GIS Basics
These allow the user to quickly return to a previous map extent or zoom.
What is a bookmark?
This part of the attribute table holds the data for each record related to a single attribute.
What is a field or column?
This kind of vector feature can be used to represent tracts, fields, and parcels.
What is a polygon?
This data model represents spatial features as points, lines, and polygons.
What is the vector or feature data model?
This tool is used when selecting features by their location or proximity.
What is the "select by location" tool?
This is the measure of accuracy when discussing raster data sets; the size of each cell or pixel.
What is resolution?
This function can be used to determine the area of each feature in an attribute table.
What is "calculate geometry"?
The relationships among geographic objects, regardless of how they are stretched or warped.
This data model represents spatial data as a grid of cells or pixels, arranged as rows and columns.
What is the raster data model?
This tool Creates polygons around input features to a specified distance.
What is the "buffer" tool?
This is the tab or menu where users can change the appearance of a layer.
What is "symbology"?
"Kolligian Library" is an example of this type of attribute measurement.
What is a nominal attribute measure?
The spatial relationship among objects that share a common edge.
What is adjacenecy?
This is the other name for text data.
What is "string"?
This overlay tool eliminates all vector features other than the ones that overlap.
What is the "intersect" tool?
When sharing a shapefile, these are the minimally required files that should be included.
What are the .shp, .dbf, and .shx files? (Also .prj!)
An attribute field that is common to more than one table that enables a join or relate operation.
What is a key?
This tool can be used to fix topology errors such as dangling nodes, gaps, and overlaps.
This data type is represented by whole numbers.
What is an integer?
This tool aggregates features based on specified attributes.
What is the "dissolve" tool?
A purplish hue that is difficult to find within the symbology properties menu.
What is Cattleya orchid ?
This practice reduces redundancy and increased the ability of a table to be queried.
What is database normalization?
These are the rules when validating the topology of line features.
What are "must not have dangles, "must not overlap", "must not intersect"?
This data type that can hold the largest fractional values.
What is double?
This overlay tool preserves the base layer in addition to any vector polygons that overlap with the base layer but remove anything not overlapping.
What is the "identity" tool?
