It's all done using the 'relevant' column in Connect.  Here's a good example of showing an 'issue comments' question with visibility dependent on either of 2 questions.  https://community.esri.com/t5/arcgis-survey123-questions/survey123-relevant-field-based-on-value-from-more/td-p/841259 If your questions have multiple answers e.g. arable and pasture - then use the 'selected()' syntax https://community.esri.com/t5/arcgis-survey123-questions/quot-relevant-quot-field-syntax-for-multiple/td-p/775051     ...

You wont be able to edit a public dataset that you don't own.  You may be able to create a Hosted Feature Layer view with a SQL filter/selection but I've not done that on content I don't own. Maybe the simplest solution would be adding a filter to the layer in the Web map layer properties. https://doc.arcgis.com/en/arcgis-online/create-maps/apply-filters-mv.htm https://doc.arcgis.com/en/arcgis-online/reference/apply-filters.htm https://doc.arcgis.com/en/arcgis-online/manage-data/create-hosted-views.htm   ...

What's the RAM usage like and number of services?  The ArcSOC processes associated to them can be quite hungry. ... View more

Depends on the shape of your polygons.  Would make sense if there's multiple regions of non continguous overlaps. You can probably just clean up with a Dissolve https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/dissolve.htm against a common attribute (FID_MD ?) and keep in mind the single/multipart options. Or Tabulate Intersection may be a better tool to use https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/tabulate-intersection.htm But not entirely sure what your end goal is.  Might be best to offer up the problem in its entirety (pictures are always helpful) and see if a better way can be found - as the multiple intersections might be quite complicated, error-prone and more difficult to reproduce if you have any later adjustments to your input data. ...

I think you need to do a bit of troubleshooting.  Look at the image format and ensure it was added from the insert ribbon, not copy pasted etc. Try a different image, save as a different format, look at image size, resolution etc.  That will give you more to go on. ... View more

I'd open it in notepad and check if anything is different in the formatting. ... View more

have you got another Map Frame?  Could maybe be an extent indicator linked to that other frame. https://pro.arcgis.com/en/pro-app/latest/help/layouts/extent-indicators.htm ... View more

have you set the parameter in the toolbox to 'output' If that doesn't work then try adding a derived parameter as output as per: https://community.esri.com/t5/arcgis-pro-questions/how-to-display-feature-layer-from-python-toolbox/td-p/1249618 ... View more

Ah yeh certainly needs extensive debugging and putting into Arcade syntax.  More to give an idea of utilising the Helmert transform. ... View more

You might be stuck with coding-in the Helmert transformation 😬 Chat GPT so needs tested, and has probably dreamt up half of the Function and Constant names.  But maybe a starter for 10.   // Input BNG coordinates (replace with actual values) var x_bng = 532256; // Easting (X) var y_bng = 180749; // Northing (Y) // Constants for conversion (simplified Helmert transformation parameters) var a = 6377563.396; // Semi-major axis of Airy 1830 ellipsoid var b = 6356256.909; // Semi-minor axis var e2 = (a^2 - b^2) / a^2; // Eccentricity squared // Origin of BNG grid var n0 = -100000; // Northing of true origin var e0 = 400000; // Easting of true origin var phi0 = 49 * (PI / 180); // Latitude of true origin (degrees to radians) var lambda0 = -2 * (PI / 180); // Longitude of true origin (degrees to radians) var f0 = 0.9996012717; // Scale factor on the central meridian // Calculate latitude and longitude in radians var n = (a - b) / (a + b); var n2 = n * n; var n3 = n * n2; var phi = phi0; var m = 0; var max_iter = 1000; // Iteratively calculate latitude (phi) from northing (y_bng) do { var phi_prev = phi; m = b * f0 * ( (1 + n + (5/4)*n2 + (5/4)*n3) * (phi - phi0) - (3*n + 3*n2 + (21/8)*n3) * sin(phi - phi0) * cos(phi + phi0) + ((15/8)*n2 + (15/8)*n3) * sin(2*(phi - phi0)) * cos(2*(phi + phi0)) - (35/24)*n3 * sin(3*(phi - phi0)) * cos(3*(phi + phi0)) ); phi = (y_bng - n0 - m) / (a * f0) + phi; } while (abs(phi - phi_prev) > 0.00001 && --max_iter > 0); // Calculate longitude var sin_phi = sin(phi); var cos_phi = cos(phi); var tan_phi = tan(phi); var nu = a * f0 / sqrt(1 - e2 * sin_phi^2); var rho = a * f0 * (1 - e2) / pow(1 - e2 * sin_phi^2, 3/2); var eta2 = nu / rho - 1; var x_diff = x_bng - e0; var lat = phi - (tan_phi / (2 * rho * nu)) * (x_diff^2 - (5 + 3*tan_phi^2 + eta2 - 9*eta2*tan_phi^2) * x_diff^4 / 24); var lon = lambda0 + (1 / (cos_phi * nu)) * x_diff - (1 / (6 * cos_phi * nu^3)) * (1 + 2*tan_phi^2 + eta2) * x_diff^3; // Convert latitude and longitude from radians to degrees var latitude = lat * (180 / PI); var longitude = lon * (180 / PI); // Output the WGS84 coordinates return "Lat: " + latitude + ", Lon: " + longitude;     ...
