Geography and Remote Sensing: Key Concepts and Technologies

True or false: displacement can lead to long-term lower-income residence

False

Population pyramid

it applies high birthplaces and low birthrate.

Potential source of GPS error

# of satellites, interference, range error, signal slowdown, buildings, mountains, clock bias, inaccurate receiver.

Web mapping

a static map that can be published on the web.

Functions for boolean analysis

and, or, not.

Why do climate scientists map temp anomalies over absolute temperatures?

Things vary from place to place.

Primary advantage for color imagery

Vegetation.

Passive sensors

They use less energy and are more accurate compared to normal sensors, and use the reflection from the earth.

Human geography

How humans interact with shape and influenced by spatial organization of places.

Minimum number of satellites for GPS signal

3.

Sources for VGI

Bird count, Facebook, Twitter, eBird, Strava, social media, iNaturalist.

Remote sensing

Obtaining info from a location via remote method, using electromagnetic waves.

True or False: Climate change rate and planet warming are the same rate.

False

What does GPS stand for?

Global positioning system.

Demographics

Socioeconomic groups that differ in gender, age, race

Remote sensing applications

glaciers, vegetation, wildfires, anything that changes over time.

3 V's of big data

volume, velocity, and variety.

GPS operation country

The US.

What does VGI stand for?

Voluntary geographic information.

Spatial arrangement types

random, clustered, and dispersed.

Segments of GPS

satellite, receiver, control.

Urban heat island effect

Concrete buildings get hotter faster.

Geostationary satellite

A satellite that is fixed in the sky

Big data

Data that is so big that most of our software is inaccurate.
