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.

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: ...

Directly read, merge, and view available DTED files within a user-defined extent. Find the highest point, then hillshade the merged data with ease. View, select, and merge DTED cells with ease.

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.

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.

merge. To take two or more maps or data sets and combine them together into a single, coherent map or database without redundant information. metadata. See data dictionary. model.

Raster Editing - edit raster features, new features can be created and merged back into the raster, raster can be merged together, or vector data merged into a raster. Text Recognition - powerful text recognition that really works.

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.

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).

During the process of overlay, the attribute data associated with each feature type id merged. The resulting table will contain both the attribute data. The process of overlay will depend upon the modelling approach the user needs.

In general, up to 80% of the information on a digital map consists of lines, giving rise to the extensive list of generalisation operators that exist - including simplify, smooth, displace, merge, enhance and omit.

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 ...

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. Top of page Important notices ...

Merge all available surrounding quads (up to 8 plus the quad itself) /* and re-clip the grid using the generated polygon coverage Convert the DRG from GRID to TIFF image Clean-up Create the Image Catalog ...

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.

Abstract: TAXDistricts is the County Taxing districts maintained by the Property Appraiser's GIS Division. The layer is updated from annexed parcels that are merged to the existing district boundaries to recreate the new district boundaries.

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.

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).

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 ...

This translates into confusion, especially in GIS where these two fields are merged. To circumvent this problem we use the terms fine scale for small area projects with higher detail and broad scale for large area projects with less detail.
