Introduction:
The current version WMTS (OpenGIS® Web Map Tile Service) is 1.0.0. WMTS standard defines a number of operations which allow users to access slices map. WMTS may be the first to support RESTful access to OGC service standards.
· WMTS the principles and operations
If you know the bounds of a request, the slice number can be acquired according to the following algorithm:
// Calculate slice number range
. 6 = 1E-Epsilon [. 1] // does not affect the coordinate precision of a decimal value
tileMinCol = floor ((bBoxMinX - tileMatrixMinX) / tileSpanX + epsilon)
tileMaxCol = floor ((bBoxMaxX - tileMatrixMinX) / tileSpanX - epsilon)
tileMinRow = floor ((tileMatrixMaxY - bBoxMaxY) / tileSpanY + epsilon)
tileMaxRow = floor ((tileMatrixMaxY - bBoxMinY) / tileSpanY - epsilon)
// avoid out of range
if (tileMinCol < 0) tileMinCol = 0
if (tileMaxCol >= matrixWidth) tileMaxCol = matrixWidth-1
if (tileMinRow < 0) tileMinRow = 0
if (tileMaxRow >= matrixHeight) tileMaxRow = matrixHeight-1
Comprising the following three operations in a WMTS service:
1. GetCapabilities (acquired meta-information services)
2. GetTile (get sliced)
3. GetFeatureInfo (optional, getting features clickable)
BIGEMAP offline map server provides a way to map service WMTS
