Sir

Using ESRI map and checkmate SDK, how can i get an address when i have x and y coordinates, same as in Activity and Trips report. Advise on appropriate SDK code to use.


Thank you

Hi Tonny,

A quick look at the SDK help file (checkmatesdk.chm) which is included in the SDK archive will show that for a reverse address lookup you require the following function:

IAddressFromCoordinate

Hello Mauriciomuniz

I found the IAddressFromCoordinate command in help file, but do not know how to use it. IAddressFromCoordinate.GetAddresses seems to be my solution, but I cannot initialize the command with my x,y coordinates. Send a sample code, assuming I have x, y coordinates in SimpleCordinate SDK Geotab format.

Thank you

Tonny

Try something like below:
GetAddresses(new PointF[] { new PointF((float)simpleCoordinate.X, (float)simpleCoordinate.Y) });

Hello

Before doing addr.GetAddresses(new PointF[] { new PointF((float)simpleCoordinate.X, (float)simpleCoordinate.Y) });, I need to initialize an IAddressFromCoordinate variable as follows :
IAddressFromCoordinate addr = something

I do not know what code to replace with "something". Once this is initialized, i think i will be able to proceed. The help file does not explain how to initialize/configure the command IAddressFromCoordinate.

Following the examples in the SDK, I was able to initialize a DataStore, but I do not know what else is needed. As such, so far I used only the DataStore command.

Please advise

Tonny

IAddressFromCoordinate addressGeocoder = mapEngineFactory.GeocoderFactory.GetReverseGeocoder(GeocoderType.VirtualEarth);

Hello

This time, it seems that we either need to initialize mapEngineFactory, or GeocoderFactory, and still, I do not know how to initialize them. It seems that only GeocoderFactory needs to be initialized.
I get the following message
System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."

Thank you

This is how it works:
ICollection GetAddresses(DataStore dataStore, IWebProxy webProxy, IEnumerable simpleCoordinates)
{
ICollection addresses = new List();
using (MapEngineFactory mapEngineFactory = new MapEngineFactory(dataStore, webProxy))
{
mapEngineFactory.Load(new MapView("world", new RectangleF(-180, 90, 180, -90)));
IAddressFromCoordinate addressGeocoder = mapEngineFactory.GeocoderFactory.GetReverseGeocoder(GeocoderType.VirtualEarth);
foreach (SimpleCoordinate simpleCoordinate in simpleCoordinates)
{
IGeocodeResult[] geocodeResults = addressGeocoder.GetAddresses(new PointF[] { new PointF((float)simpleCoordinate.X, (float)simpleCoordinate.Y) });
IGeocodeResult result = geocodeResults[0];
if (result.Exception != null)
{
addresses.Add("");
}
else
{
addresses.Add(result.StreetAddress);
}
}
}
return addresses;
}

Great, it works. Thank you.

Once I loaded the mapEngineFactory with mapEngineFactory.Load, I got the right results.

Once again, thank you very much.

I read from other topics that version 5.5 is on its way. How can we download and test it?
