      USE OF SAR DATA TO SPOT GRASS, MEADOWS AND CROP PREPARATION

   

 

We are experienced in use of ERS-SAR data for open land, forest and marine filaments. From an ESA grant we have demonstrated the use of SAR to map biological rich farmland areas in Latvia.

 

 

 

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