Background
• One of the Six Research Data Repositories of ICAR KRISHI Portal
• Aims to provide a digital platform in public domain to
- to facilitate generation and compilation of data of agriculture having spatial context
- to store/host spatial database generated in NARS- to provide visualization of spatial data as maps with contextual attributes
- to assimilate existing spatial agricultural data from other
sources
- to provide tools for analysis of spatial data
- to allow spatial data access and sharing to clients across platform and GIS flavours
- strengthen in-house technical capabilities

• Practice and sensitize “Data Openness”.• Identify Spatial Data of your Subject Matter / Commodity
– Generated in your institutes, – Generated in allied institutes– Available in public domain
• Identify Tabular Data with spatial context – Current – Historical
• Digitization / reformatting of identified data• Be meticulous in generating “Metadata” of spatial data• Now on always generate data with precise “Geolocation”
– Experimental, Observational, Survey
• Be an active partner of team KRISHI
Way Forward

Issues
• Procurement of base layer data from Survey of India• Open Source vs Commercial Geoserver• How many concurrent users to be served? • Redundancy of Geoportal• Security of Data• Availability of Data to ICAR users / General users• Disclaimer about boundaries, geolocation, administrative
boundaries etc.
