Dear All! 1) I have an .img raster file (8 bit and 1 band) to put inside mapfile. Pixel value goes from 0 to 255 (field value) there are also other filed of information that I want to use to classify my layer. This is a draft of the layer table: OID value sin 0 0 0,002 1 4 0,001 2 8 0,128 .... ... ...... 84 255 0,98
How can I define mapfile to have a "floating" classification? There is an expression to constrict mapserver to use a value field. The other solution is to do 256 classes.... But it's quite long. I found on doc the instruction to use not 8-bit classification. But this 8bit so I need other way. 2) If I want to define a query for the same layer in wich for each pixel appears the voice of "sin" field. I have seen the script for 3 bands; how can I do wit my layer?: Pixel:<br> values=[value_list]<br> value_0=[value_0]<br> value_1=[value_1]<br> value_2=[value_2]<br> RGB = [red],[green],[blue]<p> Class = [class]<br> Thanks.
