Geotech exam 2 questions with correct
answers
Geographic scale - ** VERIFIED ANSWERS **✔✔the real-world size or extent of an area.
Map scale - ** VERIFIED ANSWERS **✔✔a metric used to determine the relationship between
measurements on a map and their real-world equivalents.
Large-scale map - ** VERIFIED ANSWERS **✔✔a map with a higher value for its representative
fraction, such maps usually show a smaller geographic area.
Small-scale map - ** VERIFIED ANSWERS **✔✔a map with a lower value for its representative
fraction; such maps usually show a larger geographic area.
Reference map - ** VERIFIED ANSWERS **✔✔a map that serves to show the locations of features
rather than thematic information.
Thematic map - ** VERIFIED ANSWERS **✔✔a map that displays a particular theme/feature.
PPI - ** VERIFIED ANSWERS **✔✔pixels per inch - digital image resolution on computer monitor.
Higher PPI means higher resolution and better quality of digital images.
DPI - ** VERIFIED ANSWERS **✔✔Dots (of ink) per inch on a printed image. (printer resolution).
More dots means higher print quality.
Pixel dimension - ** VERIFIED ANSWERS **✔✔how many pixels the image is made up of in height
and width.
Digital image size - ** VERIFIED ANSWERS **✔✔the size in inches of your digital image.
, Color depth - ** VERIFIED ANSWERS **✔✔also know as bit depth - the number of bits used to
indicate the color of a single pixel.
JPEG - ** VERIFIED ANSWERS **✔✔Joint photographic experts group; an image or graphic file
format.
TIFF - ** VERIFIED ANSWERS **✔✔Tagged image file format; file format used for graphics on
images.
PNG - ** VERIFIED ANSWERS **✔✔portable network graphics; raster image type that can have a
transparent background.
GIF - ** VERIFIED ANSWERS **✔✔graphic interchange format; for simple web graphics that do
not have gradients or natural shades or do not have many colors.
BMP - ** VERIFIED ANSWERS **✔✔bitmap; a standard developed by microsoft
Network - ** VERIFIED ANSWERS **✔✔a series of junctions and edges connected together for
modeling concepts such as streets. Made of junctions, edges, and connectivity.
Junction - ** VERIFIED ANSWERS **✔✔a term used for the nodes (or places where edges come
together) in a network.
Edge - ** VERIFIED ANSWERS **✔✔a term used for the links of a network.
Connectivity - ** VERIFIED ANSWERS **✔✔the linkages between edges and junctions of a
network.
Geometric network - ** VERIFIED ANSWERS **✔✔the agent in the network cannot choose travel
direction. Path is determined by external forces such as gravity, water pressure. Usually one-
direction travel.
