16 May In this post we look at how to use ArcGlobe for 3D visualisations of large areas. One benefit of using GIS is the creation of 3D visualisations. 20 Jun Creating 3-D maps in ArcGlobe – a Grand Canyon fly through: Home The tutorial “Finding Digital Elevation Maps (DEMs) for use in ArcMap.

You have detailed data for the entire county. ArcScene loads all data into available memory and uses paging files if necessary. All data added to an empty ArcGlobe document is projected on the fly to this coordinate system. One of the most significant differences between ArcGlobe and ArcScene is how each application handles information management.
Ability to handle large volumes of data via caching. In global mode I might navigate here:. This allows me to set the scale at which this layer is visible. ArcGlobe is the best choice because of the following:. ArcScene is a 3D viewer that is well suited to generating perspective scenes that allow you to navigate and interact with your 3D feature and raster data.
Rotate an image either around the center of the Earth or around the center point of the image—doing global or local navigation. Animation move layer along path.
Vector features are generally rasterized and displayed according to their associated LOD, which assists in very fast navigation and display. Again, it inserts it under my Imagery layer argh so next I drag it on top, play around with the symbology set the non-visible cells tuotrial No Color, reset the visible cell colour, add a bit of transparency and reset the view:. Most of your data is within one square mile around a group of oil wells. ArcScene projects all data in an ArcScene document according to the first layer added to the document.
You also have vector data for the fire road network and streams. I generally accept this and click Finish.
Working with ArcGlobe and ArcScene
Make animations of the images you generate. ArcScene is the best choice for these reasons:. To visualize the oil wells in three dimensions to see the effectiveness and coverage of your bores. Your data includes a series of aerial photographs, road centerlines, parcel boundaries, building footprints, land-use regions, and points of interest. It also renders a representation of the surface of the earth more realistically than other projections.
Annotation features cannot be displayed in ArcScene. This is one of arcglob reasons why ArcScene is optimized for smaller study areas with less amounts of data. Although ArcScene is enabled for remote desktop access, performance can be very limited. This is a sampling of some of the more significant functional differences between ArcGlobe and ArcScene.
Arcglobs option is particularly useful with annotation feature classes, which can be draped on the surface or automatically billboarded to face the viewer. Usually, a planar projection, ArcScene is geared for those with smaller spatial datasets who want to examine a defined study area. Or you can use the mouse wheel to move in and out.
An ArcGlobe Tutorial
Toggle between the modes with the mode button: ArcScene renders subsurface data and volumes very well. You have control over the amount of downsampling that occurs with the raster data in ArcScene. You have building tutorjal, road centerlines, park areas, and transportation infrastructure data for a city, based on a prediction model for 15 years in the future.
Available with 3D Analyst license. Display of KML data. It is based on a global view, with all data projected into a global Cube projection and displayed at varying levels of detail LODsorganized into tiles.
Since ArcGlobe is designed to be used with very large datasets, you should cache your data for optimum performance. This allows for fast display and visualization as you zoom in and out, pan around, and navigate to different places in your ArcGlobe document.
The Table of Contents has three sets of layers turned on by default: For elevation data, you have a number of tiled DEM rasters that cover the entire county.
At first the global mode is set and you can pan around much like you would in ArcMap with a view looking straight down at the ground. When you click on the Tugorial image you get the Symbol Selector:. Supported, but not recommended.
