# Introduction

**LACO-Wiki** is an open access online tool for land cover validation. This document provides an overview of the basic functionality of LACO-Wiki and guides you through uploading and validating a data set.

LACO-Wiki enables you to set-up statistically robust **sampling designs** and then visually interpret the samples in a **user-friendly environment.** You can then generate **state-of-the-art accuracy reports** for communication to map users.

The tool also includes data management and **sharing functionality** so that every data set uploaded or generated in LACO-Wiki can be managed by you and shared with other users.

**Key Features**

LACO-Wiki offers:

1. A single online access point for the complete map validation process.
2. A user-friendly environment to upload new maps and create sampling designs.
3. State-of-the-art accuracy reports generated with just a few clicks.
4. Easy access to shared data sets and validation sessions, allowing users to share the workload with other people in their team so that multiple people can validate a set of samples at the same time.
