If your data is unprojected, that is, GCS, then use the GP tool "Calculate Field" to compute the geodesic distance (just as Network Analyst does). You can add a new length field and then use the python expression like !shape.geodesicLength@miles!

Can you post a picture of your route on one of these "reverse" turns? Perhaps their are divided highways and there may be two left or two right turns at the location. It is also likely that this is the only possible route and so it is taking the high penalty to get there. This can happen due to other restrictions or disconnected edges in the network.

You can use the Point Distance GP tool to compute straight line distances between one set of points to another. Details here: http://resources.arcgis.com/en/help/main/10.1/index.html#//00080000001r000000 You can also create a synthetic network and solve the TSP using your points. That is, use the Fishnet tool to create a appropriately dense grid of lines covering your points. Then create a network on that fishnet and solve the Route with Reorder Stops to Find Optimal Route. And you can control where the route starts and ends or simply do not care for either of these. Jay Sandhu ... View more

The Data and Maps DVD content is available online by first logging into the customer care portal at customers.esri.com You can download the streetmap network data from there. Or if you have the DVD handy you can copy it from there. Jay Sandhu ... View more

Service area is about which roads you can reach from a start facility up to the specified break value. The polygons are generated from the lines that were reached and NOT reached. Service Area polygon generation is like "contouring". Places that can be reached on the street network have a specific "height" value (that is, the travel time or distance away from the start facility). But what about the places that are not reached? So those places are added at a higher cost and resulting contour will have a non-convex shape and you will see the "extra" vertices as you put it. Jay Sandhu ... View more

It is not clear what you are asking. Can you be more specific? Jay Sandhu ... View more

You can make a network dataset based on a dense grid of lines (say 100 meter or less spacing) with the "Create Fishnet" GP tool. You can give the polygon paddock as the constraining feature class. Now that you have a "street" network, you can use the Route solver with the "Reorder stops to find Optimal Route" option and get the best way to visit these 20 locations. Jay Sandhu ... View more

There are a couple of ways to do this: 1. Use closest facility solver. Select all the students that go to the same school. Load these student locations as Incidents and that one school as the facility and now solve for 1 closest. This will give you the path/distance for that set. Repeat for the next school. 2. Use the route solver. You have to set up your data such that each student and their school is a pair of points you will load into the route solver with a common ROUTENAME id. In this way you can load all students and their school as start/end pairs and solving this will give you distances for each point pair. You can search the forums for ROUTENAME and see more on how to set that up. Jay Sandhu ... View more

Best thing is to do a couple of tutorials: http://resources.arcgis.com/en/help/main/10.2/#/About_the_ArcGIS_Network_Analyst_extension_tutorial/00470000005r000000/ The most likely reason the solvers are grayed out are these two: 1. You did not enable the extension. Use the Customize drop down and then pick Extensions and make sure Network Analyst is turned on. 2. You have not added a network dataset to the ArcMap table of contents. Without any street network data you can not perform any analysis. If you do not have any data, you can look at using the free streetmap data that comes on the Data and Maps dvd. Jay Sandhu ... View more

Here is a doc link to what Joe described in the previous reply. http://resources.arcgis.com/en/help/main/10.2/index.html#/using_Find/00470000003r000000/ Jay Sandhu ... View more

Create a 3D point feature class and set the Z value to the floor value they need to snap to. Network Analyst supports network datasets with true 3D. You can also look at the indoor routing tutorial that comes with the software.

At 10.1 a new problem type called "Maximize Capacitated Coverage" problem type to honor the capacity of each facility for this purpose. More details here: http://resources.arcgis.com/en/help/main/10.2/#/Location_allocation_analysis/004700000050000000/ Jay Sandhu ... View more

The solve will solve for all facilities not selected ones. If you have two that need to be resolved, and you wanted to default overlapping service areas then you can create (or copy) a new service area layer, load those two unsolved facilities into it and re-solve. Jay Sandhu ... View more

It is in the Route solver (not OD). More help here: http://resources.arcgis.com/en/help/main/10.2/#/Route_analysis/004700000045000000/ Jay Sandhu ... View more

If you search the streetmap folder, can you locate a streets.rs file? That is what you need to navigate to in ArcCatalog and it will show up as streets with a network icon that you can add to ArcMap. You should also see a streets.rsx folder that contains the network information. If you cannot find that file then you may not have the product properly installed. Also make sure that product is licensed on the computer you are trying to use it in. If you are not sure you can use the ArcGIS Adminstrator to see your data licenses. Jay Sandhu ... View more
