Currently, it is forcing the polygon to draw at an absolute elevation (looks to be above sea floor?) You can clamp it to the surface, which will essentially 'drape' it over your elevation / DEM. To fix the issue the KML syntax is <altitudeMode>clampToGround</altitudeMode> If you could post some of your raw code, might be able to help with ...

After displaying your points as X,Y data you need to save the layer to a spatial format that is useable in the ArcMap geoprocessing tools. You can right-click on the points in your table of contents and choose to export them to a shapefile (or other format). Once this has completed, choose the option to add the new layer to the map. Use this new layer as ...

Suggested workflow: Draw perpendiculars to road segments at regular step Interpolate them to 3D lines using DEM Convert vertices to points Find lowest point If it is “close enough” to centreline, road runs in depression This shows the test I’ve applied to check if already existing streams are matching newly developed DEM: You can also check results ...

You may click on some automatic tie point (the one you want to assign the elevation to), and then click: After clicking the correct position on more than 2 images, the coordinates will be displayed in the up-right. Change the point type from "manual tie points" to "3D GCP" and then change the elevation value. Repeat this for 3 points, well-distributed on ...
