Yes, you can develop and deploy an app built with any ArcGIS Runtime SDK for free. You will need to have a Developer Account (also free) and get your Lite license string from the License page. Note that if your app's needs Runtime capabilities that are not available at Lite level, then you will need to purchase appropriate Base or Standard licenses (Advanced level is not relevant to the iOS SDK). And of course there may be costs for using Location Services over the free monthly allowances. ... View more

Hi @Anonymous User  I need offline street and satellite elevation maps with routing for about a dozen countries. I have a few questions: 1. I understand that I need ArcGIS Publisher. But what version of ArcGIS Pro do I need? Pro Basic, Pro Standard, or Pro Advanced? The Publisher extension for ArcGIS Pro is only needed if you want to create an offline map package for anonymous use in our Field Apps such as Field Maps. Map and scene packages (MMPKs/MSPKs) combine multiple data sources and layer definitions in one ready-to-read map or scene definition, and ArcGIS Maps SDKs for Game Engines cannot yet read them. Instead, the Game Engine SDKs can read Scene Layer Packages (SLPKs) and Tile Packages (TPKs/TPKXs), each of which provides data for a single layer, which you can use to construct your ArcGIS Map. Those SLPKs, TPKs and TPKXs can be created in any version ArcGIS Pro (without a Publisher extension). You can use ArcGIS Pro to create a Scene Layer Package of 3D Object data or Integrated Mesh data, or a Tile Package of basemap data or LERC-encoded elevation data. 2. After I create the offline maps that are accessible through Unity, do individual users need ArcGIS subscriptions or are those offline maps covered by my subscription? They do not, no. Just distribute and use the SLPK/TPK/TPKX files and consume them in your app. As always, make sure you're honoring the data usage rights for the data you're including in your offline packages. 3. Is there any documentation or examples of how I access these offline maps from within Unity? Yes... https://developers.arcgis.com/unity/maps/tutorials/display-a-map-api/ Just reference the locally stored file instead of the service when creating each Layer. See these links for more info: https://developers.arcgis.com/unreal-engine/layers/#set-a-basemap https://developers.arcgis.com/unreal-engine/maps/elevation/#set-elevation 4. Does it matter whether maps are online or offline for routing?  At this time, routing in the ArcGIS Maps SDKs for Game Engines requires a connection to a routing service. However, the map layers themselves on which you overlay the route results can be any combination of online or offline layers. The two things (routing and layers) are distinct. 5. Do individual users need ArcGIS subscriptions to do routing, or can I use my API key? They do not need ArcGIS Subscriptions, no. You can use your API Key to deliver solutions that do routing (you get 20,000 routes for free per month). Depending on the nature of the app, and the target users, some developers choose to require/let their users use their ArcGIS Subscription, and you can certainly do that, but it's not a consumer-oriented approach. If your target users are not already ArcGIS subscribers, then an API Key is the appropriate approach. Hope that helps! ... View more

For performance reasons, where objects have a strong dependent relationship (e.g. a FeatureLayer is dependent on (or "owns") a FeatureTable), that is limited to a single "owner" at a time. It looks like you do not need this line:   arSceneView.sceneView.scene.tables.addAll(featureTables)   You are taking the feature tables that you have already created feature layers for (i.e. each FeatureTable is already "owned" by a FeatureLayer) and trying to add them to the Scene's tables collection. This will try to set the Scene as the table's owner, but the layer is already the owner. The scene's tables property is for standalone tables that are not used by a layer (perhaps they're related to features and/or don't have geometry). ... View more

It's not planned, no. Most people will use Runtime directly against the service. In your case do you need to parse out just the compressed geometry, or would it be helpful to be able to parse the entire route result into an AGSRouteResult? ... View more

Hi @AndriyFedin  There might be two problems. Runtime only supports LERC tiles for elevation, and not visualization. You would need to publish a service that supports one of the formats listed here. Sorry we didn't spot that sooner when you replied in the original post! Note that Runtime cannot reproject tiled images, so if you tried to display this service (WGS84) in a Web Mercator map, it would not display. That's something you can work around by suitably authoring/constructing the map. However, even if that's the case, the format can't be LERC. Hope that helps! ... View more

I don't have a huge amount of experience here, but the resolutions look really small. Have a look at this tiling scheme: https://services.arcgisonline.com/arcgis/rest/services/Canvas/World_Dark_Gray_Base/MapServer The resolution (real world meters per pixel) you have for your global scale (1:5,910,000,000) is about the same as 1:4,500 (level 17) in the standard web mercator tiling scheme. It's about 100,000 times off from the resolution of that scale's tiles in the standard scheme. I'd have a look at the parameters you're using when exporting from Pro. ... View more

FYI, I built this from the Terraformer code. Hope that works for you! extension AGSGeometry { static func decodeCompressedGeometry(_ compressedString: String, spatialReference sr: AGSSpatialReference) -> AGSPolyline? { // Break the string up into signed parts. // The first part is a coefficient. // Subsequent pairs of parts make up the remaining coordinates. let pattern = #"((\+|\-)[^\+\-]+)"# guard let regex = try? NSRegularExpression(pattern: pattern, options: []) else { return nil } let range = NSRange(compressedString.startIndex ..< compressedString.endIndex, in: compressedString) let components = regex.matches(in: compressedString, range: range).compactMap { Range($0.range(at: 0), in: compressedString) }.compactMap { range -> Double? in let val = Int(compressedString[range], radix: 32) ?? 0 return Double(val) } guard let coefficient = components.first, (components.count - 1) % 2 == 0 else { preconditionFailure("Invalid compressed geometry. Needs coefficient plus even number of subsequent parts!") } var coordinatePairs = [(Double,Double)]() for i in stride(from: 1, through: components.count - 1, by: 2) { let pair = (components[i],components[i+1]) coordinatePairs.append(pair) } var xDiffPrev = 0.0 var yDiffPrev = 0.0 var x = 0.0 var y = 0.0 let builder = coordinatePairs.reduce(AGSPolylineBuilder(spatialReference: sr)) { builder, pair in x = pair.0 + xDiffPrev xDiffPrev = x y = pair.1 + yDiffPrev yDiffPrev = y let newPoint = AGSPoint(x: x / coefficient, y: y / coefficient, spatialReference: sr) builder.add(newPoint) return builder } return builder.toGeometry() } }   ...

So, I have some information, but it means you'll have to write some code yourself 🙂 Take a look at this code form Terraformer, which shows how to decompress this geometry using JavaScript. You'd have to translate that to Swift of course but it should show how to do it.   function decompressGeometry(str) { var xDiffPrev = 0; var yDiffPrev = 0; var points = []; var x, y; var strings; var coefficient; // Split the string into an array on the + and - characters strings = str.match(/((\+|\-)[^\+\-]+)/g); // The first value is the coefficient in base 32 coefficient = parseInt(strings[0], 32); for (var j = 1; j < strings.length; j += 2) { // j is the offset for the x value // Convert the value from base 32 and add the previous x value x = (parseInt(strings[j], 32) + xDiffPrev); xDiffPrev = x; // j+1 is the offset for the y value // Convert the value from base 32 and add the previous y value y = (parseInt(strings[j + 1], 32) + yDiffPrev); yDiffPrev = y; points.push([x / coefficient, y / coefficient]); } return points; }   This pull request also includes a test that could help. If you come up with a Swift version of this, please share! I won't have time to try until next week, but it should be achievable. For reference, here is some really old documentation that explains the process. ... View more

ArcGIS Runtime SDK for iOS cannot open file geodatabases (you would need Local Server for that, which is only available on .NET, Java, and Qt when deploying to Windows or Linux). I would suggest using ArcGIS Pro to create a Mobile Geodatabase, which can be opened using the AGSGeodatabase class. You could also conceivably use a GeoPackage but a) that is more limited than a Mobile Geodatabase in terms of the schema it supports (attachments, related records, domains, etc.) and b) it would require a Standard Runtime license. ...
