Question 11

A type of projection where longitudes are equal but latitudes are not. It has increasing shape and scale distortions toward the poles.

Answer 11

Cylindrical Projection

Question 12

A cylindrical map projection originally presented in 1569 to display accurate compass bearings for sea travel. Its longitudes are parallel and equal spacing between 15°. Best used for large scale mapping near equator. Developed by who?

Answer 12

Mercator; Gerardus Mercator

Question 13

Spherical projection based on the Mercator by Johann Lambert in 1772. Best used for north-south oriented areas.

Answer 13

Transverse Mercator

Question 14

A plane coordinate grid system, which consists of 60 longitudinal zones in the northern and southern hemisphere, equally spaced with 6° in between. It uses meters instead of DMS.

Answer 14

Universal Transverse Mercator

Question 15

A local plane coordinate grid system that is primarily used for collecting survey data for the Philippines. Divides the Philippines into 5 zones from 116° to 126°

Answer 15

Philippine Transverse Mercator (PTM)

Question 16

The science of measuring the geometric dimensions of the Earth.

Answer 16

Geodesy

Question 17

A commonly used worldwide datum developed from satellite measurements on the surface of the Earth. Unlike most datums, its origin is the center of the Earth. GPS and Google Earth uses this.

Answer 17

World Geodetic System 1984

Question 18

A localized datum commonly used in the Philippines, and references the Clarke 1866 ellipsoid, with its origin located at Hinanggayon, Marinduque at 13°33’41.00” N, 121°52’03.33” E from the Greenwich Meridian.

Answer 18

Luzon Datum 1911

Question 19

An updated and adjusted version of the Luzon Datum 1911 and derived from the Philippine Transverse Mercator. Most of the generated maps in NAMRIA and other government agencies utilize this as the primary projection. It divides the Philippines into 5 zones.

Answer 19

Philippine Reference System 1992

Question 20

What is NAMRIA?

Answer 20

Philippines National Mapping and Resource Information Authority

Question 21

A type of satellite orbit where the satellite is stationed in place along the equator and revolves around the Earth in sync with the Earth’s rotation.

Answer 21

Geostationary orbit

Question 22

A type of satellite orbit that is not stationed in the Earth’s equator but is tilted with respect to the Equator’s plane.

Answer 22

Geosynchronous orbit

Question 23

A type of satellite orbit that travels around the poles, across the globe, traversing the whole surface of the Earth in a spiral-like course.

Answer 23

Sun-synchronous orbit

Question 24

The most recent Landsat satellite that launched last September 27, 2022. A joint effort of NASA and USGS which aims to continue it’s predecessor’s goal to observe and collect remote sensing images of global land cover for different applications and uses.

Answer 24

Landsat 9

Question 25

Passive vs Active Sensor System

Answer 25

Passive - sensor relies on an external source to produce reflected light for it to receive

Active - has an internal source which transmits light and to be reflected back to the sensor

Question 26

A remote sensing method that utilizes an active light sensor which can measure ground height and generate a 3-dimensional model of the image of the surface that also contains its geographic information

Answer 26

Light Detection and Ranging (LIDAR)

Question 27

A remote sensing method that utilizes an active sensor transmitting radio waves used to detect objects on the ground or in the atmosphere

Answer 27

Radio Detection and Ranging (RADAR)

Question 28

A remote sensing method utilizing radar images to generate 3d images of the surfaces of the Earth

Answer 28

Interferometric Synthetic Aperture Radar (InSAR or IFSAR)

Question 29

A remote sensing method typically used underwater which measures acoustic signal or sound pulses as it bounces back “echoes” from objects which can be interpreted by a transducer and generate 2d image of the area.

Answer 29

Sound Navigation and Ranging (SONAR)
