2024-2025
Layers are groups of geographic objects that seem similar and may have
features and surfaces.
features - A polygon, line, or point. Geographic things in a layer. Vector data
surfaces - A measured value for any specific location on the earth's surface.
Raster data. Example: slope, temperature, rainfall.
attributes - ANSWER located in the attribute table, links features and their
attributes to ask inquiries about the information.
Scale is the link between the size of features on a map and the size of the
corresponding locations in the globe.
Spatial Relationships - ANSWER compares locations based on feature
coordinates. For example, how close or far
Thematic maps use colours or other symbols to indicate features' qualities.
ArcMap - ANSWER the application for creating maps and analysing data
ArcCatalog - ANSWER data man
agement app
Geodatabase - ANSWER contains several various items, including feature
classes, networks, tables, and rasters.
Feature class - ANSWER a collection of similar objects
, layer file - ANSWER refers to a feature class and keeps information about its
attributes and display settings. will generate the exact same symbols and look
when saved here.
shapefile - ANSWER old data contains a feature class.
nominal data: ANSWER names or uniquely recognized items.
example: state names, owner of parcel
single symbol map - ANSWER all characteristics are displayed with the same
label.
categorical data - ANSWER divides features into a specific number of separate
categories.
- textual or numerical
- a distinct icon for each category
Unique values map - ANSWER distinct symbol for each category or value
ordinal data: ANSWER ranks categories on an arbitrary scale.
example of a graduated color map
can be displayed using a symbol, size, or color
interval data - ANSWER values arranged on a regular numerical scale
example: temperature, pH
- Must be separated into classes prior to mapping.
