How often, or on what system, the Thought Police plugged in on any individual wire was guesswork. It was even conceivable that they watched everybody all of the time. But at any rate they could plug in your wire whenever they wanted to.
This is the default installation location for the tutorial data. The Network Dataset Properties dialog box opens. Click the Attributes tab. A restriction attribute represents a driving preference or requirement; for instance, Avoid Unpaved Roads lets you avoid any gravel, dirt, or other unpaved roads.
Height Restriction makes it possible to route around any clearances that are lower than the height of your vehicle. If you are carrying corrosive materials on your vehicle, using the HazMat: Corrosive Goods Restricted restriction prevents hauling the materials along roads where it is marked as illegal to do so.
A parameter named Restriction Usage is automatically added when you create a restriction attribute. In the following steps, you will take a closer look at this parameter. The Add New Attribute dialog box opens. Choose Restriction from the Usage Type drop-down list.
The Restriction Usage property is enabled. Click the Restriction Usage drop-down list to see the options available. This property sets the default value for the Restriction Usage parameter and thus sets the default behavior for the restriction attribute you are creating.
The value specifies whether the elements that use the restriction are prohibited, preferred, or avoided; also, it specifies the degree to which they are avoided or preferred.
Later in this exercise, you will use a restriction attribute to avoid toll roads. This means that when the restriction is used, the solver will try to route around toll roads when it can. Medium also indicates how important it is to avoid toll roads in a network analysis; it has a medium priority.
Low would put lower importance on avoiding tolls; choosing Avoid: High instead would give it a higher importance and thus make it more acceptable for the solver to generate longer routes to avoid tolls. Choosing Prohibited would entirely disallow travel on toll roads, making it impossible for a route to traverse any portion of a toll road.
Keep in mind that avoiding or prohibiting toll roads, and thus avoiding toll payments, is the objective for some; in contrast, others prefer to drive on toll roads because avoiding traffic is more valuable to them than the money spent on tolls.
In the latter case, you would choose Prefer: The higher the preference, the farther the solver will go out of its way to travel on the elements that use the restriction.
Due to these kinds of differing perceptions and needs, the ArcGIS Network Analyst extension adds the Restriction Usage parameter to restriction attributes by default. The Add New Attribute dialog box closes. You can change the default value of a Restriction Usage parameter at any time.
The next steps show how you can do this. Click Avoid Toll Roads.
The Avoid Toll Roads Parameters dialog box opens. Notice that the default value is Avoid: By clicking this value and choosing a different value, the default value would be changed; however, leave this value as it is.
The Avoid Toll Roads Parameters dialog box closes. The Network Dataset Properties dialog box closes. Examining the Restriction Usage parameter in the network analysis layer properties In this section, you will take a quick tour of where you can view and change the restriction attribute settings of a network analysis layer.NIM - Provide option to authorize x products without exposing authorization numbers by using encrypted provisioning file.
NIM - High Latency/Low Bandwidth connections including VPNs may prevent license borrowing. An organizational account with the premium content geocoding privilege is required to access ArcGIS World Geocoding Service, and any views of it, (including publishing CSV or Excel files as hosted feature layers) To limit search results to matches that are at least this precise.
This was an ambitious scheme in , attempting to smooth the distribution of a multitude of proprietary formats and display methods. The concept was simply to make access to spatial data a “write once, use anywhere architecture.”.
So basically if I generate a license file geodatabase will not resolve my query which I have posted in another thread, i.e. my intent of applying copying restrictions to a kmz/kml that I created in ArcMap.

Queries are used to select a subset of features and table records. All queries in ArcGIS use standard Structured Query Language (SQL). Here you will learn how SQL syntax works and the two ways you can write queries using the query builder.
