You can search the catalogue by location, using a map search
In the left-hand search panel, click on the "Spatial search" option - a map will appear
Click on the draw tool. This will allow you to draw an area on the map
When you draw an area, the search results will change to show data resources in that area.
"Intersects" and "Within"
When searching using the map, there are two search options which you can change using the toggle
Intersects finds data resources that are entirely or partially inside the area you are searching
Within only finds data resources that are entirely inside the search area
In the example below, an Intersects search would return datasets 1 2 and 3 because they all overlap the search area . A Within search would return only dataset 2 because it is the only one completely inside the search area.
