In either case, the GPS values and image direction are stored in the header image file, assuming that the iOS or Android settings are correct to enable this. It is still quite a chore when you have many photos to rename. The SDE stored image remains linked to the online map and the images downloaded from the iOS camera roll are stored unlinked on your network using the standard iOS naming. This still gets stored in the SDE server with the rest of the new point information, but also allows the ability to download the photos from the camera roll in the traditional way. When attaching the photo in Collector, we choose the option “Choose From Library”. We have worked around this by adopting a methodology where we always take the photo on the iOS device using the standard Camera App on the device, which sends the image to the Camera Roll. Collector should provide the option to store the photo to the internal device camera roll, even if it’s not the default setting. Retrieval of the photos from the SDE server usually requires higher level GIS support. I agree that this part of Collector can sure be improved. Geotagged information (GPS location, image direction) For example, the site ID and the date/time.ģ. Having the photo names associated with date/time or even better, allowing the user to set how the name is stored using a combination of the fields. This is how photos are saved in Android but not in iOS.Ģ. Collector saving the photos to the iOS Photo Gallery. This is such a pain that we have opted to not collect photos using Collector.Ī few things that would be very helpful for us include:ġ. Once the photos have been extracted from the geodatabase they then have really complicated identifiers that we need to deal with in order to figure out what photo belongs to what site. It's a bit of a process to get the photos from the geodatabase so that we can save them in a folder on our computers, so that the photos can easily be uploaded to the provincial database.Ģ. Currently, the photos are stored in the geodatabase. We have found a few issues with the way Collector manages photos on iOS.ġ. At the end of the field season, we then upload the photos to a provincial database. Selecting a region changes the language and/or content on. Hence, wheel architecture is better suited for analytical queries. Using data wheels, each visitor’s data is organized into a single bag, so the query agent can evaluate each bag at once and move on to the next, allowing the wheel to finish a query in a single sweep. Consequently, when you have millions or billions of visitors, this will quickly becomes impractical. However, an analytical query is more open-ended and requires an answer to the question: "How many users fire how many events per session?" This requires a query across many records with the query agent repeating the expensive steps for all users. These are expensive steps for the database to use these external keys, but doing it for one person is still practical. It would also require a count of the number of events. Taro Adobe fire?” would require the query agent to look up one record on Visitor table, several on the Visit table, and more on the Hit and Event tables. For example, a query of “how many events did Mr. When a query is targeted for one entity, then the relational database can complete the query very quickly.
