He played the timeline. The sun arced across the sky. The shadows moved realistically, rolling over the hills.

She nodded to Elias.
A dialog box popped up. It asked him to open Google Earth. He complied, the familiar blue marble spinning into view on his second monitor. He navigated to Seattle, zooming in rapidly until the pixelated blocks resolved into the familiar jagged skyline. He centered the view on the exact site of the Emerald Spine. He played the timeline

The head of the council, a stern man named Mr. Henderson, peered at the screen. "How did you get the topography so accurate? The last guy showed us a flat green slab." Elias looked at the next button: IMPORTGESURFACE
Elias sighed. He had the topography data—imported from a surveyor’s text file—but it was just a mesh of triangles. It didn’t look like the site. It didn’t have the trees, the neighboring roofs, or the texture of the reality his building was meant to inhabit.
| Challenge | Description | | :--- | :--- | | | Google Earth imagery is warped for visual appeal; precise alignment with survey-grade CAD data can require manual scaling/rotation. | | Image Resolution | Imported images are raster files; zooming too far results in pixelation. Vector data from GIS is superior for analysis. | | Terrain Resolution | Google Earth’s DEM is coarse (approx. 90m post-spacing outside the US), insufficient for detailed cut/fill calculations. | | Licensing Restrictions | Google Earth imagery is for reference only—commercial distribution of traced data may violate Terms of Service. |
