HEC-MetVue provides support to writing projected TINs to files in virtually any coordinate system with any grid size using an I/O provider plugin. One provider that supports a wide range of choices is the provider that writes ESRI grid files.

Description

1 

This gives a list of the coordinate systems that can be used by the specified I/O provider that are currently defined within HEC-MetVue. By default HEC-MetVue provides coordinate system definitions for Lon-Lat, HRAP, and SHG coordinate systems. Other user defined coordinate systems that are supported by the currently selected I/O provider also appear in this list.

Use this button to add more coordinate system definitions or to modify or copy an existing definition. Refer to the Coordinate System Editor for how to define additional coordinate systems.

 3

This defines the extents to use form the target grid for the output gridded TINs.

 4

This specifies the size of the grid cell in units defined by the coordinate system projection. In the example above, the coordinate system is SHG with every coordinate increment being 2000 meters. Therefore the size of the grid cell is 1 which means a grid cell is 2000m in each direction.

 5

Selecting this will cause the projected grid to contain a half cell offset so that the source grid sampling is done at the centers of the defined grid cells instead of the grid cell intersections themselves.

 6

Selecting this will assure that the grid cell count in both the X and Y directions are integer numbers.

 7

This is the location to enter the file pattern for storing the projected TIN files. A file pattern is required so that each TIN written can be written to a different file.

 8

This field is a sample of what the filenames used for the projected TINs will resemble based on the given pattern. It is non editable.

 9

This field is used to provide feedback about the target projected grid that will be created so that the created grid will have the expected number of grid cells defined.
