How do I get contours from Google Earth to SketchUp?
Creating Contours from Terrain in SketchUp
- Software Required: SketchUp.
- Open up SketchUp and click on the add imagery icon.
- Locate the area you want, and then click on select region.
- You’ll now draw a rectangle to define the area in which the contours area generated.
- a.
- b.
What does a cliff look like on a topographic map?
Cliffs – Very steep slopes, sometimes vertical or even overhanging. Represented on the map by very dense contour lines; when the cliffs are over hanging, the contour lines might overlap.
What are the 5 major terrain features?
The five major terrain features are: Hill, Ridge, Valley, Saddle, and Depression. The three minor terrain features are: Draw, Spur and Cliff.
What does a Depression look like on a topographic map?
Contour lines that show a depression, crater, or sinkhole on a map are represented by dashed lines (hachure marks) on the inside of a contour line. The elevation of the first depression contour is the same as the nearest regular contour line.
What are the 4 types of slopes in geography?
Slopes come in 4 different types: negative, positive, zero, and undefined.
What are the four slope elements?
Slope elements and its characteristics:
- Crest:
- Cliff:
- Talus:
- Pediment:
What is an even slope in geography?
even slope where contour lines are evenlt spaced out. Concave slope. a slope with spaced out contour lines at the beginning that get closer towards the end. Convex slope. a slope with close contour lines at the beginning and get further apart at the end.
What is a steep slope called?
A Steilhang (pl: Steilhänge) is a geoscientific term for a steep mountainside or hillside (or a part thereof), the average slope of which is greater than 1:2 or 30°.
What is a convex slope?
A terrain feature that is curved or rounded like the exterior of a sphere or circle, i.e. goes from less steep to more steep. Convex slopes generally tend to be less safe than concave slopes, but concave slopes can also avalanche.
What is a concave slope in geography?
A terrain feature that is rounded inward like the inside of a bowl, i.e. goes from more steep to less steep. Slope Shape: Slope shape makes more difference on smaller slopes than on larger ones. …
What is the difference between convex and concave slopes?
Answer: The concave slope is represented by the closely spaced contour in the upper locations and gradually become widely spaced in the lower areas. – Convex slope is a geographical feature with inconstant slopes. The upper part is less steep than the lower part.
What are finite and infinite slopes?
The term infinite slope is used to designate a constant slope of infinite extent. The long slope of the face of a mountain is an example of this type, whereas finite slopes are limited in extent. The slopes of embankments and earth dams are examples of finite slopes. The stability of a natural slope is also important.
