Now that we have set up our context model in rhino, we are ready to cut out the area of the model that we are going to articulate for our surround and design models. YOu should now see a colorized orthophoto with batheymetry from the NOAA navigational chart draped on your terrain mesh. Then select our oundplans/context_ortho_bathymetry.jpg. When prompted for amesh, choose your mesh. Use the RhinoTerrain > Imagery > Orthophoto Map on DTM command. For a better idea of what is happening, we can drape the orthophoto that e exported frm ArcMap. The terrani model is cool but lacks important details.

TO keep things neat, you should move this new mesh to a layer named Context Mesh Drape the Context Orthophoto For fun,switch your perspective window to Render Mode. You have to make sure to choose the Accept option to finish it off. Select this pointcloud object and choose Rhinoterrain > Mesh > Create Terrain Mesh. Our first mesh is made using the pointcloud that resulted from our import of the asciigrid. Since some of our design documents reference elevation in feet, we will now use the Units command in rhino to scale the model to feet. Import your Surround Frame and Context Frame. At the next prompt, choose Import as Pointcloud. When prompted for a coordinate system, choose Use Input Data Coordinate System. If Rhino does not recognize the ascii file that you made with arcmap, try changing the file-type pull down to recognize "all filetypes" - not just hose with a. Otherwise it will go on your default layer, and you will have to move it later. Before importing this ascii Grid it is a good idea to create a new layer called asciiGrid and make it the active layer in Rhino. Importing the asciiGrid is accompished with the RhinoTerrain > Import > ArcInfo AsciiGrid tool. > ArcMap Shape File to import your frames. But for now, just use the Condor_St_wilds_master.3dm file provided in the folder manuscripts\cad. If you are opening a new Rhino File, choose the template for Large Models in Meters. Our workflow now involves an exchange with Rhino. The RhinoTerrain plugin bridges the gap between rhino and GIS.

GIS is a great tool for bringing together diverse and large datasets, but at this stage in its evolution it is notĪs great a tool for 3d editing as Rhinoceros. Import and Arrange your Source Data in Rhinoceros You wil find this exporrted file in work/gis/schemes/ned_10m_context_gridascii.asc So that the resulting ascii file matches perfectly with the edge of our context frame. Note that we set the Processing Extent environment variable to match the extent of our context frame. This is accomplished with the Raster to Ascii tool in the Conversion Tools>From Raster toolbox, as described in the Digital Elevation Models tutorial. The best way to get a GIS - based elevation model to Rhino Terrain is by exporting it to an AsciiGRID. Take a look at our raster elevatiion model The key thing is that eaxh image is clipped exactly to one of the frames.Įxport the Terrain Raster to an Ascii File You can also see other images i the groundplans folder that we exported from ArcMap the same way. It ia named, hargreaves_plan_design_frame. Then we will scan the design, and crop it in photoshop and put the result in your Manuscript/Groundplan_Images folder.

Then you can print this out and use it as a base photo for developing a design using colored pencils on trace.

We will use ArcMap to export an image or a pdf of the aerial photo with the design frame on it. The first step is create images of the existing condition and of your design that are clipped precisely to the design frame polygon. The process for creating these is discussed in the page, Creating Geo-Registration Frame and Groundplan Image Create a Groundplan Images YOu will also want to have aerial photographs or other groundplan images that fit perfectly within theĬontext and Surround Frames. One each for your context frame, design frame and surround frame. see Obtaining Digital Elevation Models Create a Georegistration Frames and Groundplan Images For more information about obtaining these raster elevation models. This is an elevation model from the United States Geological Survey that we will use as the base model or our design.
