Grid Systems
A grid system allows the location of a point on a map (or on the surface of the earth) to be described in a way that is meaningful and universally understood.

Cell
A discretely uniform unit that represents a portion of the Earth. such as a square meter or square mile.

Grid-based map analysis is increasingly used to characterize conditions and impacts of infrastructure networks, such as pipe and power lines.

Generation and GIS
generation is a broad field with applications in aerodynamics, material science, biology, earth science, chemistry and physics, for example.

Grid templates available with the installation
A number of grid templates are delivered with ArcGIS and are located under the ArcGIS installation directory (\ArcGIS\Desktop10.1\GridTemplates).

The grid drawing may be turned off by using the -n flag.
The border drawing may be turned off by using the -b flag.
The coordinate text may be turned off by using the -t flag.

Using a UTM overlay tool
If you want to find your location with more precision than is available from the lines on the map, you will need a tool that is marked in finer divisions. One such tool is a overlay.

Grid layers
Overview
Grid layers are graphical representations of the ArcGIS and ArcInfo implementation of the raster data model. Grid layers are stored with a numeric value for each cell.

Grid Snaps: It is difficult to put your mouse exactly on (90,90,0) isn't it? Right now, our drawing has a resolution down to the inch. Our life would be simpler if we could make out mouse snap to even increments of 10 feet.

-- (1) a set of cells forming a regular, or nearly regular, tessellation of a surface; (2) a set of points arrayed in a pattern that forms a regular, or nearly regular, tessellation of a surface.

Grid
A pattern of regularly spaced horizontal and vertical lines forming square zones on a map used as a reference for establishing points. Grid examples are UTM, MGRS, and Maidenhead.

: A geographic data model representing information as an array of equally sized square cells arranged in rows and columns. Each cell is referenced by its geographic x,y location.

GRIDA fully integrated grid(cell-based) geoprocessing system for use with ARC/INFO. GRID supports a Map Algebra spatial language that allows sophisticated spatial modeling and analysis.

U.K.: Yeoman PLC's Navigator Pro is a plotting table with GPS inputs that works with Admiralty charts. Quite impressive.

The grid represents lines having constant rectangular coordinates (x, y). The grid is almost always a rectangular system and is used on large and medium scale maps to enable detailed calculations and positioning.

ESRI
The Arc/Info Binary format is the internal working format of the ESRI Arc/Info product. It is also usable and creatable within the spatial analyst component of ArcView 3.x.

4 Grid references
Store grid references in an appropriate notation for easy transition to a GIS or conversion to an appropriate map projection (e.g.

The UTM
The best known use of the transverse Mercator projection is the specialized form called Universal Transverse Mercator (UTM) projection system.

Image and Attribute Distinction
The graphic side of a map is the lines and descriptors. Examples of these lines are rivers or roads.

Grid data sets come from many sources: remote sensing devices, converted topographic maps, interpolated point data, conversion from vector features, and derived from other features (through distance, proximity, and density calculations, for instance).
