Below a small example of a POST request. This did not work on my computer due to an authentication error, but that just might be my proxy (the server supposedly does not require a token (but you may in your case). More on getting a token here (include it in the params dictionary): ArcGIS Help 10.1 import urllib import urllib2 # a list of non existing object id's (to avoid deletion of features) oids = [37,101,462] ids = ",".join([str(oid) for oid in oids]) print ids # encode the parameters, only specifying the list of objectids (simple case) params = urllib.urlencode({'f': 'json', 'objectIds':ids}) print params # taking the sample HomelandSecurity URL (hoping this doesn't affect my visit to the DevSummit next year) queryURL = "https://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/FeatureServer/0/deleteFeatures" # use the request method on the urllib2 library req = urllib2.Request(queryURL, params) # forces POST request (deleteFeatures can only be done with a POST request) # get the response response = urllib2.urlopen(req) # assuming this query URL jsonResult = json.load(response) # do something with the response print jsonResults This will return a json list indicating the result of the deletion for each object id: {   "deleteResults" : [     {       "objectId" : 37,       "globalId" : null,       "success" : false,       "error" :       {         "code" : -1,         "description" : "Delete for the object was not attempted. Object may not exist."       }     },     {       "objectId" : 101,       "globalId" : null,       "success" : false,       "error" :       {         "code" : -1,         "description" : "Delete for the object was not attempted. Object may not exist."       }     },     {       "objectId" : 462,       "globalId" : null,       "success" : false,       "error" :       {         "code" : -1,         "description" : "Delete for the object was not attempted. Object may not exist."       }     }   ]} Kind regards, Xander ... View more

I´m glad you figured it out! ... View more

Did you get any error message? How are your geoprocessing environments set? What spatial reference are you using, and what did you define as cell size? A little more info could help... Kind regards, Xander ... View more

This is a very good suggestion (+1 for that), if you are the "owner" of the data and have administrative right on the service... Kind regards, Xander ... View more

Normally services are configured by default to return only the first 1000 records. You can change the configuration of the service to return more features or if you don't have access to this configuration you can use for instance the REST interface to query records based on for instance the ObjectID: objectid > the highest objectid from the previous query. The query below queries the features starting from a certain objectid: Query Features (Earthquakes from last 7 days - Earthquakes/EarthquakesFromLastSevenDays) Using some Python code you can translate the url query to a featureclass: import arcpy fcout = r'path to your output featureclass' url = 'http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Earthquakes/EarthquakesFromLastSevenDays/FeatureServer/0/query?objectIds=&where=objectid+%3E+224354126&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&outSR=&returnIdsOnly=false&f=pjson' fs = arcpy.FeatureSet() fs.load(url) arcpy.CopyFeatures_management(fs, fcout) You should start with querying the entire service, store the result as featureclass, determine the highest objectid, and use that objectid in the next query. At the end merge the featureclasses... Kind regards, Xander ... View more

Hi Victoria, Sounds like an Esri grid... You can read more on Esri Grid formats here: ArcGIS Help (10.2, 10.2.1, and 10.2.2) Please note that a raster in Esri Grid format consists of various files and folders. There will normally be a folder with the name of the raster, which contains like 5-7 ADF files and you will have an info folder with arc*.* files. If there are not complete it is possible that you don't have all the files required for ArcGIS to recognize it as a raster. Kind regards, Xander ... View more

Hi Rosa Maria, Primero que todo, bienvenida a GeoNet y seguramente vas a aprender mucho en tu curso de SIG... Now back to English, this discussion that you posted sound like something you could post on your profile page by completing your profile:rosa maria cadena Kind regards, Xander Bakker Esri Colombia ...

I don't have the parameters for you, but maybe this site helps you in defining the parameters: WGS 84 / UTM zone 16N - EPSG:32616 Kind regards, Xander ... View more

What format is you DEM in? Could you specify the file name, format and source of the information? Kind regards, Xander ... View more

I suppose you are using the "Delete Features (Data Management)" tool to delete the features and the expression you showed is the one specified in that tool. When you use python the syntax can be different for the expression than the one you use in the dialog manually. In this case you specify "!LAST_EDITED_ON!" as the field. This produces an invalid syntax in Python. If you look at the Help, and scroll down to the second code sample, you see that the field is specified differently. They also use the arcpy.AddFieldDelimiters(FeatureClassOrTable, FieldName), to make sure that the field is addressed correctly. Since you didn't specify the rest of the script it is impossible to verify if the error is indeed caused by this. You could try changing the code to: fc = r"Path to your featureclass or table" fld = "LAST_EDITED_ON" fld_ok = arcpy.AddFieldDelimiters(fc, fld) expression = long(float((arcpy.CalculateValue_management(time.mktime((datetime.datetime.now()              + relativedelta(years=-10)).timetuple())))[0])) - long(float((              arcpy.CalculateValue_management(time.mktime(time.strptime(fld_ok, "%x %X"))))[0])) > 0 Not sure if this will work though...
