Geocoding refers to the process of converting text-based postal address data into digital geographic coordinates.

Address geocoding interpolates the location of a street address by comparing it with data in the reference database.

Which of the following is true about Geocoding? (select all that apply)

Parsing converts the Address to lower case

Which of the following is required to effectively geocode? (select all that apply)

Addresses to be matched are parsed into separate components

Which of the following geocoding styles locates street address on both sides of the street using a line reference layer and requires address ranges on both left and right side of the street?

Which of the following geocoding styles locates street address without considering left or right sides and requires a single address range for each street?

Which of the following geocoding styles locates street address by matching a single field address to a single point or polygon?

Which of the following geocoding styles is most often used with parcel data?

Which of the following geocoding styles matches two fields containing a city name and a state name or abbreviation?

Place the following Geocoding steps in order [blank_start]3[blank_end] Match the address in batch mode [blank_start]2[blank_end] Choose the address table and set up the session [blank_start]1[blank_end] Add the address locator previously created [blank_start]4[blank_end] Review the matched/unmatched addresses [blank_start]5[blank_end] Change the geocoding options to facilitate matching [blank_start]6[blank_end] Rematch addresses in batch or interactive mode

For crime mapping and analysis, one researcher has stated that a ____ hit rate is unacceptable and another has derived statistically a minimum acceptable hit rate of ____.

A geocoding rate of 95% or better is required for competitive location-based services

To bring the rate to 95% or better a current and accurate reference database and additional effort in validating street addresses would be required

Positional accuracy effects the quality of geocoding

Which of the following is commonly used in Traffic Accident Police Reporting?

Which of the following assigns addresses to points?

Which of the following could be factors that could effect the accuracy of geocoding? (select all that apply)

Geocoding provides a convenient “out of the box” method for municipalities to convert address-referenced data to a GIS format and can be depended upon when high accuracy is important

Dynamic segmentation can be defined as the process of dynamically computing the location of events along a route

A route is a linear feature with a linear measurement system stored with its geometry

In ArcGIS 'Events' are linearly referenced data that occur along routes

Which of the following describes a route that follows one direction

Which of the following describes a route that is joined with another route?

Which of the following describes a route that subdivides into two routes?

Which of the following describes a route that intersects itself?

Which of the following are examples of linear events? (select all that apply)

Which of the following are examples of point events? (select all that apply)
