Questions in topic: "value" https://knowledge.亚搏在线safe.com/questions/topics/single/39688.html The latest questions for the topic "value" Change all raster values of one pixel if all bands all three bands are 0 https://knowledge.亚搏在线safe.com/questions/80380/change-all-raster-values-of-one-pixel-if-all-bands.html

I'm trying to merge different raster features to one image using the overlap value option in the RasterMosaicker.My end goal is to merge these images based on how the look in RGB.The order of the layers is done using the sorter just before the merge.使用透明度是关键，因为当存在“节点数据像素”时，您需要看到不同的层。

The problem i'm facing now is that the NoData values differs with each raster or even that some rasters do not even have a NoData value (even do it should).For the last situation i want to translate the raster a bit so the can be used for a NoData value of 255.By visual inspection i could see that that only the withe (r=0,g=0,b=0)colour needs to be replaced with transparency.

My first step is converting all 255 values in RED8,绿色8和蓝色8到254，所以255被释放。下一步，我只想隐藏红色8，一个像素的绿色8和蓝色8值，三个像素的0值都为255。我尝试使用RasterCellValueReplacer，将0和0之间的设置设置为255，然后将nodata值设置为255，但问题是所有0值都已转换。Meaning that a red area (254,0,0) changes colour.

TLDR: Is there a value mapper kind of tool that could do the following (sudocode) trick:

IF pixel == RED8 = 0 AND GREEN8 = 0 and BLUE8 = 0RED8 = 255 AND GREEN8 = 255 AND BLUE8 = 255 otherwise:Do nothing

我正在使用attributeManager中的条件语句检查该属性是否以字母结尾。Using [a-z] does not seem to work and I am assuming it is because the test sees it as text not a Regular Expression.

有没有办法让它起作用，或者我需要为字母表中的每个字母都设置一个测试子句？

当做

I have a line feature class (with a field SURVEY),我想把它分成两个功能类。In the first one I would have those features that have more than one feature with the same value in the field SURVEY - and in the other one - those features that have a single entry for a value in the field SURVEY.

I believe I could explode the original Feature class by the value in the SURVEY field,then count features in each of them,then test for value "1" and merge if required.但我不知道如何根据字段中的值创建单独的功能。

Just to give you a context: For the first one I will later create convex hulls based on field SURVEY,but for the other one - buffers (as the convex hulls wouldn't look too good for a single lines).But this is not part of the question - as I know how to do it.

Please advise.

I am flattening a complex 3D building into its outline and then I want to use its max height to extrude the footprint.在我想使用提取的最大高度作为挤出变量之前，这是有效的；instead of just using the value,the AttributeCreator (NA: ExtrudeHeight,av:_max）创建两个功能，一个只有挤出属性+值，and the other with just the attribute,but empty.How do I just write the number into the attribute field of the geometry?

Hi there,

I've been struggling for a while now to generate stats in the way I want to for a few specific Shape files I have.I've tried toying around with the statistic calculator for a while,but not getting exactly what I need.

所以，作为我的shapefile内容的表示，here's an example of what I have:

Type Color Size Shape 米
A 红色 SML TRI 11
A 红色 SML RND 十五
A 红色 MED RND 10
乙 红色 MED RND 20
乙 红色 LRG RND 十三
乙 Blue LRG RND 16
C Blue SML SQR 14
C Blue SML SQR 19
C Green MED TRI 十七


And here's what I'd like to have as an output (aiming for a plain excel sheet):

Item 价值 米 伯爵
Type A 36 三
Type 乙 四十九 三
Type C 50 三
Color 红色 69 五
Color Blue 四十九 三
Color Green 十七 1
Size SML 四十九 4
Size MED 四十七 三
Size LRG 29 2
Shape TRI 28 2
Shape RND 七十四 五
Shape SQR 33 2

Basically I just want the counts and total measurements (I already have the METERS attribute in my source) for each unique value for specified attributes (like Color,or Value etc..)

事实上，我可能会在“项目”上做一个扇出，以减少纸张的厚重感，but that I already know how to do.

Please feel free to ask if there's anything else I need to explain in more detail.

Thanks in advance,

Dear FME-Users,

I've 3 input rasters with the same CRS,扩展和解决。

The aim is to get 1 output raster by combining all pixel values.

For each pixel the highest value from the import rasters should be used.

在附件中你会发现3个光栅。The color cyan is "low" and the colors to red are "higher".

你有主意吗？

非常感谢。

最好的问候！
