I have a point shapefile in QGIS (3.30.2) containing more than 2000 points. I selected about 150 of these points based on a special criteria.
I need to create a separate shapefile with only these 200 points. I usually select the desired rows in attribute table manually and use 'Export > Save selected features as >'. Considering the high number of points (150), is there an easier way to select these rows?
Update: I don't think it is possible to use 'select by expression', because they do not have a value greater or less than a specific amount. They are not categorized in any way.
Each point has a number associated to it and I selected them based on their photo, which had a particular characteristic, and the photo was inside a link, in one of the fields of the attribute table.
So, the only way, in my opinion, is to write the number of all these 150 point in an expression and use 'OR' or 'AND' to select them all. Is that correct? Which expression would use less time?
