This module (Figure 6a) is provided to convert non-spatial locust information into spatial data. It is important to understand the soil-vegetation and climatic information in the locust sight points. The knowledge gained in terms of ground condition during locust reporting helps to build the complex query for habitat suitability analysis. This module generates date wise spatial file dovetailed with field attribute information. Each point entry is automatically projected into desired system and records the data against the point entered. Efforts are ongoing to directly input GPS measurements from field. Besides entry of field points graphically/key board, the module also supports entry of point layers generated outside in ARC/INFO or Arcview environment. User can browse through all the points of sighting and visualize the detailed locust information, edit or update (Figure 6b). For enhancing the referencing capability, layers such as roads, rail, settlement and administrative boundaries can be set in the back environment to precisely ingesting the locust sight point.

From locust sighting files those observations would be sorted where the density of locust are above a certain threshold to be critical. The points, thus identified, are used for generation of buffer of specified width (as per the ground spread). The objective of doing so is to identify the biophysical condition underneath buffer, which is supposed to be critical in terms of locust. The information extracted from the buffer area, is used by the Geo-LIMIS query shell, for habitat suitability analysis.
