Absolute Location	An absolute location describes the location of a place based on a fixed point on earth.
Address	A designation of the location of a person's residence or workplace, an organization, or a building consisting of numerical and text elements, such as a street number, street name, and city, arranged in a particular format
Aestheic	Term used to talk about beauty or art and people's appreciation of beautiful things.
Attribute	Nonspatial information about a geographic feature in a geographic information system (GIS), usually stored in a table and linked to the feature by a unique identifier.
Autonomous	Functioning independently without control by others.
Base Line Data	Known values. This form of data acts as a basis of comparison for all experimental data in comparing knowns to unknowns
Brownfield	A brownfield is a property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant.
Canon	A general law, rule, principle, or criterion by which something is judged.
Commercial	Involving or relating to the buying and selling of goods.
Condensation	The process of water changing from a vapor to a liquid. Water vapor in the air rises mostly by convection. This means that warm, humid air will rise while cooler air will flow downward. As the warmer air rises, the water vapor will lose energy, causing its temperature to drop. The water vapor then has a change of state into liquid or ice.
Conversion Factor	Ratio used to convert one unit to the equivalent amount in a different unit of measurement.
Criteria	A means of judging. A standard, rule, or test by which something can be judged.
Cross Contamination	The process by which substances are unintentionally transferred from one area or object to another, with negative consequences.
Equitable	Equal and just treatment of all concerned.
Ethical Dilemma	A situation in which there is a choice to be made between two (or more) options, neither of which resolves the situation in an ethically acceptable fashion.
Evaporation	When radiant energy from the sun heats water and causes the water molecules to become so active that some of them rise into the atmosphere as vapor.
Evapotranspiration	The process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces, and by transpiration from plants.
Feature layer	A layer that references a set of feature data. Feature data represents geographic entities as points, lines, and polygons.
Field	A column in a table that stores the values for a single attribute.
Filter	A desktop geographic information system (GIS) operation used to hide (but not delete) features in a map document or attribute table.
Geocoding	A geographic information system (GIS) operation for converting street addresses into spatial data that can be displayed as features on a map, usually by referencing address information from a street segment data layer.
Geographical Features	Natural and artificial identifying features of the Earth.
Geospatial	Relating to information that identifies where particular features are on the Earth's surface, such as oceans and mountains.
Green Infrastructure	The planning and management of systems of landscapes and protected natural resources to counteract the negative impacts of development and create healthier and more sustainable urban communities.
High- Density Development	Residential and commercial development at a density higher than typically found in the existing community. The outcome of this type of development is often more homes, or residences, on a property.
Impervious	Not allowing entrance or passage.
Infiltration	The process of water seeping through the ground.
Infrasfructure	The basic physical and organizational structures and facilities (e.g., buildings, roads, and power supplies) needed for the operation of a society or enterprise.
Itinerary	A planned route or journey.
layer	The visual representation of a geographic dataset in any digital map environment.
low-density development	A residential zone intended for housing that includes a lot of open space, a small number of residential homes, and no large industries, apartment complexes, or other large structures.
Mass density	The measure of mass density is a measure of mass per volume.
Mathematical model	A representation of a real-world situation or system using mathematical concepts and language.
Median	A measure of center in a set of numerical data. The median of a list of values is the value appearing at the center of a sorted version of the list, or the mean of the two central values if the list contains an even number of values.
Network Logic	The collection of schedule activity dependencies that makes up a project schedule network diagram.
Query	A request for information.
Regression	A set of statistical processes for estimating the relationships among variables.
Relative Location	A relative location refers to the position of a place or entity based on its location with respect to other locations.
Residential	An area, designed for people to live in, containing houses rather than offices or factories.
Risk	An uncertain event or condition that, if it occurs, has a positive or negative effect on one or more project objectives.
Runoff	Precipitation that reaches the surface of the earth but does not infiltrate the soil.
Trade-Off	An exchange of one thing in return for another: especially relinquishment of one benefit or advantage for another regarded as more desirable.
Urban Sprawl	The spread of a city into the area surrounding it, often without planning.
Urbanization	The process by which a population moves from living in rural communities to cities.
Utility	Something useful to the public, especially the service of electricity, power, gas, water, telephone, etc.
Vaccine	A substance used to stimulate the production of antibodies and provide immunity against one or several diseases.
watershed	An area of land that contains a common set of streams and rivers that all drain into a single larger body of water, such as a river, lake, or ocean.
Orthographic Projection	A method of representing three-dimensional objects on a plane having only length and breadth. Also referred to as right angle projection.
Precipitation	The act of water being released from clouds as rain, snow, sleet, or hail.
Point	A geometric element defined by a pair of x,y coordinates.
Point Feature	A map feature that has neither length nor area at a given scale, such as a city on a world map or a building on a city map.
Policy	A set of ideas or plans that is used as a basis for making decisions, especially in politics, economics, or business.
Polygon	On a map, a closed shape defined by a connected sequence of x,y coordinate pairs, where the first and last coordinate pair are the same and all other pairs are unique.
Polyline	In ArcGIS software, a shape defined by one or more paths, in which a path is a series of connected segments. If a polyline has more than one path (a multipart polyline), the paths may either branch or be discontinuous.
Population	All the values in a data set that are collected during an observation or experiment.
Population Density	Population density is the number of people living in each unit of area (such as a square mile).
Pervious	A form of pictorial sketch in which vanishing points are used to provide the depth and distortion that is seen with the human eye.
Project Risk Management	The processes of conducting risk management planning, identification, analysis, response planning, and controlling risk on a project.
Quartiles	Division of a rank-ordered data set into four equal parts. The values that divide each part are called the first, second, and third quartiles; and they are denoted by Q1, Q2, and Q3, respectively.
