Tracing
Find out the path your signal is taking to reach its destination. Geo Web Publisher for Communications will locate graphically any optical system path or fiber route on the map via the trace capabilities.
Raster Tracing
Raster tracing is useful in cases in which you need to have more control over the vectorization process or need to vectorize a small portion of an image.
[edit] Tracing capability
In case single objects are lost, the capability to trace the whereabouts is another option to get access to the missing target again.
Network Tracing: In utility networks, this refers to highlighting all node and link features within a gravity of pressure network that are both physically and logically connected to a test point within the network according to a specified set of ...
Tracing it further back, some identify its roots in the breakdown of Hegelian idealism, and the impact of both World Wars (perhaps even the concept of a World War).
Tracing the effect of site-specific farm management requires a look at where the industry has been, where it is and where it's headed.

The line tracing process extracts two types of lines: center line and boundary line. The center line method tracks the center pixel within a raster line and follow to the line until it reaches an intersection or the end of the line.
A true vector tracing of the area edges might appear blocky, since the vectors outline the edges of raster data that are stored in rectangular cells. To produce a better-looking vector map, r.to.
For your information, I have found that setting the tool options for the terrain model tool to Tirangulated Contour Model with Triangulate Non-Sloping produces the most faithful models. Setting your RenderZone Options to Raytracing ...
A contour is a line tracing out locations of constant elevation. There may be more than one contour for any elevation; the contour tool computes only the contour passing through the point of application.
In the above diagram, note first the intensity peak in the tracing associated with the steep slope of the mountain side facing the passing aircraft.
They found that “One third of the Americans we interviewed were involved in tracing their family’s history—which suggests that more historical research is done on families in this country than on any other subject.' ...
These include very sophisticated, semi-automatic, tracing tools which, for an ideal image, can often vectorise perhaps 70-80% of the data without intervention and which automatically request intervention when a problem cannot be resolved.
The digitizing tool is designed for tracing contour lines. This is the traditional way to extract contour lines from topographical maps. In this method, the operator laboriously traces over contour lines on a paper map using a digitizing tablet.
The point and line data were selected by manually tracing the data onto an overlying clear plastic film. The selected data were then digitised.
upstream In tracing, upstream is the direction along the arcs that is against the direction of flow. Direction of flow is determined by a user-defined convention. See directed network. User-ID Synonymous term for Cover-ID and feature-ID.
Weather maps are created by plotting or tracing the values of relevant quantities such as pressure, temperature, cloud cover, and others, onto a geographical map. The data can be either measurements or forecast values.
Heads-up digitizing involves the tracing of geographic data directly on top of the aerial imagery instead of through the traditional method of tracing the geographic form on a separate digitizing tablet. CADD and CAD redirect here. ...
In forming an image, it often helps to imagine moving around it, or tracing it out with your hands. The size of an image is important.
[data capture] Manual digitization by tracing a mouse over features displayed on a computer monitor, used as a method of vectorizing raster data.
Maps can be digitized by hand-tracing with a computer mouse on the screen or on a digitizing tablet to collect the coordinates of features. Electronic scanners can also convert maps to digits (fig. 7).
Screen digitizing - The process of acquiring vector graphics by tracing the raster image displayed on the computer screen. This can be done manually or with the aid of computer software. Also commonly referred to as heads-up digitizing.
Much like tracing a family tree, data can be traced through parents along paths through the hierarchy. Users must keep track of the hierarchical structure in order to make use of the data.
board digitizing
The hand guided electronic tracing of hard copy maps on a digitizing board.
Digitizing involves tracing features on a source map, taped to the digitizing tablet, with a precise cross hair in the digitizing cursor and instructing the computer to accept the location and type of feature.
2. Tablet digitizing is a common method of getting data into a GIS. The procedure involves tracing lines or locating points with a computer mouse on a digitizer.
On-screen digitizing is the creation of a spatial dataset by tracing over features displayed on a computer monitor with a mouse. In both cases, the newly created dataset picks up the spatial reference of the source document.
is placed on a digitizing table (Fig. 8) and a pointing device (called a cursor, puck, or mouse) is used to record coordinates of features to be extracted from the map. The digitizing table electronically encodes the position of the cursor. Tracing ...
Table of Direct, Indirect and Induced Coefficients: "induced" effects are the result of extending the tracing of indirect effects "through" households, i.e.

It can be outlined on a topographic map by tracing the points of highest elevation (usually ridge crests) between two adjacent stream valleys. The watershed of a large river usually contains the watersheds of many smaller streams.
In geographic applications, digitizing usually means tracing map features into a computer using a digitizing tablet, graphics tablet, mouse, or keyboard cursor. DIPR See Draft Interoperability Program Report.
