If the data's CRS is WGS 1984, can we compute for a polygon's area (i.e. sqm, ha, sqkm)?
No
Sometimes
Yes
Maybe
The default units of measurement if the data is projected in UTM is
meters
degrees
feet
inches

PRS 1992
Luzon 1911
UTM zone 51N
UTM zone 48N
In UTM coordinate system, the Northing is referenced from
Prime Meridian
Equator
Apparels
Parallels
In UTM, the reference for the Easting is the False Central Meridian (FCM) which is valued at:
0 meter
300,000 meters
10,000,000 meters
500,000 meters
In WGS 1984 (a type of GCS), the "zero Longitude" is:
Prime Meridian
Equator
False Central Meridian
UTM 51N
In the Philippines, the projected CRS that we use is:
WGS 1884 UTM zone 51N
WCS 1884 UTM zone 51N
WGS 1984 UTM zone 51N
WGS 1994 UTM zone 51N
In GIS, what does the acronym UTM mean?
Universal Motion Dancers
Universal Traversal Mercator
Universal Traverse Mercator
Universal Transverse Mercator
If the pair of coordinates is Longitude and Latitude, it implies that the CRS of the data is
Projected
Geographic
Protected
UTM
If the pair of coordinates is Northing and Easting, it implies that the CRS of the data is
WGS 1984 (GCS)
Geographic (Long Lat)
PRS 1992 (Long Lat)
Projected / UTM
What does GIS mean?
Geographical Information System

Remote sensing is the process of collecting data without physical contact to the target
TRUE
FALSE
This represents the size of one pixel on the ground --- usually described in centimeters per pixel (cm / px)
Generated Samples for Drone
Ground Sampling Distance
Ground Surface Distance
General Sampling Distance
In photogrammetry and aerial surveying, ground sample distance (GSD) can affect the accuracy of your survey.
TRUE
FALSE
These are points on the ground with known coordinates. Points are usually marked by painted patterns or steel sheets established on the ground. These points will serve as tie points during survey data processing.
General Control Points
Ground Central Points
Ground Control Points
Ground Control for Photos
The software we use for Photogrammetry
Agisoft Metashape
QGIS
Google Earth
GeoSetter
length of time the camera shutter is open, exposing light onto the sensor, a.k.a. how long your camera spends taking a photo. Usual values are 1/1000, 1/100/ 1/600 etc.
Shutter speed
ISO
Aperture
Focus
camera setting that brightens or darkens a photo. High number means brighter which helps you capture images in darker environments. Values are around 100 to 6400.
Shutter speed
ISO
Aperture
Focus
opening of a lens's diaphragm through which light passes. Calibrated in f/stops and generally written in numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16.
Shutter speed
ISO
Aperture
Focus
The maximum recommended flying height for drones (as allowed by law):
500 meters (1,640 feet)
120 meters (400 feet)
50 meters (164 feet)
No limits
Photogrammetry software can only handle geotagged images. Agisoft Metashape can only recognize photographs that have GPS coordinates.
False.
True.
Using spaces in filenames and folder names is not advisable. Which should be used instead of spaces?
use underscore
use dash
no separation between words
Camel Case
it's okay to use space in filenames
The International Standard for the representation of dates and times:
ISO 14344
ISO 3166-PH
ISO 8601
ISO 456
Executive Order No. 321 series of 2004 prescribes the adoption of _________________ as the standard reference system of surveys in the Philippines
