Accuracy Assessment of an Image Classification in ArcMap

[@mayrabarral6594]

Huge thanks!! You just saved my academic life.

[@Vishal54438]

Thanks a lot... You have explained it in so easy way... Very easy to work out as per your instructions...

[@gidadokabeer6302]

Nice tutorial. But how did you get the reference _point 2 to display? Thank you

[@buklind]

Please do you have a written version of this tutorial?

[@sholagberutaofeeq4393]

Good presentation. . . . .

[@geovenandrea3384]

HI! thanks in advance for sharing

[@TheMohsennabil]

Really thank you very much. the video helps me a lot

[@ahmedmashharawi1]

You are wrong answer .. When the equation is applied, the result becomes 0.65 Kappa = 0.65

[@w17h0u754n17y]

Awesome tutorial, thanks!

[@i_m_pratt_bratt]

How the point shapefiles were drawn down by down, like pastures water etc . how to add points to next class, mine coming in one shapefile , not 4 like the video, plz ans

[@buklind]

Hi thanks for your tutorial. I would like to know if the original Landsat image you used for the accuracy assessment was the same as the one you used to conduct the classification? Thanks

[@irshadsahil2097]

thankxx for info. so i have alittle bit of confusion abut the Accuracy Assesment. hw ,plz explain in simple way...

[@nyomanartosuprapto8967]

Its nice and very good tutorial. But if i want to make a validation using the real data field. How i should define the distribution of data field? Thank you

[@MounirKarim7]

Very useful, thanks.

[@Husamadin]

thanks for this great explination, and please, could you tell me about the reference which report the number of reference points for each class??

[@hamimuidrisa6390]

Thanks, but how did you get that matrix table?

[@ernestg7466]

Muchas gracias, genial el tutorial :)

[@jorgecaballero3445]

How did you get the combine table?...because the output from the combine tool is a raster

[@furuka]

+Jorge Caballero I have the same doubt.. did you figure it out?

[@souleymanecisse803]

+Jorge Caballero Just try to change the points into raster and combine the two layers.

[@77cobby]

It should be a raster. She is showing the attribute table which she later exported into a dBase table which she named CombineTable.

[@asifishtiaque4840]

Combine table is just the attribute table of Combine raster.

[@cindynguku2409]

how did the raster test points layer get displayed into the different classes coz mine is a greyscale color ramp

[@tseveengerelbatnyam291]

Thank you! Very much

[@abebemulugeta4622]

thanks i found it useful.

[@hakiyusdinar_bgr1]

Good presentation. . . . .may ihave a pdf version of this tutorial, please ?

[@josephngyabiya2269]

thanks for the tutorial.....

[@bernardasiedu8828]

This has been useful, but my Pivot table does not display well in excel when i export, no columns just a jumble of numbers, although i used the comma, all files format. I am sure missing something. Any ideas

[@tessboada3373]

Are there commas mixed in with the numbers? you may need to go to the Data tab and use the Text to columns tool to separate the numbers based on the columns.

[@bernardasiedu8828]

Thanks Tess, i used the Text import wizard in Excel and have been able to solve it. Very nice of you though.

[@mayararocha7742]

Hello ... I need to make a matrix of confusion and kappa index, help me

[@NandaMineirissima]

Thanks a lot!

[@jairofelipecamargo2404]

muchas gracias

[@mahadeibnsalam6735]

Combining reference points and classified images didn't work for me. Didn't get the expected table. what to do

[@77cobby]

What did your table look like? I was confused at first, too, because my table had more columns than hers. However, this was correct and made sense because I had more land cover types than her.

[@mahadeibnsalam6735]

the column for classified image is not showing up...i did a MNDWI(modified normalized water index)and supervised classification to separate land and water

[@mahadeibnsalam6735]

It worked!!!!! the problem was that i used another software rather than arc gis for supervised classification.. i re worked the classification in arc gis and then the combined thing just worked like a charm !!!

[@JocileneDB]

Muito bom! Obrigada :)

[@nayannebenfica6265]

Joci, boa noite. Vi que vc também ta tentando fazer a amostra dos pontos. Depois que ela faz o da agua vc entendeu qual procedimento??? No video so aparece todas as amostras.

[@JocileneDB]

Boa tarde Nayanne, faz um tempo que vi esse vídeo. Poderia indicar a parte do vídeo que ela mostra isso? Tentarei responder se souber.

[@mayararocha7742]

Nayanne... Você conseguir fazer a matriz de confusão e calcular o Índice de Kappa?

[@afeworkabate810]

pls any one how to select multiple point on suitable site selection

[@GregBreak]

reference for k-coefficient?
