How do I identify pixel values in a Dynamic Service?

NMWater

I have map with a raster image loaded on it. The raster image is in my server as a dynamic service. My question is how or what function can I use so when a user clicks on any point on the map, an actual pixel value would show up in a popup?

Many thanks.

Robert,

I finally got it working.

The following method worked:

result.feature.attributes['Pixel Value']);

Thanks for all your help!

Hi Robert,

I did the following and it returned this.

I believe that I have a syntax error when I use result.PixelValue? Any ideas on what the proper syntax is?

Thanks so much!

Francisco,

Put a console.log in the array to see what the value of the result object is. It is normally the case that you are not access the right object property.

Hi Robert,

I tried using this method but I keep getting this result. I attached a picture of it. Do you have any idea what could be going wrong?

Here is my code:

Thanks!

NM Water,

The way I know to do that is to use the IdentifyTask to get the pixel value.
