GeoMedia Grid layers

by Technical Evangelist Wednesday (11 Views)

Question

How are grid layers created in Grid Analysis?

Answer

There are five ways to create new grid layers in Grid Analysis:

 

  1. Grid layers can be imported using the Import command.

          * Non-square cells are not supported by Grid Analysis.

 

  1. A vector feature class can be rasterized to create a grid layer using the Rasterize Features command.
  2. A new, blank (univalued) grid layer can be created using the New command.
  3. A grid layer can be duplicated in the same Study Area, using the Duplicate command, or copied (and reprojected, if necessary) to a different Study Area, using the Reproject command.  Alternately, a Study Area and all the grid layers belonging to it can be duplicated using the Duplicate command.
  4. A grid layer is created every time an analysis command is executed. This is probably the most common means of adding grid layers to a Study Area.
  5. Grid layers at the top lefthand corner of the Study Area will have an origin of 0,0. Other positions will have row/column origins relative to this. Rows progress downward and columns progress left to right.
