i'm starting a web app using ArcGIS WAB, i want to import my data without using ArcGIS Server, from Geoserver or PostgreSQL is it possible?

Sure just create a Web Map on AGOL that uses your ArcGIS Services and then have your WAB App use that Web Map.

I already made an app using WAB, but i want to load my data from Geoserver to this app

A WAB app uses a Web Map and what ever data that is in that Web Map. So if you want your data to be available in WAB then you should add it to the Web Map that your WAB app is using. If you want to add your data at runtime to the App then you use the Add Data widget.

so if i want to use WAB app, i can only import my data from ArcGIS Online? i downloaded the app, and i wanna change the code so i can import data from Geoserver without passing my data to ArcGIS. is that possible?

You will not be Importing your data to ArcGIS Online. You will only be have the Web Map on ArcGIS Online point to the data on your ArcGIS Server (there is a pretty big difference). WAB is NOT designed to make direct use of your ArcGIS Server services directly. There are some custom widgets Like the Local Layer Widget that extend WAB to be able to do this but I have personally quit using these some time ago in favor of just doing it the way esri designed WAB to work (meaning build a Web Map on AGOL that uses your local ArcGIS Server services).

Hi,

Interesting debate.

I have here a similar issue: I want my Web Application to use data from Google Map (just because is more comprehensive), in particular POI (point of interests) based on a location provided by the user. Download the data and store it somewhere beforehand is not an option as I would need a massive amount of store resources so I would need in such a way to trigger a script to download the data from Google Maps based on the point picked by the user.

I already have that a Python script to do that but I don't really understand how to integrate that script into WAB.

Any advice?

Many thanks.

Alberto,

I want my Web Application to use data from Google Map

This would be a violation of Google Maps Terms of Service. You can not use Google Data with any other map then Google Maps.

Hi Robert,

Thank you very much for your response.

is it not possible to use Google Maps data out of Google Maps even if you pay for that?

Not that I am aware of, but that is a question for them.

Hi Robert,

Thanks for your response. After researching a lot is not clear for me if using data from Google Map onto ArcGIS web mapping is allowed or not, so I forgot that option and I decided to use data from OpenStreetMap instead.

I created a python script to download POIs (points of interests) from OSM, which based on a given pair of coordinates (x,y), all the POIs within 4 km from the coordinates are downloaded. The output of the Python script is a Geojson file with all the points.

I want to use this script in my ArcGIS Web Application. Given a pair of coordinates from the user, the python script would be triggered in order to download the data from OSM. After that, the data would be display in the Web Application.

Do you know how can I do that without ArcGIS server? I called esri and I cannot afford it at this stage, as I am just prototyping.

Many thanks.

Does the python script return a string or a url?

Hi Robert,

Thanks for your answer.

The python script return a geojson file.

Alberto,

Well that makes things VERY difficult. That means that the python script would have to be converted to a Geoprocessing Service on ArcGIS Server so that the JS code could call it and then the file would need to be hosted by a web server to be available as a url so that WAB could consume it. Sorry to say that this is advanced GIS Developer work.

Hi Robert,

Yes, that was the solution that came to me first, deploy the Python script

as a Geoprocessing Service and call it from my web Application via ArcGIS

REST interface. The problem with that approach is that I need ArcGIS server

and it is quite expensive.
