Hi Ismael, The repeat function sounds really interesting. I really like the smart form feature of Survey123, but my situation is like what you said “ want it all, something that runs anywhere…”. Instead of asking people the location, I know where the property is and have some baseline information of the property, now I need to do an assessment/inspection on it. so I kind of need to identify the property and then bring up the question forms to start the assessment/inspection. Currently, I am using Collector to do it, it works, but the form in Collector is not as ‘smart’ as in Survey123, it does not support the basic logic like “Relevant” function in Survey123. I even don’t know if my case should be classified as “form-centric” or “map-centric”, we do have lots of forms, but the forms are designed for individual properties which has a specific location!

Good stuff. just one question, how well does Survey123 support related tables for features. I am thinking of using the smart form for asset inspections. Cheers,Simo ... View more

Hi Miaogeng, Thanks for referring me to the blog. it sounds like if there are no datum transformation involved, assuming the GPS accuracy is acceptable, then the GPS position and the map should match. Miaogeng Zhang​ Gordon Sumerling​ I don't know what device the users will have at the end, because they are from different government agencies, I don't think they will have uniform devices. maybe some use android phone, some use iphone&ipad, windows phone when collector is available on that platform. I hope we don't need external GPS units, but I'll see after the first field test. Simo ... View more

have you seen this post before, it seems only Pro supports python 3.4. ArcGIS Desktop and Server (AGOL is server)  only supports 2.7.7 Python in ArcGIS 10.3 ... View more

Hi Ron, Thanks for your reply. let me clarify my situation, I am NOT going to collect the information of the GPS location, instead, I am using GPS to "identify" the properties and assess the properties. so knowing where I am on the map is quite important and the more accurate the better I reason I raise the concern was that I had a thought on GPS maps then I did a bit Google research on it. I can assume the GPS receiver is always giving me the right coordinates (lat/longs or other units in UTM projection). but the 2D map I am using to show the GPS dot is a result of particular projection, which is based on a datum and a projection method. by this point, maybe the question should really be: is the GPS and the map I am using are using the same datum? because I think,  if the datum is the same, the actual lat/long in two systems (GPS and the map) for a location on the earth is the same, they should match. in definition for WGS84 and Web Mercato Auxiliary Sphere, it seems the datum is the same, so maybe it should not be a question... if I am using  another Geographical Coordinate System in my map, there may be a problem, the GPS location on the map can drift away (for example, I am standing in a property, but the GPS shows I am standing out of the property on the map) I am curious what map projection do they use in the commercial GPS Unit in our cars. Hopefully I am not making an obvious thing too complicated. I am not a surveyor, they should know these things better. ... View more

For application authentication, instead of using AGOL account (User logins), you can use application ID to and App secret to get a token to access the content shared with the app developer (with an AGOL account). this is convenient when you are developing an app to users who don't have AGOL accounts. So I think you have to use the token in your application which AGOL will recognise, because you registered the application. ... View more

Hi Robb, I don't know how you can auto-populate the facility ID in the related table using relationship. basically, the only thing will be populated in the related table, when you add a record, should be the GUID which is the key linking to the GlobalID in your feature class. So the point is, the table only relates to the feature layer, the relationship won't pre-populate / auto-populate any fields in the related table.Robb Hodges  Cheers, Simo ... View more

I don't know how hard it is to allow the users to choose which camera app to use in Collector, maybe an option in Collector settings? I am not a IOS developer, I don't really know if it's possible or not.Russell Roberts​ ... View more

Hi Tom, Polygon filling is tricky in AGOL. I used hatch and crosshatch in my feature layer, then I  published the map to AGOL, I found the crosshatch simple was missing in the Webmap. But if I view the map from Collector I can see the crosshatch symbol. Anyway, there's no way to select a hatch filling in AGOL. Point symbol is much easier, you can just use simple markers from the truetype fonts. Hope my experience is helpful for this issue. Cheers, Simo ... View more

It seems there's no way to avoid this. I had a discussion with a peer user, this is the reason for him to stick to ArcGIS mobile on Trimble. Hope an ESRI employee can clarify this for us. ... View more
