Hallo Robert, thanks a lot. Now it functions. But what i am interested is the projection. The server projected on the fly, because i have another coordinate system as the maps provided by esri. Ok now. Thanks a lot. I have also seen your example. It´s every time i´m learning a new language. The easiest things i overlook. 🙂 Holm ... View more

Hi Aaron, a good idea. I also looking for a gp widget. The problem is, i just start to beginn creating widget with flex api. Normally i´m a gis expert and a python programmer. But i´m looking for well documeted instructions or tutorials how to built a gp widget. Surely you can look at the sample codes, but it´s more important to understand the structure. so it would be nice if someone can share the experience. I can only the support the question of aaron to support high level steps of making a gp widget. PS: Aaron do you have ever built a query widget? Thanks Holm ... View more

Hallo, First thanks to all the people who wrote a reply. 1) Jeffrey Evans, thanks for your aml file. Unfortunately i do no have a arcinfo workstation. So i have to perform / create this analysis in arcgis itself. 2) Phil Morefield, Sure this would be a solution to run a morans analysis in python. Converting to points is no problems. But my task is to solve such a operation with grid cells. The reasons are due to many thematic maps existing in raster format. 3) William Huber Thanks for your very detailled solution. I have some question. But before i start i will provide a simple example. Example. Let´s imagine a simple 3x3 grid with a indicator transformation to 1 or 0. I had done this before with my rasters. This looks like 1 1 0 0 1 0 0 0 1 For a better understanding i will give names to every cell. a b c d e f g h i My weight w(ij) looks like this: 0.5  0.5  0.5 0.5  1.0  0.5 0.5  0.5  0.5 Ok no i want to calculate the morans So every gridcell should have its own morans. "I" stands for morans between -1 and +1 The result should be like this Ia Ib Ic Id Ie If Ig Ih Ii I have studied your equation. I have attached an example. It is an gdb geodatabase and a weighted kernel. Big letters explains the source or intermediate results and small letters are the operators. TestGrid is the base. Ok lets beginn. Here are the grids. I Denumerator "Denumerator1_Variance" = is the focal (3x3) variance of the values "Denumerator2_Variance_times_DoubleSumWeights" = is the product of "Denumerator1_Variance" and the Doublesum of the 3x3 weight. The doublesum of the weight is 10 (weight matrix above) So the denumerator is solved. But now the numerator. II Numerator. "Numerator1_focalXj" = is the Sum over all neighboring gridcells from exactly one center cell with the weights / weightmatrix. "Numerator2_FocalXj_minus_X = is the subtraction of the value normal x-value from the "Numerator1_FocalXj" grid. "Numerator3_Numerator2_product_TestGrid = is the product of the "Numerator2_FocalXj_minus_X" grid and the normal "TestGrid" "Numerator4_focal_Numerator3" = is the FocalSum of the "Numerator3_product_Numerator2" grid. !!!I used here a focal sum Willima instead of a zonal sum, because i want the morans for every grid cell in a 3x3 neighborhood. i think this should be the correct procedure. "Numerator5_Numerator4_times_8" = is the product of the "Numerator4_focal_Numerator3" grid and the number of neighbors, here 8 neighbors. So we have the numerator. http://forums.arcgis.com/images/icons/icon6.png III Divide The last calculation is: Numerator / Denumerator "Divide" = "Numerator4_focal_Numerator3" grid divide by the "Denumerator2_Variance_times_DoubleSumWeights" grid. this should be the endresult. For me it looks ok. Please test and write me back. Thanks a lot Holm ... View more
