Some other web software (not esri) would like to use the results of a visibility analysis (Viewshad). They are sending the observation points with all other information (radius, offset etc.) The problem is how to return the results. They would not like the results it to be saved on disk (for performance reason) but the image to be returned as an object in memory with some information on where it is in the world. The client application should be responsible to draw it in the correct location. How can this be done? Thanks

Should it be so complex? Let me separate the problem into two different problems. 1) I have calculated a route. How do I get the time my car will be on each segment. I think if I have the ordered segment collection and the time for each segment �?? it should not be too hard to get it. 2) I have a network and information about the time it takes to cross each segment in a different time in the week. How do I put this information into the network so the routing will take it in to account. If I solve these two questions and combine them I solve the problem. There is not to much more into the real problem, it is just a way to make sure two "cars" will not be on the same segment in the same time. Thanks

First, this is not really a railroad network but it show my problem in a simple way. About the static/dynamic network. With Historic/Live traffic (10.1) you can define what will be the speed on an edge sometime in the future. It usually comes from historic data or from real time data. In my case I would like to simulate it with data from the last train route (before the train really go). If train A crosses some segment between 10:00 to 10:15 in this time this segment is very slow to drive on. With both ways (Historic/Live traffic) I can estimate the delay for each segment for some time in the future. The problem is to take the data from the first route and translate it to delays in the future.

We have a rail network and a set of trains (A,B,C???) that should go from one point to anther (A train from a1 to a2, B train from b1 to b2 etc). The main problem here is that two trains cannot be on the same segment in the same time (even if the segment is long). Our idea is to find the path for train A. Then block all the segments that train A crosses in the time it crosses them before we try to solve the path for train B. The question is how to block the segments. Should we use barriers ??? they do not have time limit (as far as I know). Should we use Historic traffic or Live traffic? How do we translate the information about the route of train A into one of these ways before we solve train B. It is clear that we will need code but any hint will help. Thanks Mody

I could not find PythonWin on 10.1 installation DVD �?? is it there? In the help (http://resources.arcgis.com/en/help/main/10.1/0021/002100000021000000.htm) you have a link but I could not find it there too. In other topic in the help: http://resources.arcgis.com/en/help/main/10.1/0021/002100000022000000.htm the buttons of PythonWin is used. Where can I get it from and should I do this? Thanks

I have similar problem when running script tools not within desktop (stand alone application). The PointToLine is a script tool. Are you running from stand alone application? Can you run other (not script) tools. Can you run it (using code) within desktop? Mody

Hi All We are trying to run system tools that are really a python scripts from Desktop 10.1 and get an error about wrong paramaters. We are trying two methods: IGeoProcessor pgp = new GeoProcessor(); IVariantArray parameter = new VarArrayClass(); parameter.Add(@"c:\temp\ForRT.gdb\people"); parameter.Add(@"c:\temp\ForRT.gdb\people_point_line"); pgp.Execute("PointsToLine_management", parameter , null); or: Geoprocessor GP = new Geoprocessor(); PointsToLine pointsToLine = new PointsToLine(); pointsToLine.Input_Features = @"C:\temp\ForRT.gdb\people"; pointsToLine.Output_Feature_Class = @"C:\temp\ForRT.gdb\people_PointsToLine"; GP.Execute( pointsToLine, null); Both ways gives the same error. Can anybody help? Thanks Mody

Hi This is the example: http://resources.arcgis.com/en/help/arcobjects-net/conceptualhelp/0001/0001000002r6000000.htm I do not think it changed from 10.0 Have Fun Mody

Hi I am not sure if I did not understand the answer or you did not understand the question. Let me explain it again. I divide the area into 50 meters boxes. I need to know who many lines crosses each box. If I translate it to vector and I have 50X50 KM then I have 1M boxes and have to select 1M times the line layer to get the value for each one. That is why I need a way to make it using raster. I do not have any DEM here. Thanks Mody

Hi all I need some ideas on how to perform some analysis. Here is the problem. We have some GPS points of moving cars. The GPS is not accurate and the delta from the real location can be 50 meters or more. We create lines from the points. We might snap it to roads network but in some cases in city the points can snap to the wrong street. What we are looking for is places where the person drove only once (or only twice). Because the route is not accurate we must translate the lines into raster in some kind of Kernel Density process and then check the raster. The problem is that if we have two lines the raster value is higher than if we have one line but when we move away from the two lines value we get similar values to the one line values. Can anybody think about a nice way to do it? Thanks Mody

Hi Mike Thanks but the basic license you get as part of EDN is for the EDN period only. Do you have to replace it for all users once a year? What happened if you do not continue to be an EDN user? Thanks Mody

Hi Mike Thanks for the full explanation but the technical process is clear. The question is more commercial. If you are EDN programmer for organization and use Basic functionality only. Can you use this authorization string as many time as you like within the organization? Thanks Mody

Hi Jennifer, Thanks, now I understand. I was confused because also the dynamic layer is defined as esri:FeatureLayer. I join you opinion about Dominique's samples.... Thanks again, Miri

Hi again, I looked at the dynamicLayers sample : http://resources.arcgis.com/en/help/silverlight-api/samples/start.htm#DynamicLayerThematic and it looks like it also adds a FeatureLayer but instead of giving a Url, it uses Url="http://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer/dynamicLayer" and <esri:LayerMapSource MapLayerID="3"/> Which way is better? Thanks a lot, Miri
