Situation: I want to determine if I can aim an antenna at a satellite from a given location and still receive satellite signals without surface obstacles (e.g., mountains) blocking the antenna. The antenna azimuth would be 146° (magnetic) and the antenna elevation would be 19°. Question: I believe the Skyline Tool holds the answer, except that I do not know how to account for the 19° elevation of the antenna within the tool. I've attached a sketch of what I think may hold the answer: taking the sin of the antenna angle and the distance to the nearest mountain, determine the elevation in meters that the antenna must clear and compare this to the height of the peaks. The problem is that foreground foothills and lesser peaks may still obstruct the angle of the antenna, and I want to conduct this exercise on more than one peak, but all surrounding surfaces from 140° to 150° (magnetic).

I have raster substrate. On top of it placed polygons with height in their attributes. I need to detect zone of viewsed from arbitrary point. The problem that all tools work only with rasters. But my object is polygons. Example of my data. I also need to way set angel params and height of point. Let's image point is Radar station and I need understand what territory is viewable.

Thanks! I will reread docs. But if I will storage rasters in raster mosaic in FS should I use SQL for storage metadate? I understand that I can put some meta-date in raster mosaic, but in our case we will have next meta date: -date -time -satellite type -status (already loaded/processed) This meta-date I will take from another DB and some of them from text files. By this meta-date we will plan to do query from web-portal. For my regret I have not enough experience to create good architecture. Could you explain me best way to do it's in my situation. Every images would be 100-150 MB size in JPG\JP2 format. Every day we will plan to load in 10-20 images. Also could you explain what data usually storage in SQL if biggest part (raster data) are usually storage in FS.

We would use ArcGis for Server for creating Web Portal. On the portal user should be able to query satellite images. And every image should display on map. As I understood we do not need to store rasters in SQL DB and should use filebase system. But would we have any troubles with multiple access from web if for example 10 or 20 people would request same image mosaic? I have heard about some file system locks or something like it. Also how to manage in filebase db attributes? Can I do select and insert operation from script/ written from scratch app without running ArcGIS. The problem that I can't image how to work with filebase system.

Could I use MSSQL 2012/2014 with ArcGIS Server 10.2 with SDE to storage rasters? The docs says only about Win 2008 R2 Server? > If you are making a purchase/no-purchase decision based on this information, I would suggest you verify this with Esri just to be safe. How can verify it?

Yes. We have ArcGIS For Server for workgroup, but we need to create raster mosaic with thousand of rasters. The limitation of SQLExpress is 10GB. End I have got next questions: 1. Do license allow us to unde SQL Standard instead of SQLExpress? There is no problem with limits of connection and available cores. We just need bigger DB 2. If license do not allow to use it, is there any restriction, that would lock ability to connect with SQL Standard? We want to test it at first, and only then think about can we buy it or no.

I know that ArcGIS for Server for workgroup can work only with MSSQL Express. But is it's possible co connect with full version of MSSQL? I need to test how it would work with big DB.

Hello! At current moment if we need add rasters to mxd files and then make service from it, then we can get data from this service on web-map. The problem that I can't add rasters to mxd by hands. The system should automatically get new data from server, and then user via web-interface should be able to access to this data. I have heard that I can use raster catalog to it, and (as I heard) I would not need to restart service to get access to new data. Is this right way? And where I can get docs/information how it's can be done? example: operator load data to DB user can do search of data in web-interface, and service should not be restarted every time when I add new data.

I need to setup at Python script list of fields for processing. There is option with name "group_field" Here is needed string: arcpy.MinimumBoundingGeometry_management(inFeatures, outFeatureClass, "CONVEX_HULL", "LIST") so after LIST I should specify the fields. But I don't know how. I tried to do: arcpy.MinimumBoundingGeometry_management(inFeatures, outFeatureClass, "CONVEX_HULL", "LIST", "cModelTxtName, tSessionTime, dSessionDate, cDataFileName, cProcLevel") But I got error: arcgisscripting.ExecuteError: Failed to execute.

I spend few days in attempting to get silverlight app work with ArcGis Server 10 sp5. The problem in that after compiling new silverlight project I got only blank screen if I use ArcGis Service. If I set up link to ESRI public service I see the map. I tried to run demo JS app with same connection string to service, and it's work well. I tied to do full reinstall of service, but there are now result. I can access to my service via rest protocol, and I see that it's work fine. The problem is only that Sillverlight app do not show any layers. When I used 9.3.1 server all worked fine. And I did not changed nothing in Visual Studio settings. Only path to new service. I tried to build app on server with silverlight viewer, and it's work fine, but it's failed when I try to compile it's as SL project. Silverlight viewer is work fine for me! The problem is only with App done in VS2010. Who can help me? I tried to googled, but I have found only few mention about this problem.
