Round geometry coordinates

Description

Vector data geometries are composed of coordinates with a given number of decimal places. Very often there is for example 15 decimal places accuracy for coordinates that were acquired with one meter accuracy (eg. coordinates collected in the field using GPS). In these cases there is sufficient to decrease accuracy for example to one decimal place and this small adjustment can reduce the file size eg. by 50% and in many cases much more.

Remember that if you reduce the decimal places too much (especially when using the degree coordinate system), then the geometry of some small elements may disappear (the number of vertices in the resulting file may decrease). Eg. for data in degrees the default precision of 5 decimal places roughly equals of precision of about 1.1 m.

Parameters

• Input vector data - Requires polyline or polygon vector data
• Number of decimal places - Round precision of coordinates for vertices of all features to specific number of decimal places. For data in degrees the default precision of 5 decimal places roughly equals of precision of about 1.1 m.
• Output format - Select file format for data to download.
