USE OF SATELLITE RADAR DATA

 

We are experienced in use of SAR data for open land, forest and marine filaments.

From an ESA grant we have revealed the possibilities to map i.e. biological rich

farmland areas of eastern Europe.

 

   

 

For analysing the distribution of biological rich grass land areas a PCA analysis of

8 ERS-SAR images from two seasons (1997-98) was made and has been categorised

into four classes: Crops (beige), grass / abandon (red), moist grass/abandon

(dark blue) and forest. CORINE land cover level 1 has been overlaid forest (green)

and wetland (light bluish).

 

   

 

To predict next years land use intensity, ERS SAR image is used for monitoring

cropping in a rural area in Latvia. White areas in the farmland indicates ploughed

areas or areas to be spring crops, black areas are seedbeds for winter crop.
