	The maximum amount of cells any given overlay or result type can have is {{max cells}} individual cells. For any given overlay, this includes the results of all timeframes of that overlay.		The maximum amount of cells any given overlay or result type can have is {{max cells}} individual cells. For any given overlay, this includes the results of all timeframes of that overlay.
	Per project it is possible to have an [[Overlay]] with result types where the maximum amount of grid cells is {{max cells\|group}} for the Overlay and the result types in total. You can have multiple Overlays + result type groups in your project. For example a [[Flooding Overlay]] with result types (max {{max cells\|group}} grid cells) and also a [[Heat Overlay]] with result types (also max {{max cells\|group}} grid cells). You can then for example add the [[Rainfall Overlay]] with result types (also max {{max cells\|group}} grid cells) etc.		Per project it is possible to have an [[Overlay]] with result types where the maximum amount of grid cells is {{max cells\|group}} for the Overlay and the result types in total.

	The maximum a mount of cells in a [[Project]] in total is {{max cells\|project}} individual cells. This includes all timeframes of all Grid Overlays, both active and inactive. Exceeding this amount will prevent the {{software}} from performing any further calculations of the [[Project]] until the amount of cells is reduced.

	When the calculation is completed, a final result value is stored in the cell. The value stored in the cell itself is a unitless number. The exact meaning of the number is dependent on the overlay which defines the calculation. A calculation for [[Traffic Noise Overlay\|traffic noise]] will present its result in decibels. A calculation for [[Subsidence Overlay\|subsidence]] in meters.		When the calculation is completed, a final result value is stored in the cell.

			There are also several generic attributes that can be used to guide the calculation of all Grid based overlays:
			{{overlay attributes\|suppresscategory=true\|allowselflinks=true\|
			{{:Iteration active (Grid Overlay)}}
			{{:Skip no data (Grid Overlay)}}
			{{:Gpu cluster index (Grid Overlay)}}
			}}

	A Grid Overlay is a calculated [[overlay]]. It uses a 2-dimensional grid for calculation, data storage and visualization. The calculation divides the entire [[project]] into a grid of equally sized square cells, with possible size per cell ranging from 0.~~25m²~~ up to 100m², depending on the size of the project area. This amounts to anywhere from thousands to millions of cells per [[Overlay \|overlay]].		A Grid Overlay is a calculated [[overlay]]. It uses a 2-dimensional grid for calculation, data storage and visualization. The calculation divides the entire [[project]] into a grid of equally sized square cells, with possible size per cell ranging from 0.01m² up to 100m², depending on the size of the project area. This amounts to anywhere from thousands to millions of cells per [[Overlay \|overlay]].

	For each cell, a calculation is performed, the specifics of which depend on the overlay being calculated. This can be as simple as displaying (possibly inherently) rasterized data, such as [[GeoTIFF Overlay]]s or the [[Heightmap Overlay\|heightmap]], or as complex as multi-step [[Rainfall Overlay\|rainfall calculations]].
