I just wanted to supplement my question with some code that I'm trying to use to help explain the trouble I'm having.
AGSSpatialReference *sr = [[AGSSpatialReference alloc] initWithWKID:102017 WKT:@"PROJCS[\"North_Pole_Lambert_Azimuthal_Equal_Area\",GEOGCS[\"GCS_WGS_1984\",DATUM[\"D_WGS_1984\",SPHEROID[\"WGS_1984\",6378137,298.257223563]],PRIMEM[\"Greenwich\",0],UNIT[\"Degree\",0.017453292519943295]],PROJECTION[\"Lambert_Azimuthal_Equal_Area\"],PARAMETER[\"False_Easting\",0],PARAMETER[\"False_Northing\",0],PARAMETER[\"Central_Meridian\",-95],PARAMETER[\"Latitude_Of_Origin\",40],UNIT[\"Kilometer\",1000]]"];
AGSEnvelope *env = [AGSEnvelope envelopeWithXmin:-2500
ymin:-1500
xmax:2500
ymax:1500
spatialReference:sr];
AGSGraphicsLayer* glayer = [AGSGraphicsLayer graphicsLayer];
glayer.initialEnvelope = env;
UIView<AGSLayerView>* lyrView = [self.mapView addMapLayer:glayer withName:@"Graphics Layer"];
AGSMutablePolyline *poly = [[AGSMutablePolyline alloc] initWithSpatialReference:sr];
[poly addPathToPolyline];
// points add to the polyline
AGSSymbol* s = [[AGSSimpleLineSymbol alloc] initWithColor:[UIColor redColor] width:10.0f];
AGSGraphic* g = [[AGSGraphic alloc] initWithGeometry:poly symbol:s attributes:nil infoTemplateDelegate:nil];
[glayer addGraphic:g];
[glayer dataChanged];
It's unclear to me what units the AGSEnvelope should be in... kilometers?It was from these pages that I got information about the WKID/WKT for this projection: http://wikis.esri.com/wiki/display/mobileSDK/mobilepcs, and http://spatialreference.org/ref/esri/102017/esriwkt/.However, the AGSGeometry.h API page it makes me unsure if this project is actually support by the iOS SDK.Any help would be greatly appreciated!Peter
