I have started learning Python for ArcGIS last week and have a simple script to reproject all the datasets in a folder. The script says "syntax error- invalid syntax" but I can't find anything. Can someone please have a look? It seems something very basic but I'm pretty new so I don't see it at the moment. Also running this in ArcGIS prints "failed" right away. And the files are in place in the right folders. I have already checked.   import arcpy ... sourceWorkspace = "C:\\Users\\tx8p90\\Desktop\\Lesson2" ... targetProjection = "C:\\Users\\tx8p90\\Desktop\\python excercise data\\Lesson1\\contourlines.shp" ... listDataSet = arcpy.ListDatasets(sourceWorkspace) ... try: ...     for x in listDataset: ...         outputDataset = sourceWorkspace + "\\projected_" + x ...         arcpy.Project_management(x, outputDataset, targetProjection) ...         print "Reprojection successful" ... except: ...     print arcpy.GetMessages() ...     print "failed" ...

I have a very similar question- Can maps/layers created in ArcGIS desktop be opened in the online Version? I uploaded one of my ArcGIS desktop layers online. It was successfully uploaded but I see only one option to open it 'Open with ArcGIS desktop'. Can't I open it with online map viewer? Or is this too great a Task for the fragile online platform? lol ... View more

I want to create a walkability network for the city of Dortmund such that it includes all the line features that are walkable like footways, pedestrian streets etc. I downloaded OSM shape file from Geofarbrik website and now I see that there are a lot of inconsistencies in the roads data. Lots of streets are not classified as highway or footway or anything. Lots of footways are not present at all. Names of streets are missing and many more things like that. Now ofcourse I am aware that this is a consequence of using open source data and we have to deal with such inconsistencies that are a part of publicly sourced data almost always. But I just need to know if there is a better way to create a such a walkability network which could achieve some standard of accuracy rather than now editing all of the data by myself by adding or correcting all walkable polylines in this network using may be google maps or something to see if there is actually a footway in a particular street or not or if its walkable or not. That is gonna be one hell of a work. Phew! ... View more

I created a choropleth map for Portland showing distances from the city center. Now the problem is after I set any symbology to the map, it dissapears when zooming in after a certain extent. Show map at all scales option is checked in the layer properties. So I don't understand what else can effect this dissapearance. It is a problem for me because the same thing then happens in layout view and I cannot print out my maps with zoomed in view. Please if someone can think of a solution it would be great. ...

Hi, I creataed a simple service layer polygon in network analyst(ArcGIS Desktop 10.2) with no heirachies set in the street network. Now I don't udnerstand why is this polygon created along some particular streets? Why isn't is properly spread out? For example why doesnt the polygon cover the areas/streets I have marked in red?(obviously those marked areas are also within 1km atleast, then why not form there?) The impedence is 1km and 2kms respectively. The streets are also well connected individual line elements as you can see the junctions. Thanks alot! ... View more
