OSi Discovery Series Vector Tiles
-
Discovery Vector and Discovery Contours VisualisedThis document shows an example of a Discovery Vector tile and an example of a Discovery Contour tile. It also shows an image where these tiles have been merged using ArcGIS. Lastly, it shows the merged tiles overlaid on Discovery Raster mapping in ArcGIS. Discovery Raster mapping is available via MapGenie.
Both sets of data are in vector format and in the Irish Grid projection coordinate system. Resolution: Contours: vertical interval of 10m.
Please complete and submit the application form OSi Mapping Request Form: Discovery Vector and Contour Vector Data to request up to five tiles. See bottom of this page to find out about requesting a single shapefile of Discovery contour data for the Republic of Ireland.
Discovery Tiles Index
Click on the Discovery Index above to find the tile (s) you need. Each of the 251 tiles which cover the country are represented on the squares above. Tiles for your area of interest are available to obtain by request by completing the online application form above.
For each square shown above two tiles can be supplied, e.g. 1838_C for the contour lines layer and 1838_D for the Discovery vector layer. Don't forget to ask for both!
Here's an enlarged extract from the index which shows you how to find the right tile number:
Read the Eastings along the bottom of the grid, followed by the Northings up the side to get your tile number.
Read the number on the vertical line at the left hand side of the square you need. Next, read the number on the horizontal line below the square you need. In this example above the square coloured blue is tile number 2408. In other words the Easting number is 24 and the Northing number is 08.
