{{Аннотация|Reducing the number of points in a curve/polyline.}}

Tool for line simplification/generalization with [http://en.wikipedia.org/wiki/Ramer-Douglas-Peucker_algorithm Douglas–Peucker algorithm] and customizable simplify tolerance.

=== Installation notes ===

Plugin is available via [http://plugins.qgis.org/plugins/plugins.xml official repository].

DPSimplify is designed for QGIS version 1.0.0 and higher. There are no dependencies, all necessary files are included in package.

You can obtain sources from our SVN:

<pre>svn co http://svn.gis-lab.info/dpsimplify dpsimplify</pre>

=== How does it work ===

After plugin installation and startup by clicking button

[[Файл:dpsimplify.png|center]]

main window will appear:

[[Файл:dpsimplify-02.png|center]]

Input layer with features to simplify can be selected from combobox (only polyline layers supported). It is possible to simplify only selected features or whole layer. If checkbox "Save to new file" is checked — new shapefile with simplification results will be created, otherwise existing layer will be changed. It is possible to undo layer modification, but note that this will revert all changes. Simplify tolerance must be in map units (meters or degrees).

When process finished a window with information about number of points in source layer before and after simplification will appear. If the results do not suit you can undo changes without closing plugin, set another tolerance value and run simplification again.

Here is example of DPSimplify usage (green line with red vertex — input layer, blue line — result, tolerance is 500 m)
