Mr. Rahman has extensive experience in the field of GIS, Information Technology, Climate Change, agriculture, Water Resources Planning, Management, and development projects in Bangladesh. He is experienced in developing multi-sectoral databases such as water, agricultural, geospatial census, and climate change in Bangladesh. He is working with a multidisciplinary team on specialized projects conducting analysis on environmental and social issues, agriculture, water resource planning, hydrology, database development, land suitability analysis, etc. During the analytical process, he uses a set of technical tools such as GIS and RS-oriented applications, information technology as well as social tools such as questionnaire surveys, stakeholder consultation, etc. He is experienced to assess natural resources using GIS and RS techniques. He is skilled and capable of making effective use of GIS and RS analysis in solving spatial problems. Mr. Rahman has expertise in developing delta Atlas for Bangladesh Delta Plan 2100 which is accessible through touch table technology and geo-portal. He is experienced in EIA, IEE, and RP study in different projects conducted by CEGIS. The responsibilities covered the overall planning to design of the desktop and web-based GIS application, system Analysis and design, supervising the process and software development, GIS analysis project management, work plan preparation, presentation, and reporting. Moreover, responsible for developing a spatial database to use GIS as a planning tool in Vector GIS i.e. acquiring data, making data usable, structuring databases, analyzing database, cartographic design for display presentation, and hard copy map production. Quality checking of spatial and attribute data. He is working with a group of professionals and guiding them to create different spatial and non-spatial data layers to fit into a relational database and GIS interface; so that users can handle different layers of information. Cartographic design for display presentation and hard copy map production. Developed map template and symbolization for the National water resources database. Also providing technical solutions to the programmers and the GIS professionals on technical issues for GIS database development, management, and maintenance. Also, responsible for a broad range of data analysis for the water resources planners. Frequently work does computer-based hydro-meteorological data analysis (viz. Frequency analysis of flood flow, flood level, low flows, rainfall, etc.), topographical data analysis, and preparation of area-elevation curve, cross-section profile, long section profile, and flood depth map. He is experienced in DGPS/ GPS field surveys for image geo-referencing, quality checking and updating of geo-spatial data sets. He is, also, preparing project proposals, technical notes, developing metadatabase, preparing project concept notes, project completion reports, Data sharing, and ownership policy formulation, presentations for workshops and reports. He is extensively used to the GIS software of ArcGIS10.3, ArcInfo, Eardas Imagine and ArcView.
