8.2.13.1 Satellite Imagery


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 UTM 30 projection, convert to UTM 30: Drawing Tools > Projections & Conversions > Map conversion: Raster > Single / Many maps (see Chapter 8.2.11)

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

  • a) Tiles:


4. If the image(s) are not already in standard LUPMIS tiles, cut to tiles: Drawing Tools > Other GIS Tools > Satellite imagery > Cut to tiles (mosaic) > Single / Many maps: 




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: Drawing Tools > Other GIS Tools > Satellite imagery > Merge tiles (overview):




Example of Dodowa 2014:




  • c) Index:


6. Index photos/topos: Drawing > Other GIS Tools > Satellite imagery > 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 Drawing Tools > Other GIS Tools > Satellite imagery > Info about satellite imagery:



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