====== Compare Vector Datasets ======

This page describes how to use the vector comparison toolset.

This tool allows the spatial comparison of two vector dataset.\\

===== Concepts =====

Vector dataset comparison tool ingests two vector files and output one vector files containing spatial comparison insights.
It scans //Source// datasets and scans each entry's location to find a correspondence in //Compare// dataset

===== Sidebar =====

==== Source ====

Reference or Ground Truth vector dataset. The dataset against which comparison will be executed

==== Compare ====
Comparison candidate. The dataset that will be compared against //Source//.

==== Target ==== 
Name, location and CRS of the vector file resulting from the comparison

==== Options ====
Comparison will be driven following few options: {{:262:desktop:tools:vector_comparison.png?150 |}}
  * Spatial match: Either compare two datasets in 2D or 3D space. Comparing in 2D can be relevant when Z-value is not important or missing from one  dataset.
  * Distance: Tolerance value within which two entries from //Source// and //Compare// will be considered as a match. Beyond this distance and in absence of any correspondence, comparison will mark it as not-a-match.
  * Choose //source// or //compare// attribute: Constraint the spatial comparison to entries wearing the same class attribute in both //Source// and //Compare// datasets.


==== Output ====
Output will be a vector file on-boarding attribute that will allow visual comparison by adjusting legend display.\\ {{:262:desktop:tools:vector_comparison_output.png?800 |}}
