1.

Process of assigning geospatial positioning information to raster data based

What process is this?

a)

Georeferencing

b)

Geographic Information System

c)

Global Positioning System

d)

Geographical mapping data

2.

What does georeferencing generates?

a)

Associate coordinate information for the map image

b)

Generated image that does not have coordinate

c)

Saves a digital image of the map

d)

Scan map coordinate information to computer

3.

This data obtained by scanning maps or collecting aerial photographs. What data is this?

a)

Georeferencing data

b)

Coordinates data

c)

Image Raster Data

d)

Raster Data

4.

What do you need to do before use it for raster datasets in conjunction with the other spatial data?

a)

Need to identify the coordinate raster datasets before conjunction

b)

Need to align them to a map coordinate system

c)

Define using raster data

d)

Need to use map projection to georeferencing

5.

"Used to build a polynomial transformation that will shift the raster dataset from its existing location to the spatially correct location."

a)

Dataset

b)

Coordinating System

c)

Raster dataset

d)

Control points

6.

How many numbers of links you need to create in georeferencing?

a)

Scanned map datasets don't normally contain links of spatial reference information

b)

Depends on the complexity of the transformation you plan to use to transform the raster dataset to map coordinates.

c)

Essentially associating data with a specific area on Earth

d)

The process involves identifying a series of ground control points known x,y coordinates

7.

Similar to georeferencing, this feature aligns an input dataset to a reference dataset, based on links between common control points. Name “this feature”

a)

Spatial adjustment

b)

Raster Dataset

c)

Output Dataset

d)

Geoprocessing

8.

What is the major differences between georeferencing and spatial adjustment?

a)

The method of georeferencing features having the different attributes are searched and spatial adjustment found the spatial boundary dropped.

b)

The georeferencing of the combined coverage will have the attributes of both but not the input coverages

c)

The features within the common area of both coverages is preserved

d)

Georeferencing is used to re-create a missing or unknown spatial reference for raster and CAD data, spatial adjustment is used to correct the alignment of editable vector data.

9.

What type of data that can be spatially adjusted?

a)

Data set

b)

Shape files

c)

Output dataset

d)

Geoprocessing

10.

Spatial adjustment methods are used in?

a)

Edit session

b)

Raster Dataset

c)

Qgis

d)

Input Dataset

11.

Which one is a method for performing spatial adjustment?

a)

Vector data , raster data and tabular and attribute table

b)

Transformation , Tabular Data , and Vector Data

c)

Raster Data , Attribute Data , Transformation Data and Rubber Sheeting

d)

Transformation, edge matching, and rubber sheeting.

12.

…… spatial adjustment method that is typically used for connecting the endpoints of features with each other.

a)

Irregular data

b)

Endpoints Linking

c)

Edge matching

d)
