Tile objects: The shape is defined by a single tesseral address.
Zone objects: The shape is comprised of more than one address.

Tile is a subset of a GIS database that contains information about one subarea of the overall digital map. Tiles are an effective way of dividing a continuous map into units which can be easily created, edited, and analyzed.
Tile A part of the database in a GIS representing a discrete part of the earths surface. By splitting a study area into tiles, considerable savings in access times and improvements in system performance can be achieved.
Cross-tile Topology
The encoding of topological relationships in such a manner that those relations are maintained even when a data layer has been physically partitioned into multiple tiles. (Compare with Seamless Database)

Tile - the spatial unit by which geographic data is organized, subdivided, and stored in a map library. Tiles subdivide the area covered by a map library and organize the library data by location (e.g.
Tile the Racial Poverty Layout and Racial Composition View in ArcView. Click the box next to the White Poverty theme to turn it on. Notice the "View Frame" and "Legend Frame" went grey.
Tile - A digital storage unit that is the equivalent of a paper map, i.e. digital map files are stored by tiles.

A tile with a hole, filled with one or more other tiles, is not permissible, because the network of all sides inside and outside is disconnected. However it is allowed with a cut so that the tile with the hole touches itself.
Each tile is available at a resolution of 1800 Ã- 1800 pixels (approximate file size 1 MB, 60 pixels = 1 degree, 1 pixel = 1 minute)

cross-tile indexing
A technique for indexing features that cross tile boundaries in a map library by storing them as one or more features in each tile, instead of storing them each as a single feature.

Each SRTM data tile contains a mosaic of elevations generated by averaging all data takes that fall within that tile.
-1 Input is a 1-arcsec tile (default: 3-arcsec) --overwrite Force overwrite of output files
Parameters:
input=string SRTM input tile (file without .hgt.zip extension) output=string Output raster map (default: input tile) ...
For example, we wish to determine which SRTM-30 tile contains the SRTM-3 tile. First, determine the coordinates of your SRTM-3 tile. They are 38 degrees north latitude and 84 degrees west longitude for my example.
Tile the two windows side by side. Because R2V uses an image coordinate system where the upper left corner is the origin (0,0), you may see some geo-coded vector files displayed upside down (for example, some SHP files).
For example, an OS LandForm Panorama tile, 20km square and with a 50m cell separation, holds 401 rows and columns - 160,801 cells. The same area in the LandForm Profile data set, with a cell separation of 10m, comprises 402,002,500 cells.
Using Spatial Analyst this tile was clipped, warped with an order-three polynomial to approximate an Equidistant Conic projection (Clarke 1866 spheroid, central meridian 71 degrees west, reference latitude 19 degrees north, ...
And photos taken from the air always have so much distorion that it is impossible to tile together a mosaic of photos of a site that has the sort of scale as we would expect from a plan.
If the polyhedral faces cover (i.e. tile or tessellate) the plane when juxtaposed, the map can be useful even in its unfolded form. Any triangle or quadrilateral tiles the plane, like a regular hexagon does, but the regular pentagon does not.
Or the analysis might discover an area of abnormally low yield as linked with a section of old drainage tile in need of repair.
This is the key to Google's fast speed when loading maps, they have all been previously created and Google simply loads them to your browser when needed. These images are called tile caches because they are a series of images that are placed next to ...
As regards the searching itself the network implementation needs only to find the particular tile(s) while the DEM or TIN representations require to search and retrieve also the values inside the tile(s).
streak The color of a mineral in its powdered form, usually obtained by rubbing the mineral against an unglazed porcelain tile to see the mark it makes. A mineral harder than the tile must be pulverized by crushing.
Go to the GLOBE project home page, and follow the links to either select your own area or download a preset tile. Note that you'll need to download the .clr and .hdr files too- get them here.
Rooms can be drawn on screen using the graphical features of the package, if required. Luminaries are positioned graphically and luminaire grids can be generated automatically onto tile layouts. Internal obstructions can be included.
Special data structure used in a database to speed searching for records in tables or spatial features in geographic data sets.
ArcInfo supports both spatial and attribute indexes. See also item indexing, cross-tile indexing and spatial indexing.
