Terms
MapXtreme v7.1 625 Developer Guide
Hypertext Transfer Protocol (HTTP)
The message-based network interface between a Web client and a Web server. HTTP runs on top of
TCP/IP.
Inflection
The point in a grid map at which the color changes due to a change in the grid value or percentage.
See
Chapter 17: Grid Images and Inflections .
Internet Information Services (IIS)
The software services provided by Microsoft that support the creation, configuration, and
management of web sites. Specifically some commen Internet Information Services include: FTP
(File Transfer Protocol) and SMTP (Simple Mail Transfer Protocol). In MapXtreme, the WMS Server
we provide must be configured to work with IIS to run the Server.
ISession Interface
The MapXtreme MapInfo.Engine namespace interface that provides the starting point for all
MapXtreme applications. ISession manages the initialization of resources needed for a MapXtreme
application, and defines all data and functionality applicable to an instance of an application.
Latitude
The horizontal lines on a map that increase from 0 degrees at the Equator to 90 degrees at both the
North (+90.0 degrees) and South (-90.0 degrees) poles. Used to describe the north-south position of
a point as measured usually in degrees or decimal degrees above or below the equator.
Layer
A basic component of map display in MapInfo products, typically consisting of several superimposed
layers (e.g., a layer of street data superimposed over a layer of county or postal code boundaries).
When a table appears in a Map window, it occupies a layer in that Map window. Typically, each map
layer corresponds to one open table.
Linear Referencing
An alternative reference system to the traditional coordinate reference systems that tie locations of
linear features to points on the earth. Any physical asset that you can map as part of a linear network
can hold data that describes the asset or a condition or event related to that asset. In MapXtreme
the data is stored as an M, or measure value, on the MultiCurve object along with the X and Y
coordinates for the location. The M values can then be further mapped and analyzed for better
resource management. See
Chapter 21: Linear Referencing .
Longitude
The vertical lines on a map, running from the North to South poles, used to describe the east-west
position of a point. The position is reported as the number of degrees east (to -180.0 degrees) or
west (to +180.0 degrees) of the prime meridian (0 degrees). Lines of longitude are farthest apart at
the Equator and intersect at both poles, and therefore, are not parallel.
Longitude/Latitude
The default coordinate system for representing geographic objects in a map in MapInfo products.
MapControl
A MapXtreme object that enables you to view a map on a form. The MapControl owns the window
that the map draws to. It also controls the size of the map and interacts with the map tools.
MapXtreme provides desktop and web versions of MapControl.
