Hi Shiva, Can you please help me to setup development environment using Angular 6 and 3.X ArcGIS API for javascript in a step by step points.

Along with downloaded data, it was mentioned that the projection is 27700 projection. i am sure about this.

Thanks Dan Patterson and Sangeet Mathew for your response. I appreciate that. It's not working for me.may be i am doing something wrong while creating mosaic dataset. I am using ArcGIS Pro 2.3.3. I downloaded images(15 images) and building footprints from Ordinance Survey, for UK Location. these images are freely available. Original downloaded images were in ECW formats. So converted them into .tif. and then made mosaic dataset. after this i am trying to create training dataset using this mosaic dataset. But i am able to create training dataset from individual .tif files. since i have 15 images, so i thought to mosaic them, into one, then at one go i would create training dataset, but it did not succeed. When I create training dataset from individual .tif files, it will generate into 15 diff folder, so then later if i want to combine all training dataset into one, naming convention and their meta data i will have to manually do it. Projection - 27700.prj used. there was no projection defined to images and vector data. so i defined the projection from Define_Projection tool. If there is anything wrong here, in my process, please point me to correct one. Thanks.

Hi Folks, I am trying to create training data set for deep learning, using "Export Training Data For Deep Learning" tool. Input raster - i am giving in this tool is Raster Mosaic Dataset (created by referencing tiff images located at location in my machine). This mosaic dataset in created inside FileGeodatabase. Input Feature Class - is polygon feature class - which has building footprints. Output image format - TIFF Meatadata format - PASCAL Visual Object Classes. This tool run successful without any error. at output folder location it creates following folder structure also, images labels esri_model_definition.emd esri_tile_lines.json stats.txt But there are images inside 'images' folder and there are no xml files inside 'labels' folder. Where as in other scenario, where If i give input Raster - as single tif file. it works properly, and creates image chips and labels. What might be the reason? doesn't this tool support Mosaic Dataset ? I have large areas, so i mosaic-ed the images and then i am trying to create training data set. Do i have to run this tool multiple times for multiple raster images? Sangeet Mathew‌ Thanks. -- Ravindra Singh

Hi Shankar, I have few queries: Can i create custom GUI for my custom Checks. Is there any other ways to use my custom checks other then first registering .dll and then every time user wants to use, he has to know the GUID of that custom check to mention in custom UI. - Why i am asking this because, in some of end user does not have Admin rights, so they can not register the .dlls. why can't cusotom checks be used like the way esri supports custom Addins? - Thanks Ravindra singh

Does ArcGIS API for JavaScript 4.9 supports DOJO2? Can we use / install Dojo 2/3/4 Typings? if not what is the plan in future. if yes, is there any link for getting started using DOJO2.

thanks Nielsen, this is actually what I thought of. I am here kind of confused and stucked. I am developing Cross platform app. which works on both Droid and iOS, with single code base. for that I am working on Xamarin.Form Components. in ArcGIS runtime SDK 100.1.0 for .NET There are two Namespaces e.g. Esri.ArcGISRuntime.UI.Controls -->Esri.ArcGISRuntime.UI.Controls.MapView. This above one has the property - as CalloutStyle. Esri.ArcGISRuntime.Xamarin.Forms. --> From here I am using, Esri.ArcGISRuntime.Xamarin.Forms.MapView But this doesn't have it. Can you please suggest here, or share some sample code to set the Button inside the Callout on Esri.ArcGISRuntime.Xamarin.Forms.MapView's Tap Event. Best Regards, Ravindra

‎09-21-2017

Hi, Can you please share the whole code, to get similar kind of output, I also want to create a callout with Table like GUI and close button at the top of the callout. Thanks.

‎09-21-2017

Hi Here is the Solution:: Call this method inside your button click event... private async void LogIn(string username, string password) { btn.IsVisible = false; aiLogin.IsRunning = true; if (string.IsNullOrWhiteSpace(username) || string.IsNullOrWhiteSpace(passw ord)){ ShowError("Invalid username or password"); return; } var url = "https://yourorg.maps.arcgis.com/sharing/rest"; try{ App.UserCredential = await AuthenticationManager.Current.GenerateCredentialAsync(new Uri(url), username.ToLower(), password) as ArcGISTokenCredential; //Connect to the portal ArcGISPortal portal = await ArcGISPortal.CreateAsync(new Uri(url), App.UserCredential, CancellationToken.None); //Get current portal user App.CurrentPortalUser = portal.User; } catch(Exception ex){ string str = ex.ToString(); System.Diagnostics.Debug.Print(str); return; } }

Hi Folks, We want to develop Map based Mobile Application for iPhone and Android both. Few functionalities are as below:: Basic Map Navigation Routing Search capabilities on diff layers Security: only authenticated users are allowed to download and install this app. Secured Login into Application Access of secured ArcGIS Map Services Integration with LDAP / Outlook to search employees and their details. NOTE:: There are 2 developers in my team, one has experience in Development in Android based Mobile App. No one has Experience in iOS Dev, We don't have Mac Platform ready as of now (We need to buy if required). There are many options available such as: Go for ESRI AppStudio; and then further customize in QT Editor- We are new to this, we need to learn this. Go for Hybrid App development using (Cordova, PhoneGap etc.)- We are new to this, we need to learn this too. Go for Xamarin for cross platform development.- We are new to this, we need to learn this too. Go for Native Application development separately each for Android and iOS - Here we have one developer who has exp in Android, but - We are new to iOS, so we need to learn this too. I have gone through the GUIDE Line available on the ESRI Blogs Development strategies for targeting Android, iOS, and Windows Phone . So please don't suggest me on broad point of view. e.g. consider your developers skills, targetted users. budget etc. i want suggestion from technical, performance, and future compatibility point of view. Based on the description I have provided you above, suggestion are required from your experiences.
