Mar 1	comment	What projection is this and how to use it in a GIS? I've managed to find and contact the author. It appeared that it's his own devise. So it rather will not be possible to reproduce it with standard tools.
Mar 1	comment	ArcGIS key numbering labels for every feature in one layer Thanks for answer. There's no possibility to remove strategies from Strategy Order. So it left me to create numbering as attribute and manually add table with numbers and description.
Sep 20	comment	How to prevent running part of a model when iterator is used? Thanks for useful hint Blah. I've even tried nesting models, but nested wrong part.
Jul 16	comment	How to calculate XY coordinates in Decimal Degrees from projected dataset in model or script? @mburkenysdot: This is a good workaround when someone doesn't want to use any scripting.
Jul 16	comment	How to calculate XY coordinates in Decimal Degrees from projected dataset in model or script? @iRfAn: I thought that there's some more straightforward solution, but your's works perfectly. Thanks:)
Jul 13	comment	How to calculate XY coordinates in Decimal Degrees from projected dataset in model or script? @Roy: yes, I want to preserve a feature class in projected CS, but calculated decimal degrees.
Jul 9	comment	How to fill Field Mappings parameter in script tool on updateParameters? Thanks, this works:)
Jul 9	comment	How to fill Field Mappings parameter in script tool on updateParameters? I know it. But I want to be able to select more than one field.
Jun 22	comment	How to update geometry in ArcObjects? @vinayan, @whuber - but which `IAffineTransformation2D` method should I use? I haven't found one with such set of parameters.
Jun 22	comment	How to update geometry in ArcObjects? Thanks again. Now it works for simple polygons (multipart and with void polygons are not recreated correctly) and is good starting point for futher development.
Jun 21	comment	How to update geometry in ArcObjects? I've posted adapted code as Edit - it compiles but does nothing.
Jun 21	comment	How to update geometry in ArcObjects? Thanks for this code. Unfortunately I'm stuck in `foreach` loop. I get error: foreach statement cannot operate on variables of type 'ESRI.ArcGIS.Geometry.IPointCollection'. Do you know how to fix it?
Apr 18	comment	Can a new point automatically be populated with data from the containing polygon @Hairy: I understood that there're 2 polygon layers, each with more than 2 polygons - for 2 polygon features ther's no sense to use any tool beyond Idetify:) But I agree that for simpler geometries your code is more clear.
Apr 18	comment	Can a new point automatically be populated with data from the containing polygon @Hairy: I think your criticism is unmerited. I've made some tests: 17 random points, 170k polygons in FGDB. Your code ~13min, my ~0.5min. I suppose that avoid looping through polygon layer several times makes the difference.
Apr 18	comment	Can a new point automatically be populated with data from the containing polygon The solution is basen on exercise from PennState: e-education.psu.edu/geog485/node/159. Moreover, On the first place I proposed two ArcGIS tools which do not require any scripting!
Apr 17	comment	Can a new point automatically be populated with data from the containing polygon @Hairy: Your script updates a polygon layer not points. The `geom` variable wont be created as you don't have access to X,Y directly. Use `geom = row.Shape.getPart()` instead. Moreover, the script may not be effective while many polygon as it loops through all polygons for each point.
Apr 15	comment	How to Clip a Vector File based on certain Raster Values? My first thought was also CON tool. But in my created Slope rasters this tool didn't recognise VALUE field. That's why I recommended Reclassify tool. BTW the real problem here is not HOW, but operations on huge vector layers.
Apr 12	comment	How to Clip a Vector File based on certain Raster Values? Have you seen gis.stackexchange.com/questions/16110/… for some hints on handling big rasters and vectors?
Apr 12	comment	How to Clip a Vector File based on certain Raster Values? What do you mean '"Clip" crashes'? Does it throw any errors or ArcMap is in No response state?
Apr 12	comment	How to Clip a Vector File based on certain Raster Values? When converting raster to polygon, select option 'Simplify polygons' - this reduce the number of polygon vertices. Moreover, try to do your analyse in File Geodatabase.
