A range of colors indicates a progression of attribute values. Colors can vary in intensity, range, or both

A Proportional Symbol Map where map symbols change in size as the do the values they represent so that different sizes of symbol show different quantities is also known as a __________________.

Thematic map where quantitative measures found in the attributes are displayed in equal intensity points randomly within the represented area. Shows intensity of a value within a geographic area

A method of sorting, arranging, and determining the various classifications that attribute data can be divided into for purposes of display and analysis without use of computer algorithms. Often symbols for these classifications are explained in a map key

Attribute data set that is classified into categories of equal size; often divided by another attribute to normalize selected characteristic being displayed.

A set of categories for data classification that divide the range of all values into distinct and equal, but not overlapping, intervals ; sometimes called class intervals

Classification scheme where a class of values is divided into equal parts

A manual method of classification where ‘natural’ or apparent breaks in the data set define the classes. Data histograms show natural breaks at low points, ‘valleys’, in the data set.

A classification method where the interval is determined by class intervals on a geometric series (such as nested circles/ squares or radiating lines)

Statistical classification method using the average deviation from the mean of a set of values to set classification points in data sets

A graph showing the distribution of values within a set of data.

The process of dividing numeric values by other numeric values to minimize quantitative differences between areas or populations. Example: Comparing population of NY City to Tampa by density per sq. mile.

Descriptive text from attribute tables that succinctly describes a feature. Examples include sampling points, city names, addresses.

Text or graphics that can be individually selected, positioned, and modified. Annotation can be in the form of inserted text or graphics, labels, or map features - used as 'bling'

The x-y graticule used to define locations of a 3-D surface depicted onto a 2-D map

Projections are based upon the congruency of the projection’s geometric shape to the geoid. Where the shape touches the geoid is a point or line of tangency. Map accuracy is greatest near a tangent point or line.

•Standard __________- Originate where the projected figure is tangent to the geoid being measured- lines extend East to West

•Standard _________- Originate where a figure is tangent to the geoid- lines extend North and South converging at the poles.

________________ datum give location and _____________ datum give altitude

A ______________ is a geometric figure resembling a flattened sphere; a ____________ is the actual shape of the Earth, which has many irregularities.

Units based upon horology (the study of time) where each major unit is subdivided by 60 parts and again by 60 parts. The distance that each unit covers varies depending on the location’s latitude since these are measures of angles not distances.

Attempts to project the 3-D shape of the earth onto a two-dimensional surface (from geoid to paper); always distorts some aspect of the true 3-D object depending on type of projection used.

A projected coordinate system is associated with a geographic coordinate system but the following adjustments may be made:

•False ______________- In a map projection a distance measure is added to eliminate negative measurements of parallels

•False ______________- A distance measure added to a geographic coordinate system to eliminate negative coordinate system values of meridians in a projection

A reference system that uses points, lines and surfaces to determine positions anywhere in 2- and 3- dimensional space

A task where a scanned map (raster) is aligned to a known coordinate system. Used to align photographic and other data to a known map.

________________ is the measure of the angle between the equator and the parallel on which a point lies. 0 to 90 degrees North or South (or 0 to -90), while ____________ is the angle between the prime meridian and the meridian on which a point lies. 0 to 180 degrees East or West

Any system that uses measures of Longitude and Latitude

A _________ is the fit of a theoretical sphere, spheroid, or geoid to a surface; these are used to apply measures of longitude and latitude to exact locations on Earth's surface. WGS 84 (G1674) NAD83 are examples.

The units of measure used in a geographic coordinate system (such as degrees-minutes-seconds or decimal degrees)

When the GIS system conforms a data frame from succeeding layers to the original data frame of the map, called the base map.

Each degree in a geographic coordinate system is divided into 10-100-1000-10,000 sections to specify exact position. Ex: 36.2312 degrees Distance of each division dependent on latitude.
