I was able to interface it with my basecamp program, where you can choose the datum field that is best. This particular topo map dates from surveys taken way back in 1962. I have seen signficant changes in the river ( and GE images) in the course of a single year. Many of the islands, shoals, cutoffs change almost every year. However, when the Nad27 topo map is overlain, there is a dramatic shift in the route and waypoints, since they are WGS-84 but the map is not.Īnother issue I would have is this river ( and I assume other similar far northern Canadian rivers) are not static.

I know from being there 4 times that registration of my route and waypoints using the GE mapped waypoints is accurate with reality. Here is a segment of my Yukon River race route map with waypoints (labeled in tenths of a mile beginning from Whitehorse). So you will get a position shift if you overlay the topo on GE. But the topo maps are referenced to NAD27 datum. How do you account for the differences in datum? Google Earth is set to WGS-84 datum ( not changeable as far as I know). In Google Earth choose File - Open - Navigate to the downloaded file. It is also what makes it difficult to stitch multiple maps togetherģ. The Collar is the border around a map with the legend, title, declination etc. The other problem with CanMatrix Maps is you can not get them Collarless. Canmatrix maps are my favourite because they have the most detail that paddlers might find useful.

Cantopo is the newest, but has the least amount content for paddlers. Canada offers Toporama Maps, CanTopo Maps, CanMatrix Maps (probably others too). What is an index? It is essentially a grid of Canada. There may be others but these are the ones I find most useful. These index files include Toporama collarless map index, CanTopo Collarless index, CanMatrix 50k index and CanMatrix 250k index. The Government of Canada has made KML/KMZ index files for use in Google Earth (a KML/KMZ file is a file that Google Earth can open). Get the Canadian Map indexes for Google Earth It really does help out and Go check out some other videos if you’re new around here as well.2.

So considering that this just took less than five minutes, it’s definitely a cool feature and it’s worth knowing for your architecture projects. The other way you have to do it is by getting a contour map, making sure it’s the right scale and everything and then scaling them up and doing spending a whole lot of time just drawing every single line on the contour map. This is actually really good considering that. And if we go into a shaded view, you can see that it’s just molded out that side completely. And we’ve now got a NURBS surface for that model. And we can go ahead and delete the group that’s underneath it. Going back to our perspective view, you can see that’s created a surface of the model.

And we’re just going to create a square as it says drag a window over area to drape. So With it unselected, we can just type in drape. And what we can do now is just create a drape over this. So from here, what we can do is enter our top view, and we’re just going to scroll out and go find it. Go ahead and delete this flat plane as well. And we’re just going to place that model into a rhino file. So all of these should should be fine as default, however, make sure you’ve got it on as a mesh, and you want the edges and faces everything as well. And we’re just going to find where we save that. Now moving back into Rhino, we can open up a new file, and we can file import. And we’re just going to go site for Rhino, we’re going to save that. Actually sorry, we’re just going to save this, we can just go save this as a SketchUp, eight version version of SketchUp. However, from here, we can now import this into Rhino. Now as you can That’s pretty gnarly, but depends what site you’ve got, it might not be this big. And all we have to do is go to a file geolocation show terrain. Now we’ve just imported our map of the site. So I’m just gonna go here somewhere in Nepal, because there’s a bunch of hilly spots said I’m gonna select the region. And you want to just try and pick out the spot that you want to get the terrain for and get a contour model of. You want to start off by going to File geolocation and then go at location. So first things first, you want to open up SketchUp, I’m just using SketchUp Pro, you can use this on SketchUp.

And it will take us a couple of minutes, I’m going to show you exactly how to do that right now. We’re just going to use Rhino and SketchUp. Hey guys what’s going on, I just wanted to quickly make a video about creating topography or a site contour model from Google Earth.
