How can I use a script to extract the region name from a landmark?

[Life Camino]

I'm trying to convert landmark information to landmark name, region name, local coordinates and I can get the landmark name and convert from global coordinates to local coordinates.  But, I can't seem to figure out how to extract the region name from the landmark.  Any suggestions?

This should work correctly llRequestInventoryData() gives a vector to current region corner. You add 2, divide by 256 and you have the "grid coordinates" of the landmark which can be translated into the name through a HTTP Request:

 

key req;vector Absolute;default{    state_entry()    {        req= llRequestInventoryData(llGetInventoryName(INVENTORY_LANDMARK, 0));    }    dataserver(key id, string data)    {        if (id == req)        {            Absolute = llGetRegionCorner() + (vector)data;            vector grid = Absolute / 256.0;            req= llHTTPRequest("https://cap.secondlife.com/cap/0/b713fe80-283b-4585-af4d-a3b7d9a32492?"                                    + "var=name&grid_x=" + (string)llFloor(grid.x)                                     + "&grid_y=" + (string)llFloor(grid.y), [], "");        }    }    http_response(key id, integer status, list metadata, string body)    {        if (id == req)        {            if (status != 200)            {                llOwnerSay("Failure!");                return;            }            integer i = llSubStringIndex(body, "'");            body = llGetSubString(body, i + 1, -3);            llOwnerSay(llDumpList2String(, "/"));        }    }}

I don't know what the problem is, but I get nothing out of that script.  There is no output.

Just a minor typo.

The output line should say

llOwnerSay(body);

not

 llOwnerSay(llDumpList2String(, "/"));

It's a nice script. It works for me.

If you want to make it slightly fancier, you might want to add a changed event so that the script responds when you drop a new landmark in it.  Create a new global string variable, gOldLM, and then modify the script with

    state_entry()    {        gOldLM = llGetInventoryName(INVENTORY_LANDMARK,0);        req= llRequestInventoryData(gOldLM);    }    changed(integer change)    {        if (change & CHANGED_INVENTORY)        {            llRemoveInventory(gOldLM);            gOldLM = llGetInventoryName(INVENTORY_LANDMARK,0);            req= llRequestInventoryData(gOldLM);        }    }

Wow, they finally fixed this?

[Edit: Oh, you may not be able to see that jira. Well, the wiki page for the Map API says it, too: "Note: the capability for this service, b713fe80-283b-4585-af4d-a3b7d9a32492, is currently unavailable (BUG-4116). Maestro Linden 14:46, 22 January 2014 (PST)]

Yeah, it's been busted long enough that I forgot to keep looking.  I don't know when it came back up, but it's nice to have the API back again.  This is just the sort of thing it's good for.

[Life Camino]

Thanks, Rolig, that made all the difference.

Hi i know this isa old thread but is there away to construct the SURL from it please?

[VirtualKitten]

Also does not llGetRegionCorner() get the region corner your script is in not the one in the landmark? 

[Qie Niangao]

That's what's needed, to go with the offset values reported by llRequestInventoryData, to get the global coordinates of the landmarked region. Then the MapAPI request to get the region name corresponding to that location (converted to region global x & y coordinates).
