    Network Analysis :D
  1. I think you should use cursors like this input_fc="fc" field = "buffer_value_field" output = "fc_somewhere" output_temp = "fc_somewhereElse" cursor = arcpy.da.SearchCursor(input_fc) for row in cursor: arcpy.analysis.Buffer(input_fc,row.getValue(field),output_temp) arcpy.management.Append(output_temp,output,"NO_TEST") arcpy.management.Delete(output_temp) it does not work in the append process, I just made a conceptual example for you
  2. first thing on my mind is: 1 - convert end of your line to point - (arcpy.management.featurevertiestopoints) 2 - add points based on function(length, deflection) which based on last point on OID list shape@XY it calculates new XY maybe you can do it with tables only 3 - create a line based on points created in last step and then add it to first line you had 4 - do step 2 and 3 over and over again till end of your list
  3. I didnt check your file, but the solution is sth like this fc = "your_featureclass" fields = ["road_name_field"] cursor = arcpy.da.UpdateCursor(fc, fields) for row in cursor: full_name = [] full_name = row[0].split(" ") road_type = full_name[-1] if road_type = "ST": full_name[-1] = "STREET" elif road_type = "RD": full_name[-1] = "ROAD" result= full_name[:-1] result.append(full_name[-1]) row[0]= " ".join(result) cursor.updateRow(row)
  4. Dear Friends, Me and my colleagues are trying to make an application for routing purposes. This application has to be in a mutual transaction with a GPS tracking device obviously. Here come the issues we encounter 1. We are getting the login data but after that we need to send response to device with a format that device can verify server and then send actual GPS data to server. 2. We are not able to send login data to that device so that's why device not send us GPS data. 3. Login Data we are getting is like :- 2323101501f357367031649441529625060. 4. We are not getting further process what to do to get Device GPS data to our server. We have asked for the GPS device support, no useful information but offering their own portal. and here is the code developed for this transaction : package com.trackit; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.ServerSocket; import java.net.Socket; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; public class ServerListener { public static void main(String[] args) { new ServerListener().startServer(); } public void startServer() { final ExecutorService clientProcessingPool = Executors.newFixedThreadPool(03); Runnable serverTask = new Runnable() { @SuppressWarnings("resource") @Override public void run() { try { ServerSocket serverSocket = new ServerSocket(5094); System.out.println("Waiting for clients to connect..."); while (true) { Socket clientSocket = serverSocket.accept(); clientProcessingPool.submit(new ClientTask(clientSocket)); } } catch (IOException e) { System.err.println("Unable to process client request"); e.printStackTrace(); } } }; Thread serverThread = new Thread(serverTask); serverThread.start(); } private class ClientTask implements Runnable { private final Socket clientSocket; private ClientTask(Socket clientSocket) { this.clientSocket = clientSocket; } @Override public void run() { System.out.println("Got a client !"); try { BufferedReader reader = new BufferedReader( new InputStreamReader(clientSocket.getInputStream())); String clientData = ""; clientData = reader.readLine(); String hex_value = asciiToHex(clientData); System.out.println("Hex Value :-"+hex_value); } catch (IOException e) { e.printStackTrace(); } } private String asciiToHex(String clientData) { char[] chars = clientData.toCharArray(); StringBuffer hex = new StringBuffer(); for (int i = 0; i < chars.length; i++) { hex.append(Integer.toHexString((int)chars[i])); } return hex.toString(); } } } Any kind of tips and help is appreciated. Kindly Regards
  5. If size matters and the shape is not complex, give this a try: Maximizing(proportion of polygon(i).boundary(part).length which falls within a close buffer around base.polygon.boundary to polygon(i).boundary(full).length)
  6. Hi, Create mode 'c' Import: Tools > Shape File to Emme Conversion Create something like myCity.in and myCity.db after Exporting copy myCity.db into database folder and rename db file to Scenario1001 then open up Modeller and find Process base network transaction select the new Scenario and myCity.in and RUN back to Desktop and worksheet about exporting, search in modeller
  7. dear stephenhann, please post your sample raster map here and let us take a look regards,

  10. What do you want to achieve by this? a little explanation about your purpose would help us understand your problem
  11. Welcome dude, I'm interested in spatial correlation methods, please share some of your knowledge with us many thanks
  12. I'm not sure if this is the solution some times addresses in identify server and pools change, and you have to run post installation again for checking the host addresses. and even go for xml files for corresponding addresses again. in some cases post installation does not work properly. very unstable software
  13. dear saifkhalidrao, if you simply install bluestacks software (its free) you can run android applications on it. about this specific application i dont know if it has a windows version or not.
  14. ESRI Certification was created as a one source stop for all your ESRI and GIS examination, certification, or interviewing test question needs. The application is also a resource for any students looking to obtain a GIS degree program. This application contains over 300 ESRI test questions split up between ArcGIS Desktop and ArcSDE This application contains over 225 desktop questions. Questions are randomly seeded every time so you get a fresh test every time. The application keeps track of you correct answers rating. You can adjust the number of questions in case you want to take shorter test. This is the lite version and is supported by ads. If you want the full question bank which also includes ArcGIS Developer and ArcGIS Server questions, download the non-lite version. https://www.dropbox.com/s/oysskpqt1xspsto/com.gispertification.esri.quiz.lite_1.0.apk?dl=0
  15. dear baz_dam, explain more please
