section 05 (quiz & script sheets & exercise videos)

Question 1

Is the following statement correct?

“The Buffer Tool can be used to create a defined distance to a physical unit.”

(L5-1)

Answer 1

TRUE

Buffers can be generated around physical units like points, lines, polygons.

Question 2

Which Tool is used to combine several shapefiles to a new shapefile?

(L5-2)

Answer 2

Merge

While merging, attributes can be chosen.

Question 3

A nationwide layer shall be reduced to one federal state. The final layer shall only contain the attributes of the input-layer.
Which Tool is used?

(L5-3)

Answer 3

Clip

Features of a layer are blended with an ancillary layer. The attributes of the input-shapefiles are equal to the attributes of the output-shapefiles.

(ancillary =untergeordnet)

Question 4

Clip and Intersect can blend two polygons.
Make 2 correct statements concerning the comparison of both.

(L5-4)

Answer 4

Clip writes only the attributes of the input-file in the new table.

Intersect writes the attributes of both files in the new table.

Question 5

Imagine there are 8 plots in an area, which are used differently by 40 inhabitants. Each plot has only one type of use, but is used by several inhabitants.
Your database consists of the inhabitants names, the type of use of its plot, the plot coordinates.

Which tool is used to keep only the type of use for further analysis?

(L5-5)

Answer 5

Dissolve

The Dissolve Tool can untie several objects with the same attribute from each other.

Question 6

Which 2 tools can be used to
combine two single polygons to one final polygon without their borders
(assuming both polygons have the same attributes)?

(L5-6)

Answer 6

Merge
The Merge Tool combines several single polygons into a new one.

Dissolve
Dissolving unites joined polygons into one.

Question 7

Is the following statement correct?

“Using the Intersect Tool, the result will only contain data from one of the input datasets.”

(L5-7)

Answer 7

WRONG

Question 8

Is the following statement correct?

“There is more than one way to get access to the different Geoprocessing Tools.”

(L5-8)

Answer 8

TRUE

Question 9

Is the following statement correct?

“With the Buffer Tool it is possible to dissolve the created buffer ares directly.”

(L5-9)

Answer 9

TRUE

Question 10

Is the following statement correct?

“Merging means the reduction of lines while Dissolving means the reduction of data.”

(Give details about Merging and Dissolving.)

(L5-10)

Answer 10

WRONG

Merging

• combines several single polygons into a new one without their borders
• (attributes can be chosen)

Dissolving
- unites joined polygons into one
- can untie several objects with the same attribute from each other
- used to keep only the type of use for further analysis
- combines two single polygons to one final polygon without their borders
(assuming both polygons have the same attributes)
