I’m trying to write a query that will select features from a file geodatabase string field containing specific characters. The format of the string is “12_XYZ_XYZ_WXYZ_A_C01C_+##” The specific part I am trying to search for is the first letter C, which describes what that particular feature is. It can also be A, B, or D. I need a way to select all the features that contain either “A”, “B”, and so on. I’ve tried several different queries using *, ?, and % as wildcards but none have worked so far. Any assistance would be greatly appreciated.

Hi Cody, Here are the properties for the imagery from ArcCatalog: There was also a text file with the imagery containing the following information: I also noticed in the Data Frame Properties window under the Coordinate System tab that in the projection for all of my vector data is in a Lambert_Conformal_Conic projection, and that the projection for the raster data is set to Transver_Mercator. Could this be causing the problem? I did not order the imagery personally, and I don't know if the person who order it specified what projection we needed. Thanks!

Thanks for your reply, Dan. Some of the terminology was a little above my experience level (please bear with me, I’m somewhat new to working with imagery), but I think I got the gist of what you were saying. I tried playing around with projecting the raster in a new data frame, and I’m wondering now if projecting the raster is really want I need to be doing here. Let me explain the exact problem I’m working on. We recently purchased imagery for our service area to be loaded into ArcGIS Online for use in Collector. Before we can do that, we need the imagery to line up with parcels, roads, etc. I figured the easiest way to do that would be to just reproject the raster, but that is more complex that I originally thought. Below is a screen shot of the parcels in the area I am working (orange) on top of Esri’s World Imagery basemap: Here is an image of the same parcels layer, this time on top of the original raster. The imagery does not align with the parcels, I assume because they are in different projections: Lastly, this is an image of the parcels layer on top of the raster once it has been projected into the State Plane: Looks pretty much identical to the original raster. I noticed that it did shift a little bit, but not nearly enough to be useful. Is it possible that I need to do something else besides projecting the raster? What’s the best route for getting the imagery to line up with the parcels layer? Thanks for your help!

I’m trying to use the Project Raster (Data Management) tool to reproject a .tif or .IMD file from NAD_1983_UTM_Zone_13_N into NAD_1983_StatePlane_Colorado_South_FIPS_0503_Feet. Every time I run the tool the output raster looks just like the UTM projection. The only thing that changes is the layer properties for the output raster claims it’s in the State Plane projection, yet it is identical to the UTM projection. Am I missing a step in the process here?

Hi Kelly, I’ve figured out how to link a meter photo to a feature in ArcGIS Online: -I upload photos into a folder in my content -I share those photos publically, enabling me to get the URL for each photo -The URLs for each photo are saved as an attribute (Photo_URL) in the water meter’s layer -In Collector, the pop-up for the meter’s layer is set to display the picture via the "Photo_URL" attribute -I can overwrite the feature layer without losing the connection to the photo. From what I can tell, sharing a photo publically is the only way to get a URL for that photo. I need a URL in order to link each photo to a feature. Is there a way to get the URL for a photo saved in My Content without sharing it publically? If not, what are the risks involved with sharing a photo publically? The photos may contain customer information that needs to stay private. What are Esri’s workflows and best practices for this situation? Thanks, -J.

Hi Kelly, Thanks for your response. I am overwriting the feature service when I update the layer. In the updates only attributes are being changed. Thanks, -J.

I have a point feature layer in AGOL that represents water meters and will be updated with new information monthly. I also need to take pictures of each meter, which are stored as attachments in AGOL for reference. The problem I’m running into is that whenever I update the meters layer each month, I will lose any attachments when the layer is updated. Is there a way that I can update a layer in AGOL without losing the attachments? My current solution for this is to have two copies of the same layer in AGOL: one for updates, and one for photo attachments. Does anyone have a better solution?
