If any ground should only be allocated to a single polygon, then a polygon overlay tool like Union which creates coplanar polygons would be the first tool which I think you should test to see if it meets your requirements.

The issue was reported and fixed in hub.qgis.org/issues/13114: It was wrongly using comma instead of semicolon to separate values

You can't in ArcGIS. The MrSID format is read only. If you want to output to sid, you need to purchase the LizardTech MrSID encoder, or find some other software that incorporates this proprietary encoder (I think you can write to sid with GDAL if you compile the MrSID driver against a purchased LizardTech encoding SDK).

Convert the red cells to centroids (points, inside) preserving the unique ID. Spatial Join the red points to the white polygons. Start the join from the red points from step 1 to the white polygons. Now the red centroid points have all the white data in them. Using the right click spatial location join is fine. Now Attribute Join the red polygons to the red ...

Without coding, it could be time-consuming. Either way, the steps would be to add a field to each shapefile and populate each feature with the shapefile's name. Here's a sample script, to give you an idea, if you'd like to try coding. import arcpy import os # Set the ArcPy workspace to the directory that contains your input shapefiles arcpy.env.workspace = ...

Try Zonal Statistics or Zonal Statistics as Table Tool. The first I mentioned works with input raster dataset that you want to calculate statistics from and raster dataset or feature class that defines the zones. Only one statistics a ta time is supported here and you can select it from the drop-down menu. Result is raster dataset I think with the ...

It would be helpful if you posted your code. There is now a special merge function that is called for sp class objects that addresses the sorting issues with base merge breaking the slot relationships. You can bring up help for the sp version of merge using ?sp::merge. The slot id should be the same as the rownames in the @data slot. As such, you can use ...

Under ArcMap: Toolbox\Multidimension tools\Make netCDF Raster Layer: Raster layer will appear in TOC of map document In ArcMap-document TOC: Right click the Raster layer entry and convert to e.g. TIFF-file. I do not think that you can convert straight away to ESRI-GRID-format Toolbox\Conversion tools\ToRaster\Raster to other format (multiple): choose ESRI ...

I guess you are using Landsat 8 product from my experience, it should be: band 2 → 1; band 3 → 2; band 4 → 3; band 8 → 4 you can do band combination like RGB (3,2,1) combination and if it show natural color then its true. 4 is for band 8 which is panchromatic band if you are still confuse, you can match the band min_max pixel ...

The first Feature Class you add to the tool defines the output scheme, which is entirely editable. In the Field Map dialog of Merge, you can right-click a field to add input fields or remove fields; under properties, you can change field types, field widths. You can Delete fields for the output. With the plus button, you can add a new field.

In field calculator, if you are merging two text fields, put single or double quotes around each field name. Also, make sure to see the combined length of these two fields do not exceed the length of the column you are calculating on.

I have known this happen due to there being lots of files to merge and the folder and file tree names are long. Resolve by shortening the folder files names. I have it happen for other currently unknown reasons too!
