comment Converting point data into a weighted raster
Ive passed this information along but we haven't had time to test it yet! But when we do i can try this and accept an answer!

this sounds pretty good! I will test it out tomorrow and let you know! thank you!!!

comment Converting point data into a weighted raster
this does sound like a good method! ..Do you know which bits i would need to script? I've only ever done some very, very basic python scripting before!

comment Converting point data into a weighted raster
What i have been thinking is that i would build a formula based on the DIFFERENCE between the 2 numbers, so if there was a difference of 0 (in the case of -20 and -20), then the buffers would start between the two points, but if there was a difference of 1 then the buffer would start 60% between the two points.. i am just wondering how to execute this!

comment Converting point data into a weighted raster
Sorry it has taken so long to reply - i was hoping the problem would just go away but it hasnt! The problem with a formula is that because all points will be relative to each other, there will never be one definitive linear_unit which we can set. e.g. if a -20 and a -20 were next to each other - then the buffer would start equidistance between them, but if -20 and -10 points were next to each other, the -20 buffer would start 75% between it and the -10 point!!

comment Converting point data into a weighted raster
I have just been reading about the voronoi diagram and it does sound like what i am trying to do! And i really like the sound of it being "straight forward" to create!!

I mean the distance between the 2 points.. so if they are 10m away from each other and one is -20 and the other is -25 then the -25 buffer will start 2.5m from the -20 point!

I dont actually have any rules as of yet - today i will work out a definate formula and then get back to you!! Thank you so much for your help!

comment Point to Raster Issues
all of them! All of the statistics tools, and all of the tools which come with 3D analyst! I have tried all combinations i can think of! I think arcmap is freaking out because all of my points are on top of each other (im making a subsoil model) and it is getting confused that way.. but i cant think of a way round this!

comment Displaying z-values in arcscene
In the properties window there is an option which says "Layer features have Z values. Use them for heights", but it is greyed out. I converted my point shape to a layer but it was still greyed out!

comment Setting Rasters to the exact same display
sadly i dont have access to it! Im just looking for a way to do it within arcmap - i suppose i should of said that! I will change my question!

comment Displaying 3D subsoil models in ArcScene
It's exported as an ascii (so terrible) but we have some script which converts to an shapefile - i will try this out thanks!!

comment Two rasters created from the same polygon have different extents?
I have attempted to recreate the raster with using a cell size of 0.01 but this still gives me an upper extent of 503001.535094748!

comment How to use python to turn a .dbf into a shapefile
It turns out i was described the problem incorrectly - its not the .pmf we need to update it is the shapefile! Which we then need to export to the client - do you have any links for this?
