working with vector data

Question 1

nodes

Answer 1

endpoints of lines

Question 2

vertex

Answer 2

an x,y pair

Question 3

multipart feature

Answer 3

a single feature made up of several unconnected parts

Question 4

FID

Answer 4

a unique integer used to link a feature to its attribute data

Question 5

feature class

Answer 5

a collection of similar features stored together as a dataset including spatial objects and attributes, containing only 1 type of geometry

Question 6

shape file

Answer 6

a feature class that is not stored in a geodatabase

Question 7

topological models

Answer 7

stored with feature classes, stores spatial relationships between features, can be used to find data errors

Question 8

queries

Answer 8

extract data using attribute fields or spatial relationships

Question 9

clip

Answer 9

extracts features within a bounding polygon

Question 10

erase

Answer 10

opposite of a clip, extracts data outside of a bounding polygon

Question 11

merge

Answer 11

combines all features from 2 or more datasets into a single feature class

Question 12

dissolve

Answer 12

removes boundaries of features with the same value in the specified fields

Question 13

generalize

Answer 13

used to remove vertices to simplify a shape

Question 14

metadata

Answer 14

information on the source and constraints of a dataset, should be consulted before using data

Question 15

import and export

Answer 15

moves data in and out of geodatabases, allows the use of tools and filters
