Merge Multiple Maps: Use R2V to vectorize maps separately and then merge them into one set by specifying proper control points. The merged vector data set can then be edited within R2V and treated as a single map.
Merge:
Combine items from two or more similarly ordered sets into one set that is arranged in the same order.
Splice separate but adjacent mapped areas into a single data set.
New Merge Nodes in Close Proximity tool to automatically merge duplicate nodes and reconnect conduits.
It is now possible to import/export SewerGEMS' sub-models.
Interpretation of results ...
A spatial merge creates a new layer in which multiple input features one common attribute value are merged into single features. The new features need not be adjacent.

extract drained soil polygons (drainage = 2, therefore soil = A) ...
The merge, dissolve editing functions play important role by the feature selection based on the generalized attributes. Some other editing functions as rotate, pan, cut, copy, paste, erase, snap, etc. are useful for developing designed objects.
Oppose merge of GIS in Archaelogy into this article. The GIS article is alread far too long. I suggest Wikifing the Archaelogy article. I am about to pull section of the GIS article out into it's own article. --Ray 10:52, 22 March 2006 (UTC) ...
The spatial merge of a theme of adjacent or overlapping polygons produces features that look simple but internally are very complex.
To update or merge NAD27 and NAD83 geocoded image and map data would require the rectification of old images to new NTS map sheet standards which are in NAD83.
Several more merge scenes round out the picture. The next fuses a Landsat TM color composite at 30 m resolution with and IRS (Indian remote sensing program) 5 m panchromatic image of an unnamed town, with impressive results: ...

Suppose we have merged the two closest elements b and c, we now have the following clusters {a}, {b, c}, {d}, {e} and {f}, and want to merge them further.
When you are done, merge the layers, crop the border, and save as a .bmp file. Now you are ready to overlay the image using 3DEM. This is done in the usual fashion. Download and open the SDTS 1:24,000 Salem, NY DEM into 3DEM.
Brovey transform to merge multispectral and high-res panchromatic channels

Generates statistics for i.maxlik from raster map layer.
108 a procedure that calculates the geometric relationships between two geographic representations (usually applied to vector models); used to merge attribute information . primitives p.
Created when two glacier and their lateral moraines merge. Median Statistical measure of central tendency in a set of data. The median is the value halfway through a data set where the values have been ordered from lowest to highest.
to potential users; evaluation of new institutional arrangements that can provide quality assurance mechanisms in emerging digital worlds; and development of methods for data registration, fusion, and conflation that allow information to be merged ...
Most topics tend to merge into other topics at the edges. Therefore, it is important to set clear boundaries, so that when you consider a particular subtopic or an organization with records, ...
Vertical integration Corporate mergers involving firms which are involved in forwardly or backwardly related production stages, i.e. they buy each other's inputs or outputs.
For example, reasoning that a land cover type classified as Deciduous Needleleaf Trees in one dataset is a specialization of land cover type Forest in another more roughly-classified dataset can help a GIS automatically merge the two datasets under ...
The very bottom layer of our merge function provides information on the cost of crossing non-road cells. This layer is basically a layer representing land with the value of "0.01" and all of the water areas are 'nodata.
DTED is an analysis and merge tool. Using the DTED tool, the applicable Digital Terrain Elevation Data (DTED) tiles can be automatically selected and merged into a single grid. A hillshade may be applied for ease of interpretation and display.
Here the spatial representation of an object and its related non-spatial attribute are merged into a unified data file.
Then I merge this with a second point file that has the individual benchmark points indicated on the original map (such as the tops of peaks).
This data, when merged with GPS precision navigation will create the type of digital images needed to provide clear out-the-window vision needed to greatly reduce flight into terrain type accidents -- the number one cause of aircraft fatalities ...
polygon overlay : A process that merges spatially coincident polygons from two coverages, and their attributes, to create a third coverage, that contains new polygons and describes new relationships ...
of important cities were granted the status of counies in their own right, such as London, Bristol, Coventry, and numerous small exclaves such as Islandshire were created. The next major change occurred in 1844 many of these exclaves were re-merged ...
Current and developing technologies for media mapping are changing that mode of thinking for many GIS users. Media mapping merges photography and geography to help users understand space by experiencing abstraction and reality through the integration ...
By using CSRS products and services we can be sure that the data we gather can be shared, exchanged or merged, confident that the positional information will be both consistent and compatible across digital boundaries.

While multi-part shapes are acceptable, each FMU may only have one record in the attribute table. To accomplish this, you can merge polygons and in ArcMap, or use ArcToolbox or the ArcView 3.x geoprocessing wizard to dissolve on the FMU_Name field.
Relate - A process in relational databases that logically merges two or more databases through the use of keys.
Relation - A table in a relational database in formally called a relation.
Other geographic operators commonly available in GIS packages are intersection, point in polygon, area in area, and other expressions of interrelationships between geographic entities that can be used to select, reject, merge, ...
Land often not residing within a square, most of which were created in 1905 by Act of Congress. All the unsubdivided land from Washington County merged with the city of Washington to form the District of Columbia.
Pictometry ...
If a polygon map of vegetation has a polygon that is too small to show, is it eliminated or is there a point at which it is merged with other polygons? In either case, the accuracy of the map is lowered.
Our GIS services allow for the visualization of geographic data, analysis of spatial relationships, and efficient data management. GIS data conversions allow data from different sources to be merged in one common format, which allows for easy access, ...
The ability to change map scales and to overlay maps can be deceiving; the user must be aware of the imprecision inherent in all cartography and of the ways errors compound when map scales are changed or when maps are merged (Abler 1987).
polygon-on-polygon overlay, line-on-polygon overlay, point-on-polygon overlay (figure 7.5). During the process of overlay, the attribute data associated with each feature type is merged. The resulting table will contain both the attribute data.
down from the upper surface, you would intersect the earth's surface at two elevations at the same X,Y coordinate. In this relatively rare case, the contour line representing the lower elevation is dashed. The only time two contour lines may merge is ...
