Hi fellow Survey123 users I have a significant issue on my laptop - My Survey123 Windows client refuses to see my internet access: I have uninstalled and reinstalled with no resolution to the problem. When I install it on a different computer it works fine. I am also unable to get to the Settings for some reason - the whole landing page is just the logo and the error message. The strangest part of this is that the Survey123 Connect application works perfectly with no issues. Hope someone has stumbled across this and have an answer for me. ... View more

Hi I was working on ArcGIS Pro 2.1.1 when an error occurred and caused my laptop to restart. Once it restarted and I opened ArcGIS Pro it wanted me to provide login / licensing details again. Every time I type in my username / password I get the following error : Invalid URL I have checked the URL and it is correct. I tried the normal www.arcgis.com URL as well as our Organisational URL https://esriza-ps.maps.arcgis.com  to no avail. I know it is hitting the correct URL because if I type an incorrect password I do get an error indicating that my username / password is incorrect. I have removed and reinstalled ArcGIS Pro to no avail. I also ran Fiddler and no significant issues are detected. Any ideas? ... View more

On Friday I tried to scan a Code39 barcode with Survey123 and didnt have any success even though I had the Code39 option checked. I used another Barcode Scanning app and was able to scan successfully. Does anyone know if Survey123 has limitations in terms of scanning 1D barcodes? Perhaps the barcode has to be of a minimum size? ... View more

(view in My Videos) This blog post provides a solution for:      Capturing multiple locations per survey      Calculating straight-line distances between a base location point in the survey and other repeating locations         captured Consider the scenario where your survey must assist in the administration of new liquor licence applications and the law stipulates: New liquor premises must be located at least five hundred meters (500m) away from schools, places of worship, recreation facilities, rehabilitation or retreat centers, residential areas and public institutions. For this requirement Survey123 can be a valuable tool and in this blog post I will show you how you can enable this functionality in a Survey123 form: Step 1: Create a new survey with Survey123 Connect Step 2: Create a geopoint field in the main survey which will be used to capture the location of the new licence premises (the base point or new_licence_location field in the survey below) Step 3: Create a repeat section to capture the occurrences of nearby schools, places of worship etc. Each with a premise type and a geopoint (the nearby_location field in the survey below) Your survey design should look similar to this: Step 4: Now, split both the coordinates sets into their x,y pairs and convert them to radians: Do the same for the nearby_location geopoint field: Step 5: Use the X, Y (lat,long) pairs to perform the distance calculation (in meters) with the Haversine formula: acos(sin(${gps_lat_end})*sin(${gps_lat}) + cos(${gps_lat_end})*cos(${gps_lat})*cos(${gps_long}-${gps_long_end}) ) * 6371000 After making some cosmetic enhancements (and adding the 500m stipulation) your survey should look like this: The user can add multiple locations (Nearby Premises) at will in the repeat section and each will have it's own distance calculation to the base point (New Licence Location). The Survey123 Excel Design file is attached to this blog.  Feel free to use and adapt as you require! ... View more
