All Implemented Interfaces:

GPTool

public class VPFTile
extends AbstractGPTool

This tool only works with an ArcInfo license and will only be available in ArcToolbox if you have installed ArcInfo Workstation. Creates cross-tile topology for all tiled coverages in a Vector Product Format (VPF) database library, or topology for an individual tile in a VPF library. The tool is used for postprocessing of a coverage to The VPF Tile Topology tool is contained in the Coverage Tools tool box.

Software restrictions: ArcInfo only

Usage tips:

• Military Standard MIL-STD-2407 (June 28, 1996) refines the definition of cross-tile topology. The VPF Tile Topology command has been updated to meet the new specification. You may use the optional parameter to choose the 93 or 96 VPF Standard.
• VPF Tile Topology works on all tiled coverages of a VPF library or a single coverage within that library. The last optional parameter, VPF_cover, allows you to select a particular coverage in which cross-tile topology should be populated. It is more efficient, however, to implement VPF Tile Topology after all coverages for a library have been converted from ARC/INFO to VPF format.
• VPF Tile Topology using the 1993 VPF Standard does not handle the situation where more than two edges coincide along a tile boundary. It is impossible for VPF Tile Topology to know how to assign left-face and right-face values to each edge.
• The 1996 VPF Standard requires that cross-tile topology be implemented on the connected nodes. For cross-tile to work correctly, the "first_edge" column in the connected node tables must be a Triplet type.
• Since VPF Tile Topology makes modifications to the primitive file in your VPF database, it is important to understand the requirements of the VPF data before the cross-tile process can occur correctly. The most important things to remember about creating 1996 cross-tile topology are the following:
• The following environments affect this tool: derivedPrecision; newPrecision; projectCompare; scratchWorkspace; , and workspace;

Constructor Detail

VPFTile

public VPFTile()

Creates the VPF Tile Topology tool with defaults.

Initializes the array of tool parameters with the default values specified when the tool was created.

VPFTile

public VPFTile(Object vPFLibrary)

Creates the VPF Tile Topology tool with the required parameters.

Initializes the array of tool parameters with the values as specified for the required parameters and with the default values for the other parameters.

Parameters:

vPFLibrary - Folder | VPF Library, location of the VPF database library for which cross-tile topology is to be created.

Method Detail

getVPFLibrary

public Object getVPFLibrary()

Returns the VPF Library parameter of this tool . This parameter is Folder | VPF Library, location of the VPF database library for which cross-tile topology is to be created. This is a required parameter.

Returns:

the VPF Library

setVPFLibrary

public void setVPFLibrary(Object vPFLibrary)

Sets the VPF Library parameter of this tool . This parameter is Folder | VPF Library, location of the VPF database library for which cross-tile topology is to be created. This is a required parameter.

Parameters:

setSigDigits

public void setSigDigits(int sigDigits)

Sets the Significant Digits parameter of this tool . This parameter is Long, the number of digits the software will use when trying to match node coordinates at tile boundaries. The larger the number, the smaller the search tolerance. The default value is 4. This is an optional parameter.

Parameters:

sigDigits - Long, the number of digits the software will use when trying to match node coordinates at tile boundaries. The larger the number, the smaller the search tolerance. The default value is 4.

getVPFStandard

public int getVPFStandard()

Returns the VPF Standard parameter of this tool . This parameter is Long, the VPF Standard to be used. The VPF Standard has two options to define cross-tile topology. This is an optional parameter.

Returns:
