I’ve modified the Shapefile importer to add a geolocation option. Starting with an empty inch model, it will set the model location to the lower left corner of the import and scale everything appropriately. Just export it as a KMZ file and import it into Google Earth. While the calculations originally used elliptic interpolation of the radius (depending on the latitude), it appears that Google Earth uses the equatorial radius of 3963.2 miles and assumes the Earth is a sphere.
The new plugin: https://sites.google.com/site/spirixcode/code/spirix_shapefile_importer.rbz
The model: NorthEndz.zip (990.2 KB)
The KMZ file: NorthEndz.kmz (603.7 KB)
If you import the original shapefile (northendish.shp) into Google Earth, you can compare the two interpretations … they’re very, very close. I suspect that importing smaller regions would map more accurately. The shapefile import treats each lot as a separate entity as opposed to all of them plotted as one large flat area.
Hope this helps …
