Question

I'm trying to develop my own map service then display my generated images into ARCGIS map viewer ... Anyway my *.ashx service reads ARCGIS Tile URL looks like "http://services.arcgisonline.com/ArcGIS/rest/services/NGS_Topo_US_2D/MapServer/tile/1/1/2"

I want to transform the value of (Zoom/TileX/TileY) from the url above to Pixel or BoundingBox USING SRID 4326

BoundingBox values should not exceeds Max/Min value between (-180,-90) to (180,90).

I'm taking the Bbox then passe it to my Stored procedure witch intersects some SQL geography rows.

Any Ideas ?

Solution

You could look at BruTile's InvertedYAxis.TileToWorld

You will need to define a schema based on the information you find here: http://server.arcgisonline.com/ArcGIS/rest/services/NGS_Topo_US_2D/MapServer

Not sure if this is the easiest solution in your situation
