Simple server test for tile map (without Azure)

• This test tried to develop a minimum tilemap function. This is a simple tilemap and does not fully cover ESRI's tilemap function. Thinking the tilemap function used in ArcGIS online, we have prepared a minimum function as below.

  • Data in tilemaps at any zoomlevel are always 32 by 32 (width and height).
  • At zoom levels until 5, row and column are always 0.
  • At each zoom level, larger than zoom level 5, data in tilemaps at any row/column are the same. (if exist, it is all 1.)

• Try to use tile map from: https"//(root dir name)/TM/ne-test/(zoom level)/(row)/(column)/(width)/(height)

  • note1: "ne-test" is a name of dataset.
  • note2: Both width and height should be 32.
