Purpose

 

This tool is used to cut one or multiple shapefiles into tiles of regular size and alignment.

 

Technical Note

 

The tool cuts the input shapefiles into tiles with size and alignment defined by the respective fields.

By setting different values in the panel fields it is possible to define the tiles as squares or rectangles by using equal or different latitude and longitude values respectively.

The tool gives the opportunity to select the grid to which the tiles should be aligned by setting the respective alignment parameters. Moreover, it is possible to create a GeoDataBase (.gdb) file for every output tile.

 

The output files names contains the coordinates of their top leftmost point in the alignment grid.

 

Please note: Once the output is created, the maximum number of files that can be opened is 130 due to the open capabilities files number of files opened in Windows (130x3 considering all the auxiliary files for single shape as .shp, .shx, .dbf). If the value exceeds 130, the process may slow down.

Please note that due to the limitations of the shapefile format, the DBF can have a maximum size of 2GB. If the tile that has been cut exceeds 2GB, a warning will appear, but the process will complete. However, the written values may be corrupted.

 

Input Files

 

Input Shape Files

File name(s) of the input shapes to cut. This file is mandatory, the shapefiles must contain only point features.

 

Parameters - Principal Parameters

 

Output format

Choose the output file format.

 

Tile Lon size (m)

Tile size in the Longitude coordinate in meters.

 

Tile Lat size (m)

Tile size in the Latitude coordinate in meters.

 

Tile Offset Lon (m)

Tile alignment of the tile in the Longitude coordinate in meters.

 

Tile Offset Lat (m)

Tile alignment of the tile in the Latitude coordinate in meters.

 

Delete temp shape files

By setting this flag the shape files are deleted because they are included in the .gdb file.

 

Remove points outside shape mask

This field get activated only if the user insert a Shape Mask file under the Optional Files tab. By setting this flag the PS/SBAS points located outside the mask will be deleted.

 

ID Prefix

This field get activated only if the user select GDB as output format. It correspond to the Unique ID (UID) that will be reported inside the attribute table of the created GDB file.

 

Apply Coherence Threshold

Set this field to True to apply a coherence threshold on the input point shapefile. Insert a coherence threshold in the Coherence threshold value field.

 

Classification Classes

Enter the IDs of the classes of interest. Points that fall within these classes will be retained in the output file, while points belonging to other class IDs will be removed from the result.
