May 17, 2017 · After clicking OK we’ve got a new, empty mosaic dataset. Next we need to add some rasters by right-clicking on the dataset name and going to Add Rasters… Since mosaic datasets are geared towards rasters, the options under “Raster Type” feature lots of satellite image formats. For our purposes, “Raster Dataset” will work fine. Jun 14, 2013 · For ArcGIS the CSV file must have a specific structure, for example the first line must contain the field names. Now I use a CSV file in ArcGIS 10.1: I start a blank ArcMap project and load a boundary shapefile and CSV table containing attribute values. Input rasters can be integer or floating point. The weight will be applied to the specified field for the input raster. Fields can be of type short or long integer, double, or float. A useful way to add several rasters together is to input multiple rasters and set all weights equal to 1. The weight values can be any positive or negative decimal ...Having come to GDAl from ArcGIS I disagree with the last paragraph of Matt's answer. Granted, ESRI makes raster geoprocessing very straightforward and until recently I would have agreed with Matt, but if you use GDAl in conjunction with Numpy, you have an armoury that is almost as good as ESRI's and, in some regards, I believe better and faster. The Combine tool takes multiple input rasters and assigns a new value for each unique combination of input values in the output raster. The original cell values from each of the inputs is recorded in the attribute table of the output raster. Additional items are added to the output raster's attribute table—one for each input raster.

You will be adding raster datasets to it in the next steps. When the mosaic dataset is added to the table of contents, it is added as a mosaic layer, which is essentially a special group layer. The top level has the name of the mosaic dataset--Amberg. There are also empty Boundary, Footprint, and Image layers. Add rasters to the mosaic dataset ...Having come to GDAl from ArcGIS I disagree with the last paragraph of Matt's answer.

An ArcGIS user has built a mosaic dataset using 25 rasters. However, upon adding the mosaic dataset to a blank map, the user finds that all rasters are NOT displaying. To troubleshoot the issue, the user zooms to the source resolution of one of the tiles and notices that the raster displays at 1:107000 but NOT at 1:997000. arcgis.raster.functions module¶. Raster functions allow you to define processing operations that will be applied to one or more rasters. These functions are applied to the raster data on the fly as the data is accessed and viewed; therefore, they can be applied quickly without having to endure the time it would otherwise take to create a processed product on disk, for which raster analytics ...

You don't need to iterate through each raster in your list. You just need to provide the tool with the list of rasters one time, and it will add them together.
I ran into the following problem when trying to mosaic several rasters on top of each other. In vv[is.na(vv)] <- getValues(x[[i]])[is.na(vv)] : number of items to replace is not a multiple of replacement length As @Robert Hijmans pointed out, it was likely because of misaligned rasters. To work around this, I had to resample the rasters first

The AddRasters operation is performed on an image service resource. The AddRasters operation adds new rasters to an image service (POST only). The added rasters can be either uploaded items, using the itemIds parameter, or published services, using the serviceUrl parameter. If itemIds is specified, uploaded rasters are copied to the image service's dynamic image workspace location; if the serviceUrl is specified, the image service adds the URL to the mosaic dataset—no raster files are copied.
The dot OVR file here, as a side note, is the pyramids file that gets built by which helps it display rasters at different resolutions more quickly. It's sort of like an index that is uses to display rasters as I zoom in and out. So, then if I add the rest of these, still. And then I zoom out. I can see that it seems like I have six rasters here.
