What in the World?
This type of data uses a grid of cells to represent geographic data , often visualized through elevation or terrain maps.
What is raster data?
The size of a pixel that determines the area represented on the ground--zoom in too much and you get a stair-step effect.
What is spatial resolution?
This type of data is represented by points, lines, and polygons in a GIS.
What is a vector data?
These tools let users quickly highlight features to answer questions but don’t create permanent changes or processing of the data.
What are selection tools (SBA and SBL)?
This December holiday is known for gift-giving, decorated trees, and inevitable airport delays.
What is Christmas?
These essential cartographic elements should generally be included on all maps...without them your map reader may get L.O.S.T.
What are:
Legend
Orientation
Scale
Title
This is the total number of attributes a standard raster cell can store in a single-band raster dataset.
What is one?
This is a data component comprised of rows and columns, and stores non-spatial data descriptors.
What is an attribute table?
This is a method for estimating unknown values at unsampled points based on known values at nearby locations.
What is interpolation?
This Bing Crosby classic remains the best-selling single of all time.
What is “White Christmas”?
The ratio of the distance on the map that corresponds to its distance on the ground.
What is map scale?
This type of elevation model represents the bare earth, with buildings, trees, and other surface features removed.
What is a DTM?
This GIS process converts addresses or place names into spatial coordinates so they can be mapped.
What is geocoding?
This approach is generally preferred in GIS when dealing with uncertainty in spatial data or when modeling areas that don’t have crisp boundaries.
What is fuzzy logic?
This singer is unofficially known as the “Queen of Christmas,” whether she likes it or not.
Who is Mariah Carey?
These horizontal lines run east-west on a map, and their coordinate values change as you move north or south.
What is latitude?
This type of data is the key thing rasters can represent that vectors generally cannot—values that change smoothly across space.
What is continuous data?
A near archaic vector file type that has at least three different file extensions that are needed for it to work and display properly in a GIS. Still used unsurprisingly by many government GIS agencies
What is a shapefile?
This ArcGIS Pro 'tool' allows you to automate GIS workflows and easily share them with others without writing code.
What is ModelBuilder?
This 1996 song debuted on SNL - lists celebrities who celebrate Hanukkah—real or questionably real.
What is “The Chanukah Song”?
While scale bars and orientation are usually included, these elements are often unnecessary for maps that show very large areas with little detail.
What are small-scale maps?
A representation of raster data with distinct categories or classes, such as land use types or soil classifications, where each pixel holds a single, fixed value
What is discrete raster data?
This type of analysis summarizes attribute data from vector layers, letting you calculate counts, sums, or other statistics for features that overlap or fall within other boundaries.
What is summary statistics (vector-based)?
This geographic principle states that everything is related, but things closer together are more related than things farther apart, forming the basis for interpolation and spatial correlation.
What is Tobler’s First Law of Geography?
In Japan, this unusual Christmas tradition—was popularized by a 1970s ad campaign to eat this food.
What is eating KFC for Christmas?
