For the most part, when I’m modelling houses for clients, I have access to the terrain survey data in either geodetic points or contour lines which I can easily convert to terrain using Toposhaper. However when I don’t have this this data, things get painful and I’m hoping someone with more experience has a solution.
Currently, my workflow is as follows:
- Go to my local GIS Map, turn on contours
- Use the windows snipping tool to get the image
- Import into Sketchup and manually trace every contour line
- Manually place each contour to the correct height.
This is extremely time consuming and never as accurate as the original contour map. I have tried using CorelTrace and other vector conversion tools to generate a vector version of the image with unsatisfactory results.
I assume the data in GIS was vector to begin with - is there any way to bring that directly into Sketchup? Even if I could bring the lines in on a flat plane would be a huge improvement - it’s the tracing that’s driving me nuts.
For reference, I am using https://maps.crd.bc.ca/Html5Viewer/?viewer=public for GIS data. Navigating into their services directory I find this: https://mapservices.crd.bc.ca/arcgis/rest/services/CRDcontours/MapServer. I am able to save a kmz file but Sketchup will not import it and I do not have access to ArcGIS software.
Any help would be appreciated.
