A grid sector is a square with 100 sims length and 100 sims wide. In kilometers, that is about 25.6/25.6 km. It looks like the Linden officials use something similar for the grid map. When you scale the map to lowest resolution, image does not form in the same moment for all the map. Image is formed for different parts of the map, parts that have shape of a square. This means that, at lowest resolution, grid map texture is saved in squares of about 100/100 sims.

Grid Sectors

A Grid Sector is an unofficial name given for a part of the grid (or world map). The name was invented by the Geography Of Second Life group while editing List Of Microcontinents And Sim Clusters. The system proved to be very effective for map orientation.

Size

K10 sector and most of mainland continents

A Grid Sector is a square with 100 sims length and 100 sims wide. In kilometers, that is about 25.6/25.6 km. It looks like the Linden officials use something similar for the grid map. When you scale the map to lowest resolution, image does not form in the same moment for all the map. Image is formed for different parts of the map, parts that have shape of a square. This means that, at lowest resolution, grid map texture is saved in squares of about 100/100 sims.

An even smaller division is the Microsector.

Naming and coordinates

The only way to define the position of a structure on the map is by using Coordinates. The coordinates are similar to those used by Gridsurvey[1], in format longitude (min-max) /latitude (min-max) for a region of map and longitude/latitude for a single sim. The oldest sim, Da Boom, in Sansara, has coordinates 1000/1000.

Grid Sector are named with letters from left (West) to right (East) and with numbers from down (South) to up (North), exactly like the squares in a chess board. Theoretically, they start with grid sector A1 and end with T20. In practice, many grid sectors are in fact void sectors.

Using grid sectors

F11 sector contains many islands and structures

Unlike coordinates, it is much simpler to manage and understand a grid sector's position. It is a much easier way to find the position of a Continent, Subcontinent, Microcontinent, Sim Cluster, Sim Group or Isolated Sim using a Grid Sector.

Useful scripts

The following script can tell you your Coordinates, sim name and Grid Sector. put it into a HUD prim or an item you wear and when you touch it, you will know where you are:

<lsl> //Created by Ana Imfinity list sectors = [ 

   "zero", "A", "B", "C", "D", "E",
   "F", "G", "H", "I", "J", "K",
   "L", "M", "N", "O", "P", "Q",
   "R", "S", "T", "U", "V", "W"];

default { 

   touch_start(integer num_detected)
   {
       vector regionCorner = llGetRegionCorner();

// 0x100 = 2^8 (2 power 8) = 256 

       integer grid_x = (integer)(regionCorner.x/0x100);
       integer grid_y = (integer)(regionCorner.y/0x100);

       integer column_number = (integer)(grid_x/100);
       string  column        = llList2String(sectors, column_number);
       integer row           = (integer)(grid_y/100);

       string sim = llGetRegionName();

       string output = "Current grid position: ("
                   + (string)grid_x + ", " + (string)grid_y
                   + ")\n\tGrid sector:\t   " + column + (string)row
                   + "\n\tSim name:\t\t '" + sim + "'";

       llOwnerSay(output);
   }

}

// Example output: // // Current grid position: (1023, 1007) // Grid sector: J10 // Sim name: 'Help Island Public' </lsl>
