Term
| What are the different types of map projections and what is a Mercader map used for? |
|
Definition
| Conformal - Angular measurements, Equal-area - Regions in correct relative size, Equadistant - Maintains distance along great circles from one or two pts, Azimulthan - direction from one central pt. Mercator is used for keeping angles |

Term
| Define Scale and which is best for making a map of the globe |
|
Definition
| Scale is a ratio of two numbers. It has no units because it is a ratio and if the ratio is 1:10 then 1inch would - 10inches. a large scale (1:50k+) would be best for the globe |
|
|
Term
| What are topograhpic maps and why do we make them |
|
Definition
| It is a map that shows elevations of a certain area. We use them so we can navigate hilly/mountainous area and plot what path to take |
|
|
Term
| in accordance with electromagnetic spectrum, what does wavelength mean? |
|
Definition
| It is the distance between the peaks or valleys of a wave. |
|
|
Term
| What interval of e- radiation are in the visible spectrum |
|
Definition
|
|
Term
| What portions of e- spectrum are typically used for remote sensing |
|
Definition
|
|
Term
| When e- radiation hits a surface it usually does 3 things |
|
Definition
| Absorbs, Reflects, Refracts |
|
|
Term
| Which platform has never been used for remote sensing |
|
Definition
|
|
Term
| What is the difference between active and passive sensing |
|
Definition
| Active is when something is transmitted from the sensor while passive uses the natural wavelengths from the sun |
|
|
Term
| What is planimetric shift? |
|
Definition
| It's when an object appears above or below the base image |
|
|
Term
|
Definition
| corrected photo so that it is a map and you can actually measure distances on it |
|
|
Term
| What are the typical reflectance curves for soil, vegetation, and water |
|
Definition
| Water reflects very little in the visible are but then drops off completely in the NIR zone and IR. Vegetation reflects mainly in the green part of the visual spectrum while reflects about 50% of the NIR and IR. Soil has an odd curve reflecting a moderate amount over all of it |
|
|
Term
| What is atmospheric correction? |
|
Definition
| It's the corrections we make to a reading to account for the particles in the atmosphere that distort the signals that are being read from our instraments |
|
|
Term
| What are descriptive Stats? |
|
Definition
| Statistics that describe a certain set of inputs |
|
|
Term
| Why do we make false colors and what are they? |
|
Definition
| We change the colors of a certain set of wavelengths to show a particular feature on a map. i.e. making vegetation pink to distinguish it from everything around it |
|
|
Term
| Know the different classifications (supervised and unsupervised) |
|
Definition
| Supervised is when a reading is there to edit it in a meaningful way such as making all the old forrest a different color from the new forrest. unsupervised does this by coloring the different wavelengths different colors but is seldom useful |
|
|
Term
| What do we use time series for? |
|
Definition
| To make maps that show things like deforestation. |
