Term
 Precision.
Definition
 Refers to measurements
Term
 Accuracy.
Definition
 Refers to error.
Term
 CE.
Definition
 Circular error is the geospatial position horizontal accuracy expressed in feet or meters at 90% probability.
Term
 LE.
Definition
 Linear error is the geospatial position vertical accuracy expressed in feet or meters at 90% probability.
Term
 CE. and LE.
Definition
 Should be reported at 90% for targeting.
Term
 Combined CE. and LE.
Definition
 Determine the TLE.
Term
 TLE.
Definition
 Target location error is the difference between the actual an express location of a target. TLE error is intrinsic to the sensor.
Term
 CEP is circular error probable.
Definition
 - The geospatial horizontal accuracy expressed in feet or meters at 50% probability.- CEP error is intrinsic to the weapons systems.
Term
 HAE is:
Definition
 - Height above ellipsoid is the distance above or below on the 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 3930 mile radius from that point out to the 45° latitude lines
Term
 MSL:
Definition
 - Mean Sea Level is a title 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.
Term
 The CE and and LE category 1 standard for targeting is:
Definition
 6 m or 20 feet.
Term
 Geotrans is a NGA validated program that allows:
Definition
 Converting geographic coordinates among a wide variety of coordinate systems, map projections, and Datums.
Term
 Datum:
Definition
 A base reference for a coordinate system used to model the earth; there are two categories of a datum, horizontal and vertical.
Term
 The vertical datum that is native to DPPDB is:
Definition
 EGM 96.
Term
 Photogrammetry is:
Definition
 The art and science of making measurements from photographs/imagery.
Term
 The basic types of imagery are:
Definition
 Electro – optical, infra – red and synthetic aperture.
Term
 The current imagery sources (platforms) that can generate imagery used by the military are:
Definition
 National technical means, the air breather theater systems, predator, IGNAT, shadow, Global hock, P– 3 Orion, U2 dragon lady, E-8JSTARS, scan eagle.
Term
Definition
 -Metadata allows the community to search and archive imagery.- it also interfaces with other applications in Geo positioning- most importantly, it provides Geo coordinates
Term
 What impact does light, shadow and image angle/obliqueness have on target marker placement and ensure you state why each is important:
Definition
 -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.
Term
 Mono imagery and stereo imagery:
Definition
 -Mono imagery is a 2D representation of a 3D world.- Stereo imagery uses multiple image captures of the same area and allows us to look at the same thing from two different angles.
Term
 Image obliquity:
Definition
 The difference between the reference elevation and the actual terrain elevation creating a possible horizontal error.
Term
 Sensor location, altitude, look into platform/sensor accuracy and ground track:
Definition
 Are all error sources for image obliquity.
Term
 Key features or characteristics to properly employ terrain recognition are:
Definition
 North arrow orientation, look angle, lakes and rivers, roads and paths, structures and buildings, vegetation and soil patterns, light and shadow.
Term
 It is important that you have all of the current digital point positioning database DPPDB for your area of operation and:
Definition
 Purge obsolete DPPDB for accuracy and currency of the imagery.
Term
 The typical data size for 1 DPPDB volume is:
Definition
 4.2 gigabytes
Term
 A DPPDB image covers:
Definition
 60 nautical miles by 60 nautical miles
Term
 You would use a segment that has a higher (decreased accuracy) CE and LE when:
Definition
 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.
Term
 The national geospatial intelligence agency maintains an post:
Definition
 The global holdings list and DPPDB.
Term
 The combatant commander for there a AOR maintains the:
Definition
 No strike list.
Term
 When importing the global holdings list text file onto your computer or server it should:
Definition
 Be placed in the images/DPPDB folder on your computer or server.
Term
 A PFI is a 3D template, correlated from DPPDB stereo reference imagery and a single national image transmission format (NITF) file. PFI files are also:
Definition
 NGA validated and approved for targeting with circular error, linear error terms.
Term
 The following application support PFI files:
Definition
 PFED, DPSS scene matching, handheld sync (HHS), PFIG, DIEE, PFI viewer – handheld (PFIV–H), and NITF viewer.
Term
 CJCSI 3505.01B mandates individuals who:
Definition
 Derive coordinates used in the employment of coordinate seeking weapons be certified by NGA or an NGA accredited service, Geographic combatant command/functional command (GCC/FCC) or allied program.
Term
 TC 3–09.61 is the Army CONOPS that defines the training and certification standards and:
Definition
 Procedures for the Army precision fires target coordinate mensuration TCM program.
