Can you please fix the following assess

Can you add an english description.

How different is the accuracy assessment as offered by other plugin ie Semi Automated Clasiffication

rdominguez10 commented 4 years ago

Hello NyakudyaA. Thank you for your comments.

Some time ago the idea of ​​creating this plugin was born because there was no approach similar to that used by Olofsson, I think that in these new updates of Semiautomatic it has implemented it, these days I have tried to execute the accuracy with semiautimatic but I have not had any results yet because it still doesn't work well, also semiautomatic only works with rasters and this plugin can be run in vector format. Finally, we want this plugin to grow with more functions, to make it a powerful tool.

I already put the description in English and add the home page

Thanks a lot. Have you looked at https://plugins.qgis.org/plugins/AcATaMa/ to see if it doesn't do what your plugin does. We try to eliminate duplication and foster cooperation unless the tools are different in methodology. If the scope is along the same lines maybe I can initiate collaboration

Hi @NyakudyaA Sorry for responding until this time, I've had a lot of work.We just updated the MapAccurAssess plugin, we added a module for sample generation based on a stratified random design. Answering the question about what advantages this plugin has over the existing ones: I will tell you, this plugin uses the standard formats (shapefile and geotiff). It performs the calculation of the sample size within the plugin itself, so the user does not have to use other tools such as spreadsheets or statistical programs and the creation of random sites are generated simultaneously for all classes. So far the random sites are a vector of points, but this allows the user to decide the spatial unit to be used (points or polygons with a given area). The sampling design is based on Cochran's method (1977), so the sample size (number of sites) is related to the total area and the expected accuracy of the class, the latter is assigned by the user, and the distance between points is conditioned in order to avoid unnecessary effort in rare or small classes. On the other hand the plugin is composed of two tools, whose operation is sequential but not dependent on each other, so if the user already has a file containing your reference data (random sites with the reference class), you can generate the confusion matrix and accuracy estimation. 

Regards Roberto.
