on the surface. ArcScene is very similar to ArcMap, except it has some additional features for visualizing and navigating data in 3D. For the tutorlal image, you don’t necessarily need a very high-resolution image.

We will look at a few additional types of data that let us represent the form of places in three dimensions, or at least two-and-a-half dimensions! If you export an image from arcmap with the Georeference option checked. Our clipped dataset is going to include:
