graduated symbols, graduated colours, proportional symbols, dot density

Question 6

4 ways to tie labels to features

Answer 6

placement, colour, font, line callout

Question 7

two options to store annotations

Answer 7

1. in the map - can only be used by that particular map

2. in data base - can be applied to any map

Question 8

3 types of scale

Answer 8

written, ratio, graphic

Question 9

9 map features

Answer 9

scale, title, author, map area, projection/datum, legend, north arrow, date, data source

Question 10

three types of labeling

Answer 10

dynamic, interactive, and annotation

Question 11

pro and con of dynamic labeling

Answer 11

pro: quick and easy to change features of the group
con: limited placement and modification

Question 12

pro and con of interactive labeling

Answer 12

pro: can modify the position of each label seperately
con: time consuming to label everything this way

Question 13

pro and con of annotation labeling

Answer 13

pro: most control over modification and placement
con: once converted, labels are no longer connected to attribute table

Question 14

4 steps to answering a select-by question

Answer 14

Read the question
Examine the data
Isolate out layers
Do the main selection and answer the question

Question 15

3 ways to isolate a layer

Answer 15

1. definition query
2. in attribute table; select by attributes
3. create a layer form the selected features

Question 16

4 main types of spatial relationships

Answer 16

Distance
Intersection
Containment
Adjacency

Question 17

what happens to the features in a layer when a definition query is done?

Answer 17

it isolates only those features and only those features are displayed in the layer. all other features are not shown

Question 18

how can you permanently append attributes from a non-spatial table to a spatial table?

Answer 18

First join the tables and then export the selection to a shapefile

Question 19

what type of a relationship do you need for a join and for a relate?

Answer 19

join is 1:1 and relate is 1:many cardinality

Question 20

what happens the features in a dissolve?

Answer 20

creates a new layer in which all the features of the input layer that have the same value for a specified attribute become a single feature

Question 21

what happens to the A table in a dissolve?

Answer 21

has the shape and FID columns with the combined values of the dissolved features

Question 22

what happens to the features in a clip?

Answer 22

one layer is cut using the boundaries of another layer

Question 23

what happens to the A table in a clip?

Answer 23

it will only show the attributes of the layer that was clipped but with less rows

Question 24

what happens to the features in a intersect?

Answer 24

only the area of overlap is kept and contains the features of both overlapping input layers

Question 25

what happens to the A table in a intersect?

Answer 25

that attributes and values of both input layers in the overlapping area are shown

Question 26

what happens to the features in a union?

Answer 26

even the areas on non-overlapping layers are included in the data output

Question 27

what happens to the A table in a union?

Answer 27

will result in:

• features only in the first input layer
• features only in the second input layer
• features created by areas of overlap between the two layers and will have both input layers attributes

Question 28

3 ways a buffer can be drawn

Answer 28

equadistance, variable distant, multi-ring
