The STATE-WIDE OLD GROWTH SURVEY GRID and STATE-WIDE OLD GROWTH SURVEY GRID CENTROIDS dataset were developed to assist the verification of the presence or absence of old growth forest in Victoria. The STATE-WIDE OLD GROWTH SURVEY GRID dataset is a 1-hectare square grid which has been created in ArcGIS pro 2.3. STATE-WIDE OLD GROWTH SURVEY GRID CENTROID is the centre of each 1-hectare square grid cell. This is polygon layer consisting of 100mX100m squares covering the extent of Victoria. Within each square is a centroid that is used as a survey point for undertaking tree assessments. The centroids are located within a square that has a bounding box with coordinates that are divisible by 100. So a centroid with coordinates 2,616,250m 2,400,050 is within a square with left X = 2,616,200 and right X =2,616,300, bottom Y = 2,400,000 and top y = 2,400,100.

The STATE-WIDE OLD GROWTH SURVEY GRID dataset is a 1-hectare square grid which has been created in ArcGIS pro 2.3. STATE-WIDE OLD GROWTH SURVEY GRID CENTROID is the centre of each 1-hectare grid cell. The extent of this data is aligned with the Modelled Old Growth (MOG) dataset and 400m buffered.
