Join me at the table please
This is a data component comprised of rows and columns, and stores non-spatial data descriptors.
What is an attribute table?
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 type of data is represented by points, lines, and polygons in a GIS.
What is vector data?
This geoprocessing tool lets you extract the shape of one layer (the dough) using another layer as a boundary (cookie cutter)
What is the clip tool?
This three-letter acronym stands for the computer system used to capture, store, check, and display data related to positions on Earth’s surface.
What is GIS (Geographic Information Systems)?
In an attribute table, these contain one type of information, such as population, name, or area.
What are fields/columns?
This type of map uses different colors or shades to show how a value varies across geographic areas such as counties or states.
What is a choropleth map?
This is the name of the manual process where a user traces features from an aerial photo or paper map using a mouse to create new vector data.
What is Digitizing?
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)?
While a paper map is static, this type of map allows you to pan around, zoom in and out, and click on features to see pop-up information on a screen.
What is a Interactive Map (or Web Map)?
In a standard GIS attribute table, this is what each individual row represents
What is an individual Feature (or Record)?
The ratio of the distance on the map that corresponds to its distance on the ground.
What is map scale?
You want to know the area of every polygon in your layer. This ArcGIS Pro tool can calculate that information directly from the feature's shape.
What is Calculate Geometry?
You run a geoprocessing tool and get fewer features than expected. Before blaming the tool, check whether you had one of these active on your input layer.
What is a selection?
These horizontal lines run east-west on a map, and their coordinate values change as you move north or south.
What is latitude?
A county's name can change or be spelled differently between datasets, so this type of identifier is often better for joining tables.
What is a Geocode (Geoid, FIPS, etc code)?
You want your mapped features to be the "figure" and the surrounding area to recede into the "ground." This visual principle can help you accomplish that.
What is contrast?
A great place to store your GIS data and tables for your project. Its also where you create brand new points, lines, or polygons from scratch
What is a geodatabase?
Before calculating the area of a polygon, you should pay attention to this because it determines the units and can affect the accuracy of the measurement.
What is the coordinate system?
The choice spatial reference system to use for a project at the city or county scale with measurements in feet or meters
What is a State Plane Coordinate System (or Projected Coordinate System)?
You try to join two tables, but the join results in all <NULL>. Your probably have a mismatch in these.
What is field data types and/or lengths (or contents)?
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 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 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 summarize within?
This standard unit of measurement is used by world coordinate systems like latitude and longitude to measure the angular curves of the Earth (name all components).
What is Degrees, Minutes, and Seconds (DMS)?
