	The project data is rasterized with cells of the specified size. The more cells that need to be calculated, the more resources (and in the end: time) it will take to complete the calculation. Depending on the use-case and the calculation being performed, it may be desirable to change the grid size used for the grid overlays.

	The visualization of the grid overlay in the [[3D Visualization]] can be changed by providing a legend for the grid overlay. The legend of a grid overlay consists of a list of values with related captions and colors. When that specific value is output by a grid cell, that grid cell is colored in the defined color. If the value lies between two defined values, the color will lie proportionally between the colors related to the defined values.

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)}}
			}}
