Level of expertise required for this Chapter: Advanced; specifically for LUPMIS @ TCPD


8.3.6.1 Processing Steps

a) Tiles

c) Index

General process:



1. Acquire image(s) and copy to photos folder of the District, e.g. C:\LUPMIS\Shama\Shama photos.

2. If the image(s) are not in ECW format, convert to ECW: Processing Tools > Format conversion > Raster > Single / Many maps (see Chapter 8.2.12.4)

3. If the image(s) are not in UTM 30 projection, convert to UTM 30: Processing Tools > Coordinate system conversions > Raster > Single / Many maps (see Chapter 8.2.11)


  • a) Tiles:


4. If the image(s) are not already in standard LUPMIS tiles, cut to tiles: Processing Tools > Raster processing > Tiles & mosaic > Single / All images:




For LUPMIS standard tiles, see also Chapter 8.2.14.


You can select one map or all maps inside a folder. If you select 'Many maps', select the folder and just pick any file, it will then process all image files of that type in the selected folder. This process might take many hours.


Example for tiling a large area to LUPMIS tiles:



Example for re-tiling from a different projection system to LUPMIS tiles (UTM 30):



  • b) Overviews:


5. Create larger-areas 'overviews' for small-scale work: Processing > Raster processing > Merge tiles for overview:




Example of Dodowa 2014:




  • c) Index:


6. Index photos/topos: Processing > Raster processing > Index photos/topos (with map)



After an index has been created (necessary for future processing in LUPMIS), you will have the option to display its grid in the GIS....:





.... or on an Internet maps:

  • d) Image Info:

All information about an image can be retrieved through Processing > Raster processing > Info about satellite imagery:



This will produce an output similar to the one below, with more information in a text file.
