Calculate Locations
Adds fields to the input
features that contain the network location of the features. The tool is used to
store the network location information as feature attributes to quickly load
the features as inputs for a network analysis layer.
1. Input Features
The input features for
which the network locations will be calculated.
For line and polygon
features, since the network location information is stored in a blob field
(specified in the Location ranges field parameter), only geodatabase feature
classes are supported.
2. Input Analysis Network
The network dataset used
to calculate the locations.
If a sublayer of a
network analysis layer is used as input features,
the parameter is
automatically set to the network dataset referenced by the network analysis
layer.
3. Search Tolerance
The search tolerance for
locating the input features on the network. Features that are outside the
search tolerance are left unlocated. The parameter includes a value and units
for the tolerance.
4. Search Criteria
Specifies which sources
in the network dataset will be searched when finding locations and what
portions of geometry (also known as snap types) will be used.
For geodatabase network
datasets, the snap types can be specified for each subtype of the network
source (["Streets : Local Streets","SHAPE"]).
When calculating
locations for line or polygon features, only the SHAPE snap type is used, even
if other snap types are specified.
5. Find Closest among All Classes (optional)
- Checked—Matches the new network locations to the closest network source among all the sources that have a snap type specified in the search criteria. This is the default.
- Unchecked—Matches the new network locations to the first network source having a snap type specified in the search criteria. The sources are searched in the priority order, and the searching stops when the location is found within the search tolerance.
6. Exclude Restricted Portions of the Network (optional)
This parameter is applicable only when the input features are from the sub layer of a network analysis layer and are not barrier objects.
- Checked The network locations are only placed on traversable portions of the network. This prevents placing network locations on elements that you can't reach due to restrictions or barriers. Before relocating your network locations using this option, make sure that you have already added all the restriction barriers to the network analysis layer to get expected results.
- Unchecked The network locations are placed on all the elements of the network. The network locations that are relocated with this option may be unreachable during the solve process if they are placed on restricted elements.
7. Search Query (optional)
Specifies a query to
restrict the search to a subset of the features within a source feature class.
This is useful if you don't want to find features that may be unsuited for a
network location. For example, if you are loading centroids of polygons and don't
want to locate on local roads, you can define a query that searches for major
roads only.
An SQL expression for a
given source is specified by selecting the source name in the Name column and
clicking the SQL button. If you don't want to specify a query for a source,
remove the SQL expression for that source by selecting the source name and
clicking the Remove button.
By default, no query is
used.
8. Source ID Field (optional)
The name of the field to
be created or updated with the source ID of the computed network location. A
field named SourceID is created or updated by default.
9. Source OID Field (optional)
The name of the field to
be created or updated with the source OID of the computed network location. A
field named SourceOID is created or updated by default.
10. Percent Along Field (optional)
The name of the field to
be created or updated with the percent along with the computed network
location. A field named PosAlong is created or updated by default.
11. Side of Edge Field (optional)
The name of the field to
be created or updated with the side of edge on which the point feature is
located on the computed network location. A field named SideOfEdge is created
or updated by default.
12. Located X-Coordinate Field (optional)
The name of the field to
be created or updated with the x-coordinate of the computed network location.
A
field named SnapX is created or updated by default.
13. Located Y-Coordinate Field (optional)
The name of the field to
be created or updated with the y-coordinate of the computed network location. A
field named SnapY is created or updated by default.
14. Distance from Feature Field (optional)
The name of the field to
be created or updated with the distance of the point feature from the computed
network location. A field named Distance is created or updated by default.
15. Located Z-Coordinate Field (optional)
The name of the field to
be created or updated with the z-coordinate of the computed network location. A
field named SnapZ is created or updated by default.
16. Location Ranges Field (optional)
The name of the field to be created or updated with the location ranges of the computed network locations for the line or polygon features. A field named Locations is created or updated by default.
Copy Traversed Source Features
How to use Copy Traversed
Source Features Tool in Arc Toolbox ArcMap ArcGIS??
Copy Traversed Source Features
Path to access the tool
:
Copy
Traversed Source Features Tool, Analysis Toolset,
Network Analyst Tools Toolbox
Copy Traversed Source Features
Creates two feature
classes and a table, which together contain information about the edges,
junctions, and turns that are traversed while solving a network analysis layer.
1. Input Network Analysis Layer
The network analysis
layer from which traversed source features will be copied. If the network
analysis layer does not have a valid result, the layer will be solved to
produce one.
2. Output Location
The workspace where the
output table and two feature classes will be saved.
3. Edge Feature Class Name
The name of the feature
class that will contain information about the traversed edge source features.
If the solved network analysis layer doesn't traverse any edge features, an
empty feature class is created.
4. Junction Feature Class Name
The name of the feature
class that will contain information about the traversed junction source
features, including system junctions and relevant points from the input network
analysis layer.
If the solved network analysis layer doesn't traverse any
junctions, an empty feature class is created.
5. Turn Table Name
The name of the table
that will contain information about the traversed global turns and turn
features that scale cost for the underlying edges. If the solved network
analysis layer doesn't traverse any turns, an empty table is created. Since
restricted turns are never traversed, they are never included in the output.
Directions
How to use Directions Tool in Arc Toolbox ArcMap ArcGIS??
Directions Tool
Path to access the tool
:
Directions Tool, Analysis Toolset, Network Analyst Tools Toolbox
Directions
Generates turn-by-turn
directions from a network analysis layer with routes. The directions can be
written to a file in text, XML, or HTML format. If you provide an appropriate
stylesheet, the directions can be written to any other file format.
1. Input Network Analysis Layer
Network analysis layer
for which directions will be generated. Directions can be generated only for
route, closest facility, and vehicle routing problem network analysis layers.
2. Output File Type
The format of the output directions file. This parameter is ignored if the stylesheet parameter has a value.
- XML—The output directions file will be generated as an XML file. Apart from direction strings and the length and time information for the routes, the file will also contain information about the maneuver type and the turn angle for each direction.
- TEXT—The output directions file will be generated as a simple TXT file containing the direction strings, the length and, optionally, the time information for the routes.
- HTML—The output directions file will be generated as an HTML file containing the direction strings, the length and, optionally, the time information for the routes.
3. Output Directions File
The full path to the
directions file that will be written.
If you provide a
stylesheet in the Stylesheet parameter, make sure the file suffix for Output
Directions File matches the file type your stylesheet produces.
4. Report Length in These Units
Specifies the linear
units in which the length information will be reported in the directions file.
For example, even though your impedance was in meters, you can show directions
in miles.
5. Report Travel Time (optional)
- Checked—Report travel times in the directions file. This is the default value.
- Unchecked—Do not report travel times in the directions file.
6. Time Attribute (optional)
The time-based cost
attribute to provide travel times in the directions. The cost attribute must
exist on the network dataset used by the input network analysis layer.
7. Language (optional)
Choose a language in
which to generate driving directions. The languages that are shown in the
drop-down list depend on which ArcGIS language packs are installed on your
computer.
Note that if you are
going to publish this tool as part of a service on a separate server, the
ArcGIS language pack that corresponds with the language you choose must be
installed on that server for the tool to function properly. Also, if a language
pack isn't installed on your computer, the language won't appear in the
drop-down list; however, you can type a language code instead of choosing one.
8. Style Name (optional)
Choose the name of the formatting style for the directions.
- NA Desktop—Printable turn-by-turn directions
- NA Navigation—Turn-by-turn directions designed for an in-vehicle navigation device
- NA Campus—Turn-by-turn walking directions, which are designed for pedestrian routes
9. Stylesheet (optional)
·
The stylesheet for generating a formatted output file type (such
as a PDF, Word, or HTML file). The suffix of the file in the output directions
file parameter should match the file type that the stylesheet generates. The
Directions tool overrides the output file type parameter if this parameter
contains a value.
· If you want a head start on creating your own text and HTML stylesheets, copy and edit the stylesheets Network Analyst uses. You can find them in the following directory: <ArcGIS installation directory>\ArcGIS\Desktop10.2.1\NetworkAnalyst\Directions\Styles. The stylesheet is Dir2PHTML.xsl, and the text stylesheet is Dir2PlainText.xsl.
