The spatial extents need to be defined when projecting and TIN or Grid, defining the extents of the output grid. The figure below shows the definition of spatial extents, used across all projection windows. The bounding box is defined by two points
Item
Description
1
This defines the extents from the source Map Window view extents.
This allows for manually typing in the coordinates.
5
This button makes the extents display in Latitude/Longitude.
6
This button makes the extents display in the Projection Coordinates.
7
The units of the coordinate (2000 meters in this case).
8
First X coordinate of the bounding box.
9
Second X coordinate of the bounding box.
10
First Y coordinate of the bounding box.
11
Second Y coordinate of the bounding box.
12
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 intersections themselves.
13
Selecting this will assure that the grid cell count in both the X and Y directions are integer numbers.
