That's not what I want, I want it to slowly become less.</SPAN><BR /><SPAN>For example, the point has a value of 200. After the point to raster tool, the cell in the raster has got a value of 200. A cell next to this one has a value of 0, but I want this value to be (for example) 195.</SPAN><BR /><SPAN>How can i do that?</SPAN><BR /><BR /><SPAN>I hope someone can help me.</SPAN><BR /><SPAN>(I use ArcGIS 9.3 with the Spatial Analyst &amp; Data Interoperability Extensions)</SPAN><BR /><BR /><SPAN>Joost</SPAN></BODY></HTML> Wed, 17 Aug 2011 07:01:21 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-raster-out-of-points/m-p/72549#M989 JoostBrama 2011-08-17T07:01:21Z Re: Creating raster out of points https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-raster-out-of-points/m-p/72550#M990 <HTML><HEAD></HEAD><BODY><SPAN>What you are looking to do sounds like </SPAN><A href="http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?id=6269&amp;pid=6268&amp;topicname=An_overview_of_the_Interpolation_tools">interpolation</A><SPAN>.&nbsp; I would recommend taking a look at the different interpolation tools, which will fill in the gaps between the points.&nbsp; Or perhaps the </SPAN><A href="http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?id=6192&amp;pid=6188&amp;topicname=Point_Density">point density</A><SPAN> tool will work, depending on your analysis.</SPAN></BODY></HTML> Wed, 17 Aug 2011 11:18:03 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-raster-out-of-points/m-p/72550#M990 JeffreySwain 2011-08-17T11:18:03Z Re: Creating raster out of points https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-raster-out-of-points/m-p/72551#M991 <HTML><HEAD></HEAD><BODY><SPAN>Thanks, that's what I was looking for.</SPAN><BR /><SPAN>Next problem is how I get a larger extent then just the 4 points with the largest and lowest X &amp; Y.</SPAN><BR /><SPAN>Can I put in a border or something?</SPAN></BODY></HTML> Wed, 17 Aug 2011 11:45:23 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-raster-out-of-points/m-p/72551#M991 JoostBrama 2011-08-17T11:45:23Z Re: Creating raster out of points https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-raster-out-of-points/m-p/72552#M992 <HTML><HEAD></HEAD><BODY><SPAN>All tools in Arctoolbox have the often-overlooked "Environments" tab, this is where you should be setting cell size, analysis extents etc etc. prior to clicking any OK button</SPAN></BODY></HTML> Wed, 17 Aug 2011 12:32:17 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-raster-out-of-points/m-p/72552#M992 DanPatterson_Retired 2011-08-17T12:32:17Z Re: Creating raster out of points https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-raster-out-of-points/m-p/72553#M993 <HTML><HEAD></HEAD><BODY><SPAN>Dan &amp; Jeff,</SPAN><BR /><BR /><SPAN>I've worked it out.
