Question 1

Precision refers to

Answer 1

measurements

Question 2

accuracy refers to?

Answer 2

error

Question 3

CE (Circular Error) is?

Answer 3

The geospatial position horizontal accuracy expressed in feet or meters at 90% probability

Question 4

LE (Linear Error) is?

Answer 4

The geospatial position vertical accuracy expressed in feet or meters at 90% probability

Question 5

CE and LE should be reported at ?

Answer 5

90% for targeting

Question 6

Combined CE and LE determine the?

Answer 6

TLE

Question 7

TLE (Target Location Error)

Answer 7

is the difference between the actual and expressed location of a target, TLE is intrinsic to the senser

Question 8

HAE (Height Above Ellipsoid)

Answer 8

is the distance above or below an ellipse with a mathematically defined regular surface used to express a geometric model of the Earth
It was derived by using satellites to find the exact center of the Earth and creating an ellipse, a 3,930 mile radius from that point out to the 45 degree latitude lines.

Question 9

MSL (Mean Sea Level)

Answer 9

Is a tidal datum that is arithmetic mean of hourly elevation observed over a specified 19 year cycle
It averages out tidal highs and lows caused by the changing effects of the gravitational forces of the sun and moon

Question 10

The CE and LE category 1 standard for targeting is

Answer 10

6 m or 20 ft.

Question 11

CEP (Circular Error Probable)

Answer 11

The geospatial horizontal accuracy expressed in feet or meters at 50% probability
CEP is intrinsic to the weapons system

Question 12

GEOTRANS is?

Answer 12

A NCA validated program that allows converting geographic coordinates among a wide variety of coordinate systems, map projections, and datums

Question 13

Datum?

Answer 13

A base reference for a coordinate system used to model the earth; there are two categories of a datum, Horizontal and Vertical

Question 14

The vertical datum that is native to DPPDB is?

Answer 14

EGM 96

Question 15

Photogrammetry is the ?

Answer 15

Art and science of making measurements from photographs / imagery

Question 16

The basic types of imagery are?

Answer 16

Electro-Opitcal, Infra-Red and Synthetic Aperture Radar

Question 17

The current imagery sources that can generate imagery used by the military are?

Answer 17

National technical means and the air breather theater systems:
Predator, IGNAT, Shadow, Global Hawk, P-3 Orion, U-2 Dragon Lady, E-8 JSTARS and Scan Eagle

Question 18

Metadata?

Answer 18

Metadata allows the community to search and archive imagery
It also interfaces with other applications in geo-positioning
Most importantly, it provides geo-coordinates

Question 19

What impact does light, shadow and image angle/obliqueness have on target marker placement and why

Answer 19

Obliquity and error can skew the coordinates of an image increasing the search time in terrain recognition.
In mountainous terrain, adverse look angle and obliquity can be challenging.
Shadows can help identify what you are looking at. Washout (too much light) can inhibit image resolution.

Question 20

Mono Imagery and Stereo Imagery

Answer 20

Mono Imagery is a 2-D representation of a 3-D world
Stereo Imagery uses multiple image captures of the same area and allows us to look at the same thing from two different angles.
Stereo Imagery allows us to accurately determine feature height.

Question 21

Image Obliquity

Answer 21

The difference between the reference elevation and the actual terrain elevation creating a possible horizontal error

Question 22

Sensor location, altitude, look angle platform/ sensor accuracy and ground track are all ?

Answer 22

error sources for image obliquity

Question 23

Key features or characteristics to properly employ terrain recognition are?

Answer 23

North arrow orientation, look angle, lakes and rivers, roads and paths, structures and buildings, vegetation and soil patterns, light and shadow

Question 24

What is important to do in order for accuracy and currency of the imagery

Answer 24

have all of the current DPPDB for your area of operation and purge obsolete DPPDB

Question 25

The typical data size for one DPPDB volume is?

Answer 25

4.26 GB

Question 26

A DPPDB Image covers?

Answer 26

60 nm X 60 nm

Question 27

You would use a segment that has a higher CE and LE when?

Answer 27

The feature you are looking for is not on the current segment,
Has a raster burn through it
Or unit SOP or COCOM dictate which ones to use

Question 28

The National Geospatial-Intelligence Agency (NGA)

Answer 28

Maintains and posts the Global Holdings List and DPPDB

Question 29

The Combatant Commander for the AOR maintains the?

Answer 29

No Strike List

Question 30

When importing the Global Holdings List text file on to your computer or server, it should be placed in ?

Answer 30

the Images/DPPDB folder on your computer or server

Question 31

A PFI is a digital file consisting of?

Answer 31

A 3-D template, correlated from DPPDB stereo refernce imagery and a single national image transmission format (NITF) file. PFI field are also NGA validated and approved for targeting with CE and LE terms
