Provenance information | The Inventory_of_Irish_Coastal_Lagoons_polygons.shp dataset was based on the lagoons identified in the Inventory of Coastal Lagoons 2007. Included in the inventory were sketch maps for each lagoon. However, due the scale and lack of background mapping these sketch maps could only be used as a reference tool in the creation of this spatial dataset. The OSi 1:5000 vector dataset was used as the basis for the creation of the Inventory_of_Irish_Coastal_Lagoons_polygons.shp dataset. The polylines from the OSi 1:5000 dataset, which corresponded to the extent of the lagoons were copied into a new lagoon polyline dataset. These polylines were then converted into a polygon dataset. In cases where the OSi 1:5000 vector dataset did not contain any spatial data for lagoons identified in the inventory, the OSi 2005 orthophotographs (1:40000) were used as the base layer to manually digitise the boundary of these lagoons. It should be noted that expert knowledge was used to correct instances where what was indicated on the OSi 1:5000 dataset did not match what was apparent on the ground from the orthophotographs. This dataset has been created using ArcMap 10. The source coordinate reference system is the Irish National Grid. |
