topic Mosaic Dataset is the Answer, Good job! in Data Management Questions https://community.esri.com/t5/data-management-questions/create-a-rectangle-cell-raster/m-p/348191#M19939 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>Mosaic Dataset is the answer for my last post. It is just as the HELP says "It is a data model within the geodatabase that is a hybrid of a raster catalog and raster dataset". The Hybrid is the key word. You can not project a Raster catalog but can project a Mosaic Dataset without mosaicing, that is a wonderful idea and save a lot of time! Good job! </SPAN><BR /><BR /><SPAN>The terrain data model is the best for the Lidar and Mosaic Dataset is the best for the Rasters. It is always nice to learn those new things from ESRI.</SPAN><BR /><BR /><SPAN>Here is the steps:</SPAN><BR /><SPAN>create a Mosaic Dataset, load all the ortho tifs, poroject it to geographic coordinate system, then load it to ArcMAP and export it by setting a rectangle cell size by 2.2e-006, 1.8e-006, that is all, no any extra process.</SPAN><BR /><SPAN>But I do not know why you can not enter 0.0000022 directly to the Cell Size (cx, cy) box, it is automatically converted to 2.22e-005, this is not good, hope it can be fixed soon.</SPAN><BR /><BR /><SPAN>Best regards,</SPAN><BR /><BR /><SPAN>Wentao</SPAN><BR /><SPAN>KKC, Tokyo, Japan</SPAN></BODY></HTML> Thu, 11 Mar 2010 04:38:02 GMT WentaoChe 2010-03-11T04:38:02Z Create a rectangle cell Raster https://community.esri.com/t5/data-management-questions/create-a-rectangle-cell-raster/m-p/348190#M19938 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I need to create a rectangle cell raster in geographic coordinate system, such as a cell in size of 0.0000022 x 0.0000018 degree, that is about 20cm x 20cm on ground.</SPAN><BR /><BR /><SPAN>I can create this kind of raster using the ArcMAP Mosaic Raster Catalog menu from a Raster Catalog in a file geodatabase. It seems that you can not create an Unmanaged raster catalog from a raster that is already existed in a file geodatabase, I tried several times, all failed. For this reason, I need to create a Managed Raster Catalog, this means I need to duplicate the raster that are already projected to geographic coordinate system, when this raster is big, it takes a long time to do so.</SPAN><BR /><BR /><SPAN>Resample Tool can not create a rectangle cell raster now, I hope it works in the next release.</SPAN><BR /><BR /><SPAN>Best regards,</SPAN><BR /><BR /><SPAN>Wentao</SPAN><BR /><SPAN>KKC, Tokyo, Japan</SPAN></BODY></HTML> Thu, 11 Mar 2010 03:00:16 GMT https://community.esri.com/t5/data-management-questions/create-a-rectangle-cell-raster/m-p/348190#M19938 WentaoChe 2010-03-11T03:00:16Z Mosaic Dataset is the Answer, Good job! https://community.esri.com/t5/data-management-questions/create-a-rectangle-cell-raster/m-p/348191#M19939 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>Mosaic Dataset is the answer for my last post.
