I am trying to select zonetypes (eg forest, agriculture) within  a municipality and to show the area of each zonetype in this municipality. I am doing this in ModelBuilder and will export it to a python script later on. I am stuck with following Points How can I tell ModelBuilder to perform the task on the municipality I click in with my Cursor? I heard Feature sets are helpful but I don't really understand how they work and how I must implement one as a pointer How can I get the area statistics? I thought by using the Calculate Area tool. This would create a new feature class.Another option would be exporting the selected data as a table and perform a summary on it. However, these two ways do not work with the "select layer by Location tool" as this requires a layer file as input This question is also posted here: arcgis desktop - Select by point using ModelBuilder? - Geographic Information Systems Stack Exchange ...

Hello I created routes with the "Create Routes Tool" in ArcGIS 10.2.2. The route persists of rivers for quite a large area. The flow direction of the rivers are either "1" which means flow direction in digitized direction or "2" = flor direction against digitized direction. This seems to be correct for all routes. When I open the "Edit Sketch Properties" I see that the M-Value however is not correct for all routes with the value 1 = flow direction in digitized direction (pic with red highlighting). I Need the M Value to be 0 at hashtag 0. The highest M Value should be at the highest hashtag hence the M Values should be switched (see pic with green higlighting). When I flip the routes, I flip the  whole direction which I dont want as the direction is correct (blue highlighting). I only Need the M-Values to flip, not the #-values. I can do this with right click on the route --> route measure editing --> set distance. However, this is only possible for one route at a time and as I have many routes I am looking for a solution to do this automatically. Is there an update m values tool or anything like this in ArcGIS? I could not find anything. ... View more

I want to create a python script (ArcGIS 10.1) where I loop through a GDB with several feature classes  and select all the fields which are of text type and convert them to float type. I always want to skip the first 10 and last 2 fields of each featureclass as they actually are supposed to be of text type. I am not quite sure how to do so.. I guess FeatureClassToFeatureClass_conversion does the trick but I am a bit lost. This is as far as I got: (I asked the same question on Stackexchange as I need an answer asap: http://gis.stackexchange.com/questions/150723/convert-field-types-in-gdb-with-python) # Import system modules import arcpy from arcpy import env env.overwriteOutput = True # Set environment settings env.workspace = "D:\Test\2011_LongNames.gdb" inFeatures = arcpy.ListFeatureClasses("*") outLocation  = "D:\Test\FLOAT.gdb" outName = ??? same as inFeature field_mapping = ???? part where it converts text fields to float fields listFCs = [f.name for f in arcpy.ListFields(env.workspace)] listFCs = listFCs[10:len(listFCs)-2)] for fc in listFCs:     arcpy.FeatureClassToFeatureClass_conversion(inFeatures, outLocation, outName, field_mapping ) ...

Hi I have many tables which I need to join to a Shapefile. Each table has to be joined to the shapefile seperately and then must be exported into a file GDB. Anyone knows how to do so with python? Is there a way that the code runs automatically through each table in the folder and joins it to the shapefile, exports it as FC in the GDB, gives it the file name of the table, then removes the join and joins the next table to the same shapefile? I work with ArcGIS 10.1 I came across this site ArcGIS Help 10.1 and also ArcGIS Help 10.1  but I have no clue how to get started to be honest.. ... View more
