![]() With each increasing resolution value, the area of the polygons will be one seventh the size. Specifies the H3 resolution of the hexagons. The map may be using different display units Values and in the active map's coordinate system. Manually entered coordinates-The coordinates must be numeric.Reset Extent -The extent will be reset to the default value.Union of Inputs -The extent will be based on the maximum or combined extent of all inputs.If no inputs overlap, a null extent with all zeros will result. Intersection of Inputs -The extent will be based on the minimum or intersecting extent of all inputs.Browse -The extent will be based on an existing dataset.This option is only available when there is an active map with layers. Use the drop-down list to choose an available layer or use the Extent of data in all layers option to get the combined extent of all active map layers, excluding the basemap. Extent of a Layer -The extent will be based on an active map layer.This option is only available when there is an active map. Current Display Extent -The extent will be based on the active map or scene.This can be the currently visible area, the extent of a dataset, or manually entered values. The extent that the tessellation will cover. To determine the area of a shape based on the length of a side, use one of the following formulas to calculate the value of the Size parameter: The tool generates shapes by areal units. To generate a grid that excludes tessellation features that do not intersect features in another dataset, use the Select Layer By Location tool to select output polygons that contain the source features, and use the Copy Features tool to make a permanent copy of the selected output features to a new feature class. ![]() For example, select all features in column A with GRID_ID like 'A-%', or select all features in row 1 with GRID_ID like '%-1'. This allows for easy selection of rows and columns by query using the Select Layer By Attribute tool. The format for the IDs is A-1, A-2, B-1, B-2, and so on. ![]() When the Shape Type parameter value is H3 hexagon, the GRID_ID field values will be a unique hierarchical index for each cell.įor all other Shape Type parameter values, the GRID_ID field will be a unique ID for each feature. The GRID_ID field will be added to the output. This occurs because the edges of the tessellated grid will not always be straight lines, and gaps would be present if the grid was limited by the input extent. To ensure that the entire input extent is covered by the tessellated grid, the output features purposely extend beyond the input extent.
