People at sohu say this setting is useful because the result of the query, rounded up with python's round function, takes three times longer than all the other commands combined.It's a question someone on StackOverflow asked.

The gdal/swig/python/samples/ogr_layer_algebra.py should be promoted to an official Python script

Steps:

• move it to gdal/swig/python/scripts
• create a new test script for it in autotest/pyscripts/test_ogr_layer_algebra.py
• write a documentation page in doc/source/programs/ogr_layer_algebra (and link it to the index)

We should add type aliases like type UnitVector3<N> = Unit<Matrix<N, U3, U1, Owned<N, U3, U1>>>; to simplify their uses, e.g., in SIMD code: UnitVector3::from([v1, v2, v3, v4]).

When I edit a polygon with a zoom level low and I snap this polygon to another one, it's very common the created snap point is not exactly on the line / point.
For me, it's a problem regarding I control if these polygons are not intersecting.

it's possible to set fill color clicking on right click on the mouse?

Add Runnable links of the code below the example.
Use link name Run Code which links to a Online C++ complier conatining the example code.
Use Rextester as the Online C++ Compiler (If you have a better suggesstion please comment).

Follow below steps to generate the Run Code Link.

1. Go to Rextester
2. Copy or write the example

An option like $ fio cat --bounds w s e n --bounds-crs <crs> --dst-crs <crs> would allow for filtering prior to reprojection, like $ ogr2ogr -spat w s e n -spat_srs <crs>.

See Toblerity/Fiona#210 for a discussion about standardizing bounding boxes as --bounds w s e n rather than --bbox w,s,e,n.
