Measure Polygons vertices Length??

[sangeethaunni]

Hi All,

How do we get length of each vertex of a selected Polygon?
I have Parcle.shp with AREA & LEN in the .gdb . Now need to show length of each Side of the Selected Parcel.
how do I implement it? Can we have any tool in AGS Desktop 10? or we have to add code in flex?
My scnario as in calhounty parcel search.

Sangeetha.

   You are going to have to be more specific as to what you are trying to do. I can not think of anything on my site that has to do with measuring polygons length.

Thank u for the response

My scenario is as follows:
               Search a Parcel by its parcel ID & highlight the selected polygon. Mean while i want to find the length of each side the selected feature polygon.
I have attached a snap shot of my flex page. In that i could able to add 'short axis X long axis' label by using Azimuth polygon tool.

Can i find length of each side of selected polygon?

Sangeetha,

   Here is a sample app where you draw a polygon on the map and the length of the sides are alerted back to you.

i am looking for similar help. I need to display length of each vertex's in the polygon.  help would be much appreciated. 

[sangeethaunni]

you may use the code provided in the forum .

I forgot what did I do for resolving.

I hope I had used the same code.

[NormandMarchand]

where do i input that code?

[sangeethaunni]

If you are using adobe Flex code for development , you may use this code to

execute it

[NormandMarchand]

also, I don't need to draw in any polygons I just need it to display the length of each polyline in each polygon. 

[NormandMarchand]

i tried the code it did not work
