The major projects undertaken by the Centre are the following.
1. Land use survey of Idukki district using remote sensing techniques. The project was completed in 1981 with the objective to evolve a land use Plan for the district for land use planning and natural resource management for sustainable development using panchromatic black and white and colour Infra Red (CIR) aerial photographs on 1:15,000 scale. The study carried out in collaboration with space Application Centre (SAC), Ahamedabad, incidentally was the first of its kind carried out in the State using remote sensing. Integrating the generated thematic maps on land use, geomorphology, structural maps, soil conservation priority map and optimum land use map, a comprehensive Land use Plan for the district was evolved on 1:15,000 scale for use of line department and user agencies.
2. Nation wide Land use/Land cover Mapping project. Land use/land cover mapping of the entire State was carried out by the visual interpretation (1:250,000 scale) of IRS IA satellite images. A district wise Land use./land cover map of the State with 24 categories up to level II has been generated as part of collaborative project of National Remote Sensing Agency, Hyderabad (DOS) for agro-climate zone planning by the Planning Commission of India.
3. Identification and Mapping of Waste Land using Land at TM images of 1:50,000 scale. The waste land of six critical districts of Kasargod, Kannur, Malappuram, Wayanad, Palakkad and Idukki districts were mapped and classified based on the categories developed by the national Waste Land Board and has been spatially delineated village wise by visual interpretation of TM images on 1:50,000 scale.
4. Integrated mission for sustainable development (IMSD) Under the study, comprehensive assessment of the status of natural resources like soil, hydro geomorphology, surface and ground water potential, agriculture, forest. Land use/land cover, infrastructure assets facilities, etc and done. Thematic layers on the above were generated by visual interpretation IRS satellite data of relevant dates coupled with ground truth obtained through filed checks based on the technical guide lines supplied by NRSA. Later integration of the thematic maps are done to arrive at location specific action plan for the sustainable development of the study area. The repot and maps were prepared on 1:50,000 scale. The study has been completed for district on Palakkad, Kasaragod and watersheds on Payaswini of Kasargod district and Thrikkulam of Malappuram district in first phase and the report and maps are published. Study in Thrissur district and watershed on Ranni in Pathanamthitta district and Perumbra in Kozhikkode district has been completed.
5. A Study was under taken by the Forest survey of India to map the Forest cover of the country using satellite remote sensing. The ground truth support of the project for the State was done by the Land Use Board in collaboration with the State Forest department.
6. A pilot study was conducted in Bedadka and Munnad village of Kasaragod district to map the different classes of waste lands at micro level using 1:15.000 B/W aerial photographs.
7. Satellite monitoring of Malampuzha Irrigation Command was carried out to assess the progression of irrigation across the command as well to assess the ayacut area and yield forecast during Rabi season of 1993-94 as part of the NWMP.
8. Coconut Crop Inventory of the districts of Alapuzha, kottayam and Idukki districts were done by interpretation of Satellite image and CIR aerial photographs in collaboration with Space Application Centre, Ahemedabad.
9. Mapping of the present Land Use Pattern of Proposed command of the Vamanapuram Irrigation was carried out using remote sensing techniques and GIS.

Thiruvananthapuram, Kollam, Pathanamthitta, Kottayam, Alappuzha, Ernakulam, Thrissur, and Kozhikode was carried out by interpretation of satellite images and final output brought in ditigal format. The study was done in collaboration with NRSA, Hyderabad, Earlier the remaining six districts were mapped and thus the wasteland mapping of the whole State in 1:50,000 scale is completed.
11. Land Degradation (Land Slides) in Kerala. The objective of the study was to provide a general understanding of the land slide problem of the State and identify potential landslide areas. The report of the study conducted in 1996 brought out different case studies on land slides in the State, land slide occurrence in the State and categorized the land slide hazard risk zones of the State spatially at 1:250,000 scale.
12. Study of the culturable waste lands, its magnitude and extent. This was a sponsored project of Ministry of Agriculture, Government of India with the objective to make realistic assessment of the culturable wastelands of the State in terms of its type, magnitude and extent and ascertain the reasons for not cultivating the land. The report of the study presented the extent of distribution of the classes of culturable waste and in each district giving factual data for land use planning at micro-level.
13. A Wasteland Atlas of the forty four river basins of the state on 1.50,000 scale was prepared and published which cater the needs of the line departments to have uniformity watershed delineation when chalking out watershed management and development pogrammes.
