Hi All, I am about to develop a simple map application for an organization on a pro bono basis. The organization is under the category of Trust / Society / NGO with reference to 80G of the Income Tax Act, 1961 of India. I am planning to develop the web map by using ESRI Java script API + Database +Django Rest framework. Plz note: 1. The NGO does not own an ArcGIS Server and is not intending to buy one. 2. I am from India and its an Indian NGO. 3. The website is not for any commercial purpose. 4. The web map is just a small component in the website - for data visualization. Given these conditions, is it legal to develop the web application using ESRI Java script API ? Recommendations / answers from ESRI's representatives would be highly appreciated.

Hi Everyone ! We are facing some issues with our application. Technology stack involved: ArcGIS Server 10.3 Esri js api 3.13 The legend that comes with our print task is not dynamic. We are using a specific template for our print task. Ex: This is the result from print task. The Extent at which the print task was triggered: We tried fixing this issue by setting legend properties in the items tab by enabling the option --"Only show classes that are visible in the current map extent" . But, the option gets disabled automatically. Kindly suggest your opinion / work around in fixing this issue.

Hi Amal, If your requirement is to see the bounds & attributes information in a readable way , i would suggest you to convert from SHP to geojson. If that is the case, you dont really need arcobjects , a simple web application would do.

Hi Nigel, You can use the reorderLayer() method of the map class.

As mentioned by Jayanta Poddar , You can query the REST Services using Query Related tables. Ex: Query RelatedRecords Example Query performed on the REST Service. and the Relationship query can be performed in the js api using the "RelationshipQuery" class

Hi Wi, This is a sample code , that does the job . You can still modify it , to make things efficient import arcpy from arcpy import env #Configuration goes here vill_fields = ['Shape_area'] town_fields = ['Sum_area'] env.workspace = r'D:\Geonet\geodbase\village.gdb' village_List = arcpy.ListFeatureClasses() #pushing all the fc's into a list town = r'D:\Geonet\geodbase\town.gdb\base' def findTotalArea(fc): with arcpy.da.SearchCursor(fc,vill_fields) as cursor: varea = 0 for row in cursor: varea = varea+row[0] return varea for fc in village_List: farea = findTotalArea(fc) with arcpy.da.UpdateCursor(town,town_fields,"town_name = '" + fc + "'" ) as cursor: for row in cursor: row[0] = farea cursor.updateRow(row)

Hi Shikhar, Case 1: If the services that you are accessing are known to you , you will probably know the services that are published. So , you can query them using urllib/ urllib2 like : import urllib2 url = "http://YourUrl/rest/services/sample/MapServer/0/query?where=1%3D1&f=pjson" data = urllib2.urlopen(url).read() print data If you are getting results , then it is not secured. If you are getting result as '{\n "error": {\n "code": 499,\n "message": "Token Required",\n "details": []\n }\n}' , or any such error , then it is secured. Case 2: If the services that you are accessing is not known to you and you can do a simple analysis using the following URL: http://YourURL/rest/services/?f=pjson and conclude if the services are secure or not secure.

If you can share the code , we can try to figure out whats going wrong...

I am really sorry , the above mentioned code will work only if you are creating your own application. Assuming that you are using AGOL with an organisational account, you can set the hyperlink to a specific layer by the following method while creating the specific web map. Step 1: After adding the respective layer while creating the web map , Select the specific layer and choose configure pop-up Step 2: - Select "A Custom attribute display" under display. - click configure Step 3: - select the hyperlink option. - set the URL with the specific field ( http://www.yourwebsite.com/{specificField} ) - set the description , click ok - Save the Pop-up. Now , your popup will have the specific hyperlink.

Hi Chukwuemeka, From the comparing the input table and output table , it is hard for me to find a condition using which the output table is generated. If you can explain the condition & logic involved in detail , it will be helpful.

‎05-07-2015

additionally you can cross check by : with arcpy.da.SearchCursor("SR2",['SHAPE@X','SHAPE@Y']) as cursor: for row in cursor: print row[0] print row[1] It will print : -4.810426852 52.654352152

Hi Chris, try the following code : import arcpy inputSRS = 'Projected Coordinate Systems/National Grids/Europe/British National Grid' # Projected outputSRS = 'Geographic Coordinate Systems/World/WGS 1984' # Geographic trsOut = 'OSGB_1936_To_WGS_1984_Petroleum' srIn = arcpy.SpatialReference(inputSRS) srOut = arcpy.SpatialReference(outputSRS) pt = arcpy.Point() ptGeoms = [] pt.X = 210000 pt.Y = 310000 ptGeoms.append(arcpy.PointGeometry(pt,srIn )) arcpy.CopyFeatures_management(ptGeoms, 'base') arcpy.Project_management('base',trsOut, srOut) It will first create a Feature named 'base' with input SRS and then creates your output feature with output SRS. You can set the environment to save the output in a specific location.

Hi Chukwuemeka, If these are the attributes of a feature class , the following code might help : import arcpy fc = "c:/data/base.gdb/construct" fields = ('TestDate', 'Construction') with arcpy.da.UpdateCursor(fc, fields) as cursor: for row in cursor: if row[0] < row[1]: cursor.deleteRow () Hope you would find this useful.
