Hi there, I am thinking of using Collector to collect data in the field, but I am not sure what base map I should use. ESRI provides lots of base maps with great cartography, but my concern is the projection. as you know, those ESRI base maps (maybe not all of them) are using Web Mercato Auxiliary Sphere (WKID: 102100) which used to be a very controversial projection (Google/Bing maps started using it) and is not very accurate. although it's well accepted by the GIS industry now, I am wondering whether or not it will cause problems when using GPS in the Collector? I don't know what kind of GPS my users will have on their devices, but we know all the GPS will use WGS84 datum. Web Mercato Auxiliary Sphere is using the same datum, will this guarantee there won't be any accuracy loss when displaying the GPS locations on the map? we don't really care about the accuracy to the true location, only relative accuracy to the map matters. I did some test using my phone, the result is not too bad, but don't know if that's just a individual case, or it's guaranteed to be working on other devices as well. I am in Australia, the most popular projections in my work are GDA1994_MGA (283xx) and GDA1994 Lambert (3017) Thanks, Simo

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

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

Will it be nice to have the above function in the Webmap in ArcGIS Online? I searched around and found this article in ESRI Knowledge Base: http://support.esri.com/es/knowledgebase/techarticles/detail/43075 but, contrary to what stated in the article, I found join via relationship class does not work in ArcGIS Online, it only works as a relate. A unique feature of join is the appended fields which can be used to symbolise the features and label the features. there are no appended fields in the service in ArcGIS Online, so I don't think the genuine join is working. There are some ideas in ArcGIS Ideas, but I don't know if ESRI is considering the fuction. let's promote them anyway if you think it's a useful function. https://c.na9.visual.force.com/apex/ideaView?id=087E0000000CxLr&returnUrl=%2Fapex%2FideaList%3Fc%3D09a300000004xET#sthash.8htTvKfH.dpuf https://c.na9.visual.force.com/apex/ideaView?id=087E0000000CxPF&mc=0
