correct answer ✅Flat: fewer, large triangles
Steep: more, small triangles
TINs consist of -
correct answer ✅Points, lines, polygons
TINs: Geometric Objects -
correct answer ✅Triangles - faces
Points - nodes
Lines - edges
Raster data storage -
correct answer ✅Arrays are a computers best friend
-compression
Grid of cells/pixels

-Attribute data (quantitative)
Raster Information -
correct answer ✅All rasters have:
-number of columns and rows (integers)
-cell size (resolution)
-type (integer, floating point precision)
-extent - lower left coordinates (x,y) or Top, Bottom, Right, and Left
coordinates
Raster Data Model -
correct answer ✅A raster is a cell-based data structure composed
of rows and columns for storing images
-cells are square
-cells are homogenous
-cells are also called 'pixels'
-cells are all same size (resolution)
Raster Data Storage -
correct answer ✅Stores attribute values can represent quantities
or qualities

Raster Data Model Elements -
correct answer ✅Cell values
Cell size
Bands
Spatial reference
Raster Data Model: Cell Value -
correct answer ✅Integer, Float, NoData, etc.
Raster Data Storage: Cell Size -
correct answer ✅Cell Size (spatial resolution)
Cell size=length of one side of a cell in the real world
Higher (finer) vs. lower (coarser) spatial resolution
Spatial Resolution -
correct answer ✅Resolution=Size of each cell
-Ex. 10m res. Means each cell represents a 10x10m square of the
earth

Raster Data Model: Bands -
correct answer ✅Think of a stack
RGB- digital cameras
Multi-band
Mixed Pixel Problem -
correct answer ✅In remote sensing, a pixel whose digital number
represents the average of several spectral classes within the area
that it covers on the ground, each emitted or reflected by a
different type of material. Mixed pixels are common along the
edges of features.
Raster Data Model: Spatial Reference -
correct answer ✅Bottom-left Cell is start point
Referenced by center of cell
Inherent location
Raster Data Model: Types of datasets -
correct answer ✅-Satellite Imagery: Landsat, MODIS
-Aerial Imagery: Aircraft, USVs
-DEMs: USGS, LiDAR
