# How to run accuracy-assessment tool

Asked by jinkaizhang on 2018-01-05

hello.

I am wondering if anybody can provide the guideline on how to use the desktop version of accuracy assessment tool (https://github.com/openforis/accuracy-assessment).  I have downloaded and set up the program on my computer, but couldnot find any document on how to use the tool.

Thanks,

Jinkai

In addition to Yelena's answer, you can find some specific tutorials for the tool:

- a webinar specially dedicated in June 2017, that you can access here [http://www.gofcgold.wur.nl/redd/training-materials/webinar-series/episode/6][1]
- step by step instructions on how to use the tool:[ https://github.com/openforis/accuracy-assessment/blob/master/presentations/p_sae_design.pdf][2]

Dear Jinkai,

The guide for using the Stratified Area Estimator tools can be found here: [http://www.fao.org/3/a-i5601e.pdf][1]. The methodology is based on the methods detailed in [Olofsson et al 2014][2].
Additionally, you can find instructions within the tool that provide the steps for creating a stratified sample and completing the analysis. 

Best,

Yelena
